Chapter 963 Fly Identification
"Captain Jiang. All the flies are here."
Several technicians from Changyang City Criminal Science Technology Center placed glass bottles one by one on the black leather laboratory table, arranging them more densely and neatly than in a candied fruit shop.
Looking around, you can see that these bottles contain fly eggs, larvae, pupae, and a few even contain adult insects.
Among them, the number of adults is the least, because they run fast. The remaining maggot eggs and pupae are very large.
"It's a considerable number." Jiang Yuan nodded with satisfaction.
Wan Baoming chuckled and said, "Captain Jiang, collect as many insects as possible according to your request."
"Well, you did a good job." Jiang Yuan praised again, even if he had used up all his emotional skills for today, and then said: "We don't have any professional entomology experts in our Criminal Science Center."
Wan Baoming knew that this was a compliment, and hurriedly said, "You know, insect identification and appraisal in our country are usually done by professionals. If we have any needs, we usually ask experts from the Department of Biology of Changyang University for help. Our previous appraisal report was done 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 appraisal report. He determined that he died between 28 and 42 days ago." Jiang Yuan nodded.
The body parts were found 20 days ago. Considering the degree of corruption, the time range of 28 to 42 days is considered a good one.
"Yes." Wan Baoming nodded, then hesitated and asked, "Do you have any questions?"
It is actually a bit radical to say that most of the investigators at the crime scene do not understand entomology. In fact, based on the current situation of the Changyang Municipal Bureau, it is not an exaggeration to say that none of the investigators at the crime scene understand entomology.
This is not something to be ashamed of. Entomology is a specialized subject that requires no less time and effort than botany.
As far as the current academic situation in China is concerned, biology itself is the top subject. Botany and entomology, the traditional biology, can be said to be the least popular of the least popular, the best of the best.
After a PhD student in entomology graduates and gains another three to five years of experience, he or she cannot actually say that he or she has made any achievements in entomology. As for identifying the species of insects... he or she may not be good at it.
For entomology professionals, identifying insect species may be simple, but in fact it is not that simple. Considering the accuracy required by the police, it is even rarer to find entomology graduates who dare to say "I can do it" with confidence.
After all, for most of the problems in this world, if they are vague, there will be a large number of experts who can give a variety of answers, but if there is a true and unique solution, there will be very few people who can give the answer.
But considering the current treatment and needs of the police station, they cannot recruit even the most experienced experts.
Even if a PhD graduate 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 a government agency that grassroots police officers aspire to work in, they are unwilling to go there. If they are willing to go there, wouldn't the employment prospects of taking the civil service exam be better? Why go to the hard-working frontline?
The bottom line for a PhD student in the biology department is to raise mice. Although digging up corpses and graves requires extremely high professional knowledge, it does not require research ability.
Jiang Yuan was only checking the situation of the Changyang Municipal Bureau. After all, it was the criminal science center in the provincial capital. However, it now seemed that although doctoral students were no longer scarce, they were not yet common to this extent.
"The judgment is correct, but the front line cannot operate for such a long time, right?" Jiang Yuan said, and the criminal police officers next to him nodded repeatedly.
Academics are academics, but it is too difficult for frontline police officers to collect evidence within a 14-day period. It is difficult to obtain two weeks of surveillance video, and even more difficult to watch it all. It would be fine if there was one confirmed surveillance video, but it is too easy to miss something when watching dozens or hundreds of surveillance videos during the period of casting a wide net.
"Then... let's look for an entomology expert from somewhere else?" Wan Bao knew that Jiang Yuan understood forensic botany and that he knew quite a few botanists. He guessed that Jiang Yuan wanted to use his personal connections to find some more people to look at the insects.
Of course, there are some expenses involved. Not only do you have to pay for the travel expenses of inviting someone to work for a few days, but you also have to pay for round-trip transportation and accommodation. If it is a big-name expert, you may also have to send someone to accompany him and treat him to a few good meals.
Therefore, the police will not invite experts to help unless it is a major case. Moreover, many experts are actually unwilling to cooperate. At the very least, only police stations of a certain level are eligible to invite them, which is difficult to align with the granularity of front-line criminal police.
Jiang Yuan naturally knew more about the complicated situation. He waved his hand and said, "As for fly identification, I can do it. My original intention was to find a few people who know a little about entomology to help. Forget about inviting them remotely. I can't afford to waste time."
Inviting experts to help also requires them to have a schedule. The more famous the expert is, the less free time they have. Especially for experts from other places, you may have to wait for several days.
Jiang Yuan doesn't have a few days to waste. If he waits a few more days, the corpse will turn into mud.
Furthermore, he has LV6 fly identification, although it is not a full range of insect identification, but referring to the cryptographers who have passed away before, LV5 cryptography is enough to dominate the academic world. As far as this case is concerned, LV6 fly identification is definitely more than enough.
Wan Baoming hesitated for a moment, thought for a moment, and said, "Then I'll ask Professor Li to come over..."
"No need, let's get some help." Jiang Yuan changed into a white coat, rolled up his sleeves and said, "Let's sort the flies in the bottles first. The ones that are not flies in the bottles with adults should be transferred to other bottles first. Put similar flies together."
This is something that any experienced technician can do. Jiang Yuan sat aside, picked up a bottle of mixed larvae nearby, and began to sort them.
Since Jiang Yuan started to move, the technicians at the Criminal Science Center naturally didn't say much.
Wan Baoming also put aside his doubts, rolled up his sleeves, put on gloves, stood beside Jiang Yuan, ready to help, and watched Jiang Yuan line up the maggots one by one.
Wan Baoming began to become confused again: "Do you recognize different species of maggots?"
Jiang Yuan was tickled: "Don't you know him?"
Wan Baoming also laughed: "What do you think of this?"
"It's mainly about counting." Jiang Yuan said as he worked, "For example, this one has 6 pore-like processes on the anterior spiracles, and the long process of the eighth abdominal segment has a single branch at the base. This is the third-instar larva of the summer toilet fly, and this one has 3 pore-like processes on the anterior spiracles... It's the meta-toilet fly..."
Jiang Yuan pulled out a maggot that was covered with hair and had sharp ends, a bit like an elongated croissant, and explained it to Wan Baoming.
Wan Baoming lowered his head silently: "I may not be able to help..."
