I deliberately dragged out the last few words, even if I had a guess in my heart, but I still deliberately didn't say it, sure enough, Dean Liu's face changed slightly, and a few drops of sweat appeared on his forehead: "Don't talk nonsense, I only have a teacher-student relationship with her, she has been here since she was 12 years old, her parents were working in the mine, but due to the collapse incident, she was thrown everywhere by several relatives, and then her aunt sent her to the welfare home, otherwise this child would not have come here." ”

When mentioning these, Dean Liu behaved very naturally, I guess this matter should be true, before I thought she was Yan Guyan's mother, or some dear relative, but to make sure that the time comes, I have to find Du Yuting to check, I secretly sent a message to her, Du Yuting quickly took action, and then Li Qiaodie continued to ask Dean Liu about Nie Zimo and Xiang Congling, she couldn't answer for a while, and then found a few nursery staff who said they had forgotten, but one of the nursery staff surnamed He told us, Now that the nursery worker Luo has left the welfare home, he used to bring Xiang Congling and them, and if you want to know more information, you can only go to him.

I informed He Sheng, he took someone to find He Furong first, that is, the nurseryman, we returned to the Public Security Bureau, after learning about Dean Liu and Yan Guyan, Du Yuting told us: "I went through the means of gateway assistance, entered the command to find some of their network chat records, although there is no mobile phone and computer, but still from the ID card information, found their information to open WeChat and QQ, I used the software to crack the password and log in, restore the chat records above, I found out that they haven't been in touch for a long time, but they have been in touch recently......"

Dean Liu: "If you don't have a good time outside, you can tell me at any time, and I will help you." ”

Yan Guyan: "Thank you for being kind to me, in the past, when I was alone, I was the only one who accompanied me, supported me, and protected me, and now it's time for me to repay you, you received the money." ”

Dean Liu: "I don't care about this, I saw someone die recently, it can't be yours, right?" ”

Yan Guyan: "You mean the two who fell in the zoo?" ”

Dean Liu: "Yes, I know that you have a good grasp of physics and good time control, and you are the only one who can control the time of the crime so well, and I knew that you did it when I watched the news at the time!" ”

Yan Guyan: "Heh, Dean Liu, isn't this all taught by you?" At that time, I realized why you took so much care of me, because you saw your shadow in me, and although I am not related to you by blood, I am closer than my own mother and daughter. ”

Dean Liu: "You must be careful, don't expose it, hide it, there is a place that should be more suitable for you, and it is difficult for the police to find there, I will give you an address." ”

Yan Guyan: "Thank you, teacher, I'll try it, I'm going to hide for a while, but I can solve the two bastards of Nie Zimo and Xiang Congling, as well as the wedding scene, they are all on the road together, and my task is completed." ”

Dean Liu: "It's been so many years, you still haven't let go of these, but according to your character, you have revenge, I still say that, you have to be cautious, and then you have to be calm if you don't take a step, pay attention to it when you contact me, I remember what kind of technology the police have now, even if you don't get someone else's communication equipment, as long as you go through the gateway and ID card, you can still find out everything, even if we delete the chat history, there will be a cache on the gateway." ”

Yan Guyan: "I have also heard of this kind of technology, it has only matured in recent years, and there is also the technology of networking with the traffic police department, it is said that it can be connected to the Internet by entering some instructions, and then they want to check the eye of the sky is very easy, and they can quickly grasp the information of many people, after all, there is still a large database of skull restoration technology and face recognition, and the defective thing in my country is only the DNA database, but I didn't leave any clues, they couldn't find me." ”

Most of the chats in the back are records of them talking about some things in the past, we didn't delve into it, looking at the chat content above, Du Yuting complained: "They really understand the laws of the police investigation, but those are just furs, and the real connotation is not something that ordinary people can understand, after all, they are laymen." ”

"Yes, judging from the content of the chat, it turns out that she did the case of the wedding car, Nie Zimo, Xiang Congling, Dong Congyan, Li Zhiliang, these people have all had hatred with Yan Guyan in the past, I can understand others, but how could Dr. Li?" Su Yaxin wondered.

I said: "Li Zhiliang should have been accidentally affected, in fact, the real purpose of Yan Guyan at that time should be Dong Congyan." ”

"If that makes sense, now that we have the evidence, we can all send Yan Guyan to the guillotine with this chat record, and it would be better if we could get physical evidence and her motive for killing, after all, there is not too much evidence." Su Yaxin concluded.

I nodded and agreed with her: "The evidence is to make the suspects admit guilt, but also to allow the court to convict them, and another role is to prove their guilt!" ”

……

On this day, just after lunch in the afternoon, He Sheng and Gao Mingqiang came back, judging from their happy faces, I knew that they must have asked some key information from Teacher He's body, He Sheng said: "It turned out that those children had forced Yan Guyan to do some reluctant behavior, at that time Nie Zimo was their boss, Xiang Congling and Dong Congyan did not dare to disobey his orders, about 8 years ago Nie Zimo fell in love with the beautiful and slender Yan Guyan, he let Xiang Congling and Dong Congyan stun her, Then get it to your own room......"

After learning about these situations, there was good news from the laboratory, it turned out that some blood stains were found on a screw, and after testing, it was found that it was Yan Guyan, and I don't know how she inadvertently left these blood stains at that time, probably because she accidentally scratched it, but these are not important, no matter how they were left, this screw is enough to become our physical evidence.

At the scene of the wedding car, we also found some new clues, the temperature of the car at that time was a little higher than normal, Du Yuting checked and monitored and found that one day, a woman approached the wedding car, and installed something inside the engine, and later dismantled the car to study, and found that it was a heater.

After getting all the evidence, He Sheng was extremely excited, and he invited me to face Yan Guyan with him again, but this time, Gao Mingqiang, Su Yaxin and Du Yuting were all in the interrogation room together, and the five of us interrogated Yan Guyan together.
