Chapter 553: Life Response

"Hmm... the chef of Haidilao, I remember this."

"The case was not solved. My family had a dinner at Haidilao, but I didn't feel comfortable going."

"Me too. Later I found out that the people inside had changed. Many people resigned. The turnover rate was much higher than that of their other stores."

"Isn't it... didn't Jiang Yuan just come back? Is the case solved?"

"It will be soon. Pang Jidong has brought a group of people back for questioning."

Several criminal police sat in the office, chatting excitedly. They may not know all the murders in the bureau, but at least they have heard of the murders that have been backlogged.

[A novel app that has been running stably for many years, comparable to the old version of the book chasing artifact, the source change app that old bookworms use,]

Because when a murder is about to enter the backlog stage, it means that it has entered a state of desperate medical treatment. At this time, many criminal police teams will be caught and naturally will learn relevant information.

Furthermore, the number of unsolved homicide cases is even smaller than that of the already small number of homicide cases. The police officers in the bureau are more or less aware of the unsolved homicide cases in recent years.

And the solving of such cases will naturally cause discussion.

In fact, looking at the various police stations, if it is not for the various "operations" organized by the ministries and provincial departments, the independent solving of their own unsolved homicide cases is somewhat special and accidental.

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

Solving unsolved homicide cases through "operations" organized by higher-level departments is partly the benefit of resource integration, and partly more resources are thrown into it.

There are very few people who solve their own unsolved homicide cases from scratch.

On the contrary, there are some colleagues like Jiang Yuan from other police stations who, for some reason, solved the scenes here.

Of course, no matter from which angle, Jiang Yuan's ability to solve cases is far beyond the normal level, so that when ordinary criminal police discuss it, they seem more calm.

"Let's go, set off." A captain who returned from the meeting room waved his hand and called his men.

"The chef case of Haidilao?"

The criminal police had already talked about the gossip in the office, and guessed it at once.

The captain said "yes" and said: "The number of people on the list has doubled. We have assigned more than 20 people. Let's do it in detail. According to Director Xu, those who missed it last time will be forgiven. If anyone misses it again this time, the skin will be peeled off, the bones will be knocked out, and the files will be ground into the eyes."

"Got it." The criminal police were calm. It's just a threat, and it's not the first time.

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

Someone asked: "The direction of the investigation has not changed. Jiang Yuan also thinks that it was an acquaintance who committed the crime?"

"Yes."

"We have checked twice in the direction of acquaintances committing the crime. The probability of leakage is really low."

"So Director Xu also said that as long as it is not intentional, the leakage will not be investigated, but this time, we have to stand up."

"Is it really that the skilled are bold?"

The captain snorted twice and said: "They used bloodstain analysis to directly reconstruct the scene and performed it for all the leaders. I watched it and there was nothing wrong. I also believe that the most likely situation is that the acquaintance committed the crime."

Several criminal police frowned.

It is not uncommon to have loopholes during the investigation. The murderer of the Baiyin Eucalyptus escaped several times despite the unlimited attention of the police.

However, there must be a reason for the leakage, and it means that the eucalyptus criminal must have mastered some skills, which makes people have to consider more.

Funeral home

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

He did not plan to do an autopsy, so he did not ask the forensic doctor to thaw the body in advance, but only examined the body surface.

The cause of death of the victim was also relatively clear. During the first autopsy, no abnormalities were found, and Jiang Yuan did not need to do a second autopsy.

Autopsy is a destructive examination, and the more you do, the better. A typical example is the four autopsies of a woman surnamed Huang. Because the family members requested in various ways, when the fourth autopsy was done, the forensic doctor of the ministry saw a half-rotten body directly, and naturally could not find any results.

Jiang Yuan also focused on checking the wound, measured it with a ruler, and compared it with the results of the autopsy, saying: "The murderer should be a male, with strong strength and a height of between 170 cm and 180 cm."

This is determined by the angle of the chopping. And for such an important thing as chopping, generally speaking, few people jump up to chop, and they will not 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, so the height range is relatively large.

Jiang Yuan's estimate is already relatively clear.

It's just that the murderer's height is not good. A male with a height of 170 cm to 180 cm is almost useless for screening people.

The forensic doctor of Luojin City stood obediently by the side, not showing any disrespect at all because of Jiang Yuan's seemingly nonsense judgment.

Forensic botany, there are not many serious forensic doctors who do this. To put it another way, people have reached this level, is there any wall left in the forensic field? Jiang Yuan's head will smash the wall if it hits it.

"The first axe should have killed the man." Jiang Yuan carefully looked at the wound again, and waved his bare hands twice in the air, saying: "At this angle, there is no blood on the body. He is also a person who knows how to use an axe."

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

The forensic doctor of Luojin City nodded in agreement.

"From this point of view, there is still a certain interval between the first and second axe, and the murderer's emotions should not be particularly excited." Jiang Yuan carefully looked at the wound and gave the most valuable judgment today.

Part of his judgment was based on bloodstain analysis.

The forensic doctor of Luojin City did not have this part of the reserve, so he could only pretend to listen.

"Only the first axe splattered blood on the wall. I thought the second axe might be in the wrong position, but now it seems to be fine." Jiang Yuan said this, and the forensic doctor of Luojin City immediately understood.

Just like the story of the Three Kingdoms that Jiang Yuan told Pang Jidong, the blood splattered means that the victim was chopped while alive. In the professional terminology of forensic medicine, it is called life reaction.

When the second axe was chopped, the victim had no life reaction. There are two possibilities. One is that the position of the axe was off and there were no large blood vessels. The second is that the time is up and the victim's heart and internal organs have stopped working at this time, so there is 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 short time, and then chopped the second axe, the third...

A murderer who kills in passion usually doesn't do this.

A typical murderer who kills in passion is a madman who is seen on the street waving a knife randomly. Normal people will not kill people in normal conditions. They will only do so when they are mad and their brains have completely lost their minds.

Therefore, the murderer who committed a murder in passion should be chopping randomly with an axe in hand.

In this case, the murderer waited for a period of time between the first and second axe swings until the person was completely dead, that is, the murderer swung the second axe.

What was the murderer doing during this time?

Either observing or talking.

It is impossible that he threw an axe and then took out his mobile phone to start reading a novel.

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

Jiang Yuan nodded.

The forensic doctor of Luojin City frowned and said, "But, if there is a grudge or interest conflict, how can we not find it if we have checked the acquaintance twice?"

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

"Okay. Push the body back." Jiang Yuan saw that the victim had no intention of leaving him a legacy, so he could only let it go back to the ice coffin.

After Mu Zhiyang drove back, the yard of the Luojin City Criminal Police Detachment was already quiet.

Most of the criminal police had gone out to investigate and question.

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

Not only was it difficult to contact them, but it was even more difficult to ask them in person.

If it was a small case, the criminal police might have called, but for such a long-standing case, calls were absolutely not allowed, and they could only send people on business trips to question.

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

Jiang Yuan didn't seem very worried. When he returned to the temporary office, he called Pang Jidong, looking like he was reorganizing, and said: "Captain Pang, investigation is investigation, while waiting, let's do another case?"

"Find another chef case?" Pang Jidong guessed Jiang Yuan's mind.

Jiang Yuan smiled: "It's not necessary to choose a chef, this case is not over yet. For a new case, let's give priority to a forensic botany expert."

Pang Jidong felt his stomach curl up: "Are you really not worried about the results of the investigation? Should we take this opportunity to consider the direction of the investigation?"

"Looking at it again, it seems that the case was committed by an acquaintance. If we really can't find out, I will introduce an expert to you later." The three words Xu Taining flashed through Jiang Yuan's mind, but he didn't say it immediately, lest the people from Luojin Municipal Bureau object in advance.
