"The murderer has surrendered!"

"The victim's ex-boyfriend, Han Shengyan, claimed that he had a conflict with the victim because of emotional problems. The time was about noon today..."

"This Han Shengyan has some mental problems, and his parents came with diagnostic reports and other things."

Chai Tong relayed the news he received, sighed, and put away his phone.

In the investigation stage, you can find logic for mental illness murder, but politically, it is difficult to link it with logical problems.

In other words, Chai Tong will eventually retreat with this wave of ebb.

"Professor Chen, thank you for your hard work." Chai Tong took two steps forward and prepared to take Professor Chen back with him.

The murderer has surrendered. Although a series of case handling links are still needed, for Chai Tong, this case is over.

Even if a forensic report is still needed, it will be the job of Jiang Yuan or Wu Jun. Professor Chen, an external aid, is not qualified to sign it.

Professor Chen stood up, feeling a little regretful, and said to Jiang Yuan: "I was thinking about doing some frontline work again, but I didn't get a good opportunity."

Whether you are a forensic doctor or an anatomy professor, you need dead people to cooperate if you want to do frontline work. It is normal that Professor Chen can't be found at ordinary times. In fact, in a place like Ningtai County, it is normal for a murder case to be closed automatically without being solved.

The murderer this time is a typical urban murderer with some mental problems. He escaped after killing passionately, and then returned to surrender under the persuasion of his family...

Although there are no statistics, similar murderers are really common.

Huang Qiangmin also came over and said to Jiang Yuan: "The scene investigation is almost done, so let's transport the body back."

Only some surface examinations can be done at the scene, and the specific autopsy report must be done back.

The surrounding police officers also stood up with some relief.

Jiang Yuan coughed twice and said: "Wait a moment."

"Huh?" Huang Qiangmin turned around in confusion.

"Who interrogated the murderer? It should not be done yet, right?" Jiang Yuan asked.

"It is being interrogated." Huang Qiangmin called back directly when he saw Jiang Yuan had doubts.

The call was connected, and Huang Qiangmin handed it to Jiang Yuan.

After a few greetings, Jiang Yuan asked: "When you ask for details, please confirm the time of the conflict, which should be relatively accurate, and the number of attacks and whether there was a return."

The first two sentences were normal, but the last return mentioned by Jiang Yuan was more attractive.

All the police were present, except Professor Chen, but everyone basically heard a little bit of the meaning.

Huang Qiangmin asked: "Is there a secondary injury?"

Professor Chen heard this and came over directly, re-examined the body, and said: "The back of the head was injured multiple times, but it cannot be confirmed that it was injured twice."

He himself has a superb academic level in anatomy, and he is naturally a good hand in forensic medicine, so he is very confident when he speaks.

Jiang Yuan nodded: "From the perspective of trauma, it is indeed difficult to distinguish. However, I think there is a problem with the time of the bloodstains. In addition, judging from the state of the body, the crime was not completed in one go."

"Bloodstains..." Professor Chen still lacks experience. He wants to judge the time of the bloodstains directly by looking at the bloodstains - it is not impossible for him to do it, but he may need to check the information and do some calculations.

After all, this is a very serious murder case. To give an accurate conclusion, it is necessary to comprehensively consider the environment at the scene, including whether there is direct sunlight, the temperature in the restaurant, etc.

Assuming that the victim died at noon, it is at most six or seven hours now. If there is a second crime in the middle, the time difference may be one or two hours if it is judged by blood.

In such a short time, whether the air conditioner is turned on in the restaurant, how strong the sunlight is, and whether there is wind may become key factors. Moreover, under different time dimensions, the situation in different regions in different seasons must be different. From the perspective of scholars, it is a lot of regression equations...

Professor Chen certainly can't memorize these things. He is an anatomist, and the difference between him and bloodstain analysis is like the difference between crocodiles and snapping turtles.

But Professor Chen actually felt that it was unnecessary to investigate now.

He asked directly: "How long do you think the time difference of the bloodstains is?"

"One and a half hours." Jiang Yuan said it in whole and small numbers, because for this murder case, this time difference is particularly important.

At the same time, Jiang Yuan is also quite confident.

To be honest, for the current case, Jiang Yuan currently has too many means.

A fresh corpse that died at noon, facing LV6 time of death identification, LV4 forensic pathology, and a full set of LV5 bloodstain analysis, crime scene investigation, etc., to be frank, Jiang Yuan knows how he died better than the victim himself.

And Jiang Yuan's answer completely pulled back the emotions of the people who had just relaxed.

Everyone is familiar with Jiang Yuan, and their confidence in him can be said to be stronger than their own wife.

Since Jiang Yuan mentioned the time difference issue, there are two explanations, one murderer, or two murderers.

If there is only one murderer, it would be easy. We can still interrogate the suspect who has surrendered himself. But if there are two murderers, how to find the second murderer is no longer a joke.

The survey boxes and other items that were just about to be put away were now adjusted to brightness, and they continued to search for fingerprints and footprints.

Jiang Yuan changed his gloves again, observing the blood stains while waiting for the results of the interrogation in the bureau.

Interrogation should not be a problem for criminal suspects who surrender. At the very least, it will be no problem to obtain some basic information.

Not long after, the call came.

Huang Qiangmin handed it directly to Jiang Yuan.

"Han Shengyan claimed that he did not turn back. As for the specific details of the violent conflict, Han Shengyan could not tell. The problem now is that he was stimulated by the incident and had a mental illness. His confession may be flawed." said the policeman on the phone. Try to be as concise as possible, and obviously understand that there are changes on the scene.

"Where are Han Shengyan's parents? When did they meet Han Shengyan?" Jiang Yuan asked.

"Around 4 p.m.," said the police officer at the station.

Calculating the time, there is just enough time to turn back once. But unless it was a deliberate turn back twice, otherwise, this time is already a bit rushed.

Huang Qiangmin said at this time: "You can use your mobile phone to check the last time you connected to the base station."

This requires you to apply to a technical detective.

Jiang Yuan nodded and activated the crime scene reconstruction skill (temporary +1 and lasting for 535 minutes).

This skill was acquired recently, and its reconstruction effect comes not only from bloodstain analysis, but also from crime scene investigation, and even image enhancement and other skills.

As far as the scene in front of me is concerned, it is at least equivalent to the level of blood stain analysis LV6.

"The victim hit the wall first."

Jiang Yuan looked at the scene again, stepped forward, called a technician to come over and take pictures, and said, "This place should be soaked in blood."

Professor Chen also walked over to take a look, nodded and said: "Indeed, it is, but it is normal for blood stains to form in a few hours."

"I bet there are still blood stains here." Jiang Yuan had said something before realizing that Professor Chen was a teacher, and said hurriedly: "What I mean is, judging from the blood-stained position, the victim should have moved. "

"You made a bold bet." Professor Chen didn't know what his state of mind was at this time. The fact that a student who had only graduated for two years could grow to such an extent even made him confused about the capabilities of his school. .

Jiang Yuan smiled, called two people over, and said, "Take the body away."

Then, the four people worked together to lift the body as lightly as possible.

After the body left, there were indeed obvious blood stains on the floor below.

Of course, there are many explanations for wiping blood stains. For example, if the deceased crawled hard before death, such blood stains may have formed.

However, crawling will obviously leave other marks around, such as bloody handprints, or marks of exertion on knees or feet.

Without these, and the body was lying on its back, the blood stains wiped off were probably passive displacement.

Professor Chen nodded slowly and couldn't help but said: "You really made the right bet."

Jiang Yuan acquiesced, this move was really difficult.

Director Chai Tongchai, who had been watching from the outside, suddenly felt particularly uncomfortable. Jiang Yuan's strength is a bit too strong. Moreover, such a powerful subordinate actually leaked out from his fingers?
