Chapter 965 Kitchen Knife
"Yes, why? This murderer is somewhat seriously ill."
Sitting in the small conference room, several members of the task force looked through the updated information and re-read the various pictures provided by Jiang Yuan, then threw away the files containing the maggot explosion.
"The murderer and the person who dumped the body are two different people? The murderer killed someone at the first scene and dumped the body at the second scene. People at the second scene found the body, but for some reason, they probably couldn't call the police, so they dumped the body again?"
The speaker was the captain Ma Jiyang, the top meritorious officer of the Changyang City Criminal Police Detachment. He had won three second-class merits and had investigated countless major cases. He was naturally experienced. 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 dumping of the body and the third scene was relatively short, and the environment was relatively good. Otherwise, the body would have laid a lot of eggs at the second scene, and the difference in flies would be even greater at the third scene."
Ma Jiyang thought about it objectively and said, "Then change it. The murderer acted 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 must be very tiring for a single person to dump the body twice independently. This can also explain why he dumped the body by the river instead of digging a hole to bury it."
This speculation can be regarded as a correction to the question just raised by Jiang Yuan.
Jiang Yuan did not comment, it was indeed a possibility.
With Ma Jiyang's experience as a lesson, someone immediately proposed a new idea:
"It is very likely that the environment at the second scene was too complicated, or something unexpected happened, so they immediately moved to the third scene. As for the woven bag, it should have been obtained at the second scene. Are the remaining body parts still at the second scene?"
"It's not easy to dump the body again, especially with so many body parts. If one person does it, it's almost the same amount of work as moving house. And we have to clean up the second scene. It's even worse than digging a hole."
"Digging a grave is not necessarily more useful than dumping the body. I tend to think it's more functional. It's possible that the first scene had to be moved for a reason, to a public place not controlled by the murderer, or to the victim's place. The second place was hastily moved to a place where the murderer felt safe, such as his own home. Then, he found a place to dump the body here and dismembered it at the same time."
Jiang Yuan nodded when he heard this and said, "Judging from the chopping marks on the body, a Chinese kitchen knife was most likely used to dismember the body. Therefore, it is very likely that the second scene was that the murderer dismembered the body at home."
Domestic forensic research on kitchen knives has been very detailed. First of all, kitchen knives are heavy handle sharps, but compared with similar heavy handle sharps, kitchen knives often leave longer and deeper wounds. Especially when cutting the neck, wrist, groin, and penis, Chinese kitchen knives often leave a splayed or spindle-shaped wound.
For a junior forensic doctor, a more brainless judgment would be that if there are cuts on the head, face, and neck, the wounds are straight, the wound edges are neat, the wound corners are sharp, and the wound is exactly about 5 to 7 centimeters long, then it can be presumed that the wound was caused by a kitchen knife.
In contrast, if the axe is fully inserted, the cut is rectangular, and if one end is inserted, the cut is triangular. There are also summaries of other common sharp tools.
Jiang Yuan didn't even need to make a judgment at this level, as the forensic report had already listed it.
Everyone nodded. Kitchen knives are easy to find, but people who specialize in dismembering bodies would definitely not buy kitchen knives first. In other words, if someone uses a kitchen knife to dismember a body, it is likely 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 was around him... This shows that he didn't have a particularly detailed plan, but he did a pretty good job on the case. Was it luck? Or... did he have a criminal record?"
This speculation is a bit bold, but Jiang Yuan thought about it 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 was quite smooth.
Not only did the detectives who checked the surveillance footage find no usable evidence, but the body parts were also cleaned up relatively cleanly and the location where the body was dumped was also good. If it weren't for the rising water level of the Taihe River, the body would have been in even worse condition and more difficult to find in another ten days or half a month.
As we all know, killing someone is like doing a project. There are few times when it goes smoothly, but there are many times when you encounter difficulties, and many of the times the difficulties are insurmountable.
Therefore, when you see a project progressing very smoothly, you should not first assume that the project has become easy. Instead, you should assume that the project leader is capable, experienced, and well prepared.
Otherwise, any small mistake in the process may lead to a complete failure.
"It is indeed possible that he is a criminal. Otherwise the body would have to be transferred in two times and dismembered in between. Most people cannot do that." Jiang Yuan agreed.
Not only does the corpse stink, but its skin also becomes pigmented and turns yellow. Rigor mortis is even more disgusting.
Those who can resist dumping the body once are helpless. To dump the body twice in a row, at least one must be very strong. Many murderers are found to have hidden bodies in their homes when they are 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 much so that many people cannot bear such a thing, even if they killed the person themselves.
Therefore, the possibility that the murderer, who was able to kill, dismember and dispose of the body again without being discovered without being fully prepared, was a person with a criminal record is indeed very high.
“We can visit all the people with criminal records nearby according to the address and take a look at the conditions at their homes. He cut the body into such small pieces that it’s very likely that he lives alone. Even if that’s the case, places like the bathroom are probably a mess, the sewer might be blocked, and there’re broken bones and the like, you don’t know where they’ll splash…” Ma Jiyang immediately thought of an idea.
Since we guessed that the murderer dismembered the body at home, let's go and take a look.
Although the murderer must have cleaned up the place, if we take a look at the scene, we might find something.
As for the workload, Ma Jiyang has not taken it into consideration for the time being. The case has been stuck for so long, so he would just take action as soon as he has a clue.
Jiang Yuan didn't object, and his idea was similar to Ma Jiyang's - maybe?
Who knows, the person being visited might reveal something; who knows, the visiting police officer might find some clues; who knows, the neighbor of the person being visited might suddenly come forward and say, “There’s something strange going on here recently…”
"Okay, then Captain Ma will follow up on this clue. Just bring the people from your team, is that enough?" Unlike before, Jiang Yuan is now the person in charge and commander of the task force. Personnel deployment is decided by his word, and he only needs to sync a copy of the meeting minutes to Yu Wenshu afterwards.
Ma Jiyang thought about it for a while and agreed: "A small-scale investigation should be enough."
Ma Jiyang's team has more than 30 people, which is definitely not enough for a large-scale investigation. Large-scale visits are also a bit too few. This also shows that Jiang Yuan is not very optimistic about this clue, so he invested 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 bring it up again. Visiting criminals with previous criminal records has advantages and disadvantages. At the very least, criminals with previous criminal records have much stronger anti-detection capabilities. Whether they can be visited often depends on the ability of the criminal police themselves. Therefore, simply increasing the number of staff will not necessarily increase the success rate.
"What about us?" Cao Chujun next to him was the captain of the Third Brigade. He was one of the first captains of the Changyang City Criminal Police Brigade to come into contact with Jiang Yuan, but because of his age, Yu Wenshu rarely sent him to Jiang Yuan's side.
Cao Chujun had been involved in this case very early on, so he naturally followed it all the way. He didn't want Jiang Yuan to worry about his age, so he took the initiative to ask for instructions.
Jiang Yuan thought for a moment and said, "I personally tend to wait. Based on 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 8 to 22 days before the body was found. In my opinion, 10 to 14 days will be enough."
Not only Cao Chujun, but also several criminal police officers present had their eyes lit up.
When the time span of death is so short, the difficulty of many investigations decreases exponentially.
Of course, if the judgment of the time of death was wrong, Jiang Yuan would definitely be blamed, not to mention the loss of face.
Several people became serious. Cao Chujun said, "Actually, it doesn't have to be strict to within 4 days. This case has dragged on until now, so it's good enough to be accurate within a week."
"There are a lot of fly samples found at the scene, and there are many types, which is actually helpful in determining the time of death." Jiang Yuan paused here and said, "Continue the investigation in other directions. As for the Third Brigade, I think we can try to find the kitchen knife."
"kitchen knife?"
Jiang Yuan nodded: "The murderer used a kitchen knife to cut the body into small pieces. The back of the knife must have been bent. This is because the body was severely decomposed. Otherwise, it would be obvious from the wounds... In short, the murderer's kitchen knife was bent. There is a certain probability that he needs to buy a new one."
Cao Chujun hesitated for a moment and said, "Currently, we don't register when we buy kitchen knives in our city."
"Let's check online purchases first. We don't need to find the person directly. Let's make a list first. If there is any overlap with the list in other investigation directions, we will go to the door." Jiang Yuan said, and then said: "The continuous dumping of bodies and dismemberment must be very tiring. In addition, the murderer is most likely a male, so he is likely to shop online."
Cao Chujun agreed.
Ma Jiyang smiled and said, "I just don't know what it feels like to cook in a kitchen where a body has just been dismembered!"
