Xu Shu kicked the door too loudly, and when he came out, he happened to look at the neighbor at the opposite door.

"Officer, I'm just looking." The neighbor just wanted to close the door, but was stopped by Xu Shu.

"Come out, I have something to ask you."

The neighbor stood in front of Xu Shu, "You said, I will never hide it." ”

"Do you know when the other side went out?"

Xu Shu pointed to the room he had just come out of.

"Nope." The neighbor shook his head, "I slept relatively well today, and I didn't wake up until I heard a lot of police talking outside." ”

Xu Shu was keenly aware that something was wrong, which was not recorded in the transcript, "Did you hear the shouting before the police arrived?" ”

"Nothing." The neighbor didn't want to shake his head, "I've been sleeping." ”

"Is it convenient to go to your house?" Xu Shu said this and walked into the door that the neighbor had opened.

"What did you do before you went to bed?"

"Take a shower and look at your phone for a while." The neighbor didn't know what the meaning of this was, but obediently replied, "And drank a glass of water." ”

Xu Shu walked to the bathroom first, and finally stopped in front of the water dispenser.

"The water stopped this morning, and the water I just drank ran out, so I asked the water delivery worker to replace it with a new bucket." The neighbor watched Xu Shu stare at it for a long time, and opened his mouth to explain first.

Xu Shu looked at the bucket that was obviously newly replaced, took a glass of water with the paper cup next to him, and went back for testing.

The test results were very fast, and there was sleeping substance in the water, so it was no wonder that the neighbors could not hear the screams of the murderer.

Jiang Qingrui woke up at this time, and Xu Shu happened to explain his new discovery to her.

"So, there's obviously something wrong with the water delivery man." Jiang Qingrui stretched her waist widely, "Eighty percent is his sleeping pills." ”

"Most likely, it was the murderer or accomplice." Xu Shu immediately contacted to retrieve the monitoring.

At this time, Jiang Qingrui's mobile phone rang, informing that the body had been moved.

"I'll go for an autopsy first." Jiang Qingrui felt energetic after a good night's sleep.

Along with the body, there was also a biographical record of the deceased.

Song Yunsha, female.

Outsiders, who have worked in the city for more than three years, are suspected of prostitution based on chat messages and a large number of transfer records on their mobile phones.

Jiang Qingrui hastily walked through it, dressed neatly, picked up the scalpel and walked to the deceased.

After careful examination, Song Yunsha's throat cut was not a fatal injury, but a knife wound to the heart, which killed him with one blow.

There were no obvious external injuries except for two wounds.

After the autopsy, Jiang Qingrui found that the corpse had been injected with a large amount of muscle relaxant before his death, and the needle hole was in the hair, which was not found at the first time.

Because of this, her struggle was so small, Jiang Qingrui thought to herself, she thought that Song Yunsha had no strength after fighting the murderer.

Jiang Qingrui took the autopsy results to Xu Shu as soon as possible, and Xu Shu did not analyze them after reading them, "The family of the deceased is here, go over first." ”

Song Yunsha's parents sat in chairs, their faces full of impatience.

Mother Song looked left and right, "What's going on with this dead girl, but it's not okay." ”

Qiao Linlin was sitting opposite the two of them at the moment, "Do you know where your daughter has been recently?" ”

Mother Song frowned after hearing this, as if she had heard something incredible, "How do I know where she went, it has something to do with me." ”

"She did such an unsightly thing, and she had the face to come to the police station." Song Mu's spitting spitting squirted on the table, obviously she knew what Song Yunsha was doing.

"Officer, if you have a fine to pay, please don't come to us." Father Song hurriedly drew a line, "We are us, she is her, and the well water does not interfere with the river water." ”

"Yes, yes." Mother Song knew that this was the point, "I haven't been in touch for many years, if I didn't say that we must come, I wouldn't come!" ”

The people next to him can see the contradiction of this family.

Qiao Linlin was unmoved by the words of Song's father and Song's mother, "Your daughter has passed away, and I came to inform you today." ”

Qiao Linlin took out a piece of paper, "After you sign it, you can take the body back." ”

Hearing what Qiao Linlin said, Mother Song's face was full of shock, grabbed the paper, and read it carefully.

"She actually ......" Song Mu spoke, who was silent for a long time: "Also, I owe a bunch of romantic debts and deserve it." ”

Song's mother and Song's father did not discuss, and their attitude was unanimous, refusing to clean up for Song Yunsha.

Mother Song said before leaving, "Doesn't she often linger on the beds of several men?" ”

"Just let his regular customers collect the corpse, we are not responsible for this."

Xu Ying was getting more and more angry while listening, and wanted to refute a few words like her own flesh and blood, but was stopped by Jiang Wu.

Jiang Qingrui followed Xu Shu back to the office.

Xu Shu took out a blank piece of paper, and Jiang Qingrui immediately understood what he was going to do.

Before the profile began, Jiang Qingrui preemptively said her guess.

As for the archives, she asked for the files of the 'Butcher on a Rainy Night' ten years ago.

"I think it's a premeditated parody crime."

Jiang Qingrui took out photos of the two cases ten years apart, "Although there are the same doll silk threads and alarm clocks, there is still a big difference between the two." ”

"Ten years ago, the report did not mention what tools and processes the murderer used, but only the discovery of the scene."

"'Rainy Night Murderer' is to inject the drug and make the deceased look at the clock and feel his blood slowly flowing."

"But I heard a scream, and I speculated that the murderer intended to imitate it, but I found that someone was arriving immediately, so I was unwilling to be in pain, and I screamed loudly."

Jiang Qingrui said her speculation, and Xu Shu nodded.

At the same time, he slowly sketched the prototype of a person on paper with a pen, who is more than one meter tall and has mental illness, and according to the cleanliness of the scene, accompanied by obsessive-compulsive disorder......

Xu Shu's movements were very fast, and he immediately drew a human figure, and at the same time made multiple copies and distributed them to other policemen.

Jiang Wu pushed open the door at this time, "Team Xu, we have found the water delivery man, and the interrogation has been completed according to your instructions." ”

"The result?"

Jiang Wu shook his head, "He didn't say why he put sleeping pills in the water, but judging from the time when the deceased committed the crime, he had an exact alibi at that time." ”

Jiang Qingrui was disappointed for a moment, and sure enough, this matter was not as difficult as she expected.

The clue is broken, and the two are ready to start with the work of the deceased.

According to the chat records on Song Yunsha's mobile phone, the two touched the red light district, where there are many people and the security is lax.

Xu Shu followed Jiang Qingrui to find Song Yunsha's place of work and found the person above Song Yunsha.

Old bustard, you were so frightened when she saw the police officer card that she hurriedly cooperated with the interrogation, she only knew that the last guest Song Yunsha received was a short man.

At the same time, he was frightened, for fear that Xu Shu would give him a pot.

"It's very likely that a gang committed the crime." Xu Shu speculated.

"But the owner obviously loves dogs, and if his companion kicks the dog to death, he will definitely not accept it."

Xu Shu's speculation was overturned.

"Could it be, the dog owner is dead."
