"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 the Lu Yang case we were doing and took the initiative to come to the door. This is considered a positive attitude. Don't offend people."
"Don't just ask for help." 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 shouldn't be enough. It's always a good thing if someone helps solve the case. You can't just rely on it all the time. They will be the unlucky ones then." Liu Jinghui had nothing to say, but the new appointment
Director Chai Tong was not in charge of criminal investigation during his tenure in Luyang. Now that he has chosen Jiang Yuan to handle the Luyang case, I am afraid there is some strategy behind it.
"Let's go meet." Jiang Yuan stood up and went out to Huang Qiangmin's office.
Two criminal policemen from Luyang City were sitting at attention.
When Jiang Yuan enters, he can 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.
"Chai Bureau was chatting with our director, so we came over quickly. I have 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 are similar to soldiers, and they all have the aura of being the best in the world.
Jiang Yuan glanced at Huang Qiangmin. Huang Qiangmin told him with his eyes that Director Chai sold this wave. Jiang Yuan expressed his knowledge with his eyes.
Turning around, 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 is obviously impossible for Zhou Yuanqiang to refuse this news. For the current Luyang City Criminal Police Detachment, the 805 case has long been a heartache. Over the past few years, they have to devote several months to this case every year.
, and the more you pay, the more sensitive you become to this case.
Jiang Yuan could vaguely feel their urgency, and he did not give in. "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, that is, four months before the body is found, instead of half a year..."
"You can tell just 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.
He is not a criminal technician, so 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 then looked at Huang Qiangmin beside him, with a smile on his face, so he lowered his head and dialed the phone. The call was connected.
Zhou Yuanqiang said angrily: "Mei Forensic Doctor, I am Zhou Yuanqiang. Yes, I have arrived in Ningtai County. The forensic doctor here feels 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? Let me talk." "Hello, Dr. Mei, I'm
Jiang Yuan from Ningtai." Jiang Yuan lowered his head and said hello to the mobile 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. The most common thing he does on WeChat every day is to help people look at bones and fingerprints. Fingerprints usually come from complex fingerprints, and looking at bones is because he knows forensic medicine.
There are too few experts in 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’s a state that I don’t quite understand. After all, there are already very few murder cases now. It will be even longer if there is another case of mutilated corpses or bones, and such cases cannot be dealt with by the local authorities.
The little forensic doctor went 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 cannot 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. Um, Medical Examiner Jiang, did you just say that there was something wrong with the time of death of a corpse?"
Jiang Yuandao: "Li Yuan, the first corpse found in the 805 case, I think the time of death must be 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 would be reduced. Furthermore, the rainy environment would also affect 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 weak, not as loud as usual. Zhou Yuanqiang couldn't help but stand up and looked at his phone. It was indeed Mei Fang, the usually confident medical examiner.
.
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 needs to be used flexibly. Different regions
The temperature, sunshine and even soil conditions will all have to change. The corpses of the 805 case were buried relatively shallowly and were greatly affected by various aspects. Spring is actually a temperature change season. 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 14.69 days shorter than that under constant temperature. Of course, this is only as evidence."
Mei Fang's voice was small: "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 it means." 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 view, Jiang Yuan is certainly well-known, and he seems to be quite good now. But Forensic Doctor Zhai has been famous for a long time, and is a well-known forensic expert in the provincial department. Forensic Doctor Zhai has been responsible for many cases in Shannan Province in recent years.
The person who came forward to detect the case, he had this trump card, so he was certainly worthy of Jiang Yuan's success.
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 didn't use Zhou Yuanqiang's mobile phone. He directly used his own mobile phone to hold a multi-person meeting, adding forensic doctors Mei and forensic doctors 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. Taking into account 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 isomorph 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 is 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 the time of death and other matters 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 moment, 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 need 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 and study later, 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 very 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 and the political commissar together? 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 Doctor Mei first sent several angry expressions, and then sent a message: [Why do you have differences with Jiang Yuan? If you want to embarrass yourself, then embarrass yourself, why are you dragging me into embarrassment? And Forensic Doctor Zhai, you even drag Zhai
Forensic doctors were beaten together?]
Qu Hao: [That’s not the case]
Forensic Doctor Mei: [Next time you want to invite Forensic Doctor Zhai, go and do it, I will be shameless!] At this time, Jiang Yuan had already begun to describe the fertilizer, the murder weapon, and more speculations about the corpses.
Qu Hao glanced at Zhou Yuanqiang and curled up his neck silently. This feeling of being ridiculed was not good at all.
