"This case is exactly the same as when Wang Lin was killed, judging from the scene, it should be a suicide, right?" Lao Chen said.

"It's hard to say, there are different places, I remember that the case file of Wang Lin's murder is very clear, when Wang Lin was hung upside down outside the window, his face was facing outward, and the face of the victim of this murder was facing inward." Xu Tian said.

"It's really weird."

"Was the murder weapon found in the grass downstairs?"

"Yes, right outside the window of the psychiatric clinic."

"The same blade?"

"That's right, the blade of a disposable razor."

"What are the results of the murder weapon?"

"This time there are fingerprints of the victim on the blade, which have not been wiped."

"That would explain the problem, this time the murderer did not have access to the murder weapon."

What do you mean by that...... This case is also a homicide? ”

"It's impossible to say for sure, but at least there have been four cases so far, except for the place where Xiao Shuang was killed, unlike the other three cases, the victims in the other three cases were all hung out of the window. But if it is the same, only Wang Lin's case is more similar to this case, in which the victim in the high school case was not cut throat, but was strangled to death by suffocation. ”

"Yes! The four cases are just similar, but they are all different. ”

"This shows that the murderer has no magical powers, and the murderer has no way to make every case exactly the same, but the only common denominator in each case is that the victim hangs to death, which is the key to solving the case."

"That's true, through my years of experience in handling cases, the chance of vendetta is relatively high."

"What you said is not unreasonable, but at present we still have too little information, I suggest that we act in two groups, and you immediately go back to the police station to investigate whether there has been a similar case in the past five years."

"What about you?"

"I'm going to visit everyone involved in the case."

"I see, you have to be careful."

"Don't worry! I'll be fine, but how about what I asked you to do tonight? Xu Tian asked in a low voice.

"Everything is in plan." Lao Chen whispered in response.

After separating from Lao Chen, Xu Tian returned to the psychological clinic, originally Xu Tian wanted to go to the bathroom, but the bathroom in the psychological clinic has been used.

"Aren't you gone yet? Do you want to change your mind and get treatment? Not tonight, your treatment time is over. Dr. Lim said.

"I'm coming back to tell you a word, don't bother me anymore." Xu Tian said seriously.

"The address to me has changed from 'you' to 'you', and it seems that you will only show respect to me when you ask me."

"I'm not begging you, you and I are well aware of what happened tonight, and I will continue to investigate you, at least you have been involved." After Xu Tian finished speaking, he turned around and walked towards the door.

When approaching the bathroom at the door, the person who had been using the bathroom finally walked out, Xu Tian looked at the person, it was an old man with white hair, this old man was limping and wearing a hospital clothes.

"Aren't you a psychiatric clinic here? Is trauma still treated? Xu Tian turned to Dr. Lin and said.

"He's not my patient, he's my guest." Dr. Lin said with a sinking face.

"Guests?" Xu Tian looked at the old man who was holding on to the wall and walking hard. "Then don't bother."

After Xu Tian left, Dr. Lin took out a pair of metal-framed glasses from his handbag and put them on, muttering to himself, "You haven't figured out who was involved." ”

……

After leaving the psychological clinic, Xu Tian returned to the office, and at this time Sitong and Siyan had already returned early.

"Didn't I tell you not to come back tonight?" Xu Tian said in surprise.

"It's done, it's okay if we come back, right?" Siyan said.

"Have you removed the camera at home?" Xu Tian asked.

"It's all torn down." Siyan said.

"Well, I don't want to live under the camera every day." Xu Tian said.

"It's as if you live at home a lot." Siyan teased.

"Seems to be right! But I have a hunch that soon I will be able to enjoy the blessings at home. ”

"You have a decadent mentality, it's not okay for us to have this kind of thinking at our age."

"If there is no case to find the door, what is the difference between me and Xiang Qingfu?"

"You're so confident?"

"What? Does Siyan like this busy state? ”

"I ...... I don't like it! ”

"Okay, I'm still going out tonight, and now that you're back, I'm relieved."

"What else are you going to do?"

"The case at hand is not yet solved, and the number of victims is increasing, this matter cannot be delayed, and I must solve the case as soon as possible."

"He also said that he would enjoy the blessings! I think you're born to be busy. ”

"Am I busy? Compared to someone, I think I'm pretty laid-back, hahaha......"

"Xu Tian......" Sitong walked out of the kitchen with three bowls of porridge.

"Sitong, I've been busy these days, I almost forgot the most important thing, I'll go to the hospital with me at eight o'clock tomorrow morning, I've already contacted the doctor, and I'll take you to treat your leg injury tomorrow." Xu Tian said.

"I feel like my leg injury is getting better."

"Go check it out! I'll come back tomorrow morning to pick you up. ”

"Are you going out tonight?"

"Yes! I'll be back tomorrow morning. ”

"Drink a bowl of porridge! It's cold outside. Sitong picked up a bowl of porridge and handed it to Xu Tian.

Xu Tian drank it in a big gulp, put down the bowl and left the office.

Buzzing......

Lao Chen called.

Officer Chen...... How's it going? ”

"I found out that there was a suicide four years ago, which is similar to the four recent cases."

"Who is the victim?"

"A fourteen-year-old girl in the flower season."

"Can you send me the case file?"

"Yes! Then you wait, by the way, I have one more thing to tell you, tomorrow morning, Mr. Jin's memorial service will be canceled. ”

"Got it, I didn't plan to go, I'll wait for your email, goodbye!"

Doodle......

Xu Tian hung up the phone in a hurry, and about ten minutes later, Lao Chen sent the case file.

The 14-year-old girl, who died four years ago, committed suicide at home at night, and the girl's father found her dead the next morning, her left foot tied to a radiator, her body suspended outside the window, her throat cut, and she died of blood loss. The murder weapon had the girl's fingerprints on it, and blood stains were also found on the windowsill of the girl's house, so it was finally concluded that the girl committed suicide.

Seeing this, Xu Tian called back Lao Chen's phone.

Officer Chen...... This case is so important that I recommend that the family of the girl who committed suicide four years ago be investigated immediately. ”

"I understand! I'm going to do it right away, but now there's an emergency, so you come to the police right away. ”
