Scourge

Chapter 3
Fear is mostly born of ignorance and uncertainty.

1.
On a spring afternoon, the sun shines into the office, and it is so warm that it makes people doze off.

Everyone in the office is busy with the matter at hand, I am holding a letter and visit verification file, and I can't cheer up.Lin Tao was reading a report on a "wrong case", while reading in a low voice netizens' condemnation of the police.Chen Shiyu studied hard with Min Jianxiong's "Behavior Analysis at the Murder Scene".Han Liang secretly played with his snake.Dabao is fine, he seems to be reading posts on the forensic forum, but he can always hear his snoring intermittently.

Although the investigation team of the provincial department takes up more than half of their business trips every year, they still have to work normally for the rest of the time.In the two or three months after the Chinese New Year, the investigation team of the provincial department seems to have entered the "off-season" of work, and has not traveled for more than half a month, which is really a rare peace.

"There is no flaw in the handling of the case, but such a thick letter and visit file has to be checked." I thought to myself.Looking at the piles of reports of grassroots forensic doctors being investigated by the Commission for Discipline Inspection and the Supervision Department, I secretly felt wronged for my colleagues.But after thinking about it, they are much better than the investigators in the acquitted case that Lin Tao read.

In the spirit of "no doubt" in recent years, several cases in the province have been retried because of appeals by the parties, and some cases have even been acquitted.Such cases are called "wronged cases" and will receive widespread media attention and local criminal investigation departments will be condemned.

We also participated in the consultation of several cases, but because of the limited technology at that time, there was really no strong evidence on the scene.Although criminal investigators and technical personnel can confirm in their hearts that the cases are handled correctly, at the legal level, the chain of evidence in these cases [Note: chain of evidence, a legal term, refers to a chain of proof formed by a series of objective facts and objects] is Not perfect.Criminal investigators at the grassroots level are willing to respect the spirit of the law, but they are also very afraid of facing accusations from the outside world.After all, many people don't know that "innocent in the sense of law" is not equal to "innocence in the sense of fact".Once the media reports, they always describe the criminal suspects who are "innocent in the legal sense" as innocent people who are "innocent in the factual sense".They don't care about the core disputes of the case, but care more about whether the police have "extracted a confession by torture."

"Isn't this the case we consulted years ago?" Lin Tao said, "I think the evidence is enough to convict."

"What do you think is useful?" I said with a smile.

"I was found not guilty of killing someone, yet I am so arrogant when I come out." Lin Tao said bitterly.

"Since the court didn't find him a murderer, we can't talk nonsense." I said, "This is the spirit of a legal person."

"Then let him get away with it like this?" Dabao stopped snoring and said.

"These things are a wake-up call for us." I said, "First, we must work harder to improve our capabilities to ensure that key physical evidence can be found in each case to prove the crime. Second, the evidence in each case should be It must be considered from many aspects, and there must be a complete chain of evidence, instead of just focusing on isolated evidence [note: isolated evidence, referring to a single piece of evidence].”

"Don't pay, you ye!" Dabao was struggling to learn Beijing accent, "Don't give us lessons, we just feel that the murderer is allowed to escape the legal punishment by taking advantage of the loopholes, and we feel very uncomfortable."

I flipped through the file in my hand, shook my head with a smile, and said, "We have to believe that people are doing it, and heaven is watching."

"What is God watching? Do your job well, and weave the legal net firmly. Do you still believe in God's punishment? You are the people who do justice for God!" Master opened the door and walked in, holding a document in his hand. folder.

Master usually doesn't come to our office to check posts easily. The most common reason is that there is a sudden and serious case, and it is difficult to fully explain it even on the phone. Master will go downstairs to the investigation team to assign tasks in person.

When I saw Master at this time, I was naturally startled. I thought, I probably won't be able to go home to have dinner with my son at night.Thinking of this in my heart, I still stood up with a playful smile and said, "Master, can you listen to everything next time? I was still educating them to improve their professional quality and cultivate their ability to fight tough battles."

"Don't be poor." Master said, "I'm here today to make an announcement from the Political Department."

"Promote me?" I said, still grinning, "I don't want to be a leader."

"What are you thinking about?" Master gave me a blank look, and said seriously, "In order to keep pace with the times and expand the professionalism of the investigation team of the provincial department, we have decided to organize the selection work across the province. Investigation, refers to the technology of video and image investigation] a professional and technical policeman. After written examinations, interviews, assessments, public announcements and other organizational links, Cheng Ziyan, a policeman from the Criminal Police Detachment of Longpan Public Security Bureau, was selected with a total score of No. 1. Continue here After the notification, the Longpan City Public Security Bureau and the Criminal Police Corps of the Provincial Department immediately went through the transfer procedures for the policeman, and immediately reported to participate in the work. This is hereby notified."

After reading the notice, Master closed the folder and stood there quietly.

The few of us were very surprised, and we haven't recovered for a while.I turned around and looked around, Dabao looked shocked, Han Liang was indifferent, Chen Shiyu looked a little disturbed, but Lin Tao's expression didn't seem to be disturbed at all.It seems that this time the selection, only Lin Tao knew about it in advance, after all, they are professional counterparts.

We all know Cheng Ziyan, and we can often see Cheng Ziyan in so many cases we have cooperated with the Longpan Municipal Bureau.However, every time Cheng Ziyan appeared as a trace inspector, it was a little surprising that he was selected as a graphic detective professional.However, due to the limited police force, grass-roots trace inspection technicians are usually "panacea". and bear.Since Cheng Ziyan is a trace inspector with a talent for graphic investigation, it is definitely not a bad thing to have an extra "panacea" in our investigation team.

After a while, a thin little girl walked in outside the office door.

The little girl was about the same age as Chen Shiyu, wearing a light blue sportswear and clean jeans, holding her backpack on her chest with both hands, and walked into our office with a blushing face.Cheng Ziyan is not tall, thin, with a standard oval face, red lips and white teeth, fair skin, not too long hair tied into a short high ponytail at the back of his head.In short, Cheng Ziyan, who is not wearing a police uniform, really shines in our eyes.

"Hi everyone." Cheng Ziyan said in a low voice.

"Welcome." I stretched out my right hand and shook Cheng Ziyan lightly.

"There happens to be an empty table here." Dabao was always so attentive.Dabao likes to be lively, and hates to have to keep bringing in newcomers, turning the survey team into a survey office.

"Hey, I was a little surprised by the reaction this time." Master said with a smile.

"That's right, I'm really biased." Chen Shiyu said, still lying on the table reading a book.

I know that when Chen Shiyu first joined the investigation team, I was very resistant, and Chen Shiyu has not forgotten this revenge.

"Didn't you just think it was inconvenient to travel with lesbians at that time?" I said awkwardly, "Now two lesbians can still open a standard room for business trips, so that they don't waste taxpayers' money and improve their work ability. No reason."

"Poor mouth." Chen Shiyu burst out laughing.

"But our shabby survey car only has five seats, and now there are six of us. With Lao Qin's body shape, I don't know if it's crowded in the trunk." Han Liang joked.

"No, no, I'll just sit in the trunk." Cheng Ziyan said in a hurry.It made everyone laugh.

"Xiao Cheng, why don't you be so simple." Lin Tao said, "But you will get used to it soon, we don't have a few truths here."

"That's right, don't believe what a man says." Chen Shiyu was still reading a book.

"This has been considered organizationally." Master said, "Your vehicle fleet has been rearranged, and now you have a new seven-seat SUV. A wagon-like room with the off-road capabilities of a pickup truck]."

After speaking, the master threw a car key on Han Liang's desk.

"Wow, a new car has opened." Han Liang took the key and looked at it, "What brand of car is this? Why haven't I seen it before?"

"You only know BMW and Mercedes-Benz! It's good to have a car, do you still want to choose?" Master gave Han Liang a look and said.

"Is that what Master is here for?" I said, "I thought there was a case, and I was taken aback. It's okay, sister Cheng Ziyan, we will arrange everything for her."

"You should have a treat tonight." Han Liang said to me.

"No, I have an appointment with my son, and I will have dinner with him tonight." I covered my wallet.

"Your son is only three years old!" Dabao protested.

"Who said there is no case?" Master actually took out a folder from nowhere and said, "There was a murder case in Qingxiang this morning, and we reported the information to our provincial department. Although we didn't ask us to rush to help, I think You guys are pretty free recently, so go and make sure there are no flaws in the evidence system."

"Okay! Going out of the survey site, no hemorrhoids!" Dabao jumped three feet high.

"Hey, is it really your own father?" Han Liang said to Chen Shiyu, who was in the co-pilot, while driving, "Is this also called a new car? An old man with [-] kilometers in five years, he will be eliminated as a survey car for us?"

"When did my dad say it's a new car? Think about it yourself." Chen Shiyu said with his head propped up.

"It's good to have a car." I said, "Now that the bus reform is so strict, the bus is supervised by the whole people. If I can change to a seven-seater car, Master must have tried my best."

"I'll buy a seven-seater SUV later on. No one will say I'm using a private car for public use." Han Liang said angrily.

"Your private car can't be modified, so it can't be equipped with survey equipment such as generators and bright lights, so it can't function as a survey vehicle." I said, "But the SUV is very comfortable to sit in and has a good view."

"That's right. It's much better than my TT [Note: TT, a model of Audi]. I'll change it later." Han Liang said.

"Xiao Cheng, I heard that your sister is in some mysterious organization?" Dabao asked, sitting on the back of the middle row, sitting in the last row.

Cheng Ziyan, who was sitting next to Lin Tao, was obviously thinking about something, and was taken aback by Dabao's sudden question, and said, "Ah, oh, yes, Zimo is a policeman in the Night Watch organization."

"Don't ask if you shouldn't ask." I hit Dabao on the head with my backhand and said, "Cheng Ziyan, Cheng Zimo, do you have four children in your family? Are the pens, ink, paper and inkstone all ready?"

Cheng Ziyan covered the corner of his mouth lightly, and said with a shy smile, "Cheng Zizhi, that's so ugly."

"That's right, that's right, what exactly does Tuchen do?" Dabao's curiosity about all unknown things is really unmatched by ordinary people.

"We are mainly doing investigations related to images in some cases." Cheng Ziyan's voice was like a gnat, intermittently amidst the tire noise, "Regarding the research and judgment of surveillance videos, the processing of blurred images, and the comparison of portraits, etc. .”

"Oh, that's very direct and effective." I nodded.

"It's just watching the surveillance? Does it have technical content?" Dabao said.

"Of course." Cheng Ziyan disapproved, and explained seriously, "Even watching surveillance is very technical, and the amount of information obtained by those who can watch and those who can't. Of course, I I’m still a student and I have a lot to learn.”

"Ouch! What a broken car!" Han Liang screamed.

"What's the matter?" I asked in confusion as the survey vehicle driving on the highway didn't brake suddenly or bump.

"Why is there a thorn in the steering wheel of this car?" Han Liang looked at the front and the back of his hand at the same time, and said, "It turns out that the steering wheel has peeled off! What kind of broken car is this?"

"Just go back and install a steering wheel cover, you've been complaining all the way!" I said.

"Can you not complain? My hands are broken!" Han Liang raised his right hand and showed us a superficial skin scratch on the back of his hand.

Lin Tao sat in the middle of the middle row, sandwiched between me and Cheng Ziyan.From the moment he got in the car, he seemed taciturn and very reserved, always trying to lean towards me, as if he was afraid of crowding Cheng Ziyan.

Lin Tao saw that Han Liang was complaining, so he said, "It's a good omen, it's broken, maybe the case will be solved before we arrive at the scene, so we just went on a night tour in Qingxiang."

"If this is the case, then the case is falsely broken." I said with a smile, "In forensic science, the so-called broken refers to the whole layer of skin Tissue connected with deep tissue] separation and rupture, including the rupture of the epidermis and dermis, can be considered a wound. When we do injury identification, we do not look at the total length of the wound, but look at the wound, the whole skin The length of the part where the layer is split and the scar is formed. This is particularly likely to cause dissatisfaction among the appraised, who think that our forensic doctor is fraudulent."

"Old driver, start science popularization if you disagree." Dabao said.

I ignored Dabao, and continued, "The one on the back of Han Liang's hand is obviously not a wound, but a superficial scratch on the skin, which cannot be considered broken."

"Okay, okay, I was wrong." Han Liang waved his hand quickly and said, "Old Qin is developing in the direction of Tang Seng."

When we walked into the office of Chen Detachment of the Criminal Police Detachment of the Qingxiang City Public Security Bureau, Chen Detachment was taken aback.

"Why are you here? Is there any major case?" Team Chen said.

"How could you come to ask us if there is any reason for the case?" I laughed and said, "Isn't it heard that a murder case happened here? We just happened to be idle, so we came to take a look. By the way, why are you doing this?" Are you not in the task force for a while?"

"Oh, you mean the case this morning?" Chen Detachment suddenly relaxed and said, "It seems that our information was reported late, and this case is about to be solved. I have been sitting in the special case team for a day. This is good news just now, so I came down to my office to make a cup of tea."

"Hehehe, did you see that my words have come true." Lin Tao got out of the car and returned to his usual appearance, no longer so stiff.

"Is this...broken?" Dabao looked disappointed.

"That's what happened." Team Chen asked us all to sit down in his small office, and then, while taking out a paper cup to make tea, he told us, "The deceased was a woman in her 40s, and her usual job was riding a bicycle. Solicit passengers in places with no traffic restrictions on the outskirts of the city with electric tricycles."

"Oh, we call it Bengbeng." Chen Shiyu said.

"Our place is called Dayaji," I said.

"It's quite dangerous. That kind of tricycle has caused a lot of accidents, and the fatality rate of passengers is also high." Han Liang said.

Detachment Chen waited quietly for us to finish interjecting, and then said: "This morning, the body of the deceased was found by the riverside of our Qingxiang River, completely naked."

"Sexual assault?" Dabao said, "Such a target, such an assault location, the level of criminals is not high."

"No." Team Chen said, "The suspect is the concubine of the deceased."

"My concubine?" I was a little surprised, "My concubine chose such a place? And... naked?"

"Maybe they want to have a field battle, and then a dispute arises, and they kill people passionately." Chen Detachment said, "There is key physical evidence at the scene."

Cheng Ziyan blushed and lowered her head.

Chen Shiyu was used to the unrestrained speech of these police bosses, so he asked, "What evidence?"

"A disposable wet wipe was extracted at the scene." Detachment Chen said, "Because the wet wipe was very fresh and it was at the scene again, it attracted the attention of our on-site investigation department. When I came back for inspection, it was indeed the key evidence of the case. The wet wipe There was the DNA of the deceased on the towel, and there was also a man's sperm spot. Later, we put the male's DNA into the library for comparison, and we found a man who had been punished for molesting girls, so Curry There is his DNA. Later, we conducted a peripheral investigation and found out that the deceased's private life was very chaotic, and this man was one of her many concubines. With this level of social relationship and the iron evidence of the scene, he can deny it in every possible way. It's no use."

"Has anyone been arrested?" Lin Tao asked.

Detachment Chen nodded and said: "At first we were also worried that the suspect had escaped. However, the good news just came that the suspect has been captured by the investigators ahead and is now in the custody of the criminal police team in the jurisdiction. A surprise trial will start soon. It is estimated that the case-solving information will be released tomorrow morning."

"It seems that our trip was really wasted." Han Liang shrugged and said, "wasting taxpayers' fuel."

"Master said that we are here not only to help solve the case, but also to help review the evidence." I said, "We don't need to solve the case, but we still need to review the evidence! Don't be idle."

"Haha, the evidence is convincing!" Detachment Chen said confidently, "This hard drive contains all the on-site data of the case. It's getting late, so you should go back and rest quickly. After the information on solving the case arrives tomorrow, you can review it slowly." It's not too late for proof."

2.
Springtime for night owls is just that.

After being sleepy all afternoon, I am full of energy.I copied the data from the hard drive into my computer and started to read it slowly.

Lin Tao, who was in the same room, lay on the floor doing planks and sit-ups for a while, and then went to the bathroom mirror to observe his body shape and muscle lines, and then complained bitterly that as he grew older, his vest line had begun to become less obvious.

I turned a blind eye to Lin Tao's troubles and devoted myself to watching the case materials.

The reporter was a dredging worker of the Qingxiang River. During his morning work, when he rowed to a remote part of the Qingxiang River, he noticed something strange on the bank.

The workers stopped the boat and docked, wanting to have a closer look.It didn't matter that it didn't matter, the worker was so frightened that he almost fell off the boat.On the bank about ten meters away from the river, a female corpse was lying prone, completely naked. There was a large pool of blood under the corpse, which had seeped into the soft riverbed soil, so the workers quickly took out their mobile phones to call the police.

Because this is an extremely remote place, the Qingxiang River bypasses a small hill here, and the hill has become a natural barrier for this riverbed, so it is a rare and inaccessible place in Qingxiang City.In addition, the dredging workers found abnormalities on the river surface and then called the police, so no one else arrived at the scene to watch before the police, so there were unique conditions for on-site protection.

The law enforcement recorder of the police officers clearly recorded the whole process of the police [Note: Police, the behavior of dealing with the situation on the spot after the police dispatched].After receiving the call, the two policemen arrived at the scene to check the situation and saw the female body in the distance, so they immediately put up a cordon around the periphery.At this time, the caller was still in the boat on the river. After notifying the technical department to investigate the scene, the police asked the caller to bypass the warning belt and land for questioning.

The tricycle of the deceased was parked on the side of the road one kilometer away from the haystack, and there was no abnormality.

After the technical department arrived at the scene, they opened the investigation channel.The site is soft riverbed soil, which can be said to be an excellent ground for preserving traces and evidence.The trace inspection department extracted the shoe prints of two pairs of shoes and the bare footprint of a person at the scene.After technical processing of these traces in the later stage, it was judged that one of the shoes belonged to the deceased, and this pair of shoes was left near the corpse; the bare footprints were also confirmed to be left by the deceased through texture comparison.Then, the remaining pair of shoe prints were naturally left by criminals.

This is a size 39 skate shoe with some wear and tear.If you can find this pair of shoes, you can even make the same identification [Note: The same identification is a criminal technical appraisal term, which is dedicated to the study of how to use scientific and technological means to determine that the suspected object (person or thing) under review is related to a criminal incident , the scientific theory of whether the object being sought is the same person or the same thing].

Because the photos on the scene were still messy, I couldn't form a complete scene in my brain.But what is clear is that the deceased took off his clothes on a nearby haystack, and then walked to the side barefoot.This process is accompanied by sneakers, and the sneakers are printed on the side of the clothes and there is a phenomenon of circling and pacing.However, for some unknown reason, the barefoot prints and the sneaker prints intersected near the corpse. It should be that the criminals and the victim had disputes and fights here.Then the victim was stabbed and fell to the ground and died. The criminal chose to turn back the same way and left the scene.

On the haystack where the clothes are placed, there is also a wet towel, which is very fresh.The technical department took detailed photos of it [Note: detailed photos, individual close-up photos of individual physical evidence at the scene] and extracted them.It was on this wipe that the technical department extracted the DNA of the deceased and the semen of another man.It is also based on this essence that the criminal suspect Zheng San was locked.

After preliminary investigation, the deceased was named Zhang Lanfen, 45 years old, and an illegal operator of individual tricycles.She has a cowardly husband who usually works on construction sites, and an autistic son.Zhang Lanfen has a rough personality and often bullies her husband.Moreover, she has dozens of concubines outside.Almost anyone she knows, anyone who is interested in her, no matter how old or young, regardless of status, can have an affair with her.

The autopsy of Zhang Lanfen was very simple, because there was no obvious injury on the deceased's body, only a stab wound in the neck, which directly punctured the carotid artery, which can be said to be fatal.This is quite in line with the characteristics of passionate murder.The time of death of the deceased was around eleven o'clock last night, which should be exactly her working hours in the illegal operation.

"Zheng San is a bachelor and lives alone. They usually have sex at Zheng San's house. Why did they choose such a wilderness this time?" I said.

Lin Tao was doing push-ups, and said with difficulty: "Isn't it normal to seek excitement?"

"If it's sex here, why is there no buttocks print at the scene?" I flipped through the photos. Except for the prone position of the corpse, the original condition of the ground could not be determined, and the other parts were just footprints.

"It depends on the posture." Lin Tao said with a smile.

"If you have sex on the haystack, there are too few bare footprints left on the haystack." I said, "If you have sex on the corpse, is it far away from the clothes? It doesn't matter if it is far away from the clothes, the key is Wipes with two people's DNA far away."

"How far is the corpse from the haystack?" Lin Tao asked.

"I don't know, the azimuth map is not well illuminated, so I can't see it." I said.

"Maybe it's very close? Just throw it there." Lin Tao said.

I nodded as if enlightened, and said, "If the shoes worn by the murderer cannot be found, then the DNA evidence is isolated evidence and cannot form a complete chain of evidence."

"Are you frightened by reports of wrongful cases recently?" Lin Tao said, "If the interrogation ends tonight and you have a statement or shoes, it will no longer be an isolated evidence."

I nodded, secretly praying that the case would go well.

"If it was a rape case, didn't the DNA of anyone other than Zheng San be found in the body of the deceased?" Lin Tao added, "And there was no restraint wound on the deceased [Note: restraint wound, left when the victim was controlled by the murderer] Injuries represented by circular subcutaneous hemorrhage at the joints are called restraint injuries] and threat injuries [Note: threat injuries refer to the slight stab wounds, poke wounds, and scratches left by the victim when he was threatened by the murderer. The characteristic injuries represented by such injuries are called coercion injuries].”

"Learning really fast." I smiled, pointed to the computer screen, and said, "Look, this is the original photo of the corpse. What marks are there on her back?"

In the photos at the scene, the deceased was lying prone on the mud floor with his back naked.But at the left shoulder blade on the back, there was a rubbish of blood.

"Blood." Lin Tao said.

"Since it was a one-knife death, the death process will be very fast." I said, "And looking at the traces on the ground at the scene, the deceased did not turn over after lying prone on the ground. The blood should flow into the mud below. How could it be wiped?" Rubbing on the back of the corpse?"

"This is left by the fibers of the clothes." Lin Tao zoomed in on the details of the photo, looked at it and said.

"The deceased was in a low position and was completely naked, and there was no blood on the leftover clothes. Where did the clothes fibers come from? The only possibility is that the murderer's clothes rubbed on it." I said, "But the body is in such a low position, how could it be Get rubbed by clothes?"

"The direction of rubbing is the rule, it should be deliberately done by the murderer." Lin Tao added.

"Why is that?" I asked.

Lin Tao shook his head and said, "Everyone's psychology is different, we can't guess."

"Besides, there are only a dozen or so one-yuan coins in the deceased's purse, and there are no banknotes of large denomination." I said.

"It's normal. How much money can this kind of gangster have?" Lin Tao shrugged. "You see her bank card is still in the bag. There is no conclusive evidence that the murderer has any signs of embezzlement."

What Lin Tao said made sense, but I always felt that there seemed to be a lot of doubts about the evidence in this case, and there were some abnormalities at the scene.But where exactly is the anomaly, I can't tell.I looked at the photos several times, but couldn’t see why. I thought I had to wait for the results of tonight’s interrogation, so I got into bed and forced myself, a night owl, to fall asleep quickly.

Early the next morning, our survey team was assembled and rushed to the task force together.

When Chen Shiyu was on his first business trip, he had a colleague and roommate who seemed to sleep well, while Cheng Ziyan had obvious dark circles under his eyes.At first we thought that Cheng Ziyan was not used to the business trip and couldn't sleep in bed, or that Chen Shiyu's snoring was bothering her.As a result, we were beaten by Chen Shiyu alone, only to find out that Cheng Ziyan copied a lot of surveillance videos around the scene yesterday, and did not sleep until three o'clock in the morning after studying and judging the videos.But she worked so hard, but she didn't get a good return, and the tricycle video about the deceased didn't seem to have much meaning.

After all, the case has key physical evidence, and we don't pay much attention to the video, so we didn't continue to ask Cheng Ziyan what he found, but waited for the good news from the task force.

However, we who entered the special case team were poured cold water from the Chen detachment.

"The sudden interrogation overnight, Zheng San did not explain, and kept calling for grievances. Now the investigators in charge of the interrogation have lost confidence." Detachment Chen said with a serious face.

I know that the investigator's observation and judgment of the interrogated object, which is what we often call intuition, although unreasonable, exists in the subconscious and is scientific.Experienced investigators can almost intuitively judge whether the suspect is the real murderer through the first few rounds of the interrogation.If the investigators lost confidence, it was either that the murderer was too cunning, or that he had caught the wrong person.

"Hey, on the way here, Lao Qin said that this case might be faked." Dabao said, "His crow's mouth is really well-tested and well-deserved!"

I patted Dabao on the back of the head and said to Chen Detachment: "Then what about his peripheral investigation?"

Team Chen added: "Zheng San admitted that he had sex with Zhang Lanfen on the night of the incident, but the place was at his home. The time was about half an hour after dinner, which is around seven o'clock. Moreover, Zheng San started at eight o'clock. I just played mahjong with a few friends for a whole night and didn’t leave.”

"The deceased died at eleven o'clock," I said. "He had no time to commit crimes."

"However, it's hard to say whether Zheng San's poker friends are telling the truth, and whether Zheng San has an offensive and defensive alliance with them." Team Chen said, "We are conducting a peripheral investigation."

"If there is no major breakthrough in the investigation, you will soon let Zheng San go home." I said, "It's not too late, let's go to the scene and have a look."

The many questions that arose from looking at the photos of the scene last night flooded into my mind again at this time.I know there must be something new about this case, but I still can't figure out where the problem is.So, I urged the Chen detachment to hurry up and send a car, took our survey car, and drove all the way to the outskirts of Qingxiang and the hillside by the Qingxiang River.

After all, it is an extremely remote place. Although it has been a day and two nights since the incident happened, the scene is still very well preserved.From a distance, we can see that the police cordon is still intact and swaying in the wind.

We jumped out of the car, walked outside the cordon, and looked in.Sure enough, except for the suspected footprints marked with white chalk, the rest are shoe overprints left by the technical police when they investigated the scene.In this place, even if the police were not sent to guard the scene, there were no troubled people entering.

"This is the haystack where the clothes are placed." Team Chen walked into the cordon after dressing up with us, pointed to a haystack, and said.

I nodded and looked around, nothing unusual.

"The white line over there is where the corpse is." Chen Detachment straightened up and pointed to the river.

I was taken aback, the position of the white line was at least 100 meters away from us.

"That far!" I said.

"Yes." Team Chen didn't know why.

I said, "Why is the corpse so far away from the haystack? The photos don't reflect how far away it is!"

"This, this, is there any problem with this?" Detachment Chen didn't expect my surprise.

"The deceased took off his clothes here, and why did he walk so far away to be killed? Have we thought about this?" I fell into deep thought.

"Then, could it be that they took off their clothes over there, and then the clothes were brought here?" Chen Detachment said.

I shook my head and said, "The barefoot prints start from here and go there, which means that the deceased took off his clothes, socks and shoes at this position."

"Could it be that the deceased just took off his socks and shoes here, and was undressed over there, and then the murderer took the clothes over?" Lin Tao said.

I still shook my head and said, "The socks are on the top of the clothes. This is reflected in the original photos at the scene. It shows that the deceased took off his clothes and pants first, and the socks last."

"Going from here to there naked? What's the intention?" Chen Detachment also asked, "Moreover, she should have taken it off voluntarily, right?"

"Whether it is voluntary or not is our preconceived idea." I said, "There is no basis to say that she took off her clothes voluntarily."

"But there are no restraint injuries or threatening injuries." Lin Tao said.

"If the murderer has a knife, threaten his life." I said, "and the deceased himself was a person with a disorderly lifestyle, so taking off his clothes is not a big deal. Then, naturally, she doesn't need to form restraints and threaten to hurt her." Take off your clothes obediently."

"Could it be raped by others?" Chen Detachment finished speaking, then turned to ask Li Forensic Doctor of Qingxiang Municipal Bureau, "Are there any signs of being sexually assaulted?"

Forensic Li shook his head firmly.

"If it's rape, why not rape here, but run so far?" I said.

"How do you explain the wipes with Zheng San's DNA?" Dabao interjected.

"I know! Framed!" Team Chen patted his thigh.

I smiled slightly, remembering how I was framed [Note: See "No. 11 Fingers" in the third season of the first volume of the "Forensic Qin Ming" series], and said: "If it is a murder, and it is framed on Zheng San If so, firstly, how would he get Zheng San's semen spots? Secondly, he waited until the deceased had finished taking off his clothes before doing it, why did he have to run so far?"

"After all, the deceased took off his clothes and traveled so far to be killed. This is hard to explain." Dabao concluded, "If this point is understood, the case should have progressed."

I didn't say a word, but I already had some confidence in my heart.

I followed the accompanying footprints formed by the murderer and the deceased. Marching], go to the position of the white line.As I walked, I observed the footprints of the two companions.Finally, I found an abnormal scene.

I pointed to the footprints on the ground and said to Lin Tao, "Is the direction of the bare footprints and the shoe prints the same?"

"Yes." Lin Tao said with certainty.

"However, the previous footprints seem to be accompanying, but here, there are overlaps." I said with a smile.

Lin Tao squatted on the ground, looked at it, and said, "That's right, it looks like the print of the sneakers is on top of the bare footprints."

"Explain what?" I asked.

Lin Tao said: "It means that it is not accompanying, but that there is first and last, oh, I understand what you mean."

After all, it is an old partner who can understand my thoughts best. I nodded in satisfaction and continued to move forward.

The footprints of the corpses are a little messy, and the direction and sequence cannot be seen clearly.Then, the board shoe print followed the route alone, and turned back.

The soil beneath the chalk-marked corpse has been stained red with blood, and even large blood clots can be seen left at the scene.

The situation at the scene is complicated but simple, and it is definitely not as simple as it seems, but after all, I have seen the photos all night, and I already know the details of the scene, so I told everyone to leave and go to see the corpse Case.

"He can be released now, Zheng San is innocent." I said to Team Chen.

"Not innocent, he gathered a crowd to gamble and was detained for three days in administrative detention." Chen Detachment said.

I smiled, knowing that Team Chen was worried and didn't dare to release him hastily, so I found a reasonable and legal excuse to detain Zheng San.

"Where's Xiao Cheng?" Dabao looked around, but couldn't find Cheng Ziyan.

"There!" Chen Shiyu still had the best eyes, she pointed to an electric tricycle in the distance.

Cheng Ziyan was squatting beside the electric tricycle, holding a notebook and a tape measure, measuring something.

"We're going for an autopsy, are you there?" We walked to Cheng Ziyan's side, and I asked.

"Oh, this tricycle is actually very characteristic." Cheng Ziyan said in her soft voice, "I'll measure it, and then ask a comrade investigator to drive it under the monitoring head. I have completed the investigation The experiment is also convenient to find the victim's driving track on the night of the crime in many videos."

"Is this okay?" I was a little surprised, thinking that it really is like a mountain across the road.

Cheng Ziyan blushed slightly and nodded.A simple little action, but I can see the strong self-confidence in her heart.

3.
Compared with the situation at the scene, the situation of the corpse is much simpler. There are few injuries in the first place, and after an autopsy, there is not much we can do.

I made a careful study of the only injury on the deceased's body.

This injury was on the right side of the neck of the deceased, and it was a stab wound caused by a single-edged stabbing instrument.The bottom of the wound happened to be the carotid artery, and the sharp needle cut the carotid artery in half.

Because it was a stabbing wound rather than a cutting wound, and the wound was inclined horizontally inward, the blood in the carotid artery was not ejected because it was blocked by the outer soft tissue, which is why there were not many splattered blood spots at the scene.Through this, we can basically be sure that there will not be a lot of blood on the murderer.

I probed along the wound path with a probe, and said: "This wound path is blunt at the top and sharp at the bottom. If you follow the normal knife-holding posture, it should be the hypothenar holding knife [Note: The hypothenar holding knife is Refers to the way of holding a knife with the blade placed below the hypothenar], not the tiger’s mouth grip [Note: The tiger’s mouth grip refers to the way of holding a knife with the blade above the tiger’s mouth] .The hypothenar holds the knife and stabs down with the knife, the creation of the Tao is still horizontal, what does it mean?"

Dabao measured the length of the corpse with a tape measure, and said, "The length of the corpse is 1.6 meters. Since the opening is horizontal, it means that the murderer is not tall. If there is a big difference in height between the murderer and the deceased, the opening should be inclined downward." of."

After speaking, Dabao walked to Chen Shiyu's side, and made a few gestures to her neck.

"What are you doing?" Chen Shiyu gave Dabao a blank look, "I'm 1.6 meters five, okay!"

Dabao said firmly, "Anyway, the murderer is not taller than me."

I nodded, and worked with Dabao to turn the body over to see her back.Although it has been cleaned, the outline of the bloodstain on the left shoulder blade of the corpse seems to be still visible.Unlike looking at photos, when looking at the real thing, you can find that the bloodstains are evenly distributed and the boundaries are neat. It is obviously rubbed on by people on purpose, rather than unintentionally.

I took off my gloves and said, "Although I don't know how to solve the case yet, the top priority is to rush to the task force and reverse the direction of the investigation in time!"

In the task force meeting room, I stood in front of the big screen of the projector.

"Everyone is very clear about the investigation situation in the early stage of the case." I said, "The key point of all the problems now is almost all concentrated on one point, that is, why did the deceased take off his clothes voluntarily or under coercion? Nearly 200 meters before being killed again."

Everyone was nodding desperately, as if they were willing to hear more about it.

"Under the premise of excluding the deceased's mental disorder and running naked late at night." I said, "This should be an act of unloading by the murderer."

The investigators began to talk about it, some denied that the deceased had a mental disorder before his death, and some were discussing what unloading was.

"Let me first talk about the characteristics of the unloading behavior." I said, "There are three main points. First, it must be outside; second, there is a coercive behavior; third, the position of the corpse is far away from the position of the clothes. The first point and The third point is consistent. As for whether there is coercion, I think that since there is a second person present, it is likely to exist. As for why the deceased was not coerced and injured, I have already explained it when I was at the scene, so I won’t repeat it here. gone."

"So what does this behavior indicate?" Detachment Chen asked.

"Most of the purpose of undressing is to control the victim." I said, "In the wild, if you let a person take off naked, then this person will not dare to run away, and secondly, he will be embarrassed to call for help. In addition, keep away from clothing, It can give criminals more criminal space and psychological protection."

"What is a criminal space?" an investigator asked.

"In my opinion, undressing is different from stripping clothes." I said, "The former has nothing to do with sexual crimes, and the psychological motive should be robbery. Just imagine, let the victim stay away from the clothes after stripping. The victim still expects to come back and put on clothes. They will run away and call for help, and secondly, the murderer can easily find the property in the victim’s clothes, which is the so-called more criminal space.”

"This is a very interesting conclusion." Team Chen said, "However, how can you confirm your inference? Is there any basis?"

I nodded, pointing to the photo of footprints taken by Lin Tao on the big screen, and said: "At first, we were all confused by these two accompanying footprints. We simply thought that these footprints should be left by the murderer and the victim walking together In fact, this is not the case. Through this footprint, we can see that the shoe prints are pressed on top of the bare footprints, which means that the bare footprints went over first, and the sneaker prints went past. Since there is a sequence, it means that the sneaker prints The owner of the house should not have moved in the place where the clothes were taken off when he walked over barefoot. So what is he doing? The most likely thing is to search for property."

"What about the wet wipes at the scene?" Team Chen was still not at ease with the inherent evidence.

"We also said that when we were at the scene." I said, "It can be ruled out that Zheng San committed the crime on the spot, and it can also be ruled out that someone deliberately framed Zheng San. Then, the biggest possibility is that the wet wipes were originally kept by Zhang Lanfen. In his own pocket. Let’s not forget that Zhang Lanfen and Zheng San had sex a few hours before the murder. When the murderer was rummaging through Zhang Lanfen’s clothes, he accidentally took the wet wipes out of his pocket. This The action unintentionally misled the police investigation."

"Since this is the case, it just further confirms that this is a case of embezzlement." Dabao nodded.

"At the beginning, I felt that this wet wipe was an isolated evidence and could not explain the abnormal phenomenon at the scene." I said, "Now it seems that all this confirms my idea."

"Now there are no orphan certificates," Lin Tao said.

"It turned out to be a case of robbery and robbery." Chen Detachment was thoughtful.

"Could it be an acquaintance who committed the crime?" an investigator asked.

I shook my head and said, "If the preparation to kill was made in advance, the act of dismounting would be a bit redundant. I think the murderer didn't intend to kill at the beginning. He made the act of dismounting. First, he created robbery for himself. The second reason is that after the robbery is over, the victim will not be able to catch up with him when he comes back and puts on his clothes. However, for unknown reasons, the two had a dispute, and the murderer stabbed the victim to death. Judging from his actions, the murderer does not have the characteristics of premeditated murder, but more like murder with passion."

"The victim is a person who is not afraid of being raped, and he took off his clothes obediently." Chen Detachment said, "So obedient, it is because he sacrificed his color and money to save his life. If this is the case, then what prompted the murderer to kill passionately?"

"It's hard to say, there are many possible factors." I shrugged.

"When the nature of the case is clarified, the direction of our next investigation will be clear. However, there are still very few clues and evidence." Chen detachment said, "Investigate around people who may attack such people. There are many. Moreover, screening without evidence is not easy to investigate."

I nodded and said, "I know. But this case has taken a detour, and the first-hand information is not very complete. I can only say that the murderer should be a young man who is thin and short with low self-confidence."

"Oh? What's the basis for this?" Team Chen said.

I said: "First, all the murderers who take off their clothes have one thing in common, that is, they are not confident. Imagine, if it is a tall and strong man with a knife in his hand, then to control a middle-aged woman, he still needs to use it." Is it such a complicated technique? It is precisely because the murderer is not confident that he chooses the simple and complicated, and uses this method to ensure the success of the crime. Second, the sneaker prints extracted at the scene are 39 yards, and then according to the stab wound on the neck of the deceased According to the direction, it can be judged that the murderer is not tall and will never exceed 1.7 meters. Third, the robbery target chosen by the murderer is actually an illegally operated black tricycle. Such a black tricycle, even if it is very lucky, can earn money if it runs all night. It is less than 100 yuan. Who would take risks for this money? Naturally, those young people with unsound minds. Fourth, at the scene, we can see that there is a rubbish-like bloodstain on the back of the deceased. Although I have I still haven't figured out why there is such a bloodstain, but one thing is certain, this bloodstain must have been deliberately smeared. No matter what the purpose is, this action can reflect the childishness of the murderer."

"Thin young people with the purpose of stealing money." Team Chen said, "That's what we have now."

"No, there are still very distinctive footprints." Lin Tao took out a plaster model and said, "There should not be many such sneakers. By checking the sales channels, the scope of investigation should be narrowed."

"It's not easy." Detachment Chen took the plaster model of the sneaker footprints and said, "There are so many people in Qingxiang and so many shoe stores. If we investigate bit by bit, we don't know when we will be able to solve the case."

"After all, there are not many clues that can be found in the case." I said, "Now that there are so many conditions, it is a blessing in misfortune. I believe that as long as the investigation is careful, something will be found."

Chen Detachment nodded helplessly, ready to deploy tasks.

"I still have something to say."

We followed the sound and saw that Cheng Ziyan was standing at the door of the task force, with flushed cheeks and beads of sweat on his forehead.

Being watched by so many people, Cheng Ziyan was very shy and lowered his eyes.

"Xiao Cheng, it's all right. Did you find anything?" I seemed to have found a life-saving straw, and quickly gave up the podium to Cheng Ziyan.

Cheng Ziyan walked up to the podium with some hesitation, blushed, inserted his USB flash drive into the computer, and started playing a compilation of video clips.

"Leaders." Cheng Ziyan amplified his voice as much as possible, and said, "This is the video of all the electric tricycles in the suburbs near the scene that I sorted out last night."

"All?" I widened my eyes.

Cheng Ziyan nodded and said, "I probably made a video compilation, but there were too many. According to preliminary estimates, at least hundreds of tricycles appeared in the video, so it was meaningless. Later, when I was watching the scene today, I It was found that the electric tricycle of the deceased was quite characteristic. First, the rear wheel hub of the tricycle was very rusted..."

"We don't care about this, let's just focus on the key points." Team Chen was a little impatient.

Interrupted by Chen Detachment, Cheng Ziyan seemed a little flustered, quickly rearranged his thoughts, and said: "In short, I think the tricycle of the deceased is recognizable in the surveillance video. So, I hired an investigator to ride I took the deceased’s tricycle around the outskirts of the city, and then collected images of the tricycle. Through this detection experiment, I can basically pick out which videos belonged to the deceased’s tricycle from the videos made last night.”

"This is already very good." I gave a thumbs up and said, "The reason why tricycles are banned in urban areas is because the number plate management cannot be carried out. Most tricycles are also very similar in shape, so if something goes wrong , It is almost impossible to find it. It is a remarkable achievement to be able to find the tricycle involved out of hundreds of tricycles."

With my encouragement, Cheng Ziyan gained some confidence.Speaking of which, he has a lot of confidence.

She said: "Later, I counted and found that there were 75 videos showing the direction of the tricycle involved, from [-]:[-] p.m. The trajectory of the tricycle involved was drawn."

After speaking, Cheng Ziyan played a map of Beicheng District of Qingxiang City, and then a red line began to run on the map.This should be an electronic trajectory map made by Cheng Ziyan, which clearly reflects the driving path of Zhang Lanfen's tricycle the night before yesterday, which can be said to be clear at a glance.This electronic trajectory map is beautifully made, which we have never seen before, so we were impressed by Cheng Ziyan, and we did not expect that this little girl is really ingenious.

After the red line ran, a complex trajectory was left on the map.Cheng Ziyan pointed to the end of the red line on the map, and said, "This is the last video of the tricycle involved recorded by the surveillance camera at [-]:[-] in the evening. And this direction is exactly the direction towards the scene of the crime. Based on the motive of the crime analyzed by Section Chief Qin, the murderer should have pretended to rent a car, and then carried out the robbery after arriving at a remote location. Then, the passengers sitting on the tricycle at this time are likely to be criminals."

"Are you sure this is the last paragraph?" Detachment Chen asked worriedly.

Cheng Ziyan nodded firmly, and said: "In the area where the crime was committed, there are seven roads back to the city, but only three roads are available for driving. The criminals should not have chosen a road that can be driven back, because these three roads have surveillance cameras. The head also did not record any images of the tricycle involved returning after ten ten minutes past ten."

I secretly sighed in my heart that Cheng Ziyan was so good at knowing the topography of an unfamiliar city so well in a short period of time.This is definitely not only because she is hardworking and down-to-earth, but more importantly, she has an innate advantage in mastering the terrain.

"Then, who is the person sitting in the car?" Team Chen said.

Cheng Ziyan said: "I searched every surveillance head carefully, but I didn't see any video of the suspect getting on the car, which means that there should be no surveillance head at the boarding point. Moreover, the tricycle involved is in the style of a cloak, and the suspect When sitting in the car, the cloak almost completely covered his features. Therefore, the surveillance cameras along the way could not completely record the suspect's physical characteristics and clothing characteristics."

Detachment Chen looked disappointed: "That is to say, I don't even know where to get on the bus."

Cheng Ziyan said: "There is no direct evidence, but I have an inference."

Hearing what she said, everyone cheered up again.

"Let's take a look." Cheng Ziyan played the electronic trajectory map again and said, "The tricycle passed our traffic police, security cameras, and some civilian cameras many times during the period from 49:49 to 49:[-]. It is erratic. I think this should be the track left by her when she was looking for customers again after pulling a group of customers at [-]:[-]. However, after [-]:[-], in the three or four videos that reappeared, the tricycle They are all firmly heading north. Until the last video record at [-]:[-], the direction is all pointing to the scene of the crime, that is, heading north. So I deduce that after [-]:[-], in the North District of Qingxiang City Near the financial and trade market, Zhang Lanfen picked up the criminals and drove north all the way to the crime scene."

"This range is much smaller." Team Chen sat up straight, squinting his eyes to watch the excerpted video on the screen, "Are there many pedestrians near this place? Can you spot any suspicious people?"

"This is very unfortunate." Cheng Ziyan said, "This time period is the time when the night market of the financial and trade market closes, so there are so many people that it is impossible to identify who is suspected."

"It is still difficult to investigate, but the scope is already very small, and we are confident in catching criminals." Chen detachment said.

"I haven't finished yet." Cheng Ziyan saw that Chen Detachment thought she had finished speaking and began to express his opinion, so he opened his mouth and said, "Actually, there are other discoveries."

"What discovery?" Team Chen still looked impatient.

"I took some screenshots from the many video clips just mentioned." Cheng Ziyan began to play some pictures taken from the video surveillance. The picture was very unclear, and only the outline of the tricycle could be seen clearly.

She went on to say: "There is a video, the central connection part between the hood of the tricycle and the driver's seat, there seems to be something extra, you see, this is it."

Cheng Ziyan pointed to a part of the picture.I looked at it for a long time and didn't find anything unusual.It seems that people who often watch surveillance are very sensitive to these details.

Cheng Ziyan then played another picture and said, "This is the picture of the connected part that I processed through blurred image processing technology. The pixels are not enough, but it can be vaguely seen that the extra green thing should be sticking out of the hood."

"The suspect's leg?" Team Chen was still sharp-eyed.

"Yes, I also analyze that the suspect changed his sitting position in the hood and stretched out one leg." Cheng Ziyan said, "If this is the case, he should be wearing a pair of green pants."

"Green pants." Chen Detachment pondered, "Green pants are rare, but based on this investigation, it seems a bit child's play."

"Yeah, I thought so too at first." Cheng Ziyan said, "But just before your meeting, Lao Qin told me that the criminal should be a young man of short stature. And that kind of unloading behavior reminded the criminal It was not carefully planned and premeditated, it should be a temporary act."

"Yes, it should be because I was carrying a knife and I needed money, so I decided to grab one." I added.

"I analyzed the merchants near the financial and trade market, and I think young people stay in that area in the middle of the night." Cheng Ziyan licked his lips and said, "The biggest possibility is in an Internet cafe. Because surfing the Internet exhausted money, so I made a temporary decision." to rob."

"It makes sense, but it's just an inference." Team Chen said.

Cheng Ziyan said: "Indeed, there is no factual basis. But based on this inference, I checked the videos of several Internet cafes. Coincidentally, there happened to be a video of a bar counter of an Internet cafe that recorded a man at 45:[-] the night before yesterday. The image of the checkout while leaving. The man just happened to be wearing a pair of incongruous green pants, and was of a thin build."

"Really?" Detachment Chen was refreshed instantly, "It's no coincidence that a few coincidences come together!"

"How old are you?" I asked eagerly.

"21 years old." Cheng Ziyan said, "Because Internet cafes now use real-name registration systems, so I also obtained this person's identity information."

A mugshot of a person appeared on the screen, with his ID number next to it.

4.
"You are so awesome." Dabao looked at Cheng Ziyan with star eyes.Today, Cheng Ziyan's explanation completely made Dabao a fan.

After giving the specific identity of the suspect, not only Dabao, but almost all the investigating policemen present expressed their admiration, and quickly began to plan the arrest operation.Chen Shiyu voluntarily asked to participate in the arrest operation, while we, the criminal technical police, returned to the hotel and sat in my room to discuss the case.

"Brother Bao, don't look like that, I'm ashamed." Cheng Ziyan covered his mouth and smiled.

"You are exaggerating." Dabao said, "We analyze and analyze, at most we can give an investigation direction, and even better, we can give a description of the suspect. You just give the suspect's ID card The number is too direct and effective!"

"With the development of modern technology, there are indeed more shortcuts to solve crimes." I nodded and said, "These new methods are the nemesis of criminals."

"I didn't expect the so-called picture investigation to be so awesome!" Dabao said, "I was still talking about it before, isn't it just to watch the surveillance? Where is there any technical content? Now it seems that it is really interlaced like a mountain. There are so many ways to watch the surveillance. If you don’t know how to read it, it’s some surveillance; if you know how to watch it, you can find the murderer directly.”

"That's not the case." Cheng Ziyan said, "If it weren't for the analysis and judgment of Lao Qin and you before, if the nature of the case and the individual characteristics of the criminals were not clear, it would be impossible to directly find out the identity of the criminal suspect through surveillance. .”

"Even so, it's amazing, there are so many people there!" Dabao said.

"This is also the reason why Xiao Cheng joined our investigation team. Multi-police cooperation is the most powerful force to solve a case." I said.

"In fact, not every case can play such a big role in graphic investigation." Cheng Ziyan said, "First of all, there must be video conditions. I know that many cases happened in rural areas, or indoors, or nearby surveillance If it's bad, then I don't have the video requirements, so I can only work as a trace inspector. The case of Longpanhu last time was like this."

I nodded, and the appearance of that "ghost ship" appeared in my mind again. come out.

"Moreover, there are many coincidences in this case." Cheng Ziyan said, "Many coincidences created the only point in the end. Not all cases, we have such good luck."

"Coincidence is not bad." Dabao is still star-eyed, "But through careful observation, we can find some clues, that is the cow, after all, criminals can't be leak-proof, and if they are caught, there will naturally be a 'coincidence'. .”

"Now there is another problem." Cheng Ziyan said, "It is easy to arrest people, but it is still more difficult to find evidence. The video clues in this case are actually inferred, and they cannot stand up in court unless they can Find those sneakers."

"Yeah, it's finally back to the issue of evidence." I sighed and said, "Everyone, rest, it's been a busy day. I have already explained to Xiaoyu [Note: Xiaoyu is Chen Shiyu's nickname], after the arrest Immediately search and investigate the suspect's activities in detail in the past two days. Two days have passed, and the suspect has enough time to disguise and deal with the aftermath. Whether we can find evidence or not depends on our luck."

Early the next morning, we couldn't wait to rush to the task force.

The atmosphere of the task force was almost exactly the same as the day before.

The suspect Ruan Bao has been arrested and brought to justice, but this Ruan Bao is a stickler.No matter how hard and soft the investigator is, he just doesn't say a word.

"Now we can't beat him, scold him, be hungry, or sleepy." Chen Shiyu said with a tired face, "We can't do anything about him."

"The only difference from a day ago," Chen Detachment said, "the investigators are still very confident and firmly believe that he is a criminal."

"But judges don't trust intuition," I said, frowning.

"His home has also been searched." Chen Shiyu said, "Nothing was found. This man lives alone and has a few acres of land. He usually does farming at home. During the slack time, he wanders outside every day. He also has a history of theft. His family and dogs It’s like a nest, very messy. We searched carefully, but we didn’t find any green pants or sneakers.”

"Since you have a criminal record, you must know how to destroy evidence." I said, "The problem now is that if you can't find these two key pieces of evidence, it may be difficult to prosecute."

The task force suddenly fell into silence, and everyone was thinking about what to do.

"What has Ruan Bao been doing these two days?" I thought for a while, breaking the silence of the venue.

"He himself doesn't say a word." Chen Shiyu said, "The external investigation is still going on. He has a few acres of land planted with peonies, and now he has no farm work. Every day he either surfs the Internet at an Internet cafe, or drinks and gambles with his friends. "

"Where does he live?" I asked.

Chen Shiyu said: "I live in the north, seven or eight kilometers away from the scene of the crime. He usually strolls to the Internet cafes in the city by himself, and sometimes hitchhikes from fellow villagers into the city."

"Hitchhiking? Did the owners of these hitchhiking cars ask?" I asked.

"Investigating." Chen Shiyu said.

Before the words were finished, an investigator walked into the task force and said: "According to the overall arrangement, I just went to investigate Ruan Bao's whereabouts before he was captured. Yesterday afternoon, Ruan Bao went to the Internet cafe in the city to surf the Internet by himself, and at night At that time, I made an appointment with a man from the same village on the phone, and took his tractor back to the village. Our people were waiting at the door of his house, and we captured him after he returned to the village. That is to say, this fellow villager was Ruan Bao. The last person I had contact with before being captured. According to his statement, Ruan Bao didn’t say anything on the way back to the village. There were no more than five sentences in total. It was probably something like, “What are you eating for dinner?”, “Have you won money recently?” The general feeling is that Ruan Bao seems to have something on his mind. He didn’t meet anyone else, so Ruan Bao called to stop once, saying that he was going to see how the peonies in his peony field were growing, and pee by the way.”

"Peony field?" I had a flash of inspiration, interrupted the investigator, and said, "Go, go to his peony field and take a blood-stained tracking dog with you."

Next to a peony field, we were wearing survey equipment, and Dabao was teasing a police dog.

"Are you sure there is a problem here?" Chen Shiyu asked me.

I shook my head and said, "It's hard to say. But I think, if Ruan Bao is a criminal, at this moment, he wouldn't have the heart to pay attention to how Mudan looks. The biggest possibility is that he buried the evidence in the He came here. He may have a hunch that he will be arrested, so he wants to come here to make sure nothing goes wrong."

"If that's the case, he's really superfluous." Lin Tao said.

"Hey, aren't police dogs all big wolf dogs?" Dabao squatted next to a springer, stroking its long ears with his fingers.

Springer put on a look of disdain and refused to look at Dabao.

"Is such a small dog good? Can you smell where the blood is?" Dabao continued.

Springer still sat obediently beside the trainer, just baring his teeth.

"Come on, put on the shoe covers, don't tease the dog." I said helplessly, "Are you unconvinced? Do you want to compare it with whose nose is better?"

"Search." The trainer ordered, and Springer rushed into the peony field like a wild horse that had run loose.

"It must be thinking that it can finally stay away from this annoying guy." I said with a smile.

The area of ​​a few mu of land can be said to be neither big nor small, and it is unrealistic to search all of them by manpower.Moreover, if there is really no buried evidence here, our behavior of destroying crops will be condemned.

Springer searched for about 10 minutes, sat down beside a peony seedling, and looked at the trainer with his tongue out.

I know, this is the attitude of the bloodstain tracking dog after it finds the bloodstain.

I walked over, and the soil in this place did not have fresh traces of digging, so I was a little confused.

The trainer understood what I meant, and gave the "search" command again.

Springer searched around the area again, and sat down next to the peony seedling.

I looked at Springer suspiciously and said, "Then dig."

Several policemen started digging with shovels, and within a few minutes of digging, a policeman shouted: "There is something!"

I was shocked and ran to the side of the pit.The pit had been dug very deep, about half a meter long, and there really was something in the pit.I put on my gloves and cleaned out the dirt pit.

A beige coat, a pair of green corduroy pants, and a pair of worn white sneakers.

"The case is solved!" I couldn't hide my excitement. "There are shoes that can be used for DNA testing, pants that can be used to verify videos, and clothes that can be used to find blood. This is a complete chain of evidence!"

"You are really good! You can find it buried so deep!" Dabao started to pick up Springer's long ears again.

Springer looked helpless.

When the policeman threw a set of clothes to Ruan Bao, he was surprised at first, then depressed.But what really broke through Ruan Bao's psychological defense was the urgent DNA reports.

With a few acres of peony land, Ruan Bao's annual income is enough for his expenses.However, he has been unlucky lately, losing streak in gambling, and becoming obsessed with a paid online game, which makes him seem a little tight.

Before, he would always sneak around and get some small money to spend, but he always thought of grabbing a big one, which would at least guarantee him a few months of food and clothing.He is considered a half-expert in theft, but he has never tried robbery.That day, while playing the game, Ruan Bao thought that he could find someone to rob to try his hand at.After coming out of the Internet cafe, Ruan Bao picked out the target of the robbery.Originally, he wanted to find a self-employed businessman who had just closed the financial and trade market, but he was weak and short, and even if the opponent was a woman, he was not sure that he could succeed in one hit.After much deliberation, he planned to choose a taxi and go to a remote place before doing it.

At this time, there are very few taxis in Beicheng, Qingxiang City, so there are a lot of black three-wheeled operations.Ruan Bao felt that although these black tricycles had little money, since there were no taxis, it was better to settle for the next best thing.

After choosing and choosing, Ruan Bao chose Zhang Lanfen, a rare female driver.

After negotiating the price, Zhang Lanfen drove Ruan Bao towards the Qingxiang River. Ruan Bao took out a dagger as he passed the remote area at the scene.

In order to better control Zhang Lanfen, Ruan Bao asked Zhang Lanfen to take off her clothes and stay away from him, so as to give him more time to find his belongings.Unexpectedly, this Zhang Lanfen really has no taboos.One does not protect wealth, and the other does not protect color.

Although Ruan Bao only found more than 100 yuan in Zhang Lanfen's clothes, the first robbery went so smoothly, which made Ruan Bao a little excited.

Zhang Lanfen was naked 200 meters away, and Ruan Bao had more time to think about whether there were any mistakes in the process of committing the crime.After all, he is a former criminal who has been cracked down and has some anti-investigation awareness.

After much deliberation, the only thing that might have gone wrong was Zhang Lanfen's push on her back after she took off her clothes.

"Will it leave fingerprints on her body?" Ruan Bao thought childishly.After all, one of the key evidences for his previous conviction for theft was that he left fingerprints at the scene.At this time, Ruan Bao began to regret why he came to rob without sufficient preparation. How good would it be if he wore gloves?

Thinking of this, Ruan Bao walked over to Zhang Lanfen.Zhang Lanfen, who only wanted to survive, thought that Ruan Bao was coming to rob her, so she told Ruan Bao that she could do anything as long as she was kept alive.

How could Ruan Bao have any interest in Zhang Lanfen, so he asked Zhang Lanfen to go to Qingxiang River to wash his body.

Although Ruan Bao was only afraid of leaving any evidence on Zhang Lanfen's body, from Zhang Lanfen's point of view, this Ruan Bao was obviously going to kill her, and the method of killing her was drowning her with water.

So Zhang Lanfen begged Ruan Bao and swore to God that she would not report the crime, while waiting for an opportunity to escape to her clothes.Zhang Lanfen clearly promised that she would do everything, but in the end she was told to go to the river to take a bath and refuse to do anything. Obviously she would call the police, Ruan Bao thought.

The two had a dispute because of this.

In Ruan Bao's view, if Zhang Lanfen ran to the road to ask for help at this time, he would be in great danger.But at this moment, Zhang Lanfen made a gesture of running away.After several times of tearing, Ruan Bao got angry and stabbed Zhang Lanfen.It never occurred to him that a random knife in the dark night directly killed Zhang Lanfen.

He only robbed 100 yuan and committed a murder, which made Ruan Bao regret it unceasingly.But after all things had happened, he began to think about how to escape legal punishment.

There was a lot of blood at the scene, and Ruan Bao was not sure if he had blood on his body.Therefore, the first decision I made after going home and thinking about it was to take off all my coats and shoes, walk to my home field overnight, find a place I thought was hidden, and dig a deep pit to bury the bloody clothes.

In order not to be discovered by the police where the bloody clothes were buried, Ruan Bao carefully disguised the appearance of the soil, at least it seemed impossible to know that the soil here had been dug.After everything was settled, Ruan Bao went home on foot and slept soundly until noon the next day.

In order to find out the news of the case, Ruan Bao spent the past two days going to the Internet cafe to surf the Internet as before.Its main purpose is to learn some news about the case from the mouths of the people.

After all, Beicheng District is not big, so there was such an eye-catching case, word of mouth spread widely.The masses have many speculations about the case; there are also many hearsay and gossip about the handling of the case.

After the police captured Zheng San, Ruan Bao breathed a sigh of relief.Although he didn't know that he found a wet wipe when he was looking for property, which almost misled the investigation, but the police put the suspect on the body of the acquaintance of the deceased, which made Ruan Bao feel relieved.

After getting the news, Ruan Bao didn't go back to the village late at night, but took a ride with fellow villagers and was going home in the evening.He was planning to go home and have a celebration drink with himself.

But he never expected that, for the sake of insurance, he took a second look at the vast land, provided clues to the police, and laid a net for himself.

"Cheng Ziyan made the first contribution in this case." Sitting in the car on the return trip, I gave Cheng Ziyan a big thumbs up.

"No, no, I just do what I should do." Cheng Ziyan's face turned into a red apple.

"This case still reminds us that any isolated evidence is not enough to prove everything." Lin Tao sighed, "The chain of evidence is really a treasure of the rule of law."

"Well, not preconceived, not judging others by oneself," I concluded, "is the essence of realistic reasoning."

"I'll change the car when I get back. It's cool to drive an SUV." Obviously, Han Liang didn't notice our gains, and was already thinking about his next new car.
