Chapter 945: Fly Identification

"Team Leader Jiang. All the flies are here."

Several technicians from the Changyang Municipal Criminal Science and Technology Center placed glass bottles on the black leather experimental table, arranged more densely and neatly than in a candied fruit shop.

Looking at it, I saw these bottles, both those containing fly eggs, those containing larvae, those containing pupae, and a few containing adults.

Among them, the number of adults is the smallest, because they run fast. The remaining various types of maggots, eggs, and pupae are all packed very much.

"The quantity is not small." Jiang Yuan nodded with satisfaction.

Wan Wan Baoming laughed twice and said: "Team Leader Jiang, according to your requirements, collect these insects as much as possible."

"En, did a good job." Jiang Yuan praised again, even if he used up today's emotional intelligence, and then said: "Our criminal science center should not have professional entomologists, right."

Wan Wan Baoming knew it was a compliment as soon as he heard it, and hurriedly said: "You know, the identification and identification of insects in our country are generally completed by professional personnel. If we have needs here, we generally find experts from the Biology Department of Changyang University to help. Our previous identification report was made by Li Jiaoshou of the Biology Department of Changyang University. He still has a great reputation and often cooperates with us."

"En, I saw the identification report, he judged that he died 28 to 42 days ago." Jiang Yuan nodded.

The corpse pieces were found 20 days ago. Compared with the degree of corruption, the judgment of 28 to 42 days ago is a relatively good time interval.

"Right." Wan Wan Baoming nodded, then hesitated, and asked: "Do you have questions?"

Most of the case handlers at the scene of the crime do not understand entomology. Saying so is actually a bit radical. In fact, as far as the status quo of the Changyang Municipal Bureau is concerned, it is not an exaggeration to say that the case handlers at the scene of the crime do not understand entomology at all.

This is not a shameful thing. Entomology is a specialized discipline, and the time and energy required are no less than botany.

As far as the current academic status quo in China is concerned, biology itself is the top volume king. Traditional biology such as botany and entomology can be said to be the cold door among the cold doors, the volume king among the volume kings.

A doctoral student in entomology graduated, and then practiced for three or five years, actually dare not say that he has any achievements in entomology. As for identifying the species of insects... actually, he may not be good at it.

For professionals in entomology, identifying the species of insects may be simple, but in reality, it is not that simple. Considering the accuracy required by the police, graduate students in entomology who dare to pat their chests and say "I can do it" are even rarer.

After all, most of the problems in this world, if they are ambiguous, there will be experts with sweat-filled books who can give five-flower eight-door answers, but if there is a true solution and a unique solution, there are very few people who can give answers.

But as far as the treatment and needs of the police station are concerned, even if they are experts at the level of sweat-filled books, they can't recruit them.

Biology doctoral students, even if they are willing to work in the police system, they would rather go to institutions like research institutes. Even if it is a government unit that grassroots police officers yearn for, they are not willing to go. If they are willing to go, isn't the employment prospect of the civil service exam better? Why go to the bitter front line.

The bottom line for biology doctoral students is to raise mice. The work of digging corpses and digging graves, although it also requires extremely high professional knowledge, does not require research ability.

Jiang Yuan just confirmed the status of Changyang Municipal Bureau. After all, it is a criminal science center in the provincial capital, but now it seems that doctoral students are no longer scarce, but they have not been popularized to this extent.

"The judgment is not wrong, but such a long time, the front line can't operate, right." Jiang Yuan said a word, and the criminal investigators who accompanied him nodded repeatedly.

Academic belongs to academic, but the time interval of 14 days before and after makes it too difficult for front-line police officers to collect evidence. Not to mention anything else, it is very difficult to take surveillance videos for two weeks, and it is even more difficult to watch them. If there is a determined surveillance video, it is fine. During the wide-net period, watching dozens or hundreds of surveillance videos is too easy to miss.

"Then... shall we find entomology experts from other places to see?" Wan Wan Baoming knew that Jiang Yuan understood forensic botany, and also knew that he knew many botanists, guessing that Jiang Yuan wanted to find some people to see through personal relationships.

There must be some expenses in this. Not to mention the travel expenses for people to work for a few days, the round-trip transportation and accommodation expenses must be made up. If the expert is a bit big, you have to send someone to accompany, and then treat them to a few good meals.

Therefore, it is not a major case, and the police will not invite experts to help. Furthermore, many experts are actually unwilling to cooperate. At the very least, you must have a certain level of police station to have the qualification to invite, which is difficult to align with front-line criminal investigators.

Jiang Yuan naturally knows the complexity inside, waved his hand, and said: "I can identify fly identification. My original meaning is to find a few people, ready-made ones who understand a little entomology to help, and remote invitations will be forgotten, can't afford the time."

Inviting experts to help also requires people to have a schedule. The more famous the expert, the less free time naturally. Especially experts from other places, it is said that they have to wait for several days.

Jiang Yuan has no time to waste for several days. If he waits for a few more days, the corpse will become mud.

Furthermore, he has LV6 fly identification. Although it is not a full-line insect identification, referring to the cryptographer who died before, LV5 cryptography can walk sideways in the academic world. As far as this case is concerned, LV6 fly identification is absolutely more than enough.

Wan Wan Baoming hesitated slightly, thought about it, and said: "Then I will ask Li Jiaoshou here..."

"No need, just come a few people to help." Jiang Yuan changed into a white coat, rolled up his sleeves on the spot, and said: "Let's classify the flies in the bottle first. In the bottle of adults, those that are not flies, transfer them to other bottles first. Put similar flies together."

This is what relevant technical personnel with slight experience can do. Jiang Yuan sat aside, took a bottle of mixed larvae, and began to classify.

Since Jiang Yuan started to move, the technicians of the criminal science center naturally didn't have much to say.

Wan Wan Baoming also put away his questions, rolled up his sleeves, put on gloves, stood by Jiang Yuan's side, ready to help, and watched Jiang Yuan line up the maggots one by one.

Wan Wan Baoming began to be confused again: "Do you really recognize different varieties of maggots?"

Jiang Yuan was poked at the laughing point: "Don't you recognize it?"

Wan Wan Baoming also laughed: "How to see this?"

"Mainly counting." Jiang Yuan said while doing things: "For example, this one, the anterior spiracle has 6 pore-like protrusions, and the branch of the long protrusion of the eighth abdominal segment at the base is single. This is the 3rd instar larva of the housefly. This anterior spiracle has 9 pore-like protrusions... it is the meta-housefly..."

Jiang Yuan pulled a maggot covered with hair, sharp at both ends, a bit like a lengthened croissant, and explained it to Wan Wan Baoming.

Wan Wan Baoming lowered his head silently: "I may not be able to help..." ===== CHAPTER 946 =====
