I'm just a trainee police officer. I don't really want to solve the case.

When Sister Hua heard that someone had died again, she almost fainted from crying.

Who did this? Why did they only trap her? What should she do now?

The body was found in Room 501, just below Room 601.

The third victim is a small internet celebrity named Linda, who is 26 years old. She often does food broadcasts and sometimes also promotes products.

Wang Quanzhen should be her real name.

The person was strangled to death in bed, and the sheets and quilt were crumpled into a mess.

The victim's shirt was pulled down to his chest and his pants fell to his knees, suggesting that he had been raped after death. There was a smell of lubricant on the condom.

The time of death is similar to that of Ma Wu and Zheng Meilin. We will have to wait for the autopsy report to come out to find out the exact details.

Qi Lei was also very troubled. Two murders occurred in one day, killing three people.

There is still no clue in the cases of Ma Wu and Zheng Meilin, and now there is Linda's case.

Linda live-streamed until midnight that night, and the audience in the live-streaming room can testify to this, so her time of death must have been after midnight.

The door lock of the room was intact, which meant that the murderer did not break the door lock to get in. Either the murderer knew Linda, or it was more likely to be a takeaway or courier boy.

Linda is a single woman, and if it weren't for these two situations, she would not easily open the door to others so late.

Of course, if that person has the skills of unlocking or climbing walls like Su Xiaoxiao, he can also go in by himself.

Linda was different from the other two victims. She was slowly tortured to death by the murderer, and her hands and feet showed signs of fierce struggle.

The murderer seemed to be playing a cat-and-mouse game with her. He would let her go when she fainted, and then strangle her again when she struggled. He tortured her repeatedly before killing her.

This case also looks like a vendetta. The murderer must have hated Linda so much that he tortured her in this way.

Su Xiaoxiao walked to the balcony and looked up. The balcony of 601 was just above 501. She could easily flip from 501 to 601.

Forensic Doctor Zhang was busy conducting preliminary examinations on the body, and colleagues from the technical department were also conducting on-site inspections. They were all more professional than Su Xiaoxiao.

Su Xiaoxiao walked to the bathroom. There was still a little moisture on the floor and she smelled a familiar scent. It should be shower gel, similar to the one she used.

The bathroom was very clean, as if it had been cleaned after use, and there was no trace of hair at all.

The kitchen was also very clean, with pots and pans in their proper places and knives neatly stacked on the knife rack. It seemed that Linda might have mysophobia.

"What do you think?" Qi Lei walked over and looked around. He had a vague idea in his mind, but he couldn't grasp it for a moment.

He is now very convinced of Su Xiaoxiao's abilities. This girl has a strange way of thinking, which can always give him sudden enlightenment and inspiration.

"I do have an idea." Su Xiaoxiao said, her nose wrinkled up and down, very cute. Qi Lei almost had the urge to reach out and touch it, but then he realized what he was thinking. Was he possessed?

He touched his nose embarrassedly and asked Su Xiaoxiao to speak boldly.

"I suspect the same murderer committed these two crimes."

"But the modus operandi of these two cases is completely different. One was a slashing of the throat, and the other was strangled. There is no similarity."

“On the surface there are indeed no similarities.

You see, the kitchen and bathroom are extremely clean. We all think that Linda might be a germaphobe, but what if not?

In fact, the murderer was a mysophobe. He cleaned the bathroom and kitchen in order not to leave any traces of his presence.

For example, this knife."

Su Xiaoxiao said as she pulled out a knife from the knife rack. The knife looked very sharp. Qi Lei had seen it in an advertisement. It was called Old Man Li's knife, and it was said that it could cut meat as easily as cutting tofu.

The shape of the knife matched the wounds of the two men perfectly.

"This knife was probably used by the murderer to kill Ma Wu and Zheng Meilin. In fact, he killed Linda first in 501, and then the person upstairs angered him for some reason.

I guess they were shouting too loudly, which made him irritated, so he pulled out the knife and climbed from the balcony of 501 to the balcony of 601, because we only saw traces of climbing above the fifth floor.

We all thought he was very careful, but in fact he didn't go downstairs at all. After killing someone, he returned to 501.

He was a mysophobe and couldn't tolerate the smell of blood on his body, so he used the bathroom to wash. He used the shower gel because I didn't smell any shower gel on the deceased. Afterwards, he cleaned up any hair that might have been left.

The kitchen was also cleaned up, and he was very careful to remove any possible traces.

But even if he cleans it, there may be blood stains on the knife. If we take it back for testing, we may be able to find blood stains. "

Su Xiaoxiao put the knife in her hand into the evidence bag and test it with the luminol luminescence test when she returned.

Qi Lei agreed with Su Xiaoxiao's idea, and his mind suddenly opened up.

The murderer originally wanted to kill Linda alone, but he didn't expect the two upstairs to be so annoying, so he went to the kitchen to pull out a knife and climbed upstairs. Why did he use a knife instead of a rope? Of course, it was because the rope was cumbersome and it was not easy to kill two people at once.

The murderer had very good psychological quality. Even in such an angry state, he was able to deal with the scene calmly and erase all traces left behind.

Ma Wu and Zheng Meilin just happened to be victims of the murderer's anger.

It is terrible that he brutally killed two people just because of a momentary rage. We must find him as soon as possible.

Judging from the murderer's proficiency, this is probably not his first crime and he may continue to commit crimes in the future. It is too dangerous to let such a person roam around outside.

Medical examiner Zhang went back to examine the knife, spraying luminol on it, and it showed a clear bluish-white glow. There was indeed blood on the knife, and it was not animal blood.

It is now basically certain that the knife in 501 is the murder weapon that killed Ma Wu and Zheng Meilin, but there is still no clue as to who the murderer is.

Linda is just a girl in her twenties, who could hate her so much?

Because she was doing a live broadcast on the Internet, she spent most of her time in the room.

She has a room specially cleared out for live streaming, which is decorated very warmly. Her social circle is very narrow and she basically never goes out.

Who did such a person offend?

Soon, a top figure on the list appeared in the criminal investigation team's field of vision.

The top guy on the list has the online name of "Give You My Little Heart", which sounds disgusting.

He seemed to pay a lot of attention to Linda and would give her gifts every time he went live. They found out that this top guy on the list often asked Linda to meet up in private, but Linda didn't buy it and only gave him a good face when she gave him gifts.

The top guy on the list asked someone to find out Linda's address and even posted the address online.

He threatened to have sex with her during a live broadcast, and there are screenshots of the live broadcast room as evidence.

The key is that this man has an identity that is very consistent with the murderer. He is a martial artist and was once the provincial team's knife-fighting champion. He is fully capable of slitting someone's throat with one knife.
