National Forensic Doctor

"The deceased was killed by a blunt instrument. The murder weapon was not found, right? Is there anything missing from the clinic?"

Jiang Yuan flipped through the photos one by one. First I looked at the photos of the deceased’s body in the file, and then I looked at the photos of the scene where the body was found. However, because it was the document that Yu Wenshu brought with him, the content was not complete and a lot of content was missing. Jiang Yuan had no clue for a while.

Judging from the injuries on the head of the deceased alone, the murder weapon should be a heavier cylindrical object, similar to an infusion bottle or a beer bottle. This is also reflected in the forensic report of the Changyang City Criminal Police Detachment, but because there were no debris at the scene, The murder weapon was not found, and it is still unclear what the murder weapon was.

Yu Wenshu also understood what Jiang Yuan meant, shook his head, and said: "The clinic has been checked, but the deceased ran the clinic independently. He did all the doctoring, medicine and hanging bottles by himself. What is the inventory and what items are there? Not sure yet.”

"It's not confirmed at the first scene, right?" Jiang Yuan asked again.

Yu Wenshu coughed twice, nodded, and said: "The clinic is in the village. It is relatively large, with two floors facing the road, and two yards at the front and back. In addition to the villagers in the village, there are also people from nearby factories. Employees come to see doctors and buy medicines, and the staff is also quite mixed..."

Yu Wenshu said this, still a little embarrassed.

In three days, the progress of the case could be said to be stagnant. The most important factor in a corpse dumping case is supposed to be determining the source of the corpse. However, after the task force completed the work, there was no progress, which made Yu Wenshu anxious.

The golden moment of the current case is so short, and now it has been basically squandered. Even if Jiang Yuan doesn't come back this time, Yu Wenshu will ask someone to bring the file to him for consultation.

Of course, it would be best if Jiang Yuan himself was present.

Jiang Yuan looked at the photos in the file and pondered.

In fact, there is nothing wrong with the idea of ​​​​the task force. It is common for the murder weapon to be found in corpse dumping cases. Many murderers will discard the corpse and the murder weapon separately. They may be relatively close to each other, but the murderer only needs to walk back for five minutes. The distance will increase the search workload greatly, not to mention that there are water bodies of different depths nearby.

In a normal corpse dumping case, if no direct evidence such as DNA or fingerprints can be found at the scene, it is the most normal approach to find possible suspects through interpersonal relationships after determining the source of the corpse.

Because usually only the murderer who knows the victim will choose to dump the body.

"In terms of interpersonal relationships, it's okay to check." Jiang Yuan thought for a while and said, "For the rest, let's go back and look at the corpse."

"Well, I hope I can gain something." Yu Wenshu is also a very experienced criminal police detachment leader, and based on his experience, the deceased has such interpersonal relationships throughout the village, and he wants to find the suspect through interpersonal relationships. Come on, it's just luck.

(Part of the distribution of interpersonal relationships in cases that resulted in the death of the victim in 240 indictments in a coastal city)

"Call Liu to work on the case together." Jiang Yuan didn't like this kind of guessing case. If he wanted to find clues from every detail, let Liu Jinghui do it.

Yu Wenshu was naturally very happy and took the initiative: "I'll talk to the provincial department and ask Liu Chu to come over for support."

Coster arrived at the criminal police detachment smoothly.

Everyone welcomes him.

After the ceremony, Jiang Yuan went straight to the conference room and read the files related to the case.

The police officers also took boxes of evidence and handed them to Jiang Yuan for inspection.

Ordinary experts would not be treated like this if they came here. There is a lot of evidence involved in the murder case, especially the evidence in the investigation stage. Many of them may not be used later. However, when they are all pulled out at this stage, they fill the entire conference room.

Jiang Yuan watched one piece after another, and at the same time reminded the forensic doctor to thaw the body.

The corpse has been dissected and will naturally be stuffed into an ice coffin and frozen for preservation. Now that Jiang Yuan is here and wants to re-examine, he can only take it out of the ice coffin and thaw it before looking at it. Otherwise, there might still be ice particles hanging on the hard body, making it difficult to perform a physical examination.

The next day.

Liu Jinghui took the bus at 7:30 in the morning and arrived at the criminal police detachment at 8:40. After saying hello to the police officers on duty, he was immersed in piles of documents.

For reasoning professionals, in order to take over a case, they not only need to understand the overall picture of the case, but also need to understand the details of the case. This is a very time-consuming and labor-intensive process.

Fortunately, Liu Jinghui still likes it. It's better than staying at home and making breakfast for your wife.

Jiang Yuan slept in his small house. After waking up, he had breakfast in a familiar shop downstairs, and then took the Alpha that had been reserved in advance to the Criminal Science and Technology Center.

Wan Baoming, the director of the Criminal Investigation Center, was also an old acquaintance. When he saw Jiang Yuan, he pretended to be relieved: "Jiang Yuan, it would be nice if you came. The body is almost thawed. I also asked someone to prepare hot pot. Let’s have hot pot together for lunch.”

The first autopsy usually takes more than three hours. If it is done carefully, it will take a lot of time in the follow-up. The time for the second autopsy can be long or short, but including the time to change clothes and take a shower, it's not even an hour before and after. Then look at the specimens and other things, go to the autopsy room, the corpse must open up, The forensic doctor also had to donate a morning.

In addition, anyone who has done an autopsy knows that this job is quite physically demanding, so having a hot pot meal after the autopsy is definitely very happy.

Jiang Yuan smiled and nodded, and said: "If I can see the corpse, I will have hot pot for lunch. The forensic doctor in charge this time is..."

"I did the dissection the first time." The person who spoke was forensic doctor Tang Feng. He and Jiang Yuan had collaborated several times and had hot pot together in the autopsy room, but facing Jiang Yuan, Tang Feng still felt a little guilty.

There are still many uncontrollable factors in forensic examinations. The so-called rules and science, when facing the complex human body, often require subjective judgment to intervene if you want to obtain a certain result.

At this time, the ranks of different forensic doctors became very obvious.

As an adult, especially a high-level adult technician in his thirties, Tang Feng also tried to learn from Jiang Yuan, but like many of his peers, it only made it more difficult for him to see Jiang Yuan again. resistance.

Jiang Yuan smiled and nodded to Tang Feng, asked a few casual questions, and they walked into the elevator together.

Wan Baoming and others sent Jiang Yuan all the way to the anatomy room, then turned around and left. Most people are not willing to take bath twice after picking up someone once.

Anatomy room.

The corpse was not completely softened, just enough to be cut open without being too soft. The state of the corpse at this time is similar to the state when cutting thin slices of meat at home. The knife slides in and feels a bit astringent, making it easier to cut than if it is completely thawed.

Of course, keeping the body in such a state is due to another consideration.

Because the surface marks of a corpse in a frozen state will be clearer. For forensic doctors, if the corpse is frozen, the damage on the surface of the corpse will be more obvious.

If there are less obvious indentations on the body surface, they can be more easily revealed at this time. However, this level of exposure is more suitable for forensic doctors below LV3, or allowing high-level forensic doctors to improve efficiency cannot solve the problem from 0 to 1.

For example, when Jiang Yuan went to Malaysia this time, he did the first negative autopsy case, which also involved observing corpses in a frozen state. There were no traces of the body surface at that time.

However, the traces of the frozen corpse are clearer, and the tool for identifying damage is naturally more convenient.

In particular, it is helpful to identify the shape of the striking surface, the angle of impact of the object, etc.

Tang Feng took the opportunity to re-measure the length of the injured area of ​​the deceased to avoid appearing too idle.

Jiang Yuan looked at the corpse and fell into deep thought.

"Are we going to do a second autopsy?" Tang Feng felt guilty again when he saw him like this.

"Then let's do a dissection." Jiang Yuan's answer was reasonable but unexpected.

A second dissection often means something went wrong with the first dissection.

Tang Feng couldn't help but ask: "Did you see anything?"

"It doesn't feel right. Let's cut it open and take a look." Jiang Yuan has reached his current position. There is no need to elaborate on the indicators and data. It is enough to talk about the feeling.
