You Jia asked Li Chen to take people to Yang Wen's place to conduct a search, and when they arrested Yang Wen before, they didn't have time to check here in order to prevent Yang Wen from escaping.

Although this case was specially handled by their first-echelon people, other colleagues also contributed a lot to it, such as Yang Wen's information, which was specially transmitted to them by colleagues in Hexi City.

It is the cooperation of colleagues from all over the world that enables the people in the first echelon to obtain first-hand information, and You Jia is also very happy for this, after all, it is the result of their joint efforts.

The reason why Yang Wen was confirmed so quickly this time was also because of the information provided by colleagues in Hexi City, and after checking the aviation data, I knew that Yang Wen had come to Chengnan City a week ago, that is, Yang Wen had followed Jiang Ning here that day.

You Jia only remembered what he had ignored when he read this information, if he could remember it before, maybe Shi Yu and Jiang Ning would not have an accident.

Li Chen found a videotape in the place where Yang Wen lived, and also found a knife, he stood in the living room with a frown and thought, this knife should not be a murder weapon.

And there was nothing like a murder weapon at the scene, so what is the meaning of this knife, and what else is it, why are there always some ingots and candles in Yang Wen's room.

didn't think too much, Li Chen temporarily asked his colleagues to help him take these things back, Chen Yang also found a notebook in the room, the clothes in the wardrobe were basically white or gray, and there was no black clothes.

The forensic examiner checked the things that Li Chen brought back, and it turned out that there were no fingerprints on this thing, not even the knife that Li Chen brought back.

The tape Chen Yang took from Li Chen and handed it to Zhang Haichuan, and the things in the tape were actually the current situation and time of Shi Yu's death.

But this thing can't be killed by Yang Wen, if he says that this thing was picked up by him on the road, then You Jia can't do anything about him.

Although You Canon is sure that there is no problem with his inference, the most lacking thing at the moment is the evidence they are looking for, and if Yang Wen can cooperate with them to record a confession, then this case will be easy.

But Yang Wen is not like other criminals, nor is he the kind of stunned young man who can be bluffed, so You Jia decided to let Chu He and Ji Ziyue go to the interrogation room to interrogate Yang Wen with psychological interrogation techniques.

Chu He and Ji Ziyue took turns asking questions to Yang Wen, but Yang Wen just didn't accept the invitation and didn't continue to chat with them, as if he was deliberately delaying time.

"I said two Jing officials, the serial murder you are looking for is not me at all, I am a good person who abides by the law. So when will you let me out? ”

Seeing that the interrogation had reached an impasse, Ji Ziyue didn't look anxious at all, and took the initiative to ask: "Then you can tell me who the murderer is, where did the things that appeared in your house come from, and oh, and how did the videotape found in your room come about, tell me." ”

"How do I know, isn't it your business to handle the case? As for the videotape you said, I picked it up on the side of the road, what? What's the good stuff on this? Yang Wen replied with a mocking expression.

Ji Ziyue smiled at this moment and said, "Then why did you come here from Hexi City, we checked your recent whereabouts, and we found that you have no relatives or friends here in Chengnan City." Look at my mouth, I should say that you don't have friends, I'm really embarrassed, I said the wrong thing for a while. ”

Chu He watched Ji Ziyue and Yang Wen confronting each other with words, especially when Yang Wen heard Ji Ziyue say that he had no friends, Yang Wen's expression suddenly became a little different. Number One

He knew what Ji Ziyue meant, in psychology, only by breaking through the psychological defense of another person, he needed to say something that could stimulate him or something he cared about very much.

It seems that Yang Wen can gradually break through Yang Wen's psychological defense line under the stimulation of Ji Ziyue's words.

However, this time, Yang Wen didn't know what to ask, and no more information was revealed from his mouth, Ji Ziyue was still on the side and kept stimulating Yang Wen with words, Yang Wen obviously saw Ji Ziyue's little tricks, and a smile appeared on the corner of Yang Wen's mouth and said: "Jing Guan, I know that this is your interrogation technique, but it doesn't seem to work for me, I still say that, the things you said are not done by me, and I don't know them, what Shi Yu, what Zhang Ya, I don't know any of these people." ”

Ji Ziyue and Chu He looked at each other for a while, thinking that it was done, Ji Zi said with a smile: "I don't seem to have mentioned Zhang Ya from beginning to end, how do you know that this Zhang Ya is one of the victims?" ”

Only then did Yang Wen realize that he had accidentally leaked his mouth, and looked at Chu He and them with a dark face, and then Yang Wen never spoke to them in the back, and refused to communicate with them in a silent manner.

No matter what Chu He or Ji Ziyue asked, he kept sitting in his chair and didn't say a word.

However, Chu He and Ji Ziyue are both leaders in psychology, no matter how strong the criminal's psychological defense line is, they can use some repeated torture techniques to finally pry open this strong defense line.

However, a person like Yang Wen who took the initiative to fight with Jing Fang, and even a criminal suspect who had the upper hand psychologically, was absolutely unprecedented.

In the end, there was no progress in the interrogation, and You Jia and the others had to detain Yang Wen in a detention cell pending further investigation. Indeed, as You Jia thought, Yang Wen must have picked up the tape on the road, and as for where he picked it up, he directly said that he had forgotten it.

Here, Zhang Haichuan used the knowledge he learned to constantly look for the deep web on the Internet, and the emperor lived up to his wishes, and he finally found a clue to enter. He found that the contents of the tape had spread on the deep web, and many people had downloaded it to his mobile phone, and some people commented below.

He also saw that someone was tipping the video, and Zhang Haichuan put the information of the account as the IP on the laptop found in Yang Wen's house.

Now the most that can prove that this video was released by Yang Wen is not enough to prove that the person was killed, Zhang Haichuan also hacked into Yang Wen's computer and found that this person was very clean, and he would smash everything he thought was important.

"Boss, I think Yang Wen must have set things up in the computer, you give me the computer, I'll see if I can find things out tonight, I'll stay up late with you in the team tonight." Zhang Haichuan's voice was uploaded to You Jia's ears from the position.

You Jia looked over, only to see what Zhang Haichuan's hand was constantly operating, he knew that Zhang Haichuan would just say nothing to him and didn't need his answer.

Chu He watched this scene with amusement on the side, all of them clearly knew Zhang Haichuan's temperament, and he would not give up until he reached his goal.

However, they do need to stay up late in the office tonight, after all, there is not much time left, and Yang Wen just knows that the detention time is poor, so he will look so fearless.

Whether the suspect is a suspect or something, the criminal has only 48 hours to detain him. In other words, if they do not find any evidence to prove that the person is the murderer who participated in the murder within these 48 hours, they can only release him.

And Mu Jingyue's situation has other people to protect him, even if Yang Wen has been arrested, but for the sake of the future, Mu Jingyue's protection cannot be relaxed.

But no one expected that although Yang Wen was in the criminal investigation team, Mu Jingyue actually had an accident, just because Mu Jingyue went out to buy something, and then was dragged to the suburbs, killed and disfigured, and her whole body was splashed with sulfuric acid, You Jia only felt a headache, all the traces of Mu Jingyue's body that could prove her identity disappeared, the murderer was so cruel, it was beyond You Jia's imagination, according to the previous murderer's methods, it was different from now, could it mean that the murderer was hiding something?
