Chapter 553: Life Reactions
"Hmm... Haidilao's cook, I remember this."

"This case has not been solved. My family has dinner at Haidilao, and I am not ashamed to go."

"Me too. Later, I found out that the people inside have changed, and many people have resigned. The turnover rate is much higher than that of other stores."

"No... Didn't Jiang Yuan just come back? This case is solved?"

"Hurry up, Pang Jidong has brought a group of people back to ask."

Several detectives were sitting in the office, chatting happily.They may not know all the homicide cases in the bureau, but they have at least heard of the murder case backlog.

Because when a murder case is about to enter the backlog stage, it means that it has entered a state of being rushed to the doctor. At this time, many criminal police teams will be arrested, and they will naturally learn relevant information.

Furthermore, the backlog of homicide cases is smaller than the number of homicide cases that are not many. The police officers in the bureau will more or less understand the homicide cases that have not been solved in recent years.

And when such a case is detected, it will naturally arouse discussion.

In fact, looking at each police station, if it is not for the various "actions" organized by the ministries and departments, those who can independently solve their own homicide cases are all special and accidental.

The most common one is that the criminal suspect did other crimes and was then caught out.What's even cooler is that a certain criminal policeman has been following a certain case, and finally waited for the clues, and then solved it.

Through the "action" organized by the higher authorities to solve the backlog of homicide cases, part of it is the benefits obtained from the integration of resources, and part of it is that more resources have been poured into it.

There are too few people who solve their own homicide cases from the beginning.

On the contrary, like Jiang Yuan, colleagues from other police stations, for some reason, some of them solved the scene here by the way.

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

"Let's go, let's go." The captain of a certain brigade who returned from the meeting room waved and shouted to all his subordinates.

"Haidilao's cook case?"

The detectives had already chatted thoroughly about the gossip in the office, and they guessed it right away.

The captain gave an "En" and said: "The number of people on the list has doubled, we have allocated more than 20, and we should be more detailed. As for Director Xu, if he missed it last time, let it go, whoever missed it this time, skin peeling Yes, the bones were knocked out, ground up with a file and sprinkled in the eyes."

"Understood." The detectives' hearts did not fluctuate.It's just a threat, and it's not the first time.

However, if there are 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, and Jiang Yuan also thinks it is an acquaintance who committed the crime?"

"Correct."

"We have checked twice according to the direction of the acquaintance's crime. The probability of leakage is really not high."

"That's why Director Xu also said, forget the past, as long as it's not intentional, you won't be held accountable for leaking, but this time, you have to stand up."

"Is it really a person with a high level of art who is bold?"

The team leader snorted twice, and said, "He used the blood analysis method to directly reconstruct the scene, and performed it for all the leaders. I watched it, and there was nothing wrong with it. I also believe that the most likely situation is that an acquaintance committed the crime."

The brows of several criminal policemen also frowned.

It is not uncommon for loopholes to appear during the investigation. The murderer of the Baiyin case escaped several times under the circumstances that the police paid great attention to.

However, there must be a reason for the leak, and it shows that the criminal must have mastered some skills, which makes people have to think more.

funeral parlor.

Together with the forensic doctor in Luojin City, Jiang Yuan pulled the corpse out of the ice coffin.

He didn't plan to do an autopsy, so he didn't ask the forensic doctor to thaw the body in advance, but mainly checked the body form.

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

An 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 it in various ways, when it was the last fourth time, what the forensic doctor of the ministry saw was a half-decomposed corpse, and naturally they couldn't detect anything. The results come.

Jiang Yuan also focused on examining the wound, measured it with a ruler, and then compared it with the autopsy, and said: "The murderer should be a male, not weak in strength, and his height is between 170 cm and 180 cm."

This is determined by the angle at which you cut.As for such an important thing as beheading, generally speaking, few people jump up and slash, and they will not deliberately squat down to slash, so the height can be judged based on the angle.

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

The valuation given by Jiang Yuan is relatively clear.

It's just that the murderer's height is not strong. For men with a height of 170 cm to 180 cm, such a height value is almost useless for screening people.

The forensic doctor in Luojin City stood obediently by the side, without any disrespect because of Jiang Yuan's nonsense judgment.

For forensic botany, few serious forensic doctors do this. From another perspective, people have played to this level. Is there any challenge in the forensic field?If Jiang Yuan hit his head, it would probably smash the south wall.

"The first ax should have hacked the person to death." Jiang Yuan carefully looked at the situation of the wound, and waved his bare hand twice in the void, saying: "Slashing at this angle, there is no blood splashed on the body, And a man who knows how to use an ax."

If the murderer was spattered with blood, the splattered blood on the wall would not be complete.

The forensic doctor in Luojin City nodded in agreement.

"In this way, there is still a certain interval between the first ax and the second axe. The murderer should not be particularly excited." Jiang Yuan looked at the wound carefully and gave the most valuable one today. judge.

Part of his judgment was based on bloodstain analysis.

The forensic doctor in Luojin City did not have this part of the reserve, so they could only do a listening test.

"On the wall is the blood splatter from the first axe. I thought there might be a gap in the position of the second axe, but now it looks fine." When Jiang Yuan said this, the forensic doctor in Luojin City immediately understood.

Just like the story of Jiang Yuan telling Pang Jidong about the hacking of people in the Three Kingdoms, there was blood splattering, indicating that the victim was hacked while he was alive. In the professional term of forensic medicine, it is called life reaction.

When the second ax was struck, the victim had no life response. There are two possibilities. One is that the position of the ax is off and there are no large blood vessels. The second is that the time is up and the victim’s heart and internal organs have stopped Without work, there is no life response.

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 before he chopped the second axe, and the third...

A murderer who kills with passion is generally not like this.

A typical passionate murderer is a lunatic wielding a knife in the street. A normal person would not kill in a normal state. He would only do so when he was mad and his brain completely lost his mind.

Therefore, the murderer who kills with passion should be chopping randomly with an ax in his hand.

However, in this case, between swinging the first axe and the second axe, there was an interval of time for the entire life reaction to disappear, that is, the murderer swung the second axe only after the person was completely dead.

What was the murderer doing during this time?

Either watch or talk.

It's impossible to throw an axe, and then take out your phone and start reading novels.

"Is there any grievance or conflict of interest 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, I've checked the acquaintances twice. If there are any grievances or conflicts of interests, how could they not be found?"

Jiang Yuan shook his head, guessing without objective evidence, he is not interested.

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

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

Most of the criminal policemen went out to investigate and question.

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

Not only is it laborious to get in touch, but it is even more difficult to ask in person.

If it is a small case, the criminal police may call, but for this kind of homicide case, phone calls are absolutely not allowed, and people can only be sent on business trips to question.

At this time, the criminal police detachment was as empty as a holiday company.

Jiang Yuan didn't look very worried. When he returned to the temporary office, he called Pang Jidong, and said with a look of regrouping, "Pang Da team, the investigation is the investigation. Let's do another case during the waiting time?"

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

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

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

"It's an acquaintance who committed the crime. If you really can't find out, I'll introduce an expert to you later." The word Xu Taining flashed in Jiang Yuan's mind, but he didn't say it immediately, lest the Luojin City Bureau object in advance.
