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

Tang Jia glanced at him and said, "We are working on Lu Yang's case. When people heard about it, they took the initiative to come to the door, which is considered a positive attitude. Don't offend them."

"Don't ask the teacher to blame." Shen Yaowei smiled.

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

"Lu Yang has worked on this case for a long time, but it shouldn't be so. It's always a good thing to have someone help solve the case. We can't just let it go. They will be the ones who will be unlucky then." Liu Jinghui still had nothing to say. During his tenure in Luyang, Chai Tong, the chief of the bureau, was not in charge of criminal investigation. Now that Jiang Yuan has been chosen to handle Luyang's case, there may be some strategy in it.

"Go and meet." Jiang Yuan got up and went out.Huang Qiangmin's office.

Two criminal police officers from Luyang City were sitting in a state of distress.

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

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

"Didn't Director Chai connect?" Jiang Yuan directly pointed out Chai Tong.

"Boss Chai was talking to our director, so we came here quickly. I have heard the name of Jiang Yuanjiang's forensic doctor many times this year. I don't know what the rules are on your side?" Zhou Yuanqiang was obviously a little unconvinced. Of course, being a policeman is similar to being a soldier, and it's not surprising that they all have the temperament of being the best in the world.

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

Turning his head, Jiang Yuan looked at the two criminal police officers from Luyang City again, and they both became a little impatient, and said, "Why don't I talk about our current progress?"

"Yes." It was obviously impossible for Zhou Yuanqiang to refuse the news.For the current Luyang Criminal Police Detachment, the 805 case has long been a heart disease. Over the past few years, they have to spend several months on this case every year, and the more they pay, the more they are concerned about this case. sensitive.

Jiang Yuan felt a little bit of their urgency, and he didn't show off, saying: "First of all, based on the photos in the file, I first re-identified the death time of the No. 4 corpse, that is, the deceased Li Yuan. I think The time of death should be postponed by two months, that is, four months before the discovery of the body, not half a year..."

"You can tell just by looking at the photos?" Zhou Yuanqiang couldn't help but retort when he heard this, and said, "Even if Jiang Fayi is famous, this is too arbitrary."

"Commissioner Zhou, you are not a professional. Why don't you call your forensic doctor and let me chat with him? We also discuss with each other." Jiang Yuan didn't get angry with this position. As he said, Zhou Yuanqiang was neither a forensic doctor nor a forensic doctor. He's not a criminal technician, so it's pointless to argue with him.

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

Zhou Yuanqiang held his breath a little and then looked at Huang Qiangmin beside him, with a faint smile on the corner of his mouth, so he lowered his head and dialed the phone.The phone connects.

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

"Is the time of death wrong?" Forensic doctor Mei on the other end of the phone repeated, her smile froze instantly, and she hurriedly said, "Who are you talking to? Forensic doctor in Ningtai County? Forensic doctor Jiang in Ningtai County?"

"Yes, I turned on the speakerphone." Zhou Yuanqiang put down the phone and turned on the speakerphone.A hurried voice came from the microphone: "No, no, what am I talking about?" "Hello Mei Forensic Doctor, I'm Jiang Yuan from Ningtai." Jiang Yuan bowed his head and greeted the phone.

The voice in the microphone stopped suddenly, and then I heard several clear coughs, and then said softly: "Hello Jiang Fayi, I am Mei Fang from Luyang, we actually talked in the WeChat group, there was a person who only The case with the remaining bones, you can help me look at it, it has been broken for a year

age and underlying diseases. "

"Oh, has the case been solved?" Jiang Yuan can only say that he has a slight impression. He plays WeChat every day, and the most he does is to help people look at bones and fingerprints.Fingerprints are usually complicated fingerprints, and looking at bones is because there are too few experts who understand forensic anthropology.

Most of the forensic doctors have a background in pathology or clinical science. For the study of forensic anthropology, they dare not call it research. Most of them stop at school and gradually accumulate experience.

In fact, it is a state of not understanding.After all, there are few homicide cases now, and it will take longer if it is the turn of a dismemberment case or a white bone case, and such a case cannot be practiced by a small local forensic doctor.

Mei Fang of Luyang City is actually a relatively powerful forensic doctor, so he is qualified to ask an expert like Jiang Yuan about forensic anthropology. After all, he is a forensic doctor of the Municipal Bureau. Those who keep supporting the districts and counties below know much more than the forensic doctors of ordinary county bureaus.

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

Mei Fang Qiqi Ai Ai said: "The case is broken. The murderer is a friend of the next village. That. Forensic doctor Jiang, just now said that there is a problem with the death time of a corpse?"

Jiang Yuandao: "Li Yuan of the 805 case, the first body found, I think the time of death was postponed by two months. This is mainly based on the larvae of the new Luyuan fly fly that I saw in the photos. Are you based on There must be some errors in the search time of the table. Luyang was in the spring rainy season, the temperature was low, and the corpses were not buried deep enough, so the hatching rate of fly eggs would be reduced. Furthermore, the rainy environment would also affect the normal extraction of maggots. food, delayed pupation is also common.”

"That's what you said." Mei Fang's voice was slightly weaker than usual.Zhou Yuanqiang couldn't help but get up and look at his phone. It was indeed Mei's forensic doctor who was usually full of confidence.

In the office before, Jiang Yuan did not explain his judgment method in detail. Now facing his peers, he continued to output: "The developmental model of necrophagous insects we are using now needs to be used flexibly. Different regions The temperature, sunlight and even the soil conditions have to be changed. The corpse of the 805 case was buried relatively shallow and was greatly affected by various aspects. Spring is actually a temperature-changing season. Under variable temperature, its development speed is much faster than 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 said in a small voice, "You are right."

Zhou Yuanqiang couldn't bear it at this time, and took the opportunity to interject: "Forensic doctor Mei, didn't we also ask forensic doctor Zhai to guard it?"

"That's not. That's not what it means." Mei Fang didn't even have time to stop it.

Zhou Yuanqiang said: "Not only the time of death of the No. [-] corpse was checked by the forensic doctor Zhai from the provincial department, but the merger of the first and second bodies was also determined by the forensic doctor Zhai. We didn't count the time casually."

From Zhou Yuanqiang's point of view, although Jiang Yuan is quite famous, he looks pretty awesome now.But forensic doctor Zhai has been famous for a long time, and he is a well-known forensic doctor in the provincial department. How many cases in Shannan Province have been solved by forensic doctor Zhai over the years.

From his point of view, Jiang Yuan is an expert, and Zhai Forensic Medicine is a more famous provincial and departmental expert. If one has to say something, the latter is more authoritative than the former.

Jiang Yuan had also 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 Dr. Zhai over to discuss it together."

This time, Jiang Yuan didn't need Zhou Yuanqiang's mobile phone, and directly used his own mobile phone to hold a multi-person meeting, adding Forensic Doctor Mei and Forensic Zhai.

Forensic doctor Zhai saw that it was Jiang Yuan's invitation, so he accepted it in a daze.

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

There is nothing wrong with this model, but I found something similar to flower fertilizer in the photos. At this time, I tried both the wait-length-line model and the accumulated temperature model. The problem with the wait-long-line model is not big, but The accumulated temperature model is obviously different.”

Zhai Forensic Doctor has paid attention to and contacted Jiang Yuan since rescuing Liu Jinghui.

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

At this moment, Forensic Zhai said even more feebly: "Forensic Jiang, you are more authoritative than me in identifying the time of death. You don't need to explain to me that I am indeed using the isomorphic line model. Some variables have not been considered clearly. This is true. It’s time to look back and I’ll study, study and learn, and you follow your train of thought.”

"The time of death of Li Yuan, the No. 805 corpse of the 4 case, I revised to [-] months before the discovery." Jiang Yuan asked.

"Of course. No problem. I also agree with your judgment." Forensic Zhai was originally a skinny little old man, and when he said this, he said very tiredly: "I am still dissecting a corpse here, so let's do this first ?”

"Okay." Jiang Yuan said a few more words to Forensic Mei, and the video conference was completely over.

Jiang Yuan put away his mobile phone, looked at Zhou Yuanqiang, and asked, "Commissioner Zhou, the time of death has come in 4 months?"

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

Forensic Mei: [Where are you with the political commissar?What are you doing?Pull me to be beaten? ] Qu Hao: [This is not about the time of death, everyone has a disagreement. 】

Forensic Mei first sent several angry expressions, and then sent a message: [Why do you have a disagreement with Jiang Yuan?If you want to lose face, you can lose face yourself, why drag me to lose face together?And forensic doctor Zhai, you guys are even beating up with forensic doctor Zhai? 】

Qu Hao: [That's not enough]

Forensic doctor Mei: [The next time you want to invite forensic doctor Zhai, you go and invite me, I am ashamed! ] At this time, Jiang Yuan had already begun to describe Huafei, the murder weapon, and more conjectures about the corpses.

Qu Hao took a peek at Zhou Yuanqiang, and silently shrunk his neck. This feeling of being beaten by someone's face is not good at all.
