After leaving Chu Ming's house, Li Meng and I went directly back to the office of the Serious Crime Team of the Ningzhou Public Security Bureau.

Everyone has just come back, there is no way, there are too many people who need to be investigated and visited in this case.

After everyone's investigation and visits, ten of the 28 people who participated in the class reunion have been completely cleared of suspicion, and the rest will continue to investigate and visit tomorrow.

At present, three people have died in the "Seven Dragons and One Phoenix" campus bullying gang, and there are still five people left, namely: Yao Xun'an, Chen Qing, Li Yuanliu, Cao Xiaofeng, and Jiang Qingwen.

But after comparing the list of participants in the class reunion, I found that among the five people, Chen Qing and Cao Xiaofeng did not come to attend.

Tomorrow, I am going to go to Yao Xun'an, Li Yuanliu, and Jiang Qingwen to find out the situation.

Now what makes me hesitate the most is this person named Chu Ming, I suddenly asked Li Meng: "Do you think Chu Ming is suspected of committing a crime?" ”

Li Meng paused, thought carefully for a while, and said to me: "From the perspective of psychology and micro-expressions, Chu Ming is definitely not lying. ”

"Can you be sure?" I asked.

If Chu Ming is not lying, then three things have been proven:

First, Chu Ming didn't hold a grudge against this "Seven Dragons and One Phoenix" campus bullying team at all.

Second, Chu Ming likes Hu Yuanling very much, which also shows that he will never kill Hu Yuanling.

Third, he has a weak personality, is timid and inferior, and absolutely kills three people in a row.

At the same time, Chu Ming's suspicion of committing the crime was completely cleared.

Li Meng nodded very firmly, she is an expert in criminal psychology, she trusts her own judgment, and we also believe in her strength.

Because I also think so, Chu Ming's performance is absolutely impossible to pretend, the change of that kind of micro-expression is very natural, if he is really a murderer, it can only be said that he is also an absolutely professional psychologist.

In the office of the serious crime team, everyone came back, each telling about their visit and investigation today, and summarizing the case. Of the 28 people on the list, one personal name was erased because there was no suspicion of committing a crime.

"Are Hu Yuanling's autopsy results out? How did she die? I asked suddenly.

Everyone looked at each other and didn't answer.

"Section Chief Ren hasn't written from me, I don't know what the situation is." Lin Zifan said lightly.

"This Ren Qiushi, why is it so slow? That's not his character. I muttered, changed my words, and asked Jiang Tingbai: "Old dog, how is the trace examination department?" Did you find anything at the scene of the crime? ”

Jiang Tingbai let out a long sigh and said, "The technical team has conducted a careful investigation of Hu Yuanling's home, because the scene has a large flow of people, and the damage is relatively serious. We have extracted a large number of footprints and fingerprints, which are being compared with the doctors who came to the emergency department.

The fingerprints and traces were all on the way from the door to the restaurant where Hu Yuanling died, and no fingerprints and footprints other than Hu Yuanling were collected in other parts of the room, nor were any hair, dander or other biological tissues other than Hu Yuanling found.

In addition, the door lock was blown open when the door was broken, and there was no way to check whether the door lock had been damaged. ”

After listening to Jiang Tingbai's narration, my heart suddenly had mixed feelings.

The time of Hu Yuanling's death was very close to the time we broke in, and if we had arrived earlier, we might have been able to save a young life.

Destruction of the scene is inevitable because lives are at stake and we have to save them.

Everyone is still seriously summarizing the case, and I decided to go to the forensic department to see what kind of reputation this Ren Qiushi is doing.

Walking into the forensic department, Zeng Lan was walking out and almost crashed into my arms.

"Team Qin." Zeng Lan hurriedly took a step back and greeted me.

"Off work?" I asked casually.

Zeng Lan nodded and said lightly: "Well, I'm off work." ”

"What about Ren Qiushi?" I asked her again.

"Section Chief Ren is in a daze in the office." Zeng Lan said in a daze.

"Daze?"

My facial features were a little distorted and I asked, what is the situation with this Ren Qiushi?

"Okay, I'll go find him." I nodded, bypassed Zeng Lan's side, and walked into the forensic office.

"Goodbye Team Qin." After Zeng Lan said goodbye to me, she went home from work.

It's really strange, obviously Zeng Lan is also a forensic doctor, why doesn't there be any corpse smell on his body. It is absolutely forbidden to use cosmetics with any smell on the body of the forensic doctor, which will seriously affect the work judgment of the forensic doctor during the autopsy process.

I settled down and muttered, "It must be a division of people, Ren Qiushi is already stinky, well, it must be like this." ”

Walking into the forensic office, I saw Ren Qiushi sitting at his desk, lazily leaning on the back of his chair, his hands crossed behind his head, staring at the wall in front of him in a daze.

It seems that he was really in a daze, so much so that I didn't even notice when I entered the door.

In order not to scare him, I walked up to him and gently tapped the desk with my fingertips.

"Oh, Lao Qin, when did you come?!" Ren Qiushi came back to his senses and hurriedly asked me.

I smiled and replied, "I'm just here, what do you want?" ”

Ren Qiushi pushed the chair next to me and beckoned me to sit down.

He subconsciously pushed the chair far away, because he knew that I hated the smell of corpses on his body, and every time I would sit far away. But he didn't care that I disliked him, and even got used to it.

And he often uses the smell of corpses on his body as a weapon against me, and gives me a warm hug at every turn.

"I'm thinking about Hu Yuanling's autopsy." Ren Qiushi muttered.

After listening to him say this, I felt very puzzled, what does it mean to "think" about Hu Yuanling's autopsy?

"So, is the autopsy done? Has the cause of death been found? "I really couldn't stand his behavior of selling Guanzi, so I asked him directly.

Ren Qiushi looked at me and said with some hesitation: "The autopsy is done, and the cause of death has also been found, but the cause of death is very strange." ”

"Strange cause of death?" I suddenly had a black question mark face, what is the strange cause of death? For a medical examiner, it would not be surprising what the cause of death was.

In other words, what could be the cause of Ren Qiushi's death that could make Ren Qiushi feel strange?

Ren Qiushi did not choose to sell Guan Zi this time, and said directly to me: "Hu Yuanling died of low blood pressure. ”

"Blood pressure lowered?!" I looked at him with some shock, this cause of death, it was really strange.

Ren Qiushi nodded and affirmed: "Hu Yuanling died of cardiac arrest caused by low blood pressure, which led to circulatory failure, and the cause of death was at noon today, which is likely to be two hours before you broke the door and entered. ”
