Chapter 965 Kitchen Knife
"Yes, why? The murderer is somewhat ill."
Sitting in the small conference room, several members of the task force flipped through the updated information and re-read the various pictures provided by Jiang Yuan, and then threw away the files containing the explosive amount of maggots.
"Are the murderer and the body dumper two people? The murderer killed someone at the first scene and dumped the body at the second scene. The people at the second scene found the body. For some reason, they may not be able to call the police, so they dumped the body again?"
The speaker was the captain Ma Jiyang, the ceiling of the Changyang City Criminal Police Detachment. He has won three second-class merits and investigated countless major cases. Naturally, he is rich in experience. After seeing Jiang Yuan's report, he immediately gave a reasonable guess.
Jiang Yuan shook his head slowly and said, "The time between the second and third dumpings is relatively short, and the environment is relatively good. Otherwise, the body would have laid a lot of eggs when it was dumped for the second time, and the difference in flies would be greater when it was dumped for the third time."
Ma Jiyang thought about it and said, "Then change it. The murderer did it independently. He killed the person at the first scene and dumped the body at the second scene. For some reason, he quickly moved to the third scene. It is estimated that a single person must be exhausted to dump the body twice independently. This can also explain why he dumped the body by the river instead of digging a pit to bury it."
This speculation can be regarded as a correction to the question Jiang Yuan just raised.
Jiang Yuan did not comment. It is indeed possible.
With Ma Jiyang's previous experience, someone immediately proposed a new idea:
'It is very likely that the environment of the second scene was too complicated, or something happened, so it was immediately moved to the third scene. As for the woven bag, it should have been obtained at the second scene. Will the remaining body parts still be at the second scene? "
"It's not easy to dump the body again, especially with so many body parts. If I do it alone, the workload is almost the same as moving house once, and I have to clean up the second scene. It's better to dig a hole."
"Digging a hole is not necessarily more useful than dumping the body. I tend to think it's functional. It's very likely that there was a reason to move the first scene, which was a public place not controlled by the murderer, or the victim's place. It was hastily moved to the second place, which is likely to be a place where the murderer feels safe, such as his own home. Then, he found a place to dump the body here and dismembered the body at the same time. "
Jiang Yuan nodded when he heard this and said, "Judging from the chopping marks on the house, the knife used to divide the house is likely to be a Chinese kitchen knife.
Therefore, it is very likely that the second scene is the murderer dismembering the body at home. "
The domestic forensic research on kitchen knives has been very detailed. First of all, kitchen knives are heavy handle sharp weapons, but compared with similar heavy handle sharp weapons, kitchen knives often cut longer and deeper. Especially when cutting the neck, wrist, groin, and penis, Chinese kitchen knives often appear in a splayed or spindle shape.
For junior forensic doctors, a more brainless judgment can be that if the head, face, and neck are cut, the wound is straight, the wound edges are neat, the wound angles are sharp, and the wound is exactly about 5 to 7 cm long, then it is presumed that it was done with a kitchen knife.
In contrast, if the axe is completely If you cut into it, the corner is rectangular, and if you cut into one end, it is triangular. There are also summaries for other common sharp tools.
Jiang Yuan doesn't need to make judgments at this level, as the forensic report has already listed them.
Everyone nodded. Kitchen knives are easy to find, but people who specialize in dismembering bodies will definitely not buy kitchen knives first. In other words, if someone dismembers a body with a kitchen knife, there is a high probability that they just happen to have a kitchen knife at hand.
Ma Jiyang took another sip of tea and said slowly: "He just used whatever he had around him - it shows that he didn't have a particularly detailed plan, but he did a good job on the case. Is it luck? Or - has he a criminal record?" "
This speculation is a bit bold, but Jiang Yuan turned his mind and agreed with Ma Jiyang's point of view.
Although only body parts have been found in this case so far, it must be said that the murderer's operation is still quite smooth.
Not only did the criminal police who checked the surveillance find no usable evidence, but the body parts were also cleaned up relatively cleanly, and the location where the body was thrown was also good. If the water level of the Taihe River had not risen, the state of the body would have been even worse and harder to find in ten days or half a month.
As we all know, killing is like doing a special project. There are few times when it is smooth and there are many times when you encounter difficulties, and many times they are insurmountable difficulties.
Therefore, when you see a special project progressing very smoothly, you can't first think that the special project is easy, but you should think that the person in charge of the special project is capable, experienced, and well prepared.
Otherwise, any small mistake in the middle may lead to a complete failure.
"It is indeed possible that he is a criminal. Otherwise, it would be impossible for ordinary people to move the body three times." Jiang Yuan agreed.
The body will not only become smelly, but its skin will also be pigmented and turn yellow. Lividity and rigor mortis are even more disgusting.
Those who can resist throwing the body once are people who have no choice. To throw the body twice in a row, at least you have to be very strong in your heart. Many murderers were found to have their bodies hidden in their homes when they were caught.
It's not that they don't know how to dismember or dispose of bodies, but that the spiritual world of modern people is too far away from killing and corpses, so many people can't bear such things, even if they killed the person themselves.
Therefore, the murderer who can dismember and dispose of the body of a person without being fully prepared is very likely to have a criminal record.
"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 reveal something; maybe the police officer who visited 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 questions, 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.
It's ok until 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 overlap with the list of 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!"
