Chapter 1105: People Can’t Teach
The next day.
early morning.
Liu Jinghui followed Jiang Yuan to Liu Chengming's residence, a container house on a construction site.
Compared with ordinary houses, this type of house converted from containers is cold in winter and hot in summer, and is small in size. Apart from the function of sleeping, there is basically no space for enjoyment.
Despite this, Liu Chengming's residence is considered good on the construction site, because he is a technical worker, so he can live in a single room.
But Jiang Yuan found it boring to investigate such a container house. Even after a thorough investigation, he could not find any useful clues.
The accompanying technician packed up his equipment and said, "Captain Jiang, do you want to move the things inside back and check them again?"
This was purely to give Jiang Yuan face. Even if it was a more ordinary expert, such an investigation would not be possible. The Criminal Division had endless work to do. Every unit was urging them to do it. If too much manpower and time were wasted here, they had to find ways to make up for it elsewhere.
Jiang Yuan did not have such a strong appeal, and shook his head and said: "This is the suspect's temporary residence. If we can't find evidence, we can consider other places."
"The suspect said he threw the knife into Dongxi Lake. Dai Zhi has organized people to look for it. However, Dongxi Lake is quite deep and there are undercurrents underwater, so it may not be easy to find it." From the technician's point of view, finding the short knife used in the crime is the most important thing at the moment. If the knife is found, and then the means of transportation used in the crime and the corresponding photos are found, the chain of evidence in this case will be relatively complete.
At this time, after a night of thinking, Liu Jinghui became more determined and said, "Liu Chengming's confession is questionable, and many testimonies cannot be falsified at present. At the very least, we have to find some objective evidence. As for the knife, they can go find it."
Unlike ordinary homicide cases, Liu Chengming burned the two victims into ashes, making it impossible for the police to obtain evidence directly from the victims. They could only listen to Liu Chengming's confession to learn how he killed people, what weapon he used, etc. This was a model that Liu Jinghui really disliked. Naturally, he was unwilling to gain their trust, and even more unwilling to pay a huge price for it.
Jiang Yuan listened to Liu Jinghui's tone and asked, "So what do you want to check?"
"Can I check whatever I want?" Liu Jinghui suddenly asked.
"Of course." Jiang Yuan gave an affirmative answer.
"It's all in my mind. I don't have any evidence in my hands." Liu Jinghui said.
"You haven't always been like this." Jiang Yuan looked at Liu Jinghui strangely.
Liu Jinghui was suddenly moved. This was the meaning of the dragon knight's existence. The dragon knight did not need any explanation. Wherever the dragon spear pointed, the dragon would swoop down with long flames. How romantic it was.
The dragon rider rides the giant dragon, using his arms as if they were his body and his fingers as if they were his arms, like Watson under Sherlock Holmes.
"I think something is wrong with Liu Chengming. I have a key question: was the skull of the male deceased burned, or was his head cut off in advance?" Liu Jinghui asked.
Jiang Yuan had obviously considered this question, and said, "I think it was most likely cut off in advance. Although the possibility of burning to ash cannot be completely ruled out, it is too difficult. It requires a large amount of combustion aid, and you have to watch it burn right in front of you. It is unlikely to burn to ash in one go if it is burned openly in the wild. Judging from the final shape of the other bones, there must be some remains of the male victim's skull."
Liu Jinghui nodded: "If the murderer had been waiting in front of us and had time to take away the burnt bone fragments of the male victim's skull, he should have taken away the other burnt bone fragments. In this way, this case might not even exist."
"That requires a lot of combustion aid, and we may have to wait for several hours. The disposal of the burnt bone fragments is another problem. Bury them?"
"It is possible that he buried the severed head." Liu Jinghui expressed his thoughts, saying, "I think we should find the head first. If the victim's head is found, it means that Liu Chengming lied, and we can kill him immediately. The specific details of the case should also be clear."
When burning corpses in funeral homes, diesel is sprayed from all sides to help the combustion, and the fat of the corpse is used to burn as fully as possible. Even so, at the end of the burning, there will still be a lot of lumps of bones left.
These bones are often smashed with hammers by the funeral home staff, and then some are put into the client's urn. It is impossible to put all of them in, because there are too many left, and the general urn does not have enough space.
Burning bones in the wild, even with diesel fuel, is unlikely to achieve such an effect. Most importantly, the head should be the most resistant part to burning.
In order to completely burn it to ashes in such an environment, one needs to stand in front of it, pour diesel repeatedly, hit it with a hammer, etc., before it can be achieved.
Obviously, if the murderer was willing to do this, he could just pick up all the burnt bone fragments or deal with them accordingly.
Analyzed from this perspective, Liu Chengming's testimony is untrue.
This is also one of the reasons for Liu Jinghui's suspicion. As a murder suspect who has been arrested, since he has chosen to confess, it is actually more cost-effective to confess comprehensively and accurately. Because this is one of the grounds for reducing the punishment, it is possible to escape from the immediate execution of the death penalty.
Liu Chengming admitted to the murder but did not give a complete and truthful account, which was somewhat abnormal, indicating that he must be hiding something from the police. He had no wealth and was not an official, which aroused Liu Jinghui's curiosity.
"There is actually another question." Liu Jinghui stood in the container room, sweating slightly on his face, and said, "The suspect Liu Chengming was an excavator operator. He actually had the conditions to bury the body deep without much effort. Choosing to burn the body is actually a bit unnecessary."
"Maybe it's because the excavator is not easy to move around." The technician who had been standing nearby said at this time: "As far as I know. Many excavators now, especially those owned by bosses, have very detailed data monitoring. Some require a password to start up. The location and time of the excavator are all recorded clearly. The movement of the excavator bucket is also the same. If he secretly digs a pit to bury the body, the data on the excavator can bury him."
Liu Jinghui nodded slowly: "This is indeed a possible factor. However, Liu Chengming has been driving an excavator for such a long time, it should not be difficult to find another one. He can borrow one or even rent one..."
"But he still chose to burn the body."
"There are many advantages to burning bodies. If handled properly, it's better than burying them with an excavator. It will leave fewer traces. If it's not you, it would be difficult to identify the victim even if they find him. In addition, an excavator is large after all. With such a loud noise, it's easy for people around to know. It's not easy to go to the wilderness, and it's not convenient to carry the body with you."
After listening to Liu Jinghui's clear and logical explanation, several people nodded.
Liu Jinghui said at this time: "Let's check it out. Let's ask people around Liu Chengming to see if he has borrowed or rented an excavator. Check his address book and WeChat records as well. If it was a normal rental, this should be the only channel."
"Yes." Seeing that Liu Jinghui had confirmed it, Wang Chuanxing immediately made arrangements.
This form of questioning is a bit like an investigation, but it is much simpler and cheaper. It is at the level of a police station or criminal police brigade.
"As far as this case is concerned, we are actually a bit nitpicking. However, I think Liu Chengming is still involved in another case, and there may be a chance if we dig deeper." Liu Jinghui said this in front of Jiang Yuan. If Dai Mingsheng was present, he would have hesitated.
The technician next to him became helpless, silently took out his cell phone and started sending messages to the detachment leader.
Liu Jinghui watched him send the message, and then said to Wang Chuanxing: "Check the previous corpse burning cases to see if there are any similar cases. We can try to combine the cases. If Liu Chengming does this, it may be path dependence."
Linking cases is a basic skill for criminal police. If the clues of one case are not enough, the clues of two cases together are suddenly enough. However, there are only a few criminals who can concentrate on one case and not commit a second case. Even murderers are no exception.
This is like gambling. If you can earn several years or decades of income by guessing the size once, who can bear the loneliness and work at ease? If killing a person can solve a conflict that decades of income cannot solve, who can bear the patience to maintain the relationship?
After a few phone calls were made, the Lanyue City Criminal Police Detachment immediately took action.
Jiang Yuan put on his mask again and collected the evidence in the container house.
No matter what troubles there are outside, the most basic technical work still needs to be done.
After completing the survey of Liu Chengming's temporary residence, Jiang Yuan took a walk around the construction site. After finding nothing else, he returned to the Criminal Police Detachment with Liu Jinghui, set up a hot pot, and waited for reports from all parties.
By the evening, new reports began to arrive.
"There are no new clues. However, the car used by Liu Chengming was found. He rented a car on Xianyu..." Wang Chuanxing gave a brief explanation to Jiang Yuan and others.
Jian Louyuan also came over and said, "The excavators and the cremation of the bodies have not yet found any clues."
Liu Jinghui nodded slowly.
Wei Shijian squeezed out from behind his captain like toothpaste and asked, "Could it be that... Liu Chengming really has no old cases?"
If the leader is reluctant to say something, let the person who cares the least say it.
Liu Jinghui just smiled at him and said, "Did Liu Chengming give a complete account?"
"No." This time it was Jian Louyuan who answered.
It is extremely difficult to justify a case, especially when it comes to details. It is very difficult to tell a lie and then make it up.
The suspect has no right to choose not to describe the details. If he does not answer, he is not telling the truth.
"Then let's continue the investigation." Liu Jinghui was not in a hurry at this time, and said to Jian Louyuan: "If we can't find the body burned, then we can list another item, whether there are unsolved murders of bodies abandoned or buried at construction sites. In this way, we can directly check the construction sites where Liu Chengming has worked and the murders that occurred near the construction sites to see if there are any matches."
Jian Louyuan was quite confused: "Even rabbits don't eat grass near their burrows. Besides, Liu Chengming burned the bodies so far away. Would he kill people at a construction site?"
"Maybe it's because he didn't have a smooth time killing people at the construction site. People can't teach people, but things can teach people once they are taught." Liu Jinghui's brain was working rapidly, and he said, "Liu Chengming is an excavator driver. He has worked on construction sites for half his life. In the end, he was forced to kill people and burned the bodies and hid the heads. The whole process was too smooth. Let's check it out first."
