Du Yuting immediately analyzed the relationship between Li Zhixue and the previous female deceased Jing Yitong, but after a series of screening and comparison, she told me: "The two don't know each other at all, if you follow the serial killer you judged before, there is a great possibility of indiscriminate killing in this situation, and there is no possibility of violation, property embezzlement and hatred in this way of killing." ”

"As a rule of thumb, it does." I replied, looking at Du Yuting's screen before continuing: "Then you can investigate again, will Wei Pengyun have anything to do with Jing Yitong?" ”

Du Yuting took out a piece of chewing gum and chewed it carefully, while quickly tapping the keyboard, at this moment I noticed that there was a massager running under her feet, this guy is getting more and more casual now!

But leisure is leisure, but her work efficiency is still good, and she said to me after a while: "I found it, Da Dazi, the two don't know each other, but I found out that he actually knew Cen Zhixin...... Hey...... No way? This Cen Zhixin also worked in Huaihai Center Design Company before, but he changed his job 3 years ago and went to the electronics company. ”

"It seems that this guy is really getting more and more suspicious, have you investigated Cen Zhixin's academic qualifications?" I asked, ignoring the publicly, calling me my old nickname.

"Investigate now...... Well, this person is studying design, and it's a bit outrageous to go to do electronics, so I have to remind Team Leader He. ”

Du Yuting sent a message, and He Sheng replied in the group, telling us that they were tracking Cen Zhixin, but they haven't found it yet.

Everyone's attention is on this person at the moment, I think now if He Sheng and they go to track down, this person will not be left alone for the time being, I suddenly glanced at Su Yaxin, and then she immediately showed a "comprehension" expression and followed me, Du Yuting gave Yaxin two pieces of chewing gum before, as if she wanted to deliberately reward us.

When we came outside, we got into the car, and after starting the car, we found that Su Yaxin didn't know when there was an extra bag of chestnuts in her hand: "It's this again, aren't you tired of it?" ”

"Ha, whatever, men eat this tonic body."

"Are you sure?"

"Let's eat!" She stuffed me with a mouthful of chestnuts, and I barely ate a bite but immediately said seriously: "Do you know what I'm going to do?" ”

"It's definitely not chasing Cen Zhixin together, after all, everyone is dispatched and there is an Internet police investigation, that guy can't escape."

"Guessed right, Du Yuting just sent me a message and found one of Cen Zhixin's residences, let's go find the murder weapon now, but I asked Team Leader He to send another team to search near the crime scene, hoping to find other traces and physical evidence."

"I understand, because although we have some basis now, we don't have the necessary physical evidence, and even if Cen Zhixin is caught at that time, he can deny it."

I gave her an expression that was exactly like this, and when we came to a rental house, I asked the landlord here, and learned that we were policemen, this fat woman was very cooperative, and immediately took us upstairs to the 304 unit, after opening the door, we put on the survey equipment before entering the house, here we used a metal detector to feel everywhere, at this moment Xiao Dong sent me a message: "Forensic doctor Chen, the computer just got the result, the club-shaped murder weapon should be an iron water pipe!" The size is ф50 (wall thickness 2mm). ”

"Okay, thank you! You're really my timely rain! Xiao Dong! "I replied to a message, asking Su Yaxin to focus on finding such a hot iron pipe for me, we first came to the bathroom, then the kitchen, and the other is the utility room, but unfortunately it was not found, it seems that we judged that the murderer left the murder weapon at home, but at this moment I was about to leave the bathroom, but I found that the pipe next to the wash basin seemed to have a slight crack.

I carefully pulled it hard through the latex gloves, but I didn't expect this thing to be removed directly, but there was no water flow, I checked the switch above, and Su Yaxin next to me realized what was going on and said: "It seems that before this pipe was dismantled, Cen Zhixin turned off the switch, otherwise the water will definitely gush out after the iron pipe is removed!" ”

Although I understood, I couldn't help but turn on the switch, and as a result, we were all sprayed with water, and Su Yaxin glanced at me with a resentful look: "Dead senior, what are you doing?" ”

I smiled wryly and put the iron hose in the physical evidence bag, I didn't get sprayed by the water just now, I hope it doesn't wash away the useful traces and physical evidence.

When we returned to the Public Security Bureau, the investigation team also came with good news, it turned out that He Sheng and they had successfully found Cen Zhixin himself in a restaurant, and arrested him on the spot, this guy didn't know what was going on, maybe he didn't think that we would find out about him, when he was arrested, he was still there leisurely eating Western food.

Before the test results of the laboratory came out, I asked He Sheng not to interrogate, he agreed, and waited for me with Gao Mingqiang in the laboratory department, 3 hours later, the test results of the iron water pipe came out, and it was found that there was a lot of aluminum powder on it, and it was the DNA of the two deceased people in the ancient tomb!

Getting this conclusion, it can be said that it is already ironclad evidence, even if the motive for the murder is not found for the time being, Cen Zhixin is difficult to quibble, He Sheng immediately conducted a surprise interrogation of him, Gao Mingqiang recorded on the side, when he saw the copies of those reports, he also became restless without fear before: "How did you find these?" I'm not already pretending to be ......"

"Hehe, go on, there is such physical evidence that you don't want to say, and the court will sentence you, but if you keep silent, then you won't even have the last chance to tell us!"

He Sheng reminded him solemnly, but Cen Zhixin didn't seem to appreciate it very much, and he said indifferently: "I understand that if you don't say this, you may also find my DNA on the Nokia phone, right?" ”

"Yes, but why use that kind of phone? Can you give a reason? ”

Hearing He Sheng ask this question at that time, Cen Zhixin laughed wildly, his hands trembled, and his legs swayed unnaturally, but he was not afraid but excited! It's like our team leader He just played a century-level international joke with him!

"Can't I buy a few more mobile phones? Is there a legal rule that you can only buy one mobile phone? Or can you only use the latest mobile phone? Cen Zhixin said as a matter of course, when I was in the observation room, I found that his reaction was not as uneasy as before, or he now knew that he could not deny it, so he let it go.
