The next day, Zheng Li really did a test on Xue Wen. It turned out that Xue Wen turned out to be a completely normal person.

"Since you are insane, why are your confessions different before and after?" Zheng Li asked curiously.

Sitting next to her, I kept staring at Xue Wen, a little guarded. I'm worried that Xue Wen will suddenly pounce and attack Zheng Li.

However, Xue Wen did not do that, but kept his eyes calm, as if he was thinking about something.

He sat quietly for a while before replying, "The reason is very simple, because I suddenly figured it out, so I turned myself in." ”

But is the truth really what he says? I'm skeptical.

So I stared at him suspiciously, wondering why he was lying.

But he was so calm that he didn't even say a word.

Zheng Li and I didn't ask anything in the end, so we could only walk out and talk outside.

"Do you have any thoughts on Xue Wen's matter now?" Zheng Li asked.

I shook my head secretly and said, "If he insists on turning himself in, and believes that he killed the person, then I can't do anything about it." But I always feel that he really didn't kill people. ”

In the end, I decided to go to Xue Wen's house and maybe find some clues. And I didn't even say anything about Zheng Li about this matter.

After work, I came to Xue Wen's house alone.

At Xue Wen's house, I smelled a foul smell. It was a smell of corpses, so I searched for it and went to the bathroom.

The bathroom in his house is dirty enough, and it looks like it hasn't been cleaned in a long time.

But it's not strange, it's just that the smell is very strong, and it's like the smell of corpses that I would smell when I taste it. Just as I was about to leave, I found that there were red marks under the crack in the door.

That must be bloodstained, right?

Out of curiosity, I slowly crouched down, pulled the door open a bit, and looked. As a result, there was a dead cat behind the door.

The cat must have died, and there were many wounds on the corpse, as if it had been bitten by something! Looking at this trace, it is very likely that it was bitten by a rat!

Ordinary people probably don't care too much, but as a criminal investigator, I immediately thought of why this cat died here?

I was immediately curious about the cause of its death.

So I found a bag, packed it and took it to a forensic center in the suburbs, where I asked the forensic doctor to do an examination of the cat's cause of death.

The forensic doctor conducted an examination on the spot, and the results found that the cat's blood contained a large amount of psychotropic drugs. Therefore, it is initially suspected that this cat had been given this drug before death. And it was confirmed that the cat had been dead for several days.

But Xue Wen is not a mental patient, why does he have such a psychotropic drug?

This really makes me curious!

In order to determine if the cat was his, and to make sure that he knew about it, I approached him and asked, "You have a cat at home, do you know it?" ”

He nodded secretly and said, "I know, but I'm dead, right?" I killed it, what's wrong? ”

"Why did you kill that cat?" I asked.

He raised the corners of his mouth, a terrifying smile, and said, "It's simple, because I have mania, so it's normal to kill it. By the way, it's not illegal to kill a cat, right? Even if it's a crime, it doesn't matter. ”

"Why doesn't it matter?"

"Because...... I've already been charged with murder anyway, so what's the point if I'm charged with killing a cat? With that, he laughed like crazy.

Looking at his smile, I felt panicked, and I felt some cold sweat running down my back.

On the road late at night, it was silent.

I was walking alone on this road, and I didn't want to go home yet, I just wanted to go to have a meal and go back to the police station to investigate.

As soon as I came to the restaurant that sold supper, I saw Ni Jiaxin sitting here, talking to Xiao Liu.

I walked over and asked, "You two aren't going back so late?" ”

When they saw that it was me, they all turned their heads and shouted, "Officer Lu." ”

I sat down, ordered a bowl of porridge casually, and then listened to Xiao Liu say: "Now the stocking murderer has not been caught." Another woman was killed, so we worked overtime in the hope that we could quickly set up control and find the murderer. ”

"Is it still hard to do? Didn't find any useful clues? I asked the two.

They all nodded.

Ni Jiaxin even said: "The murderer is very smart and cleverly avoided the place where there are surveillance cameras. And through the relationship between the deceased, we don't have many clues other than knowing that they all have the habit of wearing stockings. ”

At this time, the boss happened to come over with porridge.

He unexpectedly heard us discussing this case, so he leaned over and whispered to us, "Three police officers, I have actually heard some rumors about this case. ”

"Oh? Are you sure? I pulled out my chair and motioned for him to sit down and talk.

As soon as he sat down, he whispered to us, "I heard that this case was done by a madman nearby." ”

"Crazy?" I looked at him curiously.

He nodded and said affirmatively: "That madman had a wife in his early years, which was quite good. He wasn't crazy at that time. But I heard that later, his wife actually seduced people, and then she liked to wear those black stockings. It was for this reason that after he killed his wife, he went around killing women who liked to wear black stockings. ”

I thought to myself, if what he said was true, then the case could be solved.

So I turned my head and said to Xiao Liu, "You guys are going to investigate that madman tomorrow, right?" Let's see if this case is really his doing. ”

"Okay." Xiao Liu nodded in agreement.

At this time, I subconsciously looked at his right hand, "How is your hand now?" ”

"It's okay, Officer Lu." Xiao Liu secretly clenched his fists, "It doesn't affect the investigation." ”

I smiled reassuringly.

When the boss went to work again, Xiao Liu asked me, "Officer Lu, what about this case you are investigating now?" It's almost over, right? The only eyewitness, Xue Wen, had already turned himself in. ”

I secretly breathed a long sigh of relief and said, "I never think he is the murderer, so I will investigate this case well." ”

Ni Jiaxin had already finished eating, so she gently supported her cheek with her right hand, looked at me helplessly, and said, "Actually, why are you so stubborn?" He is a manic person who can hurt and even kill people at any time, so it is actually reasonable for him to kill people. I feel like he killed people. Even if it's not, let him be in society, it's also a timed **! ”

Xiao Liu actually nodded, agreed with Ni Jiaxin's idea, and said, "I think too." ”
