But I was more patient, so I continued to deal with her.

I quietly pulled Wang Cailing into a corner and whispered, "Just say what you know, right?" I won't tell anyone because I'm a police officer. ”

But what responded to me was still Wang Cailing's stupid smile.

"Police! Hey, police? She said, raising her hand and slapping my arm.

Is she pretending to be crazy or is she really crazy? I looked at her suspiciously, but I didn't dare to make a conclusion. At first, I suspected that this Wang Cailing knew something and didn't dare to say it, so she pretended to be crazy and stupid, but now it seems that she should be really crazy!

Wang Jiumei's only relative is crazy, and there is so little information about her, it is really difficult to find the murderer in this case.

Including Wang Jiumei's real cause of death, what is it? At present, even the forensic doctor can't say for sure!

Just as I was sighing, Wang Cailing actually opened her mouth and exclaimed, "Ghost! There are ghosts! It was the ghost who killed the ninth sister! Yes! ”

Ghost? Is there such a thing in the world?

Looking at the fear in her eyes, I was stunned! Naturally, I don't believe that there are ghosts in the world, because what Wang Cailing said is obviously crazy, and there is no scientific basis for that.

I shook my head, and just as I wanted to leave, I heard Wang Cailing behind me shouting hysterically, "Ah! Don't kill me! Then there was the sound of a heavy object falling to the ground.

When I turned around, I saw that Wang Cailing was dead and committed suicide by jumping off the building!

As for what she said before she died, although it was crazy, I vaguely felt that it was not that simple.

At this moment, I vaguely thought of something, so I turned my head to look at Chen Fang and asked, "When did Wang Cailing go crazy?" ”

"Hospitalized on the 12th, her attending doctor said that Wang Cailing had a three-year history of mental illness, paranoia and schizophrenia."

Schizophrenia? I paused, as if I had captured something. Could it be that Wang Cailing schizophrenia killed Wang Jiumei?

If so, then how did she do it?

Of course, there is another theory, that is, the ghost in Wang Cailing's mouth really exists. She saw with her own eyes that the "ghost" killed Wang Jiumei, and she went crazy under the strong stimulation. Of course, it's definitely not a ghost, but someone is doing it.

Either way, in the absence of conclusive evidence, everything is hypothetical.

The case seemed to have reached an impasse all of a sudden.

After coming back, in the face of various questions from colleagues, I had to go to the place where Wang Jiumei lived with Chen Fang.

According to the neighbors, Wang Jiumei is a street girl and a mistress who has been fostered.

When I came to Wang Jiumei's room, I refreshed my cognition of this "girl standing on the street".

The room is extremely tidy, and there are rows of famous books on the shelves, which do not look like a street girl at all, just like a young man.

This is the room of the deceased Wang Jiumei, which is completely different from what the neighbor said.

Obviously, the words of neighbors and landlords cannot be believed, and sometimes jealousy between women can destroy a city.

"Team Chen, where are Wang Jiumei's relics? Well, and her correspondence records. I asked.

"We have checked the communication records, and Wang Jiumei had no call records in the first half of the month, and there is no doubt about her QQ WeChat and other social software."

"How many social software does Wang Jiumei have, and did she extract clues that don't belong to her at the scene?"

Half a month before the incident, there was no call record, could it be that the murderer had already laid out the bureau half a month ago?

"Lu Zhe, this is Wang Jiumei's relic." Chen Fang pointed to the box next to the bookshelf, it stands to reason that the crime scene cannot be destroyed at will.

Judging from Chen Fang's expression, someone must have destroyed the scene of the crime.

"That's what the advisor did before."

I put on my gloves and took pictures and archives before I started, not missing every detail. When I photographed the last close-up of the bookshelf, I found a clue in a book called "The Pursuit of the Wind and the Moon".

This is Keigo Higashino's book, piled up in the inconspicuous corner of the bookshelf, and a lot of dust has fallen. But when I saw this book, something was different.

When I pulled it out, I saw a burnt piece of paper sandwiched in the book. There is even a word "kill" written on it!

This piece of paper caught the attention of Chen Fang and me. We immediately notified our colleagues from the Forensic Evidence Division to come and recover the evidence.

I, on the other hand, remained at the scene of the crime, continuing to search for useful physical evidence. But, sadly, I didn't find any useful physical evidence.

Wang Jiumei's computer and mobile phone have been formatted and emptied, and we can only find her social software and interpersonal relationships through her ID card information and mobile phone registration information.

Fortunately, news soon came from the technical department, saying that the data in Wang Jiumei's computer and mobile phone had been recovered. The data shows that there is a hidden encrypted folder in her computer.

This folder immediately caught our attention.

It's a pity that the section chief of the appraisal department is called Xu Liang, and Chen Fang is a sworn enemy. Maybe it was because he knew that Chen Fang and I were college classmates, and Xu Liang didn't have a good face for me.

I glanced at Xu Liang and asked, "Can this encrypted folder be opened?" ”

Xu Liang shook his head, his expression was full of disdain: "We have tried our best, this folder was made by real hackers, and there is no hope if it is obtained from the Municipal General Bureau, and we have sent it over at present, but according to the recovery data of the deceased's mobile phone, there is a person named Chen Cheng who had a close relationship with the deceased." ”

Xu Liang said that this Chen Cheng became the number one suspect when he landed. He is likely to be the murderer of Wang Jiumei, because a month ago, Chen Cheng quarreled with Wang Jiumei on social software because of emotional problems.

Of course, this possibility cannot be ruled out, and I immediately pointed out that I wanted to meet this Chen Cheng.

However, the population of this city is complex, and there are thousands of people moving every day, and the vast majority of people from other places alone, many of whom have not gone through formal procedures.

It is conceivable that in this vast sea of people, the possibility of finding a person is slim. Of course, there are also some people with the same name.

Despite this, we still urgently searched for clues about Chen Cheng, and Xu Liang's IP location also showed that Chen Cheng was in the city.

He urgently investigated Chen Cheng's namesake and found Chen Cheng after several twists and turns.

This is a young man in his twenties who lives in a slum. Chen Cheng is not tall, half a head shorter than me, dressed plainly, and is a very restrained young man.

When we met his parents and showed their intentions, both elderly people showed signs of trepidation.

After glancing at Chen Fang, I spoke, "Don't be nervous, we're just here to find out more about the situation." ”
