At 0:30, Dong'an City Police Station.

"What's the matter with me in such a hurry?" Xu Tian asked.

"Just before I was editing a case file from four years ago, the police officer I was sorting through the case found another case that I was very concerned about. I think it's very important for you to see it in person. ”

"What is it?"

"The same case was four years ago, just seven days after the death of the girl who committed suicide, a horrific murder occurred next door to their house, and the person involved was Hailan and their family!"

"Hyland? Was the case solved at that time? ”

"Look at the case file!" Lao Chen solemnly handed the case file to Xu Tian.

In the early morning of August 10, 2013, a male corpse was found in Hailan's home, and the person who found the body was Hailan's mother.

Around 5 o'clock in the morning, Hailan's mother got up to cook, and when she opened the bedroom door, she found a middle-aged man lying on the coffee table in the living room.

When the police arrived, the man was dead, the cause of death was a heart palsy, and the time of death was between two and half past two in the morning.

At that time, the most puzzling thing for the police was that a large amount of flour was sprinkled in the living room of Hailan's house, which continued to the door, and there were no footprints of a dead man on the flour, but there was a row of relatively small footprints, judging from the shape of the footprints, it looked like a teenage girl.

"What the hell is this? It looks like the little girl next door has come back to kill the first seven! Xu Tian said.

"That's right, but this murder has been solved, and I haven't been promoted to team leader at that time, and I was sent to support the mission, so I don't know much about this case." Lao Chen said.

"And who was the person who solved this case at that time?"

"It was Dr. Lin who helped the police solve this case."

"What? Dr. Lim? ”

"Go ahead and look at the case!"

Four years ago, on the day of the crime, the police investigated the identity of the man who died, an unemployed man who lived in the next building.

Dr. Lin, who assisted the police in handling the case, also quickly solved the case, and the murder method was not complicated, what made Xu Tian feel frightened was the psychology of the deceased.

The truth of the case given by Dr. Lin is that the man had deformed mental thoughts about the girl next door who died a week ago.

The murderer was identified as the father of the girl who committed suicide a week ago, and through the police interrogation of the girl's father, the girl's father soon confessed all the crimes.

As for the method of murder, the murderer used his daughter's mobile phone to send a text message to the deceased the night before, and the content of the text message made Xu Tian feel a chill down his spine. "Come next door to my house at two o'clock in the morning, today is my first seven, if you put on my shoes and come next door to my house to find me, I will go with you."

"What kind of logic is this? Did the deceased believe it? Xu Tian said in surprise.

"As you can see, this incident is indeed true, the deceased had a serious mental illness, before the girl committed suicide, the deceased had many serious harassments of the girl, and the police also knew about this matter, and the police had conducted many mediations, but because the other party had mental problems, we couldn't do anything." Lao Chen said.

"Yes! What can be done! Mentally ill persons are a vulnerable group in law and should be protected. Xu Tian said.

"It is precisely because of this case that the police have also closed the case of the girl next door who committed suicide, and the girl next door committed suicide because she couldn't stand being harassed by a mentally ill person."

"Judging from all the signs, there is indeed a possibility, but what the truth is, it has to be confirmed by strong evidence."

"The case is closed, I don't think there is any problem, but I am a little surprised by the people involved in this case, if it is a coincidence, it is too coincidental!"

"That's right, four years ago, Dr. Lin solved a murder case related to a girl who committed suicide, and Dr. Lin induced me to witness a similar death of a girl last night.

"That's why I came to you to discuss this with you."

"How did the father of the girl who committed suicide end up sentenced?"

"Because it was intentional homicide, the death penalty has been carried out."

"If this murder method is not for the murderer to take the initiative to admit it, I think as long as he grits his teeth and dies, the police will not be able to do anything about him."

"But he admitted it, and the reason was also written in the case file."

"I saw it, the murderer finished avenging his daughter, so I don't want to live anymore. The murder method was that the murderer sneaked into the neighbor's house in the middle of the night, sprinkled flour in the living room, carried the flour bag to the living room, and then began to gradually sprinkle flour on the door, and finally closed the door of the neighbor's house and exited by himself. The murderer asked the deceased to put on his daughter's shoes and enter the neighbor's house, and then the murderer pasted the daughter's photo on the neighbor's window through the window of his house with an extension rod. ”

"The deceased had a history of heart disease and mental illness, and the police did find out that the deceased did receive a text message from the murderer on his daughter's mobile phone the night before the crime, if it was a normal person, he would definitely not believe that the deceased sent a text message, but the deceased was a mentally ill person, and it is logical that he can believe it."

"The whole case seems to be fine, and what interests me the most is how the killer recovered the shoes worn by the deceased's feet."

"The shoes were snatched from the feet of the girl who committed suicide before, and the whole community knows about the harassment, and it is because of these previous harassment incidents that the truth of the case has become more convincing."

"The case file states that the murderer opened the door of the neighbor's house again and recovered the shoes on the deceased's feet, when the deceased's feet were facing the doorway, and the murderer used the elongated pliers he made to remove the shoes on the deceased's feet."

"That's right! The killer confessed, and the police did find the elongated pliers in the murderer's home. ”

"But do you think this method of recycling shoes is real?"

"I can't tell if it's true or not, anyway, I think it's a little strange, after reading this case, I always feel that the modus operandi is a bit too simple, but the murderer admitted all the facts of the crime, and the police can't do anything about it."

"What's strange is not only the collection of shoes, but also the death posture of the deceased, whether he is lying on the coffee table of Hailan's house, and the case file does not indicate what kind of posture this lying is, whether he is lying with his head up, or lying on his side? Or is it lying on your stomach with your head down? ”

"This problem was also suspected by the former team leader who handled the case at that time, because the position of the coffee table of Hailan's house in the living room and the position of the deceased lying on the coffee table at that time really made people suspicious, and the police also took photos when they felt the scene, and they were in the file bag, you can see it."
