What Liu Jia said caught my attention, she said that Dr. Liu never brought outsiders back to his home, but a few years ago, Dr. Liu brought back to his home twice in a row a young man that Liu Jia had never met. I immediately made further inquiries, but Liu Jia didn't know more detailed information.

It was also about four years ago, when Dr. Liu came back when Liu Jia was tidying up his father's room. It was also the first time Liu Jia saw the young man, and Liu Jia was quite impressed, because the young man was very polite and looked very gentle.

After the young man and Dr. Liu returned home, they went straight into the room. Dr. Liu also called Liu Jia out, after which Dr. Liu closed the door. Liu Jia remembers that the young man and Dr. Liu had been in the room all afternoon, and when the door opened, it was already dark.

Liu Jia had already cooked the meal, and she thought that the young man would definitely stay at home to eat, but unexpectedly, the young man left in a hurry. Before leaving, the young man also thanked Liu Jia very politely for his hospitality. That day, Liu Jia ate alone, because she went to ask Dr. Liu to eat, and Dr. Liu only said that he had no appetite.

Dr. Liu sat on the edge of the bed and sent Liu Jia out. Liu Jia was a little worried at first, because Dr. Liu didn't seem to be in good spirits. But the next day, Dr. Liu returned to normal, so Liu Jia didn't think much about it. Unexpectedly, a few days later, Dr. Liu took the young man home again.

Like the first time, the young man stayed in the room with Dr. Liu again, and this time, they stayed in the room for a longer period of time. By the time they came out, it was already eleven o'clock in the evening. Liu Jia hadn't slept yet, and when the young man went out, he bowed to Dr. Liu, who was staying in the room.

Dr. Liu personally sent the young man out, and later, when Liu Jia asked who the young man was, Dr. Liu only said casually and perfunctory. And on that day, Dr. Liu's spirit was also not very good, this time, Dr. Liu sighed for several days, and even did not eat much.

My heart was beating so fast that I had some kind of speculation, but I didn't want to believe it. So, I asked Liu Jia if there was any way to guess what the identity of that man was. Liu Jia frowned and thought for a long time, and finally, she seemed to remember something. She said to me, "When my father was sending that man out, I seemed to hear the man calling him teacher. ”

My heart trembled suddenly, and it was very likely that the person named Dr. Liu was a student who had studied at the police academy. As far as I know, among the previous students, Dr. Liu is the only one who is particularly familiar with Du Lei, in addition to me.

Du Lei is a very special person, his academic performance is not good, but Dr. Liu can call Du Lei's name in class.

With so many students, it was almost impossible for Dr. Liu to remember the names one by one, and at that time, Du Lei did not look like a student who would catch Dr. Liu's attention in all aspects.

Since then, Du Lei has often queued up outside Dr. Liu's research room, and like everyone else, Du Lei is interested in psychology and everyone wants to have a chance to talk to Dr. Liu. It was also from that time that I learned that Dr. Liu seemed to like Du Lei very much, because every time, Dr. Liu only talked to Du Lei for a long time, and as for the others, because of time, Dr. Liu either disappeared or ended the conversation quickly.

At that time, I was very happy for Du Lei, and I thought that Du Lei, who had the lowest grades, would improve his grades after talking to Dr. Liu many times, at least he would get good results in criminal psychology. But I didn't expect that Du Lei's results were still mediocre as always, and even very poor.

Then, the student who was taken home by Dr. Liu was probably Du Lei, because I really couldn't think of anyone other than Du Lei who would make Dr. Liu willing to take him home, and even talked for several days.

"Did Dr. Liu call that person's name?" I asked.

Liu Jia thought about it and shook her head.

I refused to give up, and asked again: "Is there really not, is that person called Du Lei?" ”

But Liu Jia really couldn't remember, I sighed, and was about to give up, I immediately remembered that Liu Jia had seen that man, as long as I took Du Lei's photo to Liu Jia to identify, everything would be clear. I asked Jiang Jun and Liu Jia to wait for me in the research room, and I immediately ran towards the unit.

In the unit, there is a photo of Du Lei. Although many years have passed, it is not difficult to compare the photos with some impressions.

On the way to the unit, I bumped into a man I knew. After seeing each other's faces, I apologized and was about to leave, but I didn't take a few steps before I stopped again. I turned around and stopped the man, and I smiled at him, "There's something I want you to help with." ”

More than 20 minutes later, I found Du Lei's photo in the unit and returned to the research room. Jiang Jun and Liu Jia have been waiting here for a long time, I handed over Du Lei's photo to Liu Jia for the first time, and asked her to identify it, Liu Jia took the photo, carefully observed it for a while, and finally, she gave a conclusion: That young man is Du Lei!

The young man's identity was confirmed, but I didn't know if it was good news or bad news. Wang Xin has a relationship with the case, Du Lei is also related to the case, and both of these people have an extraordinary relationship with Dr. Liu, and all kinds of signs indicate that it seems that Dr. Liu is involved in the case, at least, he knows something.

Dr. Liu and Wang Xin deliberately hid their friendship from each other, and Dr. Liu, who never brought outsiders home, took Du Lei to his home again. I don't think Dr. Liu and Du Lei talked in the room twice for so long to discuss psychology.

At that time, Du Lei seemed to have graduated or was about to graduate, but it was not difficult for Du Lei to enter the police academy. Dr. Liu spent most often in the research room, and there was no need to take Du Lei to his home. Moreover, after the two conversations, Dr. Liu's behavior was very strange, sighing, so the content of Du Lei's conversation with Dr. Liu must be heavy.

Combined with the fact that Dr. Liu guided me to Dean Luo's orphanage to investigate before he died, it seems that Dr. Liu really has a problem.

Of course, I didn't tell Liu Jia my speculation, Jiang Jun also understood, and he chose to hide it for the time being. After that, Liu Jia stayed in Dr. Liu's laboratory to study, while Jiang Jun and I walked around the police academy. Jiang Jun frowned, and he said that he didn't know how to talk to Liu Jia.

I patted Jiang Jun on the shoulder: "Don't worry too much, everything hasn't been checked yet." Moreover, even if Dr. Liu has something to do with the case, I don't think he will be an enemy of the law, just like Captain Wang, although he is involved in the case, I also believe that his life is worthy of the law and justice. ”

After listening to my words, Jiang Jun was no longer so pessimistic.

We walked around the police academy for a while, and then I took Jiang Jun into an office. There was no one in the office, so I sat down. Jiang Jun asked us what we were doing here, and I told him with a smile that I wanted to find a way to catch the murderer who instigated Chen Yan's murder.

Jiang Jun was a little surprised when he heard this, he looked around, but it was just a very ordinary office.

"The murderer is from the police academy?" Jiang Jun asked in surprise.

I laughed and said, "You misunderstood. The people who can help me are working in this office. ”

Jiang Jun didn't ask any more questions, and we all sat quietly and waited. Time passed quickly, during which people kept walking around the office, and some people glanced around the office and saw that it was me, and they all nodded to me. Some of them were still students, and they asked me outside the door when I would start classes again.

Hearing this question, my heart felt a little bitter. I'm afraid, even if I get all the cases clear, I won't be able to start classes again in the place where my dream began.

It was at this time that our long-awaited office owner finally returned. Jiang Jun followed my gaze, and the person who came was a man wearing glasses with high myopia.
