Replace the evil way

He Wei might be gay, which was not mentioned at all during Xiang Yang and Ke Dongrui's investigation.Including his parents, they didn't mention any related information, and asked them why He Wei didn't live at home. They just said that the child is old and has his own ideas, and they can't control them if they want to move out.

However, Cheng Zesheng is sure that He Lu definitely knows something, and his reaction to his brother may be due to this aspect, so we need to focus on investigation.Xiang Yang looked at Cheng Zesheng curiously: "Deputy Captain, do you think He Wei's death is related to his brother? But his brother was away for a meeting two days ago, so he didn't have time to commit the crime at all."

"It is not necessarily homicide, and the possibility of buying and instigating the murder is not ruled out." Cheng Zesheng held He Wei's information, "The social relationship of the deceased can be summarized on a piece of paper, and the acquaintances around him can be counted with one hand. The breakthrough Very few, so any possibility should not be let go."

Cheng Aiyue stood at the door of the office and knocked on the door: "Deputy Captain Cheng, this is the on-site trace inspection report."

Xiang Yang trotted to fetch it, and Cheng Zesheng asked, "Did the skin tissue test come out?"

"Brother, Xiaoliu just sent the sample, and it needs to be extracted first, then typed, and compared. Even making coffee is not so fast."

Cheng Zesheng opened the report, read two pages, and frowned: "All the fingerprints extracted at the scene are his? The ones on the murder weapon?"

Cheng Aiyue nodded: "That's right, including the skin flakes left in the cracks of the hemp rope, I have carefully identified it, and there is no other person's DNA."

At the back of the report was a marked picture, clearly depicting each fingerprint on the hemp rope of the murder weapon, Cheng Zesheng handed the picture to Xiangyang: "Come on, these are all the fingerprints of the same person, excluding Zile, how do you think it should be explained? "

Finding out that Cheng Zesheng was going to train/teach his apprentice again, Le Zhengkai watched with interest, and Ke Dongrui also sat down. Cheng Aiyue went back, and she had to hurry up to test the skin tissue, so that the deputy Cheng would not have to rush again.

Xiang Yang became nervous for a moment. According to the position of the fingerprints marked on the picture, he clenched his fists and gestured forward and backward, expressing his own opinion: "If it is confirmed that it was a homicide, the murderer should hold his hand and then strangle him to death..."

"This is not true." Cheng Zesheng interrupted him, "If this method is used, his knuckles and the back of his hands will inevitably leave marks of pressure. If the murderer is strong enough, he will even fracture his phalanx. But his hands are in vain. It's clean, except for the skin tissue left by the struggle in the fingertips, there is nothing unusual."

Xiang Yang rolled his eyes: "The murderer wore gloves all the way to commit the crime. He first strangled the person to death, and then gave the victim the rope to leave his fingerprints."

"Why let the victim hold it?"

"...Making us the police mistakenly believe that it is self-strike?"

"First of all, after a person's death, the muscle tension disappears, and the whole body becomes slack and soft, so it is impossible to leave such clear and deep fingerprints. Including the skin tissue in the hemp rope, those are marks that can only be rubbed with bare hands." Cheng Zesheng spread out from the table. A photo of the morgue was picked from the on-site photos. "The second is the deviation of the fingerprint position. You can use his hand gestures to pick up a rope and see what kind of fingerprint shape will be left."

Le Zhengkai frowned: "Xiao Xiangyang, the rope was held in his hand. If the murderer wanted to create the illusion of self-stranglement, why did he take it off? Putting it directly around the neck will not arouse suspicion."

Ke Dongrui sighed: "The murderer didn't want to hide it at all. He killed people openly, so I guess the gloves are useless."

Looking at the three seniors, Xiang Yang twisted his little hands together nervously, and racked his brains to say: "...Use fingerprint film?"

"Starting to think wildly?" Cheng Zesheng took the report and tapped him on the head, "Is there any reasonable explanation?"

Xiang Yang shook his head. Ever since he followed Cheng Zesheng, he felt that he had spent a few years studying in the police academy for nothing, and that little bit of knowledge was useless in complex cases.Cheng Zesheng gave him the information and asked him to go to the physical evidence department to take a good look at the rope, and then go to the forensic department to carefully observe the corpse. Jiang Tan's autopsy should not be over yet, and he can catch up with the exciting part now.

Xiang Yang had a bitter face, as if he was about to go to the execution ground.Ke Dongrui closed the files and went to focus on investigating He Lu. Cheng Zesheng asked Le Zhengkai, "Have you been to the victim's house?"

"I've been there now, and he lives in a small rental house. The door locks are intact, and there is no sign of the house being tampered with. The bank cards and valuables are all there." Le Zhengkai said, "I always feel that this case The method is too strange, go to the bar and look for it, maybe you can find some unexpected clues."

"I'll go to the bar, and you can take someone to the scene again." Cheng Zesheng picked up the car keys, "Look carefully again, don't miss anything."

"Just now you didn't explain the confusion to the apprentice, did you realize that based on the evidence we have, the scene you speculated can't be established?" Le Zhengkai suddenly approached and lowered his voice, "Zesheng, do you believe that there are ghosts in this world?"

"I don't believe it, I only believe that someone is making trouble."

Avenoir is a music bar located at No. 36 Xu'an Road. This bar is open from [-]:[-] pm to [-]:[-] am, but after [-]:[-] pm, it becomes a gathering place for the special kind of people who love men.A few years ago, Cheng Ze caught a suspect who couldn't control his lower body. While he was on the run, he even dared to have a one-night stand and got blocked in the bathroom of a bar.

The decoration and style of this bar are different from general entertainment venues. Many bars like to use harsh and loud music to ignite the atmosphere, and all the dirt is covered by punk and rock.But Avenoir has no ambiguous dance floor, no magical crystal magic ball, and no DJ playing discs. There is only light music as the background sound in the store, which infuses this hunting/erotic place with a different artistic flavor.

As soon as Cheng Zesheng opened the door, he attracted all kinds of eyes, some were curious, others were amazed, some were admiring and some were playful.He was wearing a simple black shirt and washed jeans. The simple and low-key outfit should stand out from the crowd, but he couldn't hold back his good looks. When he sat at the bar, he seemed to have a spotlight with him, as if there was a stage where he was.

"Handsome guy, you look unfamiliar, this is your first time here?" The bartender wiped his goblet and smiled, "What do you want to drink?"

"Soda water." Cheng Zesheng looked around, "Where are you even the boss?"

"Our boss usually doesn't come until after ten o'clock," the bartender pushed the menu over. "Would you like to order a snack? There's a [-]% discount for events now."

Cheng Zesheng raised his wrist, ten o'clock, there is still more than an hour, he doesn't have time to spend so long here.Just as he was about to reveal his identity, someone sat down beside him: "Please give this gentleman a Mojito."

"..." Cheng Zesheng refused coldly, "No, we don't know each other, so keep it for your lover."

The man was stunned for a few seconds before he connected this refusal with the recent hot song, and suddenly he became interested, and put his hand on Cheng Zesheng's shoulder: "What's the point of coming here to drink soda water, you can drink whatever you want, I will please."

Cheng Zesheng was disgusted in his heart, but he was not in a hurry to drive away this greasy-faced man, and took out He Wei's photo: "Do you know this man?"

The man replied perfunctorily "I don't know", Cheng Zesheng nodded: "OK, there's nothing else to do with you, get out."

"Why, is that your boyfriend?" His tone was meaningful, "Few people who come out to play will be really emotional, so you are not cheated, are you?"

"Ha ha."

The man snapped his fingers, asked the bartender to make a cup of Long Island iced tea, and pushed it to Cheng Zesheng. His voice was lowered, and his tone became ambiguous and deep: "It's all about fast food love now, and it's not about the heart..."

Cheng Zesheng's gaze scraped across the wall of the Long Island Iced Tea cup, and then onto his face.Of course he understands that this is a tacit hint, drink my wine and come with me tonight.So Cheng Zesheng stretched out his well-knit hand and touched the wall of the cup. The man's eyes lit up with joy, and he suddenly heard: "Have you chosen the place yet?"

"You can go anywhere you want."

"Oh, that's it." Cheng Zesheng casually took out his police ID and threw it on the bar, "Just go here, I know you well."

The man's expression turned ugly in an instant, and he looked at Cheng Zesheng. He never expected that he would be a policeman, and the image of the uncle policeman in his impression was too different. With his appearance and figure, he thought he was some internet celebrity or model.

The man smiled compensatingly and dodged despondently. The bartender was also dumbfounded. Cheng Zesheng put away his ID and asked again: "Your boss doesn't come until ten o'clock?"

"I, I'll call right away, just wait a moment."

In less than half an hour, a man in a beige windbreaker, as gentle as jade, appeared: "Officer Cheng, long time no see."

"It's been a long time, maybe two years?" Cheng Zesheng pointed upstairs, "Look for a place, there are too many people here."

Lian Jingyuan, the owner of the bar, ordered tea to be brought up, and he led the way. It wasn't until he reached the second floor that he wondered why Officer Cheng was looking for him today.

"Do you know He Wei?"

Lian Jingyuan nodded: "He is a senior in my university."

"He's dead." Cheng Zesheng pulled out a chair, "Strangled to death, I came to you to know something about him."

After sitting down, Cheng Zesheng raised his head, only to find that Lian Jingyuan's movements froze, and he stood there motionless.His delicate cheeks turned pale, and he asked softly, "...when did it happen?"

"On the night of the 14th."

"Impossible." Lian Jingyuan bit his lip and said firmly, "At one o'clock that night, he even came to the bar to look for me."

Jiang Tan was about to go to bed when he received a call from Cheng Zesheng: "He Wei doesn't have alcohol in his stomach?"

"No, the last meal he ate was rice, isn't it in the report?"

Cheng Zesheng was reading the report, frowning deeply: "Have you done a blood test? Are you sure?"

"You're questioning my professionalism," Jiang Tan was puzzled, "I can't find out if I've been drinking or not? I'm a ten-year old forensic doctor!"

Cheng Ze was unwilling to give up: "The time of death? I think you wrote about 3:[-] in the morning. Is it possible that you made a mistake?"

"!" A carp in Jiangtan sat up straight, "Cheng Zesheng, I'm angry, you are really insulting my level. There was no air conditioner or ice cubes at the scene, and no measures were taken on the corpse to affect the time of death. Ten years of reputation guarantee, nothing goes wrong!"

"Beep, beep", the other party has hung up.

"Fuck, what's wrong with you!" Jiang Tan dropped the phone and fell asleep with his head covered in anger.

Cheng Zesheng carefully read the autopsy report from beginning to end, as well as the skin tissue report. After comparison, it was also He Wei's DNA, but there was no matching scratch on his whole body.

He slowly closed the report, even Jing Yuan's words were still engraved in his mind.

"It was one o'clock at that time. The senior was drunk and came to the bar to find me. He was very depressed and sad. We chatted for a while before leaving at three o'clock. I remember it very clearly."

According to Lian Jingyuan's testimony, He Wei was unable to rush to the mansion to be killed no matter what.Not to mention the accidental deviation of the time of death or Lian Jingyuan misremembering the time, but what about the reconstruction of the scene?

In the morning, while Cheng Zesheng refuted Xiang Yang, he was also speculating about the crime scene in his mind.The number of strangle marks on He Wei's neck is only one circle, and there are no knots. In order to be quick, precise and ruthless, the murderer must do his best to kill him.Therefore, the traces on the hemp rope reflect the most real crime situation, and all the fingerprints left behind are the ones that have no time to cover up and do not want to cover up.

However, the test results showed that they were all dangerous.This is the reason why Cheng Zesheng has been unable to reconstruct the scene very well. According to these evidences, the picture that emerges in his mind can only be that He Wei strangled himself to death behind his back.That's why Cheng Zesheng asked Le Zhengkai to go to the scene again, trying to find other evidence that could overthrow this idea.

Impossible to sin.

Cheng Zesheng leaned back, leaned against the small sofa, and looked up at the ceiling.

There must be some undiscovered evidence missing. There is no impossible crime in this world.
