civil forensic

The personnel affairs in provincial capitals are much more complicated than in county towns.

Speaking of which, Huang Qiangmin is actually a big shot in Ningtai County.Although there is a mother-in-law at the top and a brother next to him, but no matter in terms of qualifications or job content, he is considered to be the eldest brother in the front row.

Yu Wenshu, the captain of the criminal police detachment, was not so happy.Next to him are the Economic Investigation Detachment, the Public Security Detachment, the Anti-drug Detachment, the Internet Security Detachment, and the Internal Security Detachment, as well as the Traffic Police Detachment and the Special Police Detachment with the largest number of people. In addition, the parallel divisions can still pull out double digits. What kind of legal system? Office, Household Administration Office, Science and Technology Communication Office, etc.

And above him, the number of bosses is several times that of the county bureau.

At the same time, the districts and counties under Changyang City also have their own district bureaus and county bureaus, which may have more authority than Yu Wenshu.

In addition, the big mother-in-law of the provincial department will also show her sense of existence from time to time.

And this is why Yu Wenshu especially needs Jiang Yuan.

In the provincial capital city, the competition is fierce, and it is really not easy to get ahead.Whether Yu Wenshu, the head of the criminal police detachment, did a good job, or a little bit better, it can't be reflected.

However, 4 homicide cases were solved in a row, and the current case is also 100% completed, which can be regarded as a remarkable achievement.

Next year, if this momentum can be maintained, Yu Wenshu feels that his life may be more open.

Jiang Yuan has a rough idea of ​​the complicated situation in some provincial capitals.But he was sold here, so he didn't have to worry about so many personnel relations. The dignified third-level superintendent, speaking of it, had a lower police rank than Wang Chuanxinghe and Tang Jia, so it was good to do things.

"427 Drunken Death Case, the specific case, Wang Chuanxing, show it to everyone on the projector." Jiang Yuan didn't even take out a USB flash drive, so he started giving orders.

Fortunately, Wang Chuanxing really knows how to use these office equipment and software, and immediately connects his computer to the projector in the new office, and then quickly finds out the details of the 427 drunken death case.

During this period, Jiang Yuan was not idle, and said to himself: "The deceased Wang Jun, 41 years old, died on April 4 last year, many days after his death... the file said it was 27 to 8 days, this time is wrong, it should be Only six days at most, probably just over five days.”

"In short, many days after his death, Wang Jun's body was found in a house on the hillside outside the village, and there were signs of being moved. At the same time, the deceased had fecal incontinence, and his vaginal sphincter was loose. *Inner superficial and deep swab anti-human sperm pre-tests were all positive, and the DNA test detected male DNA types other than the deceased himself.”

Jiang Yuan described the general case, Wang Chuanxing's projector was also set up, and more content was displayed on the screen.

Some people were studying and reading by themselves, and some couldn't help discussing it: "Does this mean that this is a rape and murder case?"

"The deceased were all 41 years old, and they were... considered a good middle-aged man, but it wouldn't be enough to cause people to commit crimes. Was the deceased gay?"

"The deceased had a junior high school education and had lived in the countryside all year round. Is it so popular in the countryside now?"

Jiang Yuan waited for everyone to read for a while, discussed for a while, and signaled Wang Chuanxing to turn the page.

When he came to a picture of a dead body, Jiang Yuan said: "The photos here are all very clear, and you can clearly see the 3rd instar larvae of the rotting fly, as well as the larvae and pupae of the maggot fly. Judging by the temperature at the scene and using the stable rotting fly as an indicator species, the death time is more accurate in 5 to 6 days.”

Using forensic entomology to judge the time of death of the corpse is a very useful method in the case of a long time of death.

Moreover, the development of forensic entomology has been sufficient. Not only can the time of death be judged according to the growth and development of necrophagous insects, but it can also progress to the succession of insect communities, the growth and development of individuals, including the seasonal characteristics of insects, and various other biological properties.

Of course, there are many complicated situations here. Just the classification of insects and so on is a specialized knowledge.

"The forensic doctor of the current case judged that it was 8 days. Is there a gap of two days?" Wan Baoming, the deputy director of the criminal center, had to ask for himself.

"It's about 3 days away. The difference is mainly in the time when necrophagic insects arrive at the corpse. The arrival time of the rotting fly will be delayed under the low temperature. In addition, the corpse has been moved, and the corpse at the first scene was covered. Maybe it's bigger." Jiang Yuan roughly explained a few sentences, and then said: "This leads to a problem."

Everyone naturally looked at Jiang Yuan, and no one discussed with Jiang Yuan about the content of forensic entomology. The difficulty of this thing was comparable to that of forensic anthropology, and most of the people present only had superficial understanding of forensic medicine.

Jiang Yuan flipped through the file and said: "The person in charge of the case at that time, based on the time of the victim's death, mainly set the time of the incident before April 4, and focused on the three days of 21, 17, and 18, while Judging by the new time of death, the victim is not dead yet."

"The victim disappeared on April 4. This is also a very important point when determining the time of death." Wan Baoming seemed to be explaining for the previous generation of forensic doctors, but in fact, he was endorsing Jiang Yuan.

The judgment of the victim's death time is more likely to be based on the disappearance, but the judgment is not completely based on the scientific judgment of forensic science.

If you think this way, everyone will be more willing to accept Jiang Yuan.

Jiang Yuan didn't hesitate, and said directly: "I prefer the victim, who died on April 4."

"I disappeared on April 4 and died on April 17. Where did the deceased go during the five days in between?" Wan Baoming scratched his head.

Many detectives present were scratching their heads.

"I think we can look in this direction." Jiang Yuandao: "The deceased must have a place to stay. Moreover, he only brought a small amount of money when he went out. He said he went out to buy cigarettes. If this is the case, someone should bring him If he is gone, there is a high probability that he is an acquaintance."

"The original investigation direction of the task force was strangers committing crimes, similar to forcing a woman to commit murder. These are two ways of thinking." Yu Wenshu frowned, and then let go.

If the investigation direction of the current case task force is indeed wrong, then the probability of this backlog case being detected will be greatly increased.

Jiang Yuan nodded and said, "The original direction of the investigation was to imagine that the deceased was raped and then killed. The crime site is close to the place where the body was dumped. Naturally, the deceased does not need money, accommodation, etc."

"However, if the time of death is changed, the deceased cannot stay outside the village for five days without returning home. The reason for his departure is probably the appearance of an acquaintance."

Everyone listened to Jiang Yuan's words and nodded, feeling a little cheered up.

Acquaintances, at least the number is limited, and if you check the relationship again, you may be able to gain something.

"The deceased didn't leave any accommodation records, so he either lived in an acquaintance's house, or lived in a small hotel. In this regard, I think I can ask people from the security detachment to ask about nearby small hotels." A new expert The police officers in the class actively raised their hands to sign up.

"Yes." Jiang Yuan agreed.

"Since you have left the village, you can check the surveillance records of the period before and after you left. I'll ask the Map Investigation Detachment."

"Can."

"Do we have to re-examine the relationship?"

"Can."

Members of the special class, you just assign tasks by yourself.
