National Forensic Doctor

"Yes, why? This murderer is somewhat seriously ill."

Sitting in the small conference room, several members of the task force flipped through the updated information, re-read the various pictures provided by Jiang Yuan, and then threw away the dossier containing explosive maggots from a distance.

"Are the murderer and the person who dumped the body two people? The murderer killed someone at the first scene, dumped the body at the second scene, and the people at the second scene found the body. For some reason, they might not be able to call the police, so they dumped the body again?"

The person who spoke was Captain Ma Jiyang. He was the leader of the Changyang City Criminal Police Detachment. He had received three second-class merits in total. He had solved countless major cases and had rich experience. When he saw Jiang Yuan's report, he immediately made a reasonable guess.

Jiang Yuan slowly shook his head and said: "The time between the second dumping and the third dumping is relatively short, and the environment is relatively good. Otherwise, the body would have been dropped during the second dumping. With a lot of eggs, the difference between the flies will be even greater when the bodies are thrown away three times. "

Ma Jiyang thought matter-of-factly and said: "Then let's change it. The murderer did it independently. He killed people at the first scene and dumped the body at the second scene. For some reason, it was quickly moved to the third scene. A single person completed the two dumpings independently. , he was probably very tired, which could also explain why he dumped the body by the river instead of digging a hole and burying it. "

This speculation can be regarded as correcting the question raised by Jiang Yuan just now.

Jiang Yuan was noncommittal, it was indeed a possibility.

With Ma Jiyang taking the lead, someone immediately came up with a new idea:

‘It’s possible that the environment at the second scene was too complicated, or something unexpected happened, so we immediately moved to the third scene. As for the woven bag, I probably got it at the second scene. Will the remaining body parts still be at the second scene? "

"It's not easy to dispose of corpses again, especially with so many corpses. If one person does it, it would be almost as much work as my move. I would have to clean up the second scene. It would be better to dig a hole."

"Digging a hole is not necessarily more useful than dumping the body. I tend to be functional. It is likely that the first scene has a reason to be moved. It is a public place not controlled by the murderer, or the victim's place. Hastily move to the second scene Location, the second location is probably a place where the murderer feels safe, such as his own home, where he then found a place to dump the body and carried out dismemberment and other operations simultaneously. "

When Jiang Yuan heard this, he couldn't help but nodded and said: "Judging from the hacking marks on the house, it is likely that a Chinese kitchen knife was used to separate the houses.

Therefore, the second scene is very likely that the murderer dismembered the body at home. "

Domestic forensic research on weapons such as kitchen knives has been very detailed. First of all, kitchen knives are heavy handled sharp instruments, but compared with similar heavy handled sharp instruments, the cutting wounds of kitchen knives are often longer and deeper. Especially when cutting on the neck, wrist, groin, and penis, Chinese kitchen knives often appear open or spindle-shaped.

For junior forensic doctors, a more brainless judgment can be that if the head, face and neck are cut, the wound is straight, the edge of the wound is neat, the angle is sharp, and the wound is about 5 to 7 centimeters long, then it is first presumed that a kitchen knife was used Dry.

In comparison, if the ax head is cut all the way in, the cut corner will be rectangular, and if one end is cut in, it will be triangular. Other types of common sharp objects are also summarized.

To make a judgment at this level, Jiang Yuan didn't even need to make a decision. The forensic report had already been listed.

Everyone nodded. Kitchen knives are easy to find, but for those who specialize in dismembering corpses, kitchen knives are definitely not the first choice to buy. In other words, if you use a kitchen knife to dismember the body, there is a high probability that you happen to have a kitchen knife on hand.

Ma Jiyang took another sip of tea and said slowly: "He took the things around him casually again - it shows that he didn't have a particularly detailed plan, but he did a pretty good job on the case. Is it luck? Or - ——Have a criminal record? ""

This speculation was a bit bold, but as soon as Jiang Yuan thought about it, he somewhat agreed with Ma Jiyang's point of view.

Although body parts have been found so far in this case, it has to be said that the murderer's operation was quite smooth.

The detectives who checked the surveillance did not find any usable evidence. The body parts were also cleaned up relatively cleanly, and the location for dumping the body was not bad. If the water level of the Taihe River had not risen, in ten days and a half, this body would have been buried. The condition will only get worse and harder to find.

As we all know, killing someone is like working on a project. There are few times when things go smoothly, but there are many times when you encounter difficulties. Many times they are insurmountable difficulties.

Therefore, when you see a project progressing very smoothly, you should not first think that the project is easy, but you should think that the person in charge of the project is capable, experienced and well-prepared.

Otherwise, any small mistake in the middle may cause the whole game to lose.

"It is indeed possible that he is a criminal. Otherwise, it would be impossible for most people to move the body three times." Jiang Yuan agreed.

Not only will the corpse become stinky, but its skin will also become pigmented and turn yellow. Rigor mortis is even more likely to make people feel sick.

A person who can resist throwing a corpse once is a helpless person. Throwing a corpse twice in a row must at least be very strong mentally. Many murderers will find their bodies hidden in their homes when they are caught.

It’s not that they don’t know how to dismember or dump corpses, it’s that the spiritual world of modern people is so far away from killing and corpses that many people can’t bear this kind of thing, even if they kill themselves.

Therefore, the possibility that the murderer can kill and dismember the body and dispose of the body twice without being discovered without sufficient preparation is indeed very likely to be a criminal.

"You can visit the ex-convicts nearby based on their addresses and see what's going on in their homes. His body was cut into pieces so finely, so he's probably living alone. Even so, the bathroom and other places are probably in a mess. , the sewer might be clogged,

There are also bone fragments and the like, you don’t know where they will splash——” Ma Jiyang immediately thought of a way.

Since it is speculated that the murderer dismembered the body at home, let's go and take a look.

Although the murderer must have been cleaned up, if you look at the scene, you might find something.

As for the workload, Ma Jiyang has not taken it into consideration for the time being. The case has been anxious for so long. If there is a clue, just get rid of it as soon as possible.

Jiang Yuan didn't object, maybe it was similar to what Ma Jiyang thought?

Maybe the object being visited will be revealed; maybe the visiting police officer will find clues; maybe the neighbor of the person being visited will suddenly come forward and say, there is something strange happening here recently...

‘Okay, then this clue will be followed up by the Ma Brigade. Is it enough to just bring people from your own team? "Unlike before, Jiang Yuan is now the leader and commander of the task force. The deployment of personnel can be decided at a single word. He only needs to synchronize a copy of the meeting minutes to Yu Wenshu afterwards.

Ma Jiyang thought for a while and responded: "A small-scale check should be enough."

Ma Jiyang's team has more than 30 people. If it is a large-scale investigation, it will definitely not be enough. There are also a few large-scale visits. This also shows that Jiang Yuan is not very optimistic about this clue, so he invested slightly less.

Of course, Jiang Yuan also used a question, so if Ma Jiyang is willing to take on greater responsibilities, he can naturally ask for more manpower. As the saying goes, the greater the responsibility, the greater the ability—·

Ma Jiyang did not mention it again. There are advantages and disadvantages to interviewing ex-convicts. At the very least, ex-convicts have much stronger anti-reconnaissance capabilities. Whether they can interview ex-convicts often depends on the ability of the criminal police themselves, so , simply increasing manpower does not necessarily increase the success rate.

"Where are we?" Cao Chujun next to him is the captain of the third brigade. He was one of the first captains of the Changyang City Criminal Police Detachment to come into contact with Jiang Yuan. However, because he was older, Yu Wenshu rarely sent him to Jiang Yuan.

Cao Chujun had been involved in the case this time and naturally followed him all the way. He didn't want Jiang Yuan to worry about his age.

So take the initiative to ask for instructions.

Jiang Yuan thought for a while and said: "I personally prefer to wait. Judging from the current evidence, I think the time of death can be revised. It was previously 28 to 42 days. Based on the date the body was found, it is equivalent to Between 8 and 22 days before the body was found, my guess is, 10.

Just go to 14. "

Not only Cao Chujun, but also the eyes of several criminal police officers present lit up.

With such a short span of time of death, many investigations become exponentially more difficult.

Of course, if the judgment of the time of death is wrong, then Jiang Yuan will definitely take the blame, not to mention losing face.

Several people became serious and Cao Chujun said: "Actually, it doesn't have to be strict within 4 days. This case has been delayed until now, and it is enough to be accurate within a week."

"There are many fly samples found at the scene, and there are many types. In fact, they are helpful in judging the time of death." Jiang Yuan paused here and then said: "The investigation continues in other directions. As for the Third Brigade, I think You can try to find a kitchen knife.”

"kitchen knife?"

Jiang Yuan nodded: "The murderer used a kitchen knife to cut the body into pieces. He cut the body into pieces so finely that the back of the kitchen knife was probably curled up. This means the body was severely decomposed. Otherwise, it should be obvious from the scars - In short, the murderer's home The blade of my kitchen knife is sharpened. There should be a certain chance that I need to buy a new kitchen knife. "

Cao Chujun hesitated for a moment and said: "We do not register the kitchen knives we buy in the city at the moment."

"Let's check online shopping first. We don't want to find the person directly. We should make a list first. If there is a list that overlaps with other investigation directions, we can then come to the door." Jiang Yuan said, and then said: "Continuously dump the body parts. The corpse must be very tired, and the murderer is most likely a male, and he is likely to shop online. "

Cao Chujun agreed.

Ma Jiyang smiled: "I just don't know what it feels like to cook in a kitchen that has just been dismembered!"
