Chapter 947

"Yeah, why? This killer is somewhat sick."

Sitting in the small meeting room, several special task force members flipped through the updated information, reread the various pictures provided by Jiang Yuan, and threw these case files that were explosive in maggot content far away.

"The killer and the corpse disposer are two people? The killer killed someone at the first scene, disposed of the corpse to the second scene, and the people at the second scene discovered the corpse. Because of some reason, they might not be able to report to the police, so they disposed of the corpse again?"

The speaker is Captain Ma Jiyang, the meritorious ceiling of the Changyang Municipal Criminal Investigation Detachment, who has accumulated three second-class merits and investigated countless major cases. With rich experience, seeing Jiang Yuan's report, he immediately gave a reasonable speculation.

Jiang Yuan shook his head slowly and said: "The time between the second corpse disposal and the third scene is relatively short, and the environment is relatively good. Otherwise, if the corpse was laid many eggs at the second scene, the difference in flies at the third scene would be greater."

Ma Jiyang thought about the matter and said: "Then change it. The killer completed it independently, killed someone at the first scene, disposed of the corpse to the second scene, and because of some reason, quickly transferred to the third scene. Completing two corpse disposals independently, it is estimated that he is also tired enough. This can also explain why he disposed of the corpse by the river instead of digging a pit to bury it."

This speculation can be considered as a correction of the problem just raised by Jiang Yuan.

Jiang Yuan did not express his position, there is indeed such a possibility.

With Ma Jiyang's car in front, someone immediately put forward new ideas:

"It is very likely that the environment of the second scene was too complicated, or some changes happened, so it was immediately transferred to the third scene. As for the woven bags, they should have been obtained at the second scene, right? Will the remaining corpse pieces still be at the second scene?"

"Re-disposing the corpse once is not easy, especially so many corpse pieces. If one person does it, the workload is about the same as my moving, and I have to clean up the second scene, it is not as good as digging a pit."

"Digging a pit is not necessarily more useful than disposing of the corpse. I tend to be functional. It is very likely that the first scene has a reason that must be transferred. It is a public place that is not controlled by the killer, or the victim's place. Hurriedly transferred to the second location, the second location is very likely the place where the killer feels safe, such as his own home, and then, he found a place to dispose of the corpse here, and synchronized the dismemberment and other operations."

Jiang Yuan nodded when he heard this, and said: "Judging from the chopping marks on the corpse, it is very likely that Chinese kitchen knives were used for dismemberment. Therefore, it is very likely that the second scene is the killer dismembering the corpse at home."

The research on murder weapons like kitchen knives has been very detailed by domestic forensic doctors. First of all, a kitchen knife is a sharp weapon with a large weight and a handle, but compared with similar large-weight sharp weapons with handles, the cutting wounds of kitchen knives are often longer, and the wound base is also deeper. Especially when cutting on the neck, wrist, groin, and Ding Ding, Chinese kitchen knives often appear in the shape of a 'duo' or spindle.

For junior forensic doctors, a more brainless judgment can be that if there are chopping wounds on the head, face, and neck, the wound is straight, the wound edge is neat, the wound angle is sharp, and the wound is exactly about 5 to 7 centimeters long, then first presume it was done with a kitchen knife.

In contrast, if an axe is chopped in completely, the wound angle is rectangular, and if one end is chopped in, it is triangular. Other common sharp weapons also have their own summaries.

This level of judgment does not need Jiang Yuan to go out at all, and there are already forensic reports listed.

Everyone nodded one after another. Kitchen knives are easy to find, but people who specialize in dismembering corpses, the first choice to buy is definitely not a kitchen knife. In other words, those who use kitchen knives to dismember corpses are likely to have kitchen knives at hand.

Ma Jiyang drank tea again and said slowly: "It is taking things around you again... indicating that he does not have a particularly detailed plan, but the case is done quite well. Is it luck? Or... has a criminal record?"

This speculation is slightly bold, but Jiang Yuan turned it in his mind and agreed with Ma Jiyang's point of view.

Although this case has only found corpse pieces so far, it must be said that the killer's operation is still quite smooth.

The criminal investigators who checked the monitoring did not find usable evidence, and the corpse pieces were cleaned relatively cleanly, and the place where the corpse was disposed of was also good. If it weren't for the rise of the Taihe water level, after another ten days and a half months, the state of this corpse would only be worse and harder to find.

As everyone knows, murder is like doing a project. There are few times when it is smooth, and there are many times when difficulties are encountered. Many times, they are insurmountable difficulties.

Therefore, when seeing a project advancing very smoothly, one should not first think that the project is easy, but should think that the project manager has ability and experience, and is well prepared.

Otherwise, any small loophole in the middle may lead to a total loss.

"It is indeed possible to be a person with a criminal record. Otherwise, transferring the corpse twice, and having to dismember the corpse in the middle, ordinary people can't do it." Jiang Yuan expressed agreement.

The corpse will not only smell, but its skin will also be pigmented, turning yellow. Corpse spots and corpse stiffness are even more likely to make people feel disgusted.

People who can endure disposing of the corpse once are those who have no way, and disposing of the corpse twice in a row, at least the heart must be very strong. Many murder killers are caught, and it will be found that the corpse is hidden in their own home.

It is not that they will not dismember the corpse, will not dispose of the corpse, but that the spiritual world of modern people is too far away from killing and corpses, so that many people cannot bear this kind of thing, even if the person was killed by themselves.

Therefore, a killer who can kill, dismember, and dispose of the corpse twice without being discovered under the premise of insufficient preparation, the possibility of a person with a criminal record is indeed very high.

"You can visit the people with criminal records nearby according to the address, and see the situation in their homes. He dismembered the corpse so finely, it is very likely that he lives alone. Even so, places like the bathroom are estimated to be a mess, and the sewer may be blocked, and there are broken bone fragments and so on, you don't know where it will splash..." Ma Jiyang immediately thought of a method.

Since it is guessed that the killer dismembered the corpse at home, let's go and see.

Although it is said that the killer must have cleaned it up, looking at the scene, it is possible to find something.

As for the workload, Ma Jiyang did not consider it for the time being. The case has been stuck for so long, and if there is a clue, hurry up and use the iron feet.

Jiang Yuan did not oppose it, and thought about the same as Ma Jiyang—what if?

What if, the visited object reveals a horse's foot; what if, the visiting police officer finds a clue; what if, the neighbor of the visited person suddenly stands up and says, we have a strange thing here recently...

"Okay, then this line of clues will be followed up by Team Leader Ma. Just take your own team, is it enough?" Unlike before, Jiang Yuan is now the person in charge and commander of the special task force. Personnel dispatch is decided in one word, and only need to synchronize a copy of the meeting minutes to Yu Wenshu afterwards.

Ma Jiyang thought about it and agreed: "Small-scale check, it should be enough."

Ma Jiyang's brigade has more than 30 people. If it is a large-scale screening, it is definitely not enough, and large-scale visits are also a bit less. And this also shows that Jiang Yuan is not very optimistic about this line of clues, so the investment is slightly less.

Of course, Jiang Yuan also used a question, so if Ma Jiyang is willing to take greater responsibility, he can naturally ask for more manpower. It is the so-called greater responsibility, greater ability...

Ma Jiyang did not bring it up again. Visiting people with criminal records has advantages and disadvantages. At the very least, the anti-reconnaissance ability of people with criminal records is much stronger, so whether it can be visited often depends on the ability of the criminal investigators themselves. Therefore, simply increasing manpower does not necessarily increase the success rate.

"What about us?" The person next to him is Cao Chujun, the captain of the Third Brigade. He is one of the captains of the Changyang Municipal Criminal Investigation Detachment who first came into contact with Jiang Yuan, but he is older, and Yu Wenshu rarely sent him to Jiang Yuan's side.

This case was contacted by Cao Chujun very early, and naturally followed all the way. He didn't want Jiang Yuan to worry about his age, so he asked for instructions.

Jiang Yuan thought for a while and said: "I personally tend to wait. Judging from the current evidence, I think the time of death can be revised. Before it was 28 to 42 days. Based on the day of the discovery of the corpse, it is equivalent to 8 to 22 days before the discovery of the corpse. My judgment, 10 to 14 is enough."

Not only Cao Chujun, but several criminal investigators present had their eyes lit up.

If the span of the time of death is so short, the difficulty of many investigations is reduced exponentially.

Of course, if the judgment of the time of death is wrong, Jiang Yuan will definitely have to carry the pot, and losing face is even more unnecessary.

Several people became serious. Cao Chujun said: "In fact, it doesn't have to be strictly within 4 days. This case has been dragged to now, and it is very good to be accurate within a week."

"There are many fly samples found at the scene, and there are many types, which is actually conducive to judging the time of death." Jiang Yuan stopped here and added: "Continue the investigation in other directions. As for the Third Brigade, I think you can try to find a kitchen knife."

"Kitchen knife?"

Jiang Yuan nodded: "The killer used a kitchen knife to dismember the corpse, and dismembered it so finely, the kitchen knife is estimated to be curled after the back, which is also the reason why the corpse is relatively decayed, otherwise, it should be seen from the wound... In short, the kitchen knife in the killer's home is curled, and there should be a certain probability of buying a kitchen knife again."

Cao Chujun hesitated and said: "Buying a kitchen knife in our city is not registered at present."

"Check online shopping first. Don't ask to check directly to the person, first list a list, and those who overlap with other investigation directions, then go to the door." Jiang Yuan said, and added: "Continuous corpse disposal and dismemberment should be very tired, plus the killer is likely to be male, and it is very likely to shop online."

Cao Chujun agreed.

Ma Jiyang laughed: "I just don't know, what does it feel like to cook in a kitchen that has just been dismembered!"
