Chapter 526: Life reaction

"Wu... Haidilao's cook case, I remember this."

"Since this case wasn't solved, I didn't even have the face to go to the family dinner at Hai Di Lao."

"Me too. Later, I found that the people inside had changed. Many people resigned, and the staff turnover rate was higher than other stores."

"No... Jiang Yuan just came back, right? This case is solved?"

"Soon, Captain Pang Jidong pulled a group of people back to inquire."

Several criminal police officers sat in the office, chatting excitedly. They didn't necessarily know all the murder cases in the bureau, but they had heard of cold cases.

Because when a murder case is about to enter the cold case stage, it means it has entered a state of being sick and seeking medical treatment. At this time, many criminal police teams will be caught, and they will naturally understand the relevant information.

Furthermore, cold cases are fewer than the murder cases that are not many to begin with. The police officers in the bureau will know more or less about the murder cases that have not been solved in recent years.

And the solving of such cases will naturally cause discussion.

In fact, looking at various police stations, if it is not for the various "actions" organized by the Ministry and the provincial department, those who can independently solve their own cold cases have a certain particularity and contingency.

The most common one is that the criminal suspect committed other cases and was then picked out. The cooler one is that a certain criminal police officer has been following a case and finally waited for clues, and then solved it.

Solving cold cases through "actions" organized by higher-level departments, part of it is the income obtained from resource integration, and part of it is more resources being thrown into it.

Starting from scratch to solve one's own cold cases is too rare.

Instead, like Jiang Yuan, colleagues from other police stations, because of some reason, have some cases that were solved along the way.

Of course, no matter from which angle you look at it, Jiang Yuan's ability to solve cases is far beyond the normal level, so that ordinary criminal police discuss it more and more calmly.

"Go, set off." A certain detachment leader waved his hand and called all his subordinates up.

"Haidilao cook case?"

The criminal police had already chatted through the gossip in the office, and guessed it as soon as they guessed it.

The detachment leader said "En," and said, "The number of people on the list has doubled. We have allocated more than 20, so make it detailed. Xu Ju said, the ones who ran away last time, let bygones be bygones. Whoever runs away this time, skin them, knock out the bones, grind them with a file and sprinkle them in their eyes."

"Understood." The criminal police had no waves in their hearts. It's just a threat, not the first time.

However, if there were problems with the previous investigation, this investigation really makes people have to pay more attention.

Someone asked, "The investigation direction has not changed, and Jiang Yuan also thinks it is an acquaintance committing the crime?"

"Yes."

"We have checked the direction of acquaintances committing crimes twice, and the probability of running away is really not high."

"So Xu Ju also said, let bygones be bygones. As long as it is not intentional, the matter of running away will not be pursued, but this time, we must stand up."

"Is it really art high and bold?"

The detachment leader hummed twice and said, "People used bloodstain analysis to directly reconstruct the scene and performed it for all the leaders. I saw it, no problem. I also believe that the most likely situation is an acquaintance committing the crime."

The brows of several criminal police officers also wrinkled.

It is not too rare for loopholes to appear during investigation. The murderer of the Silver Case ran away several times under the infinite attention of the police.

However, running away must have a reason, and it shows that the perpetrator must have mastered some skills, which makes people have to consider more.

Funeral home.

Jiang Yuan and the forensic doctor in Luojin City pulled the body out of the ice coffin.

He didn't prepare to perform an autopsy, so he didn't ask the forensic doctor to thaw the body in advance, just mainly checking the body surface.

The cause of death of the victim was also relatively clear. During the first autopsy, no abnormal situation was found, and there was no need for Jiang Yuan to perform a second autopsy.

Autopsy is a destructive examination, and it is not that the more you do, the better. A typical one is the four autopsies of the woman surnamed Huang. Because the family members requested it in various ways, by the time the fourth autopsy was done, the forensic doctor from the Ministry saw a half-decomposed body, and naturally, no results could be detected.

Jiang Yuan also focused on checking the wounds, measured them with a ruler, and compared them with the situation of the first autopsy, saying, "The murderer should be a male, not weak in strength, and between 170 cm and 180 cm in height."

This is determined by the angle of chopping. And for important things like chopping people, generally speaking, very few people jump up to chop, and they won't specifically squat down to chop, so the height can be judged according to the angle.

However, because the murder weapon has not been obtained yet, the length of the murder weapon can only be estimated. In this way, the height range is relatively large.

The estimated value given by Jiang Yuan is already relatively clear.

It's just that the murderer's height is not helpful. For a male between 170 cm and 180 cm, such a height value is almost useless for screening the crowd.

The forensic doctor in Luojin City stood obediently on the side, not because of Jiang Yuan's nonsense-like judgment, and had the slightest disrespect.

Forensic botany, there are not many forensic doctors who do this. To put it another way, people have played to this level, what south wall is there in the forensic world? Jiang Yuan's head hit it, and he would smash the south wall.

"The first axe should have chopped the person to death." Jiang Yuan looked at the wound carefully again, and waved his hands in the void, "This angle of chopping, and there is no blood splashed on the body, is also someone who knows how to use an axe."

If the murderer was splashed with blood, the bloodstains sprayed on the wall would not be complete.

The forensic doctor in Luojin City nodded in agreement.

"Looking at it this way, there should be a certain interval between the first axe and the second axe. The murderer's emotions should not be particularly agitated." Jiang Yuan looked at the wound carefully and gave the most valuable judgment today.

In this, part of it is judged according to bloodstain analysis.

The forensic doctor in Luojin City didn't have this part of the reserve, so he could only listen.

"There are only spray bloodstains of the first axe on the wall. Originally, I thought there might be a gap in the position of the second axe, but now it seems there is no problem." As soon as Jiang Yuan said this, the forensic doctor in Luojin City immediately understood.

Just like the story of chopping people in Three Kingdoms that Jiang Yuan told Captain Pang Jidong, there is spray blood, indicating that the victim was chopped while alive. In professional forensic terms, it is called life reaction.

When the second axe was chopped, the victim no longer had a life reaction. There are two possibilities for this. One is that the position of the chopping was biased, without large blood vessels. The second is that the time was up, the victim's heart and internal organs stopped working at this time, so there was no life reaction.

Jiang Yuan's judgment is that the time is up.

In this way, after the murderer chopped the first axe, he paused for a very short time, and then chopped the second axe, the third...

A murderer who commits a crime of passion generally doesn't do this.

A typical murderer who commits a crime of passion is a madman holding an axe and chopping wildly on the street. Normal people will not kill people in a normal state. Only when they are crazy and the brain completely loses reason will they do so.

Therefore, a murderer who commits a crime of passion should chop wildly with an axe in his hand.

And in this case, the perpetrator chopped the second axe after the interval between the first axe and the second axe, that is, until the person was completely dead.

What was the murderer doing during this time?

Either observing, or talking.

It is impossible to throw out an axe, and then take out a mobile phone and start reading a novel.

"Is there a grudge or interest dispute between the murderer and the victim?" The forensic doctor also thought about this question clearly.

Jiang Yuan nodded.

The forensic doctor in Luojin City frowned and said, "However, it is an acquaintance who has been checked twice. If there is a grudge or interest dispute, how can it not be found."

Jiang Yuan shook his head. He was not interested in guesses without objective evidence.

"Alright. Push the body back." Jiang Yuan saw that the victim didn't mean to give him a legacy, so he had to let it return to the ice coffin.

Mu Zhiyang drove back, and the courtyard of the Luojin City Criminal Police Detachment was quiet.

Most of the criminal police had set off to inquire.

After more than a year, many people on the list were no longer at the original address. Some people even changed cities and returned to their hometowns.

Not only is it laborious to contact, but it is even more difficult to inquire in person.

If it is a small case, the criminal police might just call, but for this kind of cold case, the phone is absolutely not allowed, and only people can be sent on business to ask questions.

At this time, the Criminal Police Detachment was as empty as a company on vacation.

Jiang Yuan was not very worried. Returning to the temporary office, he called Captain Pang Jidong, looking like he was regrouping, and said, "Detachment Leader Pang, investigation is investigation. During the waiting time, shall we do another case?"

"Find another cook case?" Captain Pang Jidong guessed Jiang Yuan's heart.

Jiang Yuan smiled, "It's not that I must choose a cook case. This case is not over yet. For the new case, let's prioritize finding one with forensic botany."

Captain Pang Jidong only felt that his stomach was curled up, "Are you really not worried about the result of the investigation? Shall we consider the investigation direction again during this time?"

"Looking at it again, it is still an acquaintance committing the crime. If it really can't be found, I will introduce an expert to you later." The name Xu Taining flashed in Jiang Yuan's mind, and he didn't say it immediately, so as not to let the Luojin City Bureau people oppose it in advance. ===== CHAPTER 527 =====
