Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 357
Yunzhou and Huangzhou are both in the south. This wave of business trips to Liangzhou City will last for ten and a half months without returning.

Besides, when the criminal investigation detachment goes on business trips, they rarely fly.

In many cases, the type of transportation used within the system is not determined based on the urgency of the work, but based on the level of the passengers.

As for the criminal investigation detachment, which is similar to Cheng Zihao's level, they can only take trains, and at most they can only sleep in hard sleepers or soft sleepers.

In fact, from an economic perspective, many air tickets are sometimes cheaper than train sleeper tickets.

However, it doesn't matter now. The mutilation case was a backlog from three years ago, and the urgency of the investigation does not lie in one or two days.

The two groups went directly home to pack some luggage and things and set off today.

"Pay attention to your methods, communicate more with local colleagues, and call anytime if you have any questions."

At the train station, Cheng Zihao was making his final confession.

"Brother Cheng, don't worry, we are not young, we promise to complete the task."

Cheng Zihao nodded. He brought these people out by himself, so he felt relieved.

Moreover, they were only following the case of Zhang Can's disappearance, so the danger was not that great.

But he should be more careful on his side. If Wang Jian is really the murderer, he may have killed more than one person.

According to the autopsy results of the corpse dismemberment case at that time, the other party was experienced and the method of dismemberment was relatively professional.

Dismembering a body is not only a physical job, but also a technical job.

The strength of human bones is much stronger than many people imagine. For example, the human skull can generally withstand a heavy bombardment of 200 kilograms to 500 kilograms.

In some murder cases, the murder method used by the murderer is to hit the skull with a blunt instrument to cause death.

Judging from the forensic autopsy results of corpses that died in this way, it is rare that one blow can cause death. Most of them are hit multiple times, 10 times, 20 times, or even more. common.

Although this method of knocking may cause some damage to the skull, what really causes death is the transmission of concussive force that causes damage to the brain in the skull and leads to death.

The damage to the skull itself was relatively minor.

This is true of the skull, but also of other bones.

The hardness of the bones means that the tools needed to dismember the body must be strong, otherwise they require superb skills.

Know how to follow the joints between bones and divide the body.

And this ability is commonly known as the Cook Ding Jie Niu.

The murderer in the corpse dismemberment case used the method of dicing and dismembering the cow to dismember the body. There was no damage to the bones caused by powerful tools such as axes and saws.

The murderer used some kind of knife to cut the corpse into pieces along the bones. Although the technique was not particularly familiar and there were many scratches on the cartilage, for ordinary people, it was definitely professional.

This kind of ability cannot be obtained by killing pigs and other slaughters. It is most likely accumulated from the experience of killing and dismembering many times.

After all, the structure of human bones is still different from that of pig bones.

It is impossible to say that the other party has a background in forensic medicine, because the techniques are relatively crude and cannot reach the level of professional learning.

While Cheng Zihao and others were wandering around on the train, Lu Chuan once again locked himself in the underground laboratory under investigation.

Lu Chuan not only had to separate more than thirty groups of superimposed shoe prints, but also compared them to finally determine which shoe prints were left on top and were more numerous.

This time, Lu Chuan used the graphics layering of image processing software. Because the weight and clarity of the footprints were different, it was very difficult and a careful job.

At the end of the day, Lu Chuan only completed less than ten groups of footprint analysis.

The progress of this work is slower than Lu Chuan expected yesterday. He originally thought that more than [-] sets of shoe prints could be analyzed in two to three days, but now it seems that it will only be possible in three to four days.

However, it doesn’t matter if it takes longer.There have been no new cases in the criminal investigation detachment in the past two days. Ren Qiang and Sun Jun are still working on the previous cases.

Although Lu Chuan gave direct clues and the suspect over there was also caught, the subsequent interrogation evidence was fixed and many processes still needed to be completed.

It doesn't take more than three or five days, and it's always busy over there.

At the same time, several of Cheng Zihao's subordinates also arrived in Yunzhou.

"Zhang Can went out to work when he was in his twenties. He didn't have a fixed place. He was in the south a few years ago and then went to the north. Anyway, he went wherever he could make money and where friends recommended him."

Zhang Can's wife and Zhang Can grew up in the same village. Zhang Can went out to work after getting married, and has been working outside these years.

"But he comes back every year near the Chinese New Year and stays at home for two months. He also has video calls with his children and me basically every day."

"But three years ago, he suddenly lost contact. He didn't answer his videos and couldn't be reached on the phone. Later, the phone was turned off and we never contacted him again."

"Then the police were called."

"Do you know where he worked and who he was with?"

"I heard it was in Tianzhou City, but I checked there and found nothing."

Tianzhou City?
"Did he tell you that he was going to work in Liangzhou City?"

"I think I mentioned it once, I can't remember clearly."

"Where's the man? Who did he go with?"

"When he was in Tianzhou, he was with people from our village. Then he suddenly separated. I inquired about it and it was said that he left with a man named Wang. No one in the village has seen him since."

"Is that person's name Wang Jian?"

"I don't know, I just know that my surname is Wang."

"Is the person from the village who worked with your husband that year still there? Can you take us to meet him?"

Huangzhou, Jianshe Road Police Station.

"Old Huang, this is Cheng Zihao, the leader of the Liangzhou City Criminal Investigation Detachment. He has something to investigate. You are most familiar with the community situation in our jurisdiction. Please introduce him."

"Okay, director, don't worry, Captain Cheng, hello, my name is Huang Jun, I'm in charge of the community work in the institute."

Lao Huang is indeed very old, over 50 years old.

Cheng Zihao heard from the director here that Lao Huang had worked at the Jianshe Road Police Station all his life, doing household registration work in the past. Later, when computers were introduced, he couldn't understand it, so he did community work.

"Brother Huang, I'm not a captain, just call me Xiao Cheng."

As he spoke, Cheng Zihao handed over the cigarette: "Brother Huang, I am here this time to find a person named Wang Jian. This is his information."

The household registration system is connected nationwide. Huang Jun first took the cigarette and then looked at Wang Jian's information.

"It turns out it's him. I know this guy."

know?

Cheng Zihao's eyes lit up: "Brother Huang, tell me, what's going on with this guy?"

"Wang Jian was born and raised here. His father used to be a security guard in a cotton spinning factory. We often interacted with each other, so we got to know each other."

"A few years ago, there was a fire in their house, and my father was burned to death inside. After that, Wang Jian went out to work and couldn't come back even once a year."
