Chapter 387: Call him

"Good guy, you came here pretty quickly. We used to come to your door." Shen Yaowei waited for Jiang Yuan to hang up the phone and whistled.

Tang Jia glanced at him and said, "People heard about our Lu Yang case and took the initiative to come to the door. This is considered a positive attitude. Don't offend people."

"Don't just raise an army to investigate the crime." Shen Yaowei smiled.

When he said this, Liu Jinghui and others became more serious.

"Lu Yang has been working on this case for a long time, but it's probably a good thing that no one will help solve the case. We can't just rely on it all the time. They will be the unlucky ones then." Liu Jinghui had nothing to say. The newly appointed Director Chai Tong was not in charge of criminal investigation during his tenure in Luyang. Now that he has chosen Jiang Yuan to handle Luyang's case, there may be some strategy behind it.

"Let's go meet." Jiang Yuan stood up and went out. Huang Qiangmin's office.

Two criminal police officers from Luyang City were sitting at attention.

When Jiang Yuan entered, he could feel the lower air pressure.

"Jiang Yuan, this is Zhou Yuanqiang, the political commissar of the Luyang City Criminal Police Detachment, and this is the squadron leader Qu Hao. He would like to discuss the 805 case with us." Huang Qiangmin said with a smile.

"Isn't it Director Chai who contacted him?" Jiang Yuan pointed out Chai Tong directly.

"Bureau Chai was talking to our director, so we came over quickly. I've heard the name of forensic doctor Jiang Yuanjiang many times this year. I wonder what the regulations are here?" Zhou Yuanqiang was obviously a little unconvinced. Of course, it’s not surprising that police officers, like soldiers, have the aura of being the best in the world.

Jiang Yuan glanced at Huang Qiangmin and Huang Qiangmin told him with his eyes that this wave was sold by Director Chai. Jiang Yuan expressed his knowledge with his eyes.

Turning his head, Jiang Yuan looked at the two Luyang City criminal police officers again. Both of them were a little impatient and said, "Why don't I talk about our current progress first?"

"Okay." It was obviously impossible for Zhou Yuanqiang to refuse the news. For the current Luyang City Criminal Police Detachment, Case 805 has long been a worry. Over the past few years, they have to spend several months on this case every year, and the more they devote, the more they will pay attention to this case. sensitive.

Jiang Yuan vaguely sensed their urgent mood, and did not sell anything, saying: "First of all, based on the photos in the file, I redid the identification of the time of death of corpse No. 1, the deceased Li Yuan. I think The time of death should be delayed by two months, which is four months before the body is found, instead of half a year."

"You can tell by looking at the photos?" Zhou Yuanqiang couldn't help but retort after hearing this, and said: "Even if Dr. Jiang is famous, this is too arbitrary."

"Political Commissar Zhou, you are not a professional. Why don't you call your forensic doctor and let me talk to him? We are also discussing with each other." Jiang Yuan was not angry with this position. As he said, Zhou Yuanqiang is neither a forensic doctor nor a forensic doctor. As he is not a criminal technician, there is no point in arguing with him.

As for the forensic doctors in Luyang City, Jiang Yuan actually had a vague impression that there were multiple WeChat groups of technicians in Shannan Province. Everyone occasionally exchanged some information and asked each other about some technical difficulties, so they became more or less familiar.

Zhou Yuanqiang was a little suffocated and looked at Huang Qiangmin beside him, with a smile on his face, so he lowered his head and dialed the phone. The call is connected.

Zhou Yuanqiang said angrily: "Mei Forensic Doctor, I am Zhou Yuanqiang. Yes, I have arrived in Ningtai County. The forensic doctor here thinks that Li Yuan's death time was inappropriate. Can you talk to him?"

"Isn't the time of death wrong?" Forensic Doctor Mei on the other end of the phone muttered, his smile instantly frozen, and he hurriedly asked: "Who are you talking to? Forensic Doctor from Ningtai County? Forensic Doctor Jiang from Ningtai County?"

"Yes, I'm on speakerphone." Zhou Yuanqiang put down his phone and turned on speakerphone. A quick voice came from the phone: "No, no, what am I talking about?" "Hello, Medical Examiner Mei, I am Jiang Yuan from Ningtai." Jiang Yuan lowered his head and said hello to the phone.

The voice in the microphone suddenly stopped, and then several clear coughs were heard, and then he said in a soft voice: "Hello, forensic doctor Jiang, I am Mei Fang from Luyang. I actually talked to someone in our WeChat group before. You helped me look at the case where the remaining bones were left.

age and underlying diseases. "

"Oh, has the case been solved?" Jiang Yuan can only say that he has a slight impression. His daily use of WeChat is to help people look at bones and fingerprints. Fingerprints are usually complex fingerprints, and looking at bones is because there are too few experts who understand forensic anthropology.

Most forensic doctors have a background in pathology or clinical studies. They dare not call their study of forensic anthropology research. Most of them stop at school and slowly accumulate experience.

In fact, it is a state of not quite understanding. After all, there are already very few murder cases now, and it will take even longer for another corpse case or bones case to come up, and such a case will not be the turn of local forensic doctors to practice.

Mei Fang from Luyang City is actually a relatively powerful forensic doctor. Therefore, he is qualified to ask experts like Jiang Yuan about forensic anthropology. After all, he is a forensic doctor in the municipal bureau. In addition to major and important cases every year, he also Those who constantly support the counties and districts below see and know much more than ordinary county bureau forensic doctors.

Of course, it can't be a forensic doctor like Jiang Yuan.

Mei Fang said calmly: "The case has been solved. The murderer is a fair-weather friend from the next village. Did Dr. Jiang just say that there was something wrong with the time of death of a corpse?"

Jiang Yuandao: "Li Yuan in the 805 case, the first corpse discovered, I think the time of death was postponed by two months. This is mainly based on the larvae of the Xinluyuan Flies that I saw in the photos. Are you based on this?" There must be an error in the time of table retrieval. During the spring rain season in Luyang, the temperature was low and the corpses were not buried deep enough. The hatching rate of fly eggs was reduced. Furthermore, the rainy environment also affected the normal collection of maggots. food, delayed pupation is also common.”

"That's what you're talking about." Mei Fang's voice was weak and not as loud as usual. Zhou Yuanqiang couldn't help but get up and look at his phone. It was indeed his usually confident Dr. Mei.

Jiang Yuan did not explain his judgment method in detail in the office before. Now facing his peers, he continued to output: "The developmental model of necrophilic insects we use now should be used flexibly. Different regions The temperature, sunshine and even soil conditions have to change. The corpses of the 805 case were buried relatively shallowly and were greatly affected by various aspects. Spring is actually a season of changing temperatures. The local temperature difference in Luyang is large, and the Xinlu Plain The development speed of the fly under variable temperature is much faster than that under constant temperature. According to the literature, the development period is 69 days shorter than that under constant temperature. Of course, this is only as evidence."

Mei Fang said in a small voice: "That's what you said."

Zhou Yuanqiang couldn't help it anymore, and took the opportunity to interject: "Forensic Doctor Mei, didn't we also ask Forensic Doctor Zhai to check the situation?"

"That's not what I mean." Mei Fang didn't have time to stop her.

Zhou Yuanqiang said: "Not only was the death time of Corpse No. 1 checked by Forensic Doctor Zhai from the provincial department, but the merger of corpses No. 1 and 2 was also determined by Forensic Doctor Zhai. We don't just calculate the time casually."

In Zhou Yuanqiang's opinion, although Jiang Yuan is quite famous, he looks pretty good now. But Forensic Doctor Zhai has been famous for a long time and is a well-known forensic expert in the provincial department. Many cases in Shannan Province have been solved by Forensic Doctor Zhai in recent years. With this trump card, he will certainly be worthy of his name.

From his point of view, Jiang Yuan is an expert, and forensic doctor Zhai is a more famous provincial expert. If it must be said, the latter is more authoritative than the former.

Jiang Yuan had cooperated with Forensic Doctor Zhai before. When Liu Jinghui disappeared, the forensic doctor sent by the provincial department to support him was Forensic Doctor Zhai, and he was indeed a well-known forensic expert.

Jiang Yuan then said: "Then let's start a multi-person video and call forensic doctor Zhai over to discuss it together."

This time, Jiang Yuan did not use Zhou Yuanqiang's mobile phone. He directly used his own mobile phone to hold a multi-person meeting and added Forensic Doctor Mei and Forensic Officer Zhai.

Seeing that it was Jiang Yuan's invitation, Forensic Doctor Zhai accepted it in a daze.

Jiang Yuan briefly introduced the situation to Forensic Zhai. Considering the rank of Forensic Zhai, Jiang Yuan increased the difficulty a little and began to output: "The insect development model used by Forensic Zhai should be an isomorphic model.

. There is actually nothing wrong with this model, but I found something similar to flower fertilizer in the photo. At this time, I tried it with both the isozoan long-term model and the accumulated temperature model. The problem with the isozoan long-term model was not big, but There is obviously a discrepancy in the accumulated temperature model.”

Forensic doctor Zhai has paid attention to and contacted Jiang Yuan since he rescued Liu Jinghui.

The two of them also coexisted in multiple groups, and they often discussed the identification of time of death with each other. In fact, it didn't take many times. As long as they paid attention to the group from time to time, forensic doctor Zhai had already determined Jiang Yuan's strength.

At this time, Forensic Doctor Zhai said even more feebly: "Forensic Doctor Jiang, you are more authoritative than me in determining the time of death. You don't have to explain to me that I am indeed using an isozoan model. Some variables have not been taken into account clearly. This is true." I will study it later and study it, and you can follow your own path."

"As for corpse No. 1 in the 805 case, I revised the death time of the deceased Li Yuan to four months before the discovery." Jiang Yuan asked.

"Of course. No problem. I also agree with your judgment." Forensic doctor Zhai was a thin old man. When he said this, he said even more tiredly: "I am also dissecting a corpse here, so let's do this first ?”

"Okay." Jiang Yuan said a few more words to Medical Examiner Mei and ended the video conference completely.

Jiang Yuan put away his cell phone, looked at Zhou Yuanqiang, and asked: "Political Commissar Zhou, the time of death is four months?" "Okay?" No matter how unconvinced Zhou Yuanqiang was, he couldn't say one, two, three or four at this time.

Qu Hao, the squadron leader beside him, secretly sent a WeChat message to Mei Fang, asking: [Forensic Doctor Mei, what happened just now? 】

Forensic Doctor Mei: [Are you with the political commissar? What are you doing? Are you dragging me to be beaten? Qu Hao: [Isn’t this the time of death where everyone has a disagreement? 】

Forensic Mei first sent several angry expressions, and then sent a message: [Why do you have differences with Jiang Yuan? If you want to be embarrassed, then embarrass yourself. Why do you want to embarrass me too? And forensic doctor Zhai, you actually dragged forensic doctor Zhai to be beaten together? 】

Qu Hao: [That’s not the case]

Forensic Doctor Mei: [Next time I want to invite Forensic Doctor Zhai, if you go and invite me, I will be shameless! 】At this time, Jiang Yuan had already begun to describe the fertilizer, the murder weapon, and the conjecture of more corpses.

Qu Hao took a peek at Zhou Yuanqiang and curled up his neck silently. This feeling of being ridden on the face was not good at all.
