"This maggot is not a local species. How do you determine this specifically?" Li Chang asked with a trembling body.
Although his research topic during graduate school was not in forensic entomology, if there is such a good direction and practical projects, it would not be a bad idea to go back and take the doctorate exam to do research in this area.
Jiang Yuan, on the other hand, lacked some academic sensitivity and did not seem to be very interested in academics. He said casually, "The appearance of maggots from different local species is different. You should be able to tell them apart."
"I know that flies have different distribution areas. However, ours are blow flies. There are so many species of blow flies, and their distribution ranges are different. There should be overlaps between them. How did you figure that out... I mean, do you want to look it up in a book for comparison, or do a DNA test? For the sake of accuracy..." Li Chang spoke in a lower and lower voice. The methods he could think of were the most basic ones in the books. When he told Jiang Yuan about it, he felt a little ashamed as a graduate student at Zhejiang University.
Jiang Yuan smiled and said, "If you want to send it for testing later, you can do a DNA test. That way it will be easier to write a report. You don't have to look up books. You can recognize the species of blowflies at a glance. As for the geographical distribution, many books and papers say the same thing."
Li Chang wanted to complain in countless ways, but he couldn't. After hesitating, he decided to ask the most difficult question first: "If we don't look up the geographical distribution in books, I mean, if we don't rely on the ranges given in books and papers, how can we determine the distribution areas of different species of blowflies?"
"It's not that we don't rely on books and papers, but they are only references. The main thing is to look at the condition of the body itself." Jiang Yuan didn't talk about such a grand issue, and directly returned to the front-line work, saying: "Look at the blowflies on this body, there are actually several species. The red-headed blowfly is a low-class species, generally distributed everywhere, and the bright green fly is the same. But here there are black blowflies and scarlet-faced naked golden flies. Although they are also distributed in small quantities locally, you have to look at the period."
"kindness?"
"The larvae of the scarlet-faced golden fly are smaller and there are fewer of them. The second and third instar maggots are obviously thinner. What does this mean? It means that they are not at an advantage in the process of competing for the right to develop on this corpse. The reason is probably that they came too late, or they are not adapted to the environment of the corpse in the early, middle and late stages, or both." Jiang Yuan briefly summarized.
Li Chang couldn't help but turn his head to look at the piles of maggot corpses, but let alone distinguish which one was the Scarlet Naked Golden Fly, he couldn't even tell which maggot was the skinny one.
Taking humans as an example, all three-year-old children are small, but some are small because of their age, some are small because of their breed (genes), and some are small due to malnutrition - when there are few variables, Miao Ruixiang can compare the sizes, but when there are more variables, the question of who is smaller becomes difficult.
In a human environment, this question is usually asked to parents, but for blowflies, it is asked to its parents.
The development speeds of different species of blowflies are slightly different, and the differences in development speeds of different species of flies are even greater.
Li Chang thought from the perspective of a student. Knowing the species of flies, recalling or checking their growth rate is what a normal scholar would do. But seeing the growth rate of flies, you infer their species and even their growth environment. This is too abnormal!
"This...how do you judge it?" Li Chang was looking forward to the moment of "hearing the truth in the morning".
Jiang Yuan cruelly interrupted his fantasy and said, "This topic is too complicated to talk about. Let's start with this as the direction for investigation."
When it comes to submitting the documents for inspection and going to court, Jiang Yuan will naturally need to explain this issue, but that will also need to be in written form. If necessary, he can find someone to write it for him, so there is no need to think about it now.
Jiang Yuan made the final judgment based on LV6 fly identification, and this theoretical basis was not something a rookie like Li Chang could understand.
Jian Louyuan had been unable to get a word in, but now that they had finished talking, he hurriedly asked, "Captain Jiang, where do you think the first scene was?"
"Baijiang Province." Jiang Yuan turned over the maggot corpse on the dissection bed and answered clearly.
Jian Louyuan was stunned and said quickly, "Okay."
He didn't expect it to be so smooth. This was a case of a rotting corpse, how could it be so smooth?
Jian Louyuan walked out of the door while talking on the phone, ran a few dozen meters away, took a deep breath, and felt so comfortable that he felt like he was alive again.
Master Wei was left behind. Before he could react, Jiang Yuan waved his hand and said, "Little Wei, come and wash these clothes."
"These have all become scraps of cloth." Wei Shixun looked worriedly at the textiles stripped from the rotting corpses.
"If you don't know how to wash..." Jiang Yuan looked around and said, "Call Shen Yaowei to teach you."
Miao Ruixiang is going to cook the corpse here, so the one who is more familiar with and good at washing clothes is Shen Yaowei.
After a while, Shen Yaowei walked in with his nose covered.
"Come on. Captain Jiang said to take out these clothes and identify their brands or types..." Master Wei gave a brief explanation.
Shen Yaowei let out a sigh and looked at his clothes soaked in corpse water, his face full of worry.
"This is purely a forensic job," the guard muttered.
"Although Captain Jiang transferred his work to us, his main purpose was to train us," said Shen Yaowei.
"You think it's training?" The guard raised his eyes and said, "Captain Jiang's skills are indeed amazing, but aren't forensic doctors usually responsible for the clothes of corpses?"
"It's the forensic doctors who are doing it now. We are just doing the work for them." Shen Yaowei said, and then said: "Credits don't come for no reason. Opportunities only come to those who are prepared."
Master Wei smiled and said, "The only thing that fell down for no reason was work, there was no merit."
Shen Yaowei smiled contemptuously.
Wei Shijian instantly understood Shen Yaowei's expression, and said more seriously, "Did you lose something recently? A third-class merit."
"I am not talented, but I just won the second-class merit." Shen Yaowei smiled lightly, his voice clear and loud.
The two sides were speaking naturally and casually, and when they got to this point, they both raised their heads naturally.
Shen Yaowei's eyes met Wei Shixun's, and Wei Shixun's pupils met Shen Yaowei's eyes, and both of them looked serious.
"You are worthy of a second-class merit?" The guard looked Shen Yaowei up and down and said, "You are a second-generation police officer, right?"
"If Jiang Yuan says it's worth it, then it's worth it." Shen Yaowei smiled: "Are you a Brahmin from Lanyue City?"
The guard pointed upward and said, "Kshatriya. What did you use to win the second-class merit?"
"Loyalty and hard work." Shen Yaowei answered very piously.
Wei Shijian smiled.
Shen Yaowei looked at Wei Shixun calmly.
Wei Shixun laughed for a long time and asked in surprise: "Really?"
"Okay. It doesn't smell that bad anymore, let's wash it." Shen Yaowei said as he took the brush and began trying to peel the rotten flesh off the clothes.
Wei Shixun stood silently by and watched for a few seconds, then began to brush the belt.
