360 chasing the deadly letters

Chapter 44

According to the description of the cleaning staff who reported the case, Zhao Hai drank at booth No. 3 that day.Pi Peng took all the drinks on table No. 3, as well as all the wine bottles piled up in the back alley.Due to the large amount of physical evidence, people from the Trace Inspection Division of the Criminal Investigation Detachment were called in. It took two days to identify all the physical evidence. Unfortunately, no physical evidence containing dichlorvos was found.Pi Peng was as disappointed as the others, but Huang Yiwei thought it was a major discovery if he didn't find it.This only shows that the murderer took away the murder weapon used for poisoning, but how the murder weapon was taken away still needs further investigation.

Huang Yiwei and Peng Ying checked the surveillance video of the bar. There are 12 surveillance cameras in the bar, 1 at the gate, 2 in the porch, 2 at the bar, 5 in the hall, 1 outside the bathroom door and 3 fire exit.According to Peng Ying's current staffing, there are [-] people who can be transferred from the criminal investigation serious crime team, plus the people from economic investigation, each group will see two surveillance probes.

Before the start, Huang Yiwei emphasized: "Everyone look carefully, mainly looking for the traces of people related to the No. The focus is on women, and on this basis, it also takes care of men."

Everyone was a little puzzled, Peng Ying asked: "Why is the focus on women?"

Huang Yiwei said: "Poisoning is common in women or weak men, because they do not have the physical conditions to defeat the victim. They generally avoid direct conflict and kill the victim in unexpected ways. People. This is just common sense, so the possibility of men committing crimes cannot be completely ruled out." This time everyone understood.

黄一为又补充了一句：“受害人死于凌晨0:00左右，根据毒药的起效时间重点要查23:00-00:00之间的录像，当然也要兼顾其他时间的可疑情况。”向大家再次确认后，开始查看录像。

黄一为与彭鹰重点盯着3号卡座对面的摄像头，这个摄像头能够拍到3号卡座的全貌。3号卡座有4个陪酒女，酒店的女老板也在3号卡座坐了一会儿。看了死者死亡前1小时的录像，他们彻底懵了。

There were many people in the bar that day, fish and dragons mixed together, Zhao Hai had contact with too many people in just one hour, and drank with many people.Zhao Hai has two wine hostesses, and Jing Gang and An Zhiyong have one each.The sales staff of the bar came to booth 3 to sell wine, and also drank with Zhao Hai and the others.In addition, all kinds of people have visited Card No. 3, such as the Taiwanese girls who drink wine, the "little bees" who sell small things, the girls who create atmosphere, the champagne babies who sell cocktails, the waiters who serve wine, and the cleaners who collect bottles. seat.They were dazzled, and they didn't find anything.Huang Yiwei was puzzled for a while. Objectively speaking, these people are all suspects, counting nearly 20 people. If they are all investigated, it will be too difficult.It is almost impossible to find out when and by whom the poison was poisoned.

Huang Yiwei discovered that Zhao Hai went to the toilet twice in one hour, and he never left booth 3 other than that.The policeman in charge of checking outside the bathroom door and monitoring the fire exits also confirmed this.After Zhao Hai came out of the toilet for the first time, he returned to booth No. 3. When he went to the toilet for the second time, he drank a bottle of beer and walked towards the passage leading to the bathroom.He didn't take anything when he came out, and didn't return to his seat, and went directly from the door of the fire escape to the outside.

Unfortunately, due to the need to protect the privacy of guests, there is no monitoring in the bathroom and washroom, and there is no monitoring outside the fire exit gate, so it is not clear what happened inside.The deceased got out of the fire exit at 23:52, and there was no picture of him coming in after that.

At 0:11, the cleaner who reported the incident took a black plastic bag and walked out of the fire exit door, apparently to throw garbage.Huang Yiwei and Peng Ying agreed that the cleaning staff probably saw the deceased in the back alley, so they need to find the cleaning staff to confirm.Another thing that is very strange is that Zhao Hai didn't take the beer bottle when he came out for the second time. Judging from the tilt of the bottle when Zhao Hai drank, the bottle of beer should be almost finished, and the bottle is probably left in the bathroom Here, the cleaning staff may have seen or cleaned up.

Huang Yiwei took Pi Peng and Che Xiaodong to find the cleaner Ma Suzhen who reported the case, took her to the scene of the crime, and asked her to identify the details in the surveillance.

Huang Yiwei asked: "When you took out the garbage, did you see anyone outside?"

Ma Suzhen thought about it, and said timidly, "I saw it."

"Who are they? How many are there?" Huang Yiwei asked.

"Two. I didn't see who they were. It was too dark outside. I'm old and my eyesight is bad," she said.

Huang Yiwei was a little disappointed, and asked, "Male? Female? Can you tell?"

She said with certainty: "I heard the words, there should be a man."

Huang Yiwei asked: "Did you hear what they said?"

She thought about it and said: "It should be about money, loans or something. I didn't talk about it later, I probably saw me, so I hurried in. I'm just a worker, and I don't dare to cause trouble."

Huang Yiwei said, "Auntie, think about it carefully. Is there a wine bottle in the trash you picked up?"

She thought for a while: "It seems that there is, and it seems that there is no. I can't remember."

Huang Yiwei felt that the wine bottle should be very conspicuous, and she should have seen it, so he asked, "Why don't you clean up the trash when it's closed?"

She said a little frustrated: "I have been working for two months, and I have to stay up late every day. The work is really tiring. I also want to clean up after work, but a few days ago, a customer complained that the wastebasket in the bathroom was full. I I was scolded by the manager. On that day, another customer complained that the wastebasket was full and no one was taking care of it, so I immediately went to empty it. I was too busy, and I really don’t remember if there is a wine bottle.”

After sending off the cleaner Ma Suzhen, Pi Peng found the bag of garbage that hadn't been thrown away, mainly used toilet paper.He rummaged for a long time, but he couldn't find the wine bottle, feeling a little disappointed.People left their names, and geese left their voices. Except for the autopsy that found dichlorvos, there was no trace of dichlorvos in the physical evidence, nor how the deceased was poisoned. In addition, who was talking to the victim in the back alley? ?Huang Yiwei always felt that something was wrong.

Che Xiaodong has been following Huang Yiwei for a long time, and he knows that he may be thinking about certain points.Che Xiaodong asked: "Boss, did you find anything?"

Huang Yiwei glanced at Che Xiaodong and Pi Peng: "I always feel that this cleaner is acting too normal."

Che Xiaodong said: "Normal doesn't that mean she is telling the truth?"

Pi Peng said: "Not necessarily. In some places, she can't tell clearly. For example, if there are wine bottles in the garbage, she doesn't know."

Che Xiaodong said: "But her reason is very reasonable."

Huang Yiwei said: "Some things are clear and some things are not clear. This is a normal reaction of a person to face cross-examination. If everything is clear, there is suspicion of pre-interrogation. I think she behaved too much. It's normal, what she said may be true. In fact, I think she may have a problem. It's just an intuition without any basis. If what she said is true, it will help us detect it. I'm worried that if it's false, it will Misleading our detection direction. We can't afford to delay, but now we have no choice but to follow her instructions."

Pi Peng was a little embarrassed and asked, "What should I do with the rubbish?"

Huang Yiwei thought for a while and said, "Take it back for testing."

Pi Peng's face turned blue, and Che Xiaodong asked, "Boss, these are toilet papers, why take them back?"

Huang Yiwei looked at these two faces full of doubts: "If there was a wine bottle here, the remaining wine in the bottle might be spilled on the toilet paper. Otherwise—" He stopped here, Glancing at Pipeng, he motioned for him to continue.

Pi Peng thought for a while: "On the contrary, if the garbage bag has not thrown the wine bottle, there will be no wine spilled in it." Huang Yiwei nodded without saying a word.Both Pi Peng and Che Xiaodong understood, they picked up the papers on the ground and put them in bags.

Huang Yiwei arranged for Peng Ying's group to continue searching for suspicious persons in the surveillance around the bar. It was quite difficult. The alley was blocked by big trees on the side of the road, so they could only search from the people passing by. It was very difficult. big.The trace inspection team headed by Pi Peng faced the biggest challenge. A large bag of toilet waste needs to be inspected one by one.They endured the smell of all kinds of human excrement on it, looking for clues.They can't think about those things, they can only focus on finding clues, which is the job of the technical police.After another day of hard work and patience, they finally made a major discovery.

Residues of beer and dichlorvos were found on a few rolls of toilet paper, and the case took a major turn.This shows that there was once a bottle of poisoned beer in the garbage bag, and the deceased probably died after drinking beer containing dichlorvos.Huang Yiwei came to the bathroom at the scene of the crime again.There are four toilet seats and four urine seats in the men's bathroom, and the washroom is outside.The bathroom had been cleaned when the crime was reported, and there was no trace of it. However, the deceased could not hold the wine bottle when going to the bathroom. He might put the beer bottle on the sink. The murderer might use this opportunity to poison.Judging from the video footage of the time when the deceased entered and exited the bathroom, the person who poisoned was most likely the person who went to the bathroom or the cleaning staff.

In addition, who took the poisoned wine bottle and how was it taken away?The cleaning staff put the garbage in the bathroom into a large garbage bag and took it to the back alley.Even if the murderer took the wine bottle directly from the garbage bag outside the bar, the suspicion of the cleaning staff still cannot be completely ruled out.The problem is that if the person who spoke to Zhao Hai as the cleaner said is the murderer, the murderer took the bottle, but how can the murderer be sure that the deceased will drink the bottle of wine, and the bottle must be in the garbage bag.

Pi Peng seemed to understand something: "What the boss means is that it is difficult for one person to poison and remove the bottle."

Peng Ying was thoughtful, and said casually: "If there are two people, it will make sense." Some people objected to Peng Ying's statement, and everyone argued.

Huang Yi had a sudden inspiration and asked, "Intel, what did you just say?"

Peng Ying was called suddenly: "I said that two people can make sense."

"Two people." Huang Yiwei repeated, "Two people, one poisoned and the other took the bottle, so the explanation can be explained."

Che Xiaodong said: "Two people. Which two people are it is more difficult. There are too many people in the bathroom in the video."

Huang Yiwei said: "I'm afraid there are not many people who know that there are wine bottles in the garbage bags."

Pi Peng asked: "You mean Auntie Cleaning?" Huang Yiwei nodded.

Peng Ying said: "Auntie Cleaning is suspected, and other people who have been in and out of the toilet during the time of the incident are also suspected."

"Let's rule it out one by one. Let's start with Auntie Cleaning. Intel, check Ma Suzhen's information immediately. If necessary, bring her back for questioning. We still can't rule out the possibility of one person committing the crime. If it is really one person committing the crime, we Something must have been overlooked." Huang Yiwei said to Peng Ying.

After searching for almost a week, Li Jianqiang and Tan Hailong still couldn't find Jing Gang, and they were somewhat frustrated.Strange to say, this guy disappeared like a ghost.Team Yan took Xiao Jing to search all the stores and agricultural cooperatives that sell pesticides, but found nothing.

Duan Yungui from the economic investigation once again had the opportunity to satirize Captain Yan. He learned from Xiang Ming, the captain of the Nancheng Criminal Police Brigade, that there used to be a famous gangster in Nancheng, nicknamed Fire Bird, whose real name was Yang Qianyu.Yang Qianyu's nickname has the character "Huo", which is probably the brother Huo in Zhao Hai's phone.

This time, according to Xiang's team's reminder, he found a gangster whom Xiang's team had caught many years ago, and finally found out about Yang Qianyu.Yang Qianyu's nickname has not been called out for a long time, and now many punks don't know this nickname anymore.The name of Yang Qianyu's company is Yi Xiaodai. It has a fixed office space, a legal business license, and various departments and staff. Everyone is dressed in professional attire and looks very formal. No violations have been found so far.During the first screening, Duan Yungui found this company, but the legal person of the company is not Yang Qianyu, and Yang Qianyu was not involved in the registration information, so it was missed.

The suspicious thing is that there seems to be no profit on the books of Yixiaodai in the past few years, but the boss is neither in a hurry to expand the scope of business, nor to lay off staff.Based on past experience in solving cases, Duan Yungui believed that Yi Xiaodai must have other shady revenue channels, otherwise it would be unsustainable. Moreover, the nickname of the boss Yang Qianyu is Huo Niao, and there is a word "Huo" in it, which is probably Brother Huo.At present, this is only speculation, there is no conclusive evidence.

Duan Yungui also interviewed all the victims in Zhao Hai's mobile phone. They all had borrowed money from Yixiaodai, but were rejected because they did not have suitable collateral.However, they were disappointed, and when they came out of Yi Xiaodai's office, they met Zhao Hai who took the initiative to strike up a conversation.After Zhao Hai repeatedly worked, and he was short of money and had no collateral, he finally made a naked loan.Duan Yungui asked Yang Qianyu, the boss of Yixiaodai, and Yang Qianyu admitted that there were some people doing illegal loan business at the door of the company, but they didn't affect him, so he couldn't manage it.

Duan Yungui is dubious, and has not yet found the connection between the two.All the victims are in the process of repayment, and the nude photos have not been released yet, so the motive for the murder is not sufficient.Duan Yungui spent a few days to find out whether the victim's family members knew about the naked loan, and also confirmed the victim's location at the time when the crime happened, and finally ruled out all suspects.

However, Duan Yungui has gained something after all, and once again ridiculed Yan Dui for his lack of brains.Captain Yan retorted, but sometimes he had to admit that he really didn't find any clues.

According to Huang Yiwei's arrangement, Peng Ying found Ma Suzhen's household registration information, and she turned out to be from the Miao nationality.The police questioned Ma Suzhen again and searched her home.At her home, the police found a pair of old cloth shoes with thousand-ply soles, which were exactly the same size as the footprints found at the scene of the crime, and the focus was similar.

She was very sad, felt very wronged, and has been refusing to admit that she killed Zhao Hai, let alone admitting that she had accomplices.Ma Suzhen has both the time and the convenience to commit crimes.She couldn't justify herself, but the police did not find dichlorvos or a poisoned bottle, nor did they find her motive for committing the crime. After 24 hours, Huang Yiwei had to let her back home, but sent someone to keep an eye on her.

Huang Yiwei doubted his previous thoughts, whether it was two other people who poisoned and took away the bottle, or simply one person.For this reason, he criticized Jiang Ju for his reckless decision.Jiang Ju warned him to be careful in the future, and he also made a promise.Knowing that the director intended to train him, Huang Yi secretly made up his mind to solve the case because he didn't want to disappoint the director's kindness.

Huang Yiwei gathered Team Yan, Duan Yungui and the backbone of each team together, and checked the surveillance video of the bar again.He carefully recalled the logic of poisoning and taking the bottle, and determined that the most likely place of poisoning was in the bathroom, because the deceased took a bottle of beer to the bathroom.If it was in the hall, the poison in the beer bottle could have killed other people, but so far, no other people have been found poisoned.He suggested starting with the investigation of the people who entered and exited the bathroom during the time of the incident, firstly to find out their whereabouts and actions after they came out of the bathroom, and secondly to check whether the people who passed the back alley had contact with the people who had been in and out of the bathroom.

While checking the surveillance video, the special case team received another murder case. The deceased was probably Jing Gang, whom Li Jianqiang and Tan Hailong had never found.The task force was divided into two groups. Duan Yungui and Peng Ying stayed behind to continue searching and monitoring, while Huang Yiwei and Team Yan led people to investigate Jing Gang's death scene.

The scene of the crime was a single apartment, with one bedroom, one living room, one kitchen and one bathroom.The property manager is the person who made the report. Other residents on the sixth floor reported that room 603 emits a foul smell.The property manager brought the spare key of the management office, opened the door and found a dead person, so he called 110.After receiving the police, the Criminal Police Brigade of the Nancheng Sub-bureau dispatched the police, and Captain Xiang Ming led a preliminary investigation of the scene, and found an ID card in the pocket of the deceased, which turned out to be Jing Gang.Team Xiang called Team Yan, and the on-site investigation and the entire case were handed over to the special case team.

The deceased was lying on his back on the bed, his upper body was naked and his belt was loosened.The corpse was highly decomposed, and the corpse exuded a stench, with a relatively strong garlic smell, which was probably caused by dichlorvos poisoning.The remaining skin is purple-black, and the nails are bruised.The eyeballs are cloudy and have been exposed outside the eye sockets.At present, spring and summer alternate, the room temperature is about 20°C, the skin has begun to rot, and the remaining skin is covered with blisters, some of which have ruptured, exuded body fluids, and most of the hair has fallen off. It is estimated that he has died for 5-7 days.Green plaques were deposited on the back of the body and there were numerous maggots around the body.The police officers at the survey site were under a huge challenge. Unsurprisingly, Xiao Jing vomited, but she couldn't bear it until she found a plastic bag and vomited in the bag.Don't blame her, she's an intern, good enough.

The scene had been cleaned up without leaving any fingerprints or footprints, not even the toothbrush and toothpaste in the bathroom.Dai Jiaxing found a body hair on the belt buckle of the deceased. Cheng Liya speculated that this body hair might not belong to the deceased, but probably belonged to the murderer.The reason was that the pants of the deceased had not been completely taken off, and there was no body hair on the abdomen of the deceased.Seeing the disheveled appearance of the deceased and the loosening of the belt, it can be deduced that the deceased may have been with a woman before his death.

The mobile phone of the deceased was found at the scene. One of the contact numbers on the mobile phone had also appeared in the Zhao Hai case.There are also some nude photos of girls holding their ID cards in the hidden photo album of the phone, and there are still communication records of reminders in WeChat. From this, it seems that both Jing Gang and Zhao Hai are the ones doing naked loans, and the online may be Firebird.This is a major discovery, which confirms that Duan Yungui's investigation is in the right direction.Since the mobile phone card is purchased online, the user name cannot be queried, and there is still no strong evidence to directly determine that Firebird is the backstage boss.

A needle tube was found under the cloth wardrobe, with some liquid remaining in it, and blood and fingerprints remaining on the outside of the needle tube.Copied the surveillance video within 7 days before and after the time of the incident, and asked the video team to find clues.

The registration records of the property management office show that the person who rented this apartment is a woman, and the lease period is three months, and more than a month has passed.The name shown on the copy of the ID card is Pang Chunyan, and the place of household registration is Nanjiang Province.After verification, the ID card information is false, and the only truth is the photo.Cheng Liya always felt that she seemed to have seen the person in the photo there. After thinking for a long time, she finally remembered that this woman was very similar to Liang Yushi's sister Liang Yuhan.She met Liang Yuhan when Liang Yuhan came to take away Liang Yushi's body.Cheng Liya told Huang Yiwei her thoughts, and Huang Yiwei was overjoyed.He exchanged views with Team Yan, and Team Yan immediately contacted the public security department where Liang Yuhan's registered permanent residence was located, asking them to check Liang Yuhan's whereabouts.
