Early the next morning, with the help of Director Zhu, he "infiltrated" the ministry and found the opportunity to report on his work one by one. Pen, fun, pavilion www. biquge。 info

The application for the allocation of equipment should be studied and studied, and after the study is completed, it will be decided not to report to the leaders of the department in charge. In short, the leaders of the agency are very busy, and they are even busier at the end of the year, so they will receive the materials first, and then study them when they have time, and let them go back and wait for news.

It is not easy for the leaders of the organs to squeeze out valuable time to listen to the report, and it is not easy to accept the materials, who can have this treatment with so many deputy detachment leaders of the criminal police in the country?

If you want to invite the leader to dinner, the leader may not have time, and he is not qualified to invite someone to dinner. I did everything I had to do, and I asked the director again to buy a ticket and rush back.

"Wife, where are you?"

"In the unit. ”

Although she is no longer the manager of the BJ branch, she still enjoys the treatment of vice president, Li Xiaolei sat in the spacious and bright office, dangling her legs and saying gracefully: "You don't have time, I can't help but go back to my hometown." Yesterday I went to the Silk River and gave the New Year's gift. I didn't stay in the unit hotel at night, and I went back to our house. My sister-in-law cleaned up and lived very comfortably. ”

"The golden nest and the silver nest are not as good as their own grass nest, of course, it is better to live in their own home. I just got off the plane and am on my way to work, will you go back to Nangang today?"

It's okay if you don't come back, but a lot of things when you come back.

As the "young grandmother" of the "carpenter's house", she must fulfill her obligations as a wife and daughter-in-law, Li Xiaolei looked up at the time on the wall clock: "I can't go back today, your third aunt's fiftieth birthday, people have made several phone calls, and I met yesterday and said, I want to go to dinner." ”

"There are a lot of electric cars in my hometown, so be careful on the road. ”

"Don't go back to the Silk River, the third aunt's family just bought a house, and now she lives in the county seat, and she is in a community with Secretary Lu. After eating, stay in the unit hotel, and return to Nangang early tomorrow morning. ”

There are many relatives, and human contacts are naturally indispensable.

My parents, my sister and brother-in-law didn't have time, she became a "family member", and now she is responsible for all these things, and she enjoys it.

"Okay, you look at the arrangement. Han Bo smiled and hung up the phone.

When I went to the Public Security Bureau, the taxi driver couldn't figure out the identity of the passenger and didn't dare to make a blind detour. It's much faster than taking the airport bus and then taking a taxi, and it's time to get off work when I arrive at the technical brigade.

Instructor Wei Shaowen and deputy captain Chen Qiwen were standing at the door talking, and when they saw their boss, they greeted them together: "Team Han, how to take a taxi, give us a call to arrange a car to pick you up at the airport." ”

"Team Han, you came back just in time, Dr. Tian is doing experiments, and we will have dinner together later. ”

The old classmate stayed up until two or three o'clock in the morning yesterday, and continued to be tested early this morning, but the murderer's DNA was still not detected until he got on the plane.

He couldn't make a phone call on the plane, Han Bo was so anxious that he put his suitcase in the corner of the hall and asked eagerly: "Instructor, Chen Da, is there any eyebrow about the murder in Donggang?"

"Check it out, just check it out, Dr. Tian is confirming it. ”

Chen Qiwen accompanied him to the laboratory, and asked excitedly: "The deceased was indeed raped, but the murderer left very little semen. Dr. Tian repeatedly tested and finally extracted it from the sample in the afternoon. ”

"Checked out?"

"Not only the sperm spots, but also the gloves were extracted and compared. The Han team has to be convinced, it is really a trace test. ”

Just check it out, Han Bo let out a sigh of relief. walked into the locker room, picked out a white coat that he should be able to wear, took off his coat and asked, "Is there any result of police dog tracking?"

"No, how could there be. ”

Chen Qiwen looked through the glass at Tian Xuewen, who was concentrating on his work inside, and said with a wry smile: "Zhang Wenbin's police dog is not very reliable, and the wind is too strong, and after more than ten hours, how much smell left by the murderer is also blown away by the wind." Zhang Wenbin ran after him for most of the night, and his leg almost broke off, but he found nothing. ”

He didn't have confidence in the "dogherd", and Han Bo didn't have much confidence either.

The reason why the police dog team was asked to go out to the scene with a smell source was that they wanted to try their luck, and second, they couldn't always stay in the police academy every day.

"Has the Wei detachment returned?"

"No, it's still in the task force of the Donggang County Bureau. ”

The DNA laboratory participated in the actual combat for the first time, and as an instructor, he had to care about the case, Wei Shaowen inquired and introduced: "The task force has not made any progress for the time being, and only clarifies the identities of adults and children." The adult's name is Sun Jingshu, 29 years old, a member of Group 13 of Huaduo Village, Chengdong Town, Donggang County, and works as an accountant in the town's nursing home. The child's name is Liu Shuang, nicknamed Shuangshuang, five years old this year, and he was very cute when he was alive.

Her husband's name is Liu Xiangguo, a salesman of a company in the town, and his business is running very well, and his family conditions are good. The little couple is affectionate and loving, and there is no contradiction. On the afternoon of the day before yesterday, a family of three went to a colleague's house in the town to drink happy wine, and after drinking the happy wine, several colleagues pulled Liu Xiangguo to play mahjong in the unit.

All salesmen, all smoking, smoky miasma, and the child will go to kindergarten the next day, Sun Jingshu took the child home first as usual, but she didn't expect this to be a point of no return. Liu Xiangguo played mahjong until dawn and slept in the unit, and the police of the Donggang County Bureau found him, only to learn that his wife and children were both killed at night. ”

"After participating in other people's happy events, I have to go back to the funeral, which is really happy and sad. ”

"He is also a Madahar, and he actually let his wife take the children back alone at night. But then again, the security in Donggang has always been good, and under normal circumstances, there will be no problems when walking at night. ”

"It's a pity that something is not normal. Han Bo patted his thigh, got up and said, "I'll go in and take a look, don't wait for the two of you, I'll take Dr. Tian out for dinner." ”

"Okay, then let's get off work first. ”

There are three people in the laboratory, Li Jiaqi and Xiao Xu are working as assistants to Tian Xuewen.

The old comrade was too involved and unaware of his arrival, Han Bo didn't want to disturb him, so he and Li Jiaqi nodded slightly, and picked up the atlas.

The most troublesome thing is extraction, Tian Xuewen kept changing the test tubes, until he put all the test tubes into the test plate, and then turned around and noticed the old classmate standing behind him.

"Brother Han, what came back. ”

"Just now. ”

Asked him to help and let him work overtime continuously, Han Bo was very reluctant to go, pointed to the chair in the corner, asked him to rest for a while, and went to work, Mali tapped the keyboard a few times, and turned around and asked: "Why is there so little semen left by the murderer, and he almost failed to detect it." ”

"It's probably too stressful, and it varies from person to person. When a big girl talked about these things in person, Tian Xuewen was a little embarrassed.

Li Jiaqi was indeed embarrassed, and turned her back without saying a word.

Solving the case is important, Han Bo didn't care so much, and muttered: "Why does the murderer want to rape, isn't it just to vent his wild desires and obtain sensual pleasure. He may be nervous, not probably, he will definitely be nervous, but that shouldn't affect ejaculation. The three of you are all medical students, do you think you can deduce the approximate age of the murderer from this?"

Tian Xuewen leaned on the back of his chair and said with a smile: "I am studying medicine, but not forensic medicine, don't ask me such a professional question." ”

There is not much time to get along with the "young marshal", Xiao Xu wanted to leave a good impression on the leader, and blurted out: "Team Han, young people have more semen, and old people have less semen, but I feel that it is impossible for people in their seventies and eighties to do such a thing." And at the same time, a woman in her twenties and a child can not be controlled, and an old man can't do it. ”

"Determined to be a solo offender?"

"Basically, it can be determined. ”

This question can be answered, Li Jiaqi turned around and said: "The scene is full of withered weeds, and the footprints have not been extracted, but the protection is relatively good, and the traces of scuffle can be seen, so it should be a single crime." From the analysis of the gloves left by the murderer, he should have a bicycle or motorcycle like the victim, which may be a tailgating or a coincidence. ”

Riding a bicycle or motorcycle in winter, it is too cold without gloves and your hands will freeze. Therefore, the victim wore gloves until his death, and could not extract the killer's dander from between his fingernails.

DNA testing should not be limited to what to send, but should understand the facts of the case, be familiar with the relevant situation at the scene, reconstruct the necessary on-site process according to the relevant characteristics of the samples, restore the original state of the relevant physical evidence, and envision the parts that may leave DNA, and then extract and test them in a targeted manner.

Otherwise, it is very easy to miss or delay.

Han Bo pondered for a moment, and suddenly said, "Jiaqi, describe the scene to me again." ”

"Team Han, it's not clear to say this, I'll draw you a picture. ”

"Okay. ”

Li Jiaqi took out a pen and paper, introduced while drawing, and had a general understanding of the case and the scene, and the results of the second test also came out, and the gloves were indeed left by the murderer!

Han Bo picked up the gloves containing the evidence bag and looked at them, took out his mobile phone and dialed the number of "Lao Shuai".

"Detachment Wei, I, Han Bo, have just come back and reported an important situation, through the secondary examination of the samples extracted from the victim's body, it can be determined that the gloves found at the scene were left by the murderer. ”

With the killer's DNA evidence in hand, the rest is much easier.

Wei Guoqiang was excited, smiled at Director Zhang Baoli, held his mobile phone tightly and said: "Great, this is good news, it is a breakthrough! Our side is organizing a police investigation, and as soon as the results come out, as long as there is any suspicion, all blood will be drawn and sent over for comparison."

Xiao Han, you have a lot of work to do next, so you and Dr. Tian should hurry up and rest. There are only 5 days left before New Year's Day, and when it comes to this year's homicide detection rate, the Donggang County Bureau is under pressure, and our city bureau is under pressure. Bureau Chen and Bureau Cui asked us to investigate and crack it quickly, and as soon as the inspection materials are delivered, you will not have time to rest if you want to. ”

"The reason why the Wei detachment has not been confirmed until now is mainly because the murderer left very little semen, and the dander on the gloves is also a trace amount of physical evidence, which is more troublesome to extract. ”

Han Bo and Tian Xuewen glanced at each other, and then said, "In comparison, it is much easier to test and compare the suspect's blood, and the efficiency will be much higher. Dr. Tian and I were two people, one day shift and the other night shift, staggered, people stopped the equipment, and made every effort to ensure the handling of the case, and never delayed the investigation of the special case team. ”
