Liu Jinghui followed Jiang Yuan to Liu Chengming's residence, a container house on a construction site.
Compared with ordinary houses, this kind of house transformed from a container is colder in winter and hotter in summer, and the area is smaller. Apart from the function of sleeping, there is basically no space for enjoyment.
Despite this, Liu Chengming's residence on the construction site is considered good. Because he is a skilled worker, he can live in a single room.
But just like this container house, Jiang Yuan's investigation was boring. Even after careful inspection, he could not find any useful clues.
The accompanying technician packed up the equipment and said, "Captain Jiang, do you want to move the contents back and check again?"
This is purely to give Jiang Yuan face. Even if he were replaced by an ordinary expert, he would never even think about such an investigation. The work of the Criminal Division is also endless. Every unit is pressing, and a lot of manpower and time are wasted here.
If it's gone, you have to find a way to make up for it elsewhere.
Jiang Yuan did not have such a strong appeal. He shook his head and said: "This is the temporary residence of the suspect. If you can't find evidence, consider other places."
"The suspect said he threw the knife into Dongxi Lake. Dai Zhi has organized people to search for it. However, Dongxi Lake is quite deep and there are underwater undercurrents, so it may not be easy to find it." From the technician's statement.
From a perspective, finding the knife used when committing the crime is the most important thing at the moment. Once the knife is found, the vehicle used when the crime was committed, and the corresponding photos are found, the evidence chain of this case will be relatively complete.
At this time, after a night of thinking, Liu Jinghui became more determined and said: "The credibility of Liu Chengming's confession is doubtful, and many testimonies cannot be falsified at present. At the very least, we have to find some objective evidence. As for the knife,
They just go find it.”
Different from ordinary homicide cases, Liu Chengming burned the two victims to ashes, so that the police could not directly extract evidence from the victims, how they killed, what weapons were used, etc. They could only listen to Liu Chengming's confession.
This is a model that Liu Jinghui dislikes very much. Naturally, he is unwilling to gain trust, let alone pay a huge price for it.
Jiang Yuan listened to Liu Jinghui's tone and asked, "Then what do you want to check?"
"Can I check whatever I want?" Liu Jinghui suddenly asked.
"Of course." Jiang Yuan gave an affirmative reply.
"I'm just thinking about it in my head, but I don't have any evidence in my hand." Liu Jinghui said.
"You haven't always been like this." Jiang Yuan glanced at Liu Jinghui strangely.
Liu Jinghui was suddenly moved. This is the meaning of the existence of the dragon knight. The dragon knight does not need any explanation. When the dragon gun points, the dragon will spray long flames and swoop away. How romantic this is.
The dragon knight controls the dragon, using his body as his body and his arms as his fingers, just like Watson in Sherlock Holmes.
"I think something is wrong with Liu Chengming. I have a key question. Was the skull of the male deceased burned away, or was the head cut off in advance?" Liu Jinghui asked.
Jiang Yuan had obviously considered this issue and said: "I think there is a high probability that it was cut off in advance. Although the possibility of being burned to ashes cannot be completely ruled out, this is too difficult and requires a large amount of combustion accelerant, and it must be kept at
Burn it in front of you. If it is burned in such an open environment in the wild, it is unlikely to be burned to ashes in one go. Looking at the final shape of the other bones, there must be remains of the skull of the male victim."
Liu Jinghui nodded: "If the murderer had been waiting and had time to take away the burned bone fragments from the male victim's skull, he should have taken away all the other burned bone fragments. In this case, this case may not be solved.
Already."
"You need to bring a lot of combustion accelerants, and you don't necessarily have to wait there for several hours. The disposal of the burned bone fragments is another problem. Bury them?"
"It's really possible that he cut off his head and buried it." Liu Jinghui expressed his thoughts and said: "I think we should give priority to finding the head. If the victim's head is found, it means that Liu Chengming lied and he will be given a death sentence.
.The specific facts of the case should also become clear.”
When a corpse is burned in a funeral parlor, diesel fuel is sprayed from all sides to support the combustion, and at the same time, the body's grease is used to burn it as fully as possible. Even so, at the end of the burn, a large number of lumpy bones will remain.
These bones are often smashed by the staff of the funeral home with a hammer, and then some are put into the customer's urn. It is impossible to put them all in, there are too many left, and ordinary urns do not have that big space.
Burning bones in the wild, even if diesel fuel is used to assist combustion, is unlikely to achieve such an effect. The most important thing is that the head should be the most resistant part to burning.
To completely burn it to ashes in such an environment, one needs to stand in front of it, repeatedly pour diesel, hit it with a hammer, etc. Only then can this be achieved.
Obviously, if the murderer was willing to go to this step, he could have picked up all the burned bone fragments or disposed of 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 explain the issue, it is actually more cost-effective to give a comprehensive and accurate explanation. Because this is one of the basis for mitigating the punishment, it is possible to
Escaped from execution immediately.
Liu Chengming admitted the circumstances of the murder, but failed to give a truthful and complete explanation. This was somewhat abnormal, indicating that he must be hiding something from the police. He also had no net worth and was not an official, which aroused Liu Jinghui's curiosity.
"Actually, there is another question." Liu Jinghui stood in the container house, sweating slightly on his face, and said: "The suspect Liu Chengming is an excavator. He actually has the conditions to bury the body deeply, and it doesn't cost anything.
If you have the strength to choose to burn the corpse, it’s actually a bit unnecessary.”
"Maybe it's because the excavator is not easy to move around." The technician who had been standing next to him said at this time: "As far as I know, many excavators nowadays, especially those with bosses, have very detailed data monitoring inside them.
In detail, some require a password to be turned on, and the location and time of the excavator at that time are all recorded clearly. The dynamics of the excavator are also recorded. If he secretly digs a hole to bury a body, the data on the excavator can be buried.
Got him."
Liu Jinghui nodded slowly: "This is indeed a possible factor. However, Liu Chengming has been driving an excavator for so long, so it shouldn't be difficult to find another excavator. You can borrow one or even rent one..."
"But he still chose to burn the body."
"There are many benefits to burning a corpse. If it is done well, it will be better than burying it with an excavator, and the traces will be smaller. If it weren't for you, it would be difficult to determine the identity of the victim. In addition, the excavator is relatively big after all. So
It is easy for people around to know about big movements. It is not easy to go to the wilderness, and it is also inconvenient to carry a body at the same time."
Several people nodded when they heard what Liu Jinghui said was clear and logical.
Liu Jinghui said at this time: "Let's check. First, ask people around Liu Chengming to see if he has borrowed or rented an excavator. Also check his address book and WeChat records. If it was rented normally, it should be
This is the only channel."
"Yes." Seeing that Liu Jinghui was sure, Wang Chuanxing immediately made arrangements.
This form of inquiry is a bit like an investigation, but much simpler and cheaper. It is at the police station or criminal police brigade level.
"As far as this case is concerned, we are actually a bit picky. However, I think Liu Chengming has another case on his back. There is a chance to dig deeper." Liu Jinghui said this in front of Jiang Yuan, but when Dai Mingsheng was present, he instead
Be hesitant.
The technician next to him became helpless, silently took out his mobile phone, and began to send a message 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. You can try to combine the cases. If Liu Chengming does it like this, he may be path dependent.
"
Connecting cases in parallel is the basic skill of the criminal police. There are not enough clues in one case, but when two cases are put together, the clues are suddenly enough. As for criminals, there are only a few criminals who can work on one case with peace of mind and not work on the second case.
Even the murderer is no exception.
This thing is like gambling. If you can earn several years and decades of income by guessing the size once, who can bear the loneliness and work peacefully? If killing one person can solve the problem that decades of income cannot solve,
, who can still have the patience to maintain a relationship?
After a few 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 room.
No matter what the disturbances are outside, the most basic technical work still needs to be done after all.
After the investigation of Liu Chengming's temporary residence was completed, Jiang Yuan took a walk around the construction site. After finding nothing else, he and Liu Jinghui returned to the criminal police detachment, set up a hot pot, and waited for reports from all aspects.
In the evening, new reports began to arrive one after another.
"There are no new clues. However, the car used by Liu Chengming was found. He rented a car in Xianyu..." Wang Chuanxing gave a brief explanation to Jiang Yuan and others.
Jian Louyuan also came over and said: "We haven't found any clues yet through digging machines and burning corpses."
Liu Jinghui nodded slowly.
Wei Shijun squeezed out like toothpaste from behind his captain and said, "Could it be that... Liu Chengming really has no old cases here?"
If the leader doesn't want to say anything, let the person who cares least say it.
Liu Jinghui just looked at him with a smile and said, "Then did Liu Chengming give a complete explanation?"
"No." This time it was Jian Louyuan who answered.
It is extremely difficult to justify a case, especially when considering the details. It is very difficult to lie and then try to justify it.
The criminal suspect has no right to choose the details that he does not describe. If he does not answer obediently, he will not state the truth.
"Then let's continue the trial." Liu Jinghui was not in a hurry at this time, and said to Jian Louyuan: "The person who burned the corpse can't be found. Then we can list another item, whether there are corpses abandoned at the construction site, or whether there are corpses buried in the future.
Solve murder cases. In this way, directly check the construction sites where Liu Chengming worked and the murder cases that occurred near the construction sites to see if there are any matches."
Jian Louyuan was quite puzzled: "Rabbits don't even eat the grass beside their nests. What's more, Liu Chengming burned his body so far away. Would he kill people at the construction site?"
"Perhaps it's because he didn't go well with killing people at the construction site. You can't teach others, but you can teach them once." Liu Jinghui's brain was running rapidly, and he said: "Liu Chengming, the excavator, has been working on the construction site for half his life.
, and ended up coercing people to kill and burn their bodies to hide their heads. The whole process went too smoothly. Let’s check first.”
