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

The interrogation continues.

While Wang Zhaokai was interrogating Zhang Chao, Lu Chuan and others next door were also watching the interrogation process.

"Director Lu, how credible do you think what Zhang Chao just said is?"

Sun Biao was also watching.

Chen Ming and several other key investigators were watching the interrogation process of Wang Zhaokai.

Lu Chuan shook his head.

Just now when the technical team brought over the original analysis report for the first phase, Lu Chuan and his team had already read it and confirmed that Zhang Chao was the suspect. Then several people watched the entire process of Wang Zhaokai interrogating Zhang Chao in the monitoring room next door.

"I think the process Zhang Chao just described is not true, or only a small part of it is true, and the rest may be false."

To judge whether what a criminal suspect says is true or false, we cannot just judge based on some details during the interrogation process, but also need to analyze the person's past experience, his personality and behavioral habits comprehensively.

Zhang Chao can be said to be a repeat offender who has been walking on the edge of the law. Three years ago, he committed robbery and let his brother go to the police force while he himself remained at large.

During this time in Haizhou City, I didn't do any proper work.

During the DNA technical identification process, Lu Chuan arranged for people to investigate Zhang Chao's work history in Haizhou City.

It was discovered that Zhang Chao basically hung out in various entertainment venues, sometimes working as a waiter, sometimes as a security guard, and sometimes managing some small KTVs.

Basically, he has never done any proper job, so sometimes he earns more money and sometimes less. No matter whether he earns more or less, this person basically spends money lavishly.

Zhang Chao is the kind of person who lives for the moment, which has long been related to the fact that he makes money in an illegal way. Money comes too easily to him, and although it is not much each time, he does not need to put in too much effort to get the money.

"Zhang Chao's last job was at Dynasty KTV. He was fired because he made advances towards some of the KTV's singing girls. One of them's boyfriend beat him up, and they had a conflict, so he was fired."

Lu Chuan looked at Zhang Chao in the video very carefully.

During the interrogation just now, Lu Chuan had been observing Zhang Chao very carefully.

Although during the entire interrogation process, Zhang Chao did not hesitate or stutter when explaining how he murdered.

It seemed that every word he said came naturally, and his tone did not change much, and was very peaceful.

However, Lu Chuan discovered that sometimes when Zhang Chao was speaking, especially when he was describing the specific process of a murder, the corner of his left eye would tremble slightly.

The amplitude of the eye tremor is actually very small, and it is even possible that Zhang Chao himself cannot detect it. It should be a natural neurological tremor.

However, this kind of movement does not always exist. When Zhang Chao talks about his own information or when he talks about his contact with internet celebrities, his eyes never twitch.

Therefore, Lu Chuan had reason to suspect that the other party was lying or had this physiological reaction when he was nervous.

"When we listen to him talk about the physical process later, please pay attention to the corner of his left eye. Sometimes his left eye will tremble slightly due to nervousness."

Lu Chuan pointed at the surveillance camera and said, "The movement is very small, and it is very likely that Zhang Chao himself cannot detect it. But when the other party is nervous or lying, I think this physiological reaction will follow." Lu Chuan repeated his analysis and explanation, which attracted the attention of others.

What Lu Chuan said made everyone take it seriously.

To be honest, it doesn't matter what Zhang Chao says now, because with the DA's report on identifying the aircraft, there is no doubt that the other party is the murderer.

Moreover, from the perspective of the later trial, the details of the entire process of Zhang Chao's murder were no longer that important.

However, this so-called unimportance can only be judged when it is impossible to determine whether Zhang Chao is lying.

If what Lu Chuan said was true, and the other party's eyes would twitch whenever he lied, then the interrogation might need to continue and go deeper until the final truth is found.

In the interrogation room, Wang Zhaokai continued the interrogation.

"Tell me about Wang Lili's body. How did you deal with it?"

When Zheng Chang heard Wang Zhaokai asking him how he would deal with Wang Lili's body, his expression was obviously stunned.

Then, he took a deep breath and said, "After I killed her, I was terrified..."

When Zhang Chaochao said this, Lu Chuan and others in the surveillance video saw that the corner of his left eye did twitch a few times.

"I originally wanted to call the police, but I was afraid they would catch me and sentence me to death."

The corner of his eye continued to twitch.

"So I thought about hiding this matter. Then I saw a black suitcase on the cabinet in Wang Hong's house. I thought about putting Wang Lili's body in it and then find a place to take it out and bury it."

There was no reaction from the corner of the eye.

"But after I got the suitcase over, when I tried to put Wang Lili into the suitcase, I found that she couldn't fit in at all."

There was no reaction from the corner of the eye.

"I thought if there was no other way, I should just split her in half. If I broke her into pieces, I might be able to fit her in."

There was no reaction from the corner of the eye.

Zhang Chao narrated the whole process of dismembering the corpse. During this process, there was no reaction in the corners of Zhang Chao's eyes.

He found the broken kitchen knife in the kitchen, and then used it to dismember Wang Lili's body. During the whole process, he used a lot of clean water to wash the bathroom floor, and then used a mop to clean the entire floor. He also used a mop to clean the floor in the room.

Moreover, Zhang Chao did not simply clean it. He used a lot of detergent. During the process, he was even afraid that the police would find out, so he went out and bought two bottles of detergent.

"I knew from watching movies that blood stains are very difficult to clean. You can rinse them with clean water and then shine a fluorescent stick on them to reveal them."

"So I was very careful and used the mop to clean it. When I found the traces in the living room, there was no blood on the mop. Then when I was in the bathroom, I washed away the blood with water, and then I used detergent to wipe it many times before I finished. It was almost three or four in the morning when I finished all this. It took several hours and I was almost exhausted." (End of this chapter)
