National Forensic Doctor

Huang Qiangmin received the news and quickly came to Zouma Road Police Station.

Although it is an old one, it is still a new one.

Later, Director Chai also came to the Zouma Road Police Station and watched the interrogation of the criminal suspect An Zhiqiang.

"What are you going to do?" Director Chai listened and asked Jiang Yuan directly.

He is about to be transferred, and he doesn't want to deal with Ningtai County's affairs anymore. There were many people paying attention to Jiang Yuan, and some of them were quite high-level. Chai Tong felt he couldn't afford to offend them, but he could afford to hide them.

Seeing this, Huang Qiangmin took the initiative to end the conversation and said: "I think we can do some investigation first, especially the identity of the victim, to see if anyone was missing during that time, and if there is any relationship between the two suspects."

Everyone in the conference room nodded.

Jiang Yuan then added: "I think we can investigate the bathroom mentioned by An Zhiqiang. If it is the bathroom where the bodies were separated, there may still be evidence left."

As we all know, a bathroom where corpses have been separated is very difficult to clean.

A clean bathroom is likely to have traces of strong cleaning left behind. Although this is not enough to be used as evidence in court, it can be used as evidence during the investigation.

At the very least, if traces of aggressive cleaning are found, that would be a reason to engage in aggressive investigation mode.

However, the dismemberment happened six years ago. After six years of use, even if there are traces left in the bathroom, they are very small. There is still a high possibility that nothing can be found...

Huang Qiangmin said: "Let's investigate secretly. Keep the two suspects under surveillance. If necessary, move them away."

He wanted to see the investigation results before deciding whether to arrest someone.

"Okay." Jiang Yuan agreed immediately. The secret investigation does not affect his operations, the focus is still on the results of the investigation.

Huang Qiangmin immediately organized a team of people to go to the crime scene.

…

An Zhiqiang and his mother Zhang Yi live in an old community in the center of Ningtai. The community has a history of 20 years. It is an old six-story building without an elevator. Zhang Yi's house is on the fifth floor.

Seeing this building, Jiang Yuan first had an idea and said: "I'm afraid the first scene of the murder is also inside."

Several police officers nearby nodded in agreement.

What kind of behavior is it to move a body to the fifth floor and then dismember it when there is no elevator? I am purely a fitness trainer. I have nothing to do after I eat but exercise my muscles.

Most of the people who dismember bodies in old communities like this are forced to dismember the bodies because they cannot move the bodies away.

If the bad guy index of killing people and dismembering their bodies is 10, this one is usually a 5, which is equivalent to two Michelin stars.

"Hello, Ms. Zhang Yi? Are you at home? There is express delivery." Liu Wenkai next to him found a mobile phone and called Zhang Yi.

After saying a few words, Liu Wenkai put down his phone and said, "I'm at home."

"Tune the tiger away from the mountain." Jiang Yuan said that he would follow the established plan.

Liu Wenkai then called the police station and asked them to notify Zhang Yi that her son had been arrested.

Putting away his cell phone, Liu Wenkai added: "We still don't know how many people there are in Zhang Yi's family. The murderer's accomplice, Li Gan, went to work. The two of them lived together without a certificate."

Liu Wenkai had done research before.

Jiang Yuan nodded, and several people stayed in the car, waiting for changes upstairs.

Not long after, Zhang Yi was seen wearing sportswear, running out of the house quickly, riding an electric bicycle in the direction of the Zouma Road Police Station.

Needless to say, this is effective in driving the tiger away from the mountain.

Jiang Yuan took Wang Zhong and Mu Zhiyang upstairs.

The main survey location is a bathroom, and it is an old-fashioned bathroom with a total area of ​​only six or seven square meters. If there are too many people, I am afraid that they will not be able to move around.

However, we still had to be careful about other people in the room, so we took Mu Zhiyang with us to take the photos. To prevent the two trace inspectors from being slapped with a sap while they were working with their heads down.

He opened the door with his oil-stealing son's key, and entered a narrow living room with a three-piece sofa, coffee table, and TV. Next to it is an enclosed balcony.

Jiang Yuan stopped and observed in the living room. Considering the structure of this room, it was the most convenient to kill people in the living room.

Mu Zhiyang held an electric baton and checked the two bedrooms and one living room again. He looked through the closet but could not find the hidden man or woman. Then he took out the camera and started filming.

Jiang Yuan and Wang Zhong entered the bathroom and began to draw a grid to check.

The bathroom that was used to dismember the body six years ago can be said to be a desperate effort to find evidence now.

That is to say, Jiang Yuan's extreme self-confidence, coupled with the idea of ​​​​just giving it a try, led to this line of work.

If it were Wang Zhong himself, he would definitely not have this idea. When Huang Qiangmin wanted to make a request, he had to put up a few words of protest first.

"Turn on the lights." Jiang Yuan didn't let Wang Zhong do anything. He dressed neatly, especially a 3M mask, and then he lay on the ground and searched inch by inch.

After filming for a while, Mu Zhiyang felt tired even while standing, so he set up the camera and sat on the sofa with his eyes closed to relax.

"Woke up!"

Jiang Yuan kicked his feet and called out Mu Zhiyang.

Mu Zhiyang stood up, touched his lower back, and looked at Jiang Yuan. He was hazy for a long time before asking, "Did you find it?"

"No." Jiang Yuan curled his lips: "It's been too long."

He had turned on the temporary +1 skill, but he couldn't find it. In the past six years, Zhang Yi probably had to clean it up more than once.

To be honest, Jiang Yuan admired Zhang Yi for continuing to live in this house.

Ordinary people really may not be able to continue living in such a "haunted house" built by themselves.

Mu Zhiyang wiped his lips, feeling like he had slept for too long, and asked, "What should I do?"

"Move the furniture and let me check the living room."

Jiang Yuan said and started to investigate by himself.

Mu Zhiyang hurriedly carried the furniture with Wang Zhong and changed positions. They were very busy.

Two hours later...

"Get off work. Let Bureau Huang know. Let's see what he thinks."

Jiang Yuan shook his head. It is difficult for a clever woman to make a meal without rice. If there is no evidence, there is no evidence.

Mu Zhiyang said: "This is quite troublesome. There is no evidence. Should we arrest Zhang Yi and her concubine?"

Without evidence, arrests must rely on interrogation, which is actually the most unreliable method.

Especially for murder cases, there is no way to convict a person with only a confession from an interrogation. Even a little bit of physical evidence is not enough. A complete chain of evidence is needed.

Faced with this situation, Jiang Yuan ran out of ideas for a while and returned to the Zouma Road Police Station. The same thing happened.

"What's going on? Zhang Yi is still making trouble and wants to see her son." Tan Jing also got the latest news and came over to ask about the situation.

Jiang Yuan spread his hands.

Liu Wenkai asked: "Are we going to arrest him and put him on trial?"

No one answered for a while.

"Is her son lying?" As a veteran police officer, Tan Jing has a very deep understanding of people lying.

Meng Chengbiao recalled the interrogation process and shook his head slightly: "It doesn't look like that."

"Who is the victim? Has the victim been identified?" Huang Qiangmin guided the topic to the core issue.

Now if it is confirmed that there is a body, there will be evidence, and the investigation will be completed in one go.

But if there is no body, or the body cannot be found, murder cannot be established, and there will be trouble in the future.

"Or, could the son who reported the case have mental problems?" someone asked again.

Huang Qiangmin shook his head again and said: "I can test it later, but it doesn't look like it."

"Then...if that doesn't work, arrest Zhang Yi and her lover Li Gan together, and then interrogate each other. Prisoner's dilemma?" Liu Wenkai tried another plan after his plan failed.

"The risk is also very high." Jiang Yuandao.

It’s not easy for the prisoner’s dilemma to work if the police have nothing.

"Then let's interrogate An Zhiqiang again?" Huang Qiangmin could only take a step back, then looked at Jiang Yuan and said, "What's your plan?"

"Call Liu Chu to come over and take a look?" Jiang Yuan answered decisively.
