National Forensic Doctor

--When Huang Qiangmin came to the medical examiner's office, his head was still a little raw.

He asked Jiang Yuan to do the backlog, but the general process for doing the backlog was really not like this.

To put it more realistically, if the provincial department now carries out a "100-day backlog attack operation" or the like, by the end of the operation, some of the backlog cases prepared in advance will not be activated.

The criminal suspect will not cooperate with your police actions.

And when the current case becomes a backlog, it will always have some difficulties. Even if there are not, after it becomes a backlog, there should be some problems. There are almost no things that can be missed from the backlog.

A criminal police officer. Starting from the backlog of cases, everyone complains endlessly. In some places, being assigned to do a backlog investigation is as painful as being forced to wear small shoes, which is actually very painful.

This is like a salesperson who is still unsure about a customer after trying every possible means. At this time, can a different salesperson be able to handle it? There is a high probability that it still won’t be possible... This is a regular sales.

Huang Qiangmin is indeed optimistic about Jiang Yuan's ability. However, Jiang Yuan started to make noises just half a day after he came back. Huang Qiangmin still doesn't understand the ordinary large-scale livestock reclamation. It will take several months, so he has to waste some feed and labor. , will it take a while to get results? 7 Isn’t it normal for it to take three to five months to start a backlog of cases?

It takes just a few hours to get it done. Is there something wrong with them and put it on the backlog? It's not steak. It can be done quickly.

"What clues did you find?" Huang Qiangmin still had a serious face when he entered the door. Although he was indeed very curious, the dignity of the captain must be guaranteed. If a leader loses his dignity, how can he manage his subordinates?

Ask Jiang Yuan to tell you what he found. "Wu Jun doesn't take credit. He doesn't have to consider the issue of dignity. He has already settled the treatment of his associate subjects and has no desires or desires before retirement.

While Jiang Yuan was waiting for someone, he had already prepared the pictures and made them into ppt. At this time, he turned to the screen and said, "It's the 611 He Jingqin case 13 years ago..." Oh, I Remember, the scene was full of blood

Yes, I did an on-site reconstruction based on the blood stains. "Jiang Yuan operated the ppt with his left hand and made some gestures with his right hand. Wu Jun smiled across from him. Hearing this, he was surprised. When did you do the on-site reconstruction? When you were doing the ppt, you did it by the way," Jiang Yuan replied.

Bloodstain analysis is a high-end thing. To play it well, you need to be at level 3. However, for Jiang Yuan, who has mastered the level 5 bloodstain analysis, reconstructing the scene is very basic. He has seen all the pictures that need to be seen and all the necessary information. It is a process of integrated analysis.

Jiang Yuan did not hesitate, first he showed a few photos, and then said, "I will not go into details about the investigation of the crime scene and the examination report of the body. I will directly talk about the reconstruction of the crime process.

"Based on the analysis of the blood stains, the murderer's crime process can be divided into four parts."

"In the first part, the murderer held the victim hostage, and started injuring the victim with a knife for the first time at the fire door. The victim's arm had superficial scratches, and he probably performed low-intensity defense here. Door The blood stains left on the wall behind may have been caused by pushing. The main basis is: a. The blood stains formed by flowing from top to bottom on the front of the victim's shirt. b!!!

"Part 2. The murderer took the victim hostage to the rooftop. The victim probably understood the murderer's purpose, and then resisted more fiercely, possibly accompanied by shouts. The murderer held a knife in his right hand and scratched the fatal wound from left to right. The wound was on the victim's neck, resulting in a splatter-like blood stain... Then, the murderer dragged the victim into the rooftop, causing drag injuries and a certain degree of resistance... The main basis...

In the third part, the murderer stabbed the victim again on the rooftop, causing the victim's death. The main basis is: a, bleeding-like blood 8, the formation of a pool of blood... c, the victim's footprints... d, the victim was lying down After that, spurting blood stains appeared again

In the fourth part, the killer begins wiping and cleaning the scene. The main purpose was to clean up the large pool of blood on the ground and close the door to the rooftop. I think this was to cover up the crime scene and avoid being discovered prematurely. From this, it can be inferred that after the murder, the murderer’s first consideration was to run away. Lu left, mainly because Huang Qiangmin looked dumbfounded. The captain of his county's criminal police brigade is here.

Looking at the photos, it was as if he had seen it with his own eyes, describing the on-site reconstruction of criminals' actions. He had also watched performances before. "Where did you learn this?" Huang Qiangmin really couldn't figure it out.

Jiang Yuan was silent for two seconds and said, "When I was studying, I liked to think about these things.

"Then you've really figured out something." Huang Qiangmin didn't know what to say. It's like the lead cow came out to work, but it ended up doing all the work of a production team. So as the captain of the production team, what should he do now? "Jiang Yuandao" I read the previous files, Mainly starting from the victim's family background to find the murderer. I think that by changing the angle of investigation, there might be a chance to solve the case."

An ex-convict who ran away after committing a crime? This country is also very big." Huang Qiangmin instinctively looked for loopholes.

The murder case backlog has been launched. In the blink of an eye, several police officers may have to be put in. It may take several months to solve the case. Preliminary arguments are indispensable.

Jiang Yuan then explained the previous body shape judgment based on the footprints, and then said: "I think we can narrow the scope a little first. If it doesn't work, we can expand it and think about how to narrow it down."

"I think it can be assumed that the murderer has a history of sexual crimes and was released for a short period of time, such as one or two months, no more than three months. Then, he ran away very quickly and should have left on the same day. ∶No more than the next day,” “Why is the release time so short?” Huang Qiangmin thinks this issue is the most important,

There are only a few prisons in the province, and considering the criminals from Shoutai County, the number of sex offenders released after serving their sentences in the three months before the incident was probably very small. If it doesn't work, just a few people.

Among such a small number of people, if you find someone between 25 and 30 years old, the number will be even smaller.

After Jiang Yuan pondered some words, he turned off the ppt, found a few more photos, and said: "From my understanding of the crime scene, the murderer's tidying up behavior was relatively calm. But his actions, I think he is a little eager and a little unfamiliar. That is... he is very courageous and confident in the process of committing crimes, but he is also anxious..."

What Jiang Yuan described at this time was already an overall judgment, rather than a separate point-to-point judgment: "I think this time is the first time the murderer committed a crime after being released from prison, so he is particularly... impatient. ,

Huang Qiangmin understood. Although he himself did not know much about blood stain analysis, Jiang Yuan had already analyzed it to this extent, so Huang Qiangmin could only choose to believe it.

"You guys investigate first. Let's see where we go. I'll find two people to help you." Huang Qiangmin thought for a while, then called Wei Zhenguo to come over for this case. If Jiang Yuan found fingerprints or DNA evidence, . Huang Qiangmin must have directly organized a project team, but for bloodstain analysis, Huang Qiangmin wanted to send two scouts out first.

This is also a general operation in the criminal police team. It can only be said that Jiang Yuan was not made special. This is what Jiang Yuan wanted. When Wei Zhenguo came over, the two discussed it and started making phone calls. The prison belongs to the judicial system. To manage, especially prisons outside the province, it is more troublesome. This is just a trouble, and it does not last long. Two days later

A list of only 8 people was placed on Huang Qiangmin's desk.

"There are only so many suspects?" At this moment, Huang Qiangmin's level of attention was instantly raised.

Jiang Yuan nodded and said, "I think the first four people on this list are the most likely ones. The last four people could have been screened out first and waited to see. But Captain Wei believes that there is no need to limit the range so narrowly...

"Old Wei is right, wait until I call someone over." Huang Qiangmin stopped approving the documents at hand and directly called the back office to call for someone.

While waiting for others, Huang Qiangmin said: "The list of suspects in the backlog of murder cases, 8 people are nothing, 80 people can be investigated directly. For this kind of case, we are not afraid of alerting the snake. With 8 people, we have enough manpower." ..."Yes," Jiang Yuan has also experienced several interrogations and arrests, and knows what the situation is like,

The police are not playing games when handling cases. They will not say that they have everything ready. After screening out the only results, the four squadron leaders and team deputy were called over in one breath and went directly to the conference room. "Jiang Yuan, please wait a moment." Let me update you on the case." Huang Qiangmin said and got up and headed to the conference room. Jiang Yuan is also ready.

No matter whether you arrest 8 people or 4 people, the specific circumstances of the case must be informed to the executing police. Arresting is always risky, and necessary information needs to be provided.

Jiang Yuan arrived in the conference room and released the ppt again. While operating with one hand, he reconstructed the crime scene more completely. Compared with the time when he explained it to Captain Huang Qiangmin, Jiang Yuan was better prepared this time. It’s also more complete. Several captains and deputy team members were also veteran criminal police officers, but after listening to Jiang Yuan's case report, they couldn't say for a long time, "Will future cases be done like this?" It took a long time before Comrade Wu Junhao of the No. 1 Squadron couldn't bear it. Live to speak

Of course it's impossible. "Liu Wenkai, the captain of the Second Squadron, sighed and said: "No matter how good Shang K is, he will not take away Fenglou's market. Don't worry. "

Everyone inexplicably agreed and felt a little bit of peace of mind.
