Detective: Start with capturing and retrieving the dog

Chapter 121 Preliminary Profile
"Lianhuan...is it the same as the time at Mount Wutou?" Hu Chen murmured to himself in distress.

"Wrong, it's much more difficult than the time at Wutou Mountain." Han Xin shook his head, "Although the murderer at Wutou Mountain is also a serial murderer, at least he is a normal person with normal logical thinking, so his actions are easy to deduce."

"Well, anyway, let's go to the scene first." Huo Gang said with a sigh.

Then the people in the car quieted down and waited silently to reach their destination.

Taking advantage of this time, Han Xin closed his eyes and thought about whether the prisoner made any mistakes.

But at least judging from the clues Huo Gang gave them, it doesn't exist. He has to go to the scene to see if there are any details that the police have missed, so that he can confirm whether he can continue to investigate.

Soon they entered the range of Shiji City. Although it is not far from Beichang City, it is a fourth-tier city. It is obvious that the development of all aspects is much worse than Beichang City.

In addition to the relatively prosperous downtown area, many communities on the second and third ring roads are very dilapidated. Most of the cameras are very dilapidated, and some of them are obviously not turned on. It is obvious that the cameras were installed for errands, just like a blind man beating people.

First, they came to the Public Security Bureau of Shiji City. Huo Gang and Lu Wenbo wanted to communicate with the local police, so Wei Bin and Hu Chen drove Han Xin to the crime scene to check the scene.

This is a residential area on the third ring road. It is an old housing area, or a tube building in the 70s. Outside is a [-]-meter-high concrete wall, and there are two surveillance cameras at each entrance.

"The houses here are really cheap, only more than 4000 yuan per square meter..." Zhao Linshan muttered, "I guess it will be even cheaper in the future."

"This place is a bit like the place we lived in when we were young, right?" Han Xin touched Zhao Linshan's head and asked.

"Yeah, it's just as broken..." Zhao Linshan rolled her eyes, "I still remember that alley in your house was scary dark at night, and the ceiling was full of mice and cockroaches. I didn't dare to go back at night, so I could only sleep with you."

"This is called heaven and reincarnation, and you still came to sleep with me in the end." Han Xin kissed her on the top of the head.

At the moment, there are still many people in the community discussing the murder outside, but everyone is basically complaining that the occurrence of the murder will further drop the housing prices here, and no one is worried about their own safety.

Han Xin followed Huo Gang to Room 802, where the incident occurred. Although this place has been sealed by the police, the neighbors still live here, and there seems to be no taboo.

Most people who live in this kind of community don't care about these things. After all, what could be more terrifying than being poor?
"Mr. Han, please." Wei Bin raised the seal and signaled.

Han Xin bent down and entered Room 802. This house has one bedroom, one living room, one kitchen and one bathroom. It has been decorated and has ready-made furniture. It is very suitable for singles or young couples.

There was no sign in the house after entering the door, which meant that the police found no substantive clues, but when they walked into the bathroom inside, a human figure was marked by a white line on the ground.

Judging from the posture, Lin Shuang was lying down on the ground, and the wounds were all on the front.

Han Xin closed his eyes and recalled Lin Shuang's autopsy report. There was a circle of marks near her mouth, which had been sealed with tape. Most of the wounds were scattered. The real fatal one was the stab wound in the heart.So it can be speculated that the previous dozens of knives were for torture, and the last one was fatal.

Han Xin looked around in the bathroom again, the place still retains its original appearance at that time.

Han Xin came to the window of the bathroom, opened the curtains and took a look: "The window of the bathroom is closed and the curtains are drawn, but there is no place to see here from the window, why close the windows and curtains?"

Then, Han Xin returned to the bedroom and scanned around with his eagle eyes: there were no highlights.

After walking around the room, Han Xin didn't find anything substantive.But the murderer is also a human being, and he must have made some mistakes.

"Where is the easiest to be ignored, where is the blind spot..." Han Xin said to himself, covering his forehead.

After thinking for a while, Han Xin thought of the answer, he turned around, looked at the open door, and closed it.

Sure enough, there was a bright spot here. He lay down on the ground and looked carefully, picking up a small piece of fiber from the bottom of the door.

Because this wooden door is relatively old, the bottom of the door has become a little rough, and there are some raised wooden thorns, and this piece of fiber is hung on the wooden thorns.

At this time, his "knowledge reserve" began to prompt again: this is because the gravity of the door caused the bolt to loosen, so the door was slightly tilted downward, so that when the door was opened and closed, it was easy to rub against the ground below to produce wooden thorns.

Of course, the wood thorn is not the key, the key is the small piece of fiber left on the wood thorn.

"Ashin, what did you find?" Zhao Linshan came over and asked curiously, which also attracted the attention of Wei Bin and Hu Chen.

"It's a small piece of fiber." Han Xin explained, "It may come from the clothes or the blanket. It doesn't matter. The important thing is that this case was not done by a professional killer, but by a psychopath with antisocial personality."

"Why?" Hu Chen asked puzzled.

"Let's see what the murderer did." Han Xin said, pulling Zhao Linshan in front of him, "Shanshan, you will play the victim and I will play the murderer. It will be easier to explain."

"Okay!" Zhao Linshan smiled happily, "What should I do?"

"You are a real estate salesman, take me to see the house." Han Xin replied, "Go to the bedroom first, then to the kitchen, and finally to the bathroom."

Zhao Linshan brought Han Xin to the bedroom: "This is the bedroom..."

When Zhao Linshan was about to continue the introduction, Han Xin interrupted her: "I came here, and I didn't do anything to you, everyone remember this." Then, Han Xin turned to Zhao Linshan: "Shanshan, you continue."

Zhao Linshan brought Han Xin to the kitchen again: "This is the kitchen, we have..."

"The reason for not doing anything in the kitchen is the same as the reason for not doing it in the bedroom." Han Xin explained.

Finally, Zhao Linshan brought Han Xin to the bathroom, and said listlessly, "This is the bathroom."

However, when Zhao Linshan was heading towards the bathroom, Han Xin covered her mouth from behind while her back was facing him.

"At this time, I took action." Han Xin explained, "I subdued her first, maybe knocked her out, or stunned her with a drug, then I sealed her mouth and tied her hands. At this time, I was not in a hurry to complete the task and leave, but was ready to enjoy the prey in front of me, so I closed the bathroom window and curtains first, and then..."

Han Xin turned his head and came to the living room: "Block the door to prevent the sound from coming out."

After finishing speaking, Han Xin returned to the bathroom and pinched Zhao Linshan's neck: "At this time, I can start to enjoy my prey. Her mouth was taped, and she could only make a few hums, but the door was blocked and the windows were closed, so it was difficult for her voice to come out. So she could only die of despair under the torture of the murderer."

Zhao Linshan pinched his face unconvinced.

"Of course, this is just a simulation to emphasize his reason for committing the crime in the bathroom. Maybe he directly controlled the victim as soon as he came in." Han Xin continued: "Then, why did he choose to commit the crime in the bathroom?"

Hu Chen interjected: "Because it's closer to the water source, it's convenient for me to clean up the scene afterwards?"

"There may be some reasons for that." Han Xin shrugged. "But considering the preparations he made, I think it's more likely that he wants to slowly torture the victim here. His purpose is to enjoy the process. The killer will only act when he has an employer, which requires a certain degree of self-discipline, and he can't control his desire to kill before acting. The two conflict."

"And the murderer has considerable medical knowledge and knows how to stab so as not to kill a person." Wei Bin added, "This beast, the previous 40 stabs did not hit the vitals, and the stabs were not deep."

"The murderer patiently cleaned up the scene, which shows that he has a delicate mind, and he controls the victim first before committing violence, so women can do it too." Han trusts his chin and muttered to himself, "If he is not a professional killer, then he should be a local. He must have a process from unfamiliarity to proficiency. Check the previous murder or disappearance case, maybe there is a link."

But that's all, Han Xin can only profile this murderer so much, there is no more information.

The murderer is very skilled and careful now, and it is very difficult to find his loopholes in this case, so we can only hope to start from the case when the murderer was not so skilled before, and see if he can find anything, otherwise...

"If we don't find out, then we can only wait until his next victim appears." Han Xin sighed heavily, "I don't think anyone wants things to develop to that point, right?"

Wei Bin and Hu Chen shook their heads.

"Okay, then let's go and go back to the Public Security Bureau." Han Xin waved his hand, "Check to see if there are any unsolved disappearance cases or homicide cases a few years ago, and then see if we can connect them with this case."

"It's really rare." Zhao Linshan said, holding his arm, "It's the first time I see you can't reason anything."

"He is a psychopath, so you can't deduce what he will do." Han Xin replied, "Although I have reasoned logically, it may be that the truth is what Police Officer Hu said. The murderer simply thought that 'here is closer to the water source, so I can clean up the scene afterwards'."

Although little is known about the murderer, Han Xin knew that if he could not be caught, sooner or later there would be victims.

So he needs more information: "I want to talk to her current and ex-boyfriends."
