Solving the case: Combining the police dog's olfactory genes at the beginning

Chapter 77: Solve the case within the time limit, and reward the case for solving the case (please collect and ask for monthly tickets, two-in-one)

Later Luo Fei learned that the deceased was named Yang Xiaobing, 13 years old, a first-grade student in the second middle school, and was killed on the way back from evening self-study last night.

Both parents were employees of the silk factory. Because they both worked the night shift last night, they had no idea that their son Yang Xiaobing had not come back all night.

It wasn't until the morning that a familiar villager discovered Yang Xiaobing's body in the vegetable field and immediately notified Yang Xiaobing's parents and the police station.

Other colleagues from the criminal police team also arrived at the crime scene one after another.

It didn't take long for Yang Mei and the others to complete the inspection and investigation of the scene and the body.

"There were two obvious injuries on the deceased's body. One was a dent caused by a heavy blow to the right side of the deceased's head. This was the real cause of the deceased's death. The second injury was that the murderer cut off the deceased's reproductive organs. We also had the same injury at the scene. The deceased’s reproductive organs were not found, and combined with Zheng Bin’s case, we suspect that the deceased’s reproductive organs were cut off by the murderer and then taken away.”

"Also, based on the stains on the body of the deceased, the time of death should be around ten o'clock last night, which is basically consistent with the time when the deceased returned home from evening self-study."

"In addition, we found the deceased's mobile phone and schoolbag on the path next to the vegetable field, and collected two sets of shoe prints, one large and one small, on the ground. We compared the small set of shoe prints and found that they were left by the victim. We suspect that the larger set of shoe prints are those of the murderer, because we also found that set of shoe prints next to the body of the deceased, so the deceased should have been attacked by the murderer there. This is the first case. Discovery site." Yang Mei said and pointed to the path next to the vegetable field on the right.

"Based on the size of the set of shoe prints found at the crime scene and the depth of the shoe prints left in the vegetable field, we speculate that the murderer should be around 175cm tall and weigh around 130 kilograms."

"The weapon used by the murderer to cut off the deceased's reproductive organs was the same as in the Zheng Bin murder case. It should be a sharp instrument with a sharp end, similar to a dagger." Yang Mei continued.

After listening to the autopsy and scene trace investigation results report, combined with the murderer's modus operandi, it can basically be determined that the murderer of Zheng Bin case and Yang Xiaobing case is the same person.

Then everyone discussed and analyzed it for a while.

If before, everyone still suspected that the deceased killed someone because of a vendetta caused by emotional entanglements, then this suspicion is basically gone now, and a 13-year-old child can't talk about any emotional entanglements.

At this time, everyone's speculation is that the murderer is killing for the reproductive organs of the victim. Of course, some people have also raised the possibility that the murderer is killing people continuously. In fact, he is throwing smoke bombs to the police to mislead the police. The target is only one of them, and the next victim may even be the target of the murderer. The murderer uses this method to confuse the audience and cover up his true motive for killing.

The discussion and analysis lasted for almost 10 minutes. Finally, Zhao Donglai made a final summary and made the decision to combine the Zheng Bin case and the Yang Xiaobing case for investigation.

Zhao Donglai then arranged for various groups to conduct investigations in an orderly manner.

One group mainly continued the unfinished investigation tasks before. The case of Yang Xiaobing made everyone more suspicious that the murderer killed for the victim's reproductive organs. In this case, then we should carry out investigation for those who are unable to have children or have physiological problems. Investigation is very necessary.

According to the shoe prints left by the murderer at the scene, the murderer was about 1 meters tall and weighed about 75 kilograms. Based on this clue, Luo Fei and others sifted through the information that had not been completed before.

Luo Fei and the others had twenty pieces of information left before. Except for two pieces from Baihe Township, eighteen pieces were from Tianshi Township. However, after some screening, only the ones that fit the characteristics of the criminal suspect were left. There were five of them, one from Baihe Township and four from Tianshi Township.

Yang Su and the others also screened the remaining information, and only eight of them matched the characteristics of the criminal suspect.

At twelve o'clock in the morning, Luo Fei and the others set out from Ningjiang County. They first went to Baihe Township to investigate the last remaining suspect in Baihe Township. Unfortunately, the suspect was still not the suspect they were looking for.

When the three returned from Baihe Township, they went to Yongqing Village and Haitian Village, Tianshi Township, and found two other villagers who fit the characteristics of the suspects. They were still not suspects. By this time, it was already past [-] p.m. .

Without continuing the investigation, the three of Luo Fei returned to the county town. Instead of returning to the criminal police team, they went home alone. By the time Luo Fei got home, it was already ten o'clock in the evening.

Wu Yan left dinner for Luo Fei. When Luo Fei came home, Wu Yan, Luo Xiaoxiao, and Luo Hao were sitting on the sofa watching TV.

"Xiaoxiao, you go scoop the rice for your brother, and I'll serve it to your brother." Seeing Luo Fei come back, Wu Yan quickly got up from the sofa and ordered Luo Xiaoxiao who was watching with gusto.

"Okay." After hearing Wu Yan's words, Luo Xiaoxiao quickly got off the sofa and trotted to the kitchen to scoop up rice. He was still very diligent.

After a while, the food was served.

While Luo Fei was eating, Wu Yan sat next to Luo Fei and asked curiously: "Xiao Fei, I heard that a child died behind the scenes in No. [-] Middle School today, right?"

"Yes, they are students from No. [-] Middle School." Luo Fei replied. Then Luo Fei looked at Luo Xiaoxiao and Luo Hao, who were watching TV, and warned: "Xiaoxiao, Luo Hao, you two have been up late recently. When studying for self-study, go home quickly and don’t linger outside. When you come back, try to come back with your classmates and don’t be alone.”

"I know, our teacher has told us. Our classmates have been discussing that matter all day today. By the way, haven't you found the murderer yet?" Luo Xiaoxiao lay on the sofa and put his head next to it. Luo Fei asked here.

Luo Fei shook his head.

"I think the murderer should be a psychopathic murderer, otherwise how could he be so perverted as to cut that thing." Luo Xiaoxiao analyzed, by the way, "What kind of person do you think the murderer should be?"

"Okay, watch your TV and don't disturb your brother's eating." Wu Yan glared at Luo Xiaoxiao.

The next morning, as soon as Luo Fei arrived at the office, Yang Su informed him that there would be a meeting at eight o'clock.

At this time of the meeting, Luo Fei estimated that it was probably related to the two cases of Zheng Bin and Yang Xiaojun.

as expected
It turned out that two consecutive murder cases occurred, and the deceased died in a horrific and miserable manner. The news spread quickly. It spread throughout Ningjiang County within a few days, causing panic among many people. Many people began to call. The police asked the police when they would catch the murderer, and some people even called the county party committee office directly.

In this case, the county leaders directly called Wu Cheng, the director of the Public Security Bureau, and asked him to solve the case and catch the murderer within half a month.

Otherwise, if it really causes a large-scale social panic and attracts attention from above, not only the Public Security Bureau will be punished, but it is also very likely that the county leaders will be involved.So no one dares to let down their guard at this time.

Then Wu Cheng called Zhao Donglai and asked the criminal police team to solve the case within half a month. If the case could not be solved within half a month, Zhao Donglai would be asked to sweep the streets.

The superiors attached so much importance to this case that Zhao Donglai naturally wanted to convey the notice from the superiors to the people below in order to put more pressure on the people below.

"Of course, if this case can be solved, the rewards from the county will definitely be very generous, and not only the county will have rewards, but the bureau will also have rewards. Bureau Wu said that he would get a 10 yuan bonus. My It means whichever group can solve this case, the 10 yuan bonus belongs to that group." Zhao Donglai first put pressure on everyone, and then used the bonus to encourage everyone to solve the case. It is obvious that there is too much pressure from above, otherwise Wu Cheng It’s not like I would give out 10 yuan as a bonus.

The charm of money is still very great. When Luo Fei heard that there was a 10 yuan reward for solving this case, Luo Fei clearly felt that the attitude of everyone in the conference room became more positive and enthusiastic.As soon as he returned to the office from the conference room, Wang Lei couldn't wait to urge Luo Fei to investigate the case. He was very active. It was very different from the previous two days. Luo Fei clearly remembered calling Wang Lei to investigate the case a few days ago. Case, this guy is still all kinds of slow.

After packing up their things for a while and saying hello to Yang Su, Luo Fei and the other two drove off to Tian Shixiang again.

There are currently only two objects left to investigate;.

One is Huang Ziqing, a 32-year-old teacher at Dada Village Primary School. He went to the county hospital to see an andrologist for three months because of infertility. The doctor diagnosed two causes. One was that sperm activity was too low, making it impossible to conceive. The second reason is that I am under great psychological pressure. When I have sex with my wife, I always come out before I go in. This is also the reason why the probability of pregnancy is greatly reduced. I was treated in the hospital for half a month, but there was no obvious improvement.

Another one is Ma Kai, a 42-year-old farmer from Qingshan Village. He went to a traditional Chinese medicine hospital to see an andrology department six months ago. The reason was infertility and inability to lift. The symptom was that Ma Kai could not produce an erection, and even taking medicine did not work, resulting in If you cannot have sex with your wife, there is no such thing as pregnancy.

After examination, the doctor could not find the cause. There had never been symptoms like Ma Kai's before. Ma Kai stayed in the hospital for more than two months, but no matter how he treated, it had no effect. Later, Ma Kai and his family felt that there was no effect. I gave up the hope and gave up the treatment.

In the car
"Luo Fei, do you think the murderer will be one of the last two?" Wang Lei asked while looking at the information. In fact, he didn't have much expectations in his heart. After all, he had investigated so many files before and no suspect was found. , now there are only two copies left, and the probability of the murderer being among them is too small.

"I don't know." Luo Fei shook his head. Before seeing anyone, Luo Fei really didn't know whether there would be a murderer among the last two suspects, but it would be best if there was. If not, Luo Fei planned to Directly pulling out the files within the past five years from the hospital, he already knew the approximate height and weight of the murderer, and could conduct further screening. Luo Fei felt that if the murderer really had a physical problem, then he would not be without it. I went to the hospital and saw the men's department.

In almost an hour, Luo Fei and the others arrived at Dada Village, and they went to find Huang Ziqing first.

Luo Fei and the others met Huang Ziqing in school, a dark-skinned, strong and tall man. Just from his appearance, there was no way he could be a man for even a second.

Of course, this is not important. The important thing is that he is not a suspect. This makes Luo Fei a little disappointed. As for Wang Lei and Zhong Jun, they are even more disappointed. The three people who came out of Dada Village and were disappointed did not even Any mood is communicated.

After driving for more than two hours, the three of them arrived at Qingshan Village. The location of Qingshan Village is relatively remote. Qingshan Village is backed by the famous Qingshan Forest, which is also the origin of Qingshan Village.

The village head who went to find him first took the three people to the suspect Ma Kai's house.

As soon as he arrived at the door of Ma Kai's house, Luo Fei frowned. There was a familiar smell in the air, which was very similar to one of the hundreds of smells Luo Fei smelled at the crime scene, but Luo Fei was not sure what the smell was. Is it the smell of the murderer or the smell of something else?

Ma Kai was not at home, so Ma Kai's wife was watching TV at home. A woman of about 40 years old with a charming face and an extremely plump figure was obviously wearing a loose sweater, but because one part of it was extremely large, it looked very tight.

Moreover, although the woman lives in the countryside, her fair skin and fashionable clothes make her look like a city woman, without any of the rustic flavor of a rural woman.

"Daughter-in-law of Ma Kai's family, the police comrades came to find Ma Kai. Where did Ma Kai go?" the village chief asked the woman, looking at her with greed in his eyes.

"Comrade police, what do you want to do with Ma Kai? He went to work in the fields." The woman heard that the police were looking for Ma Kai out of curiosity and a little panicked.

"Where does he work? Let's ask him something." Luo Fei replied, but his eyes were looking at the sofa on the right side of the living room door, because in Luo Fei's eyes, the sofa was filled with black air.

Luo Fei suspected that there was a murder weapon hidden under the sofa.

But don't worry about the murder weapon at this time, the most important thing is to catch Ma Kai and control it.

"He's not far behind the house, digging in the ground. I'll take you there," the woman said.

"Thank you." Luo Fei thanked him.

Then Ma Kai's wife took Luo Fei and others to find Ma Kai from the path behind the house.

In about 10 minutes, the woman led Luo Fei and the others to a piece of land. Behind the land was a vast green mountain forest, but no Ma Kairen was seen.

"Where did this guy Ma Kai go?" The woman frowned as she looked at the hoe thrown on the ground.

Luo Fei looked at the half-dug hoe that was thrown on the ground. He was already sure that Ma Kai saw them when they first entered the village, so Ma Kai ran away.

"Ma Kai has probably run into the Qingshan Forest. Zhong Jun, Wang Lei, you two are here to watch her. Don't let her do anything. I will chase Ma Kai." Luo Fei pointed to the woman next to him, Wang Lei and Zhong The two soldiers said.

Wang Lei and Zhong Jun were asked to watch the woman because they were worried that after the woman knew that the police were here to arrest Ma Kai, she would realize that Ma Kai had committed a crime and would dispose of the murder weapon at home. Of course, the woman knew that the probability of the murder weapon was very low. There is no black energy on the woman's head, which means that the woman is not Ma Kai's accomplice and does not know that Ma Kai killed someone. Otherwise, if she knew about it and did not report it, the woman will definitely have black energy on her head.

"I'll go with you too." Wang Lei said.

"No, you're not familiar with Qingshan Forest. You'll probably get lost if you go in. It's enough for me alone. Ma Kai shouldn't have run far yet. I chased him back quickly." Luo Fei shook his head, then sniffed After noticing the smell of horses in the air, he quickly headed in one direction into the green mountains and forests.

Feeling the scent left by the horse in the air, Luo Fei was as fast as a cheetah, flying through the woods. In less than 15 minutes, Luo Fei saw a figure in the woods in front of him, heading towards Qingshan Forest quickly. Running deep.

It was definitely Ma Kai.

Seeing Ma Kai's figure, Luo Fei's speed increased again.

Ma Kai was running out of breath in front of him. He was digging in the field just now when he saw the village chief and three people walking towards his house. Seeing Luo Fei and the three of them walking, Ma Kai Kai immediately believed that the three people led by the village chief to his house were the police.

So before he had time to think about it, Ma Kai dropped his hoe and ran into the Qingshan Forest. The Qingshan Forest was very big. As long as he ran inside, it would not be easy even for the police to find him.

Just as Ma Kai was running and thinking, he heard movement behind him.

Ma Kai quickly turned around to see what it was, but his eyes were dazzled. The next second, a pair of hands quickly grabbed his arm, and then he flew up.

With a "bang", Ma Kai's whole body was slammed to the ground by Luo Fei using the shoulder shoulder he learned from Old Man Wu, and his head was instantly dizzy.

Then there was a "click" sound, and Ma Kai's hands were twisted up and cuffed.
