Several technicians from the Changyang Criminal Science Technology Center placed glass bottles one after another on the black leather experimental table. The arrangement was denser and neater than that of a Honey Hungry store.
Looking around, we can see that some of these bottles contain fly eggs, larvae, and a few of them contain adult flies.
Among them, the number of adults is the smallest because they run fast. The remaining maggot eggs and pupae are packed with a lot of them.
"A lot." Jiang Yuan nodded with satisfaction.
Wan Baoming chuckled twice and said: "Captain Jiang, according to your request, collect as many of these insects as possible."
"Well, you did a good job." Jiang Yuan praised again, even if he had used up all his emotional intelligence today, he continued: "Our Criminal Science Center should not have professional entomology experts."
Wanbaoming knew as soon as he heard this that this was a compliment. After finishing his words, he hurriedly said: "You know, our domestic insect identification and monitoring,
It is usually done by professionals. If we have needs here, we usually ask experts from the Department of Biology of Changyang University for help.
Our previous supervision report was made by Professor Li from the Department of Biology of Changyang University. He is quite famous and often cooperates with us.
"Well, I have seen the prison report. It is judged that he died 28 to 42 days ago." Jiang Yuan nodded.
The body parts were discovered 20 days ago. Compared to this level of corruption, judging from 28 to 42 days ago is a relatively good time range.
"Yes." Wan Baoming nodded, then hesitated a little and asked, "Do you have any questions?"
Most of the investigators at the crime scene do not understand entomology. It is actually a bit radical to say that. In fact, as far as the current situation of the Changyang City Bureau is concerned, none of the investigators at the crime scene understand entomology.
It’s not an exaggeration either.
This is nothing to be ashamed of. Entomology is a specialized subject that requires only a little more time and energy than botany.
As far as the current academic situation in China is concerned, biology itself is the top-ranked subject. Biology in the traditional sense, botany and entomology, can be said to be the least popular among the least popular, and the best among the best papers.
A doctoral student in entomology has graduated and has practiced for three to five years. In fact, he dare not say that he has made any achievements in entomology. As for determining the species of insects, he may not be good at it.
For entomology professionals, determining the species of insects may be simple, but in fact it is not that simple. Considering the accuracy required by the police, entomology graduates who dare to pat their chests and say "can do it" will
Even rarer.
After all, if most of the problems in this world are vague, there will be a lot of experts who can give a variety of answers, but if there is a true solution and a unique solution, there will be fewer people who can give the answer.
There is less of it.
But considering the current salary and needs of the police station, they cannot recruit even a ton of experts.
Even if a doctor who graduated from the Department of Biology is willing to work in the police system, he would rather go to an institution like a research institute. Even if it is an agency unit that grassroots police officers aspire to, they are not willing to go. If they are willing to take the public examination, their employment prospects will be Wouldn't it be better? Why go to the front line of suffering?
The bottom line for doctoral students in the Department of Biology is to raise rats. Although the work of digging up corpses and digging graves also requires extremely high professional knowledge, it does not require research ability.
Jiang Yuan just confirmed the situation of the Changyang Municipal Bureau. After all, it is the criminal center in the provincial capital. However, it seems that although doctoral students are no longer scarce, they have not yet reached this level of popularity.
"The judgment is correct, but for such a long time, the front line can't operate, right." Jiang Yuan said one sentence, and the detectives who were accompanying him nodded repeatedly.
Academics are academics, but within the 14-day time period, it is too difficult for frontline police officers to collect evidence. Among other things, it is difficult to obtain two weeks of surveillance videos, and it is even harder to watch them. If there is a definite surveillance Forget about videos. During the period of casting a wide net, watching dozens or hundreds of surveillance videos, it’s too easy to miss something.
"Then - let's look for entomology experts from other places?" Wan Baoming knew that Jiang Yuan knew forensic botany and knew that he knew many botanists. He guessed that Jiang Yuan wanted to Through personal connections, find some people to look at insects.
Naturally, there are some expenses involved. Not to mention the travel expenses for inviting people to work for a few days, the round-trip transportation and accommodation expenses must always be made up. If you are a big-name expert, you may have to send someone to accompany you and invite you to eat a few meals. Well done.
Therefore, if it is not a major case, the police will not easily invite experts to help. Furthermore, many experts are actually unwilling to cooperate. At the very least, they must have a certain level of police station to be qualified to invite, which is different from the front-line For criminal police, it is difficult to align the granularity.
Jiang Yuan naturally knew more about the complex situation inside. He waved his hand and said: "As for the identification of flies, I can do it. What I originally meant was that I could find a few people with some knowledge of entomology to help. , just invite it remotely, we can’t afford to waste time.”
Inviting experts to help also requires their availability. The more famous an expert is, the less free time he or she has. Especially experts from other places, who may have to wait for several days.
Jiang Yuan didn't have a few days to waste. If he waited a few more days, the body would turn into mud.
Furthermore, he has LV6's identification of flies. Although it is not the identification of all insects, but with reference to the cryptographers who died before, LV5's cryptography can go sideways in the academic world. As far as this case is concerned, LV6's The monitoring of flies is definitely more than enough.
Wanbaoming hesitated a little, thought for a while, and said: "Then I'll ask Professor Li again -
"No need, here are a few people to help." Jiang Yuan changed into a white coat, rolled up his sleeves on the spot, and said: "Let's sort out the flies in the bottle first. The adult worms in the bottle are not flies. Transfer it to another bottle. Put the similar ones together."
This can be done by relevant technicians with a little experience. Jiang Yuan sat aside and took out a nearby bottle with mixed larvae.
Start sorting.
Now that Jiang Yuan started to move, the technicians at the Criminal Investigation Center naturally didn't say much.
Wan Baoming also put away his questions, rolled up his sleeves, put on gloves, stood next to Jiang Yuan, prepared to help, and watched Jiang Yuan line up the sisters one by one.
Wan Baoming began to become confused again: "Do you recognize different types of maggots?"
Jiang Yuan was laughed at: "Don't you recognize me?"
Wan Baoming also laughed: "What do you think?"
"The main thing is counting." Jiang Yuan said while doing things: "For example, you have this one. There are 6 hole-like processes in the front valve, and the long process of the eighth abdominal segment has a single branch at the base. This is the 3rd instar of the summer toilet fly. The larvae, the one with 9 hole-like protrusions on the front valve ----- is the Yuantu fly
Jiang Yuan pulled a maggot that was covered with fur and had sharp ends, a bit like an elongated version of a croissant, and explained it to Wan Baoming.
Wan Baoming lowered his head silently: "I may not be able to help..."
