crime scene

"Judging from the footprints extracted at the scene, three of them belonged to the family of three, and the other group was high-heeled shoes. By comparison, it was found that they belonged to Chang Anyuan's outsourced lady, named Yang Lili, and the other group was men's size 39, leather shoes. Belonging to Zhou Shufang's lover, named Li Yanan, the third set of 41 yards, the affiliation is unknown, it is very likely to be a criminal suspect, assuming that this group of footprints is really a criminal suspect, then his height is Chapter 11.78, and the error is not more than 5cm, no murder weapon was found at the scene, but no kitchen knife was found in the kitchen of the victim’s home, and the suspect may have taken him away from the scene. In addition, there was no sign of damage to the door, and no special fingerprints were extracted from the door lock. The suspect should have been let in. Or there is a key. There is no sign of being tampered with in the room, and there is no loss of any property." Zhang Yitian breathed a sigh of relief after finishing his report, and sat back in his seat.

The next one was Chu Duanyu. He cleared his throat and did not stand up. This was not a privilege. It was because Xie Qian never said that everyone should stand up and report during a meeting, but this group of people thought too much.

Chu Duanyu once asked Xie Qian this question in private.

Because Chu Duanyu has been scolded the most, she also has the best relationship with Xie Qian in private. Although I don't know what kind of logic this is, facts are facts.

Maybe it's because Chu Duanyu is a jerk, and if he doesn't seek abuse for a day, he will feel uncomfortable all over?

"I'll just talk about the conclusive information." Chu Duanyu picked up the report he had summarized, "In the first case, both Chang Anyuan and Zhou Shufang died of excessive blood loss, that is to say, they were When she was alive, her legs and hands were chopped off. The girl had a knife wound 8 cm long and 0.6 mm deep on her neck. Her throat was cut first and her ribs were taken after she died. All three of them had different degrees of physical damage Combating injuries, combined with the scene, there should have been a fight at the time, and the methods used by the suspects can no longer be described as vile and cruel, and their bones were removed and made into this weird... thing,"

Chu Duanyu pointed to the photo on the whiteboard and said, "The suspect polished the woman's hand bones, the man's leg bones and the daughter's ribs, stitched them together, and waxed this dagger-like thing. The cuts were smooth and even. He made He was very serious when he was doing it, as if he was polishing a work of art. However, judging from the wounds on the girl's body, although the suspect has some basic knowledge of anatomy, he is not proficient in the methods. He may be self-taught. The wounds of men and women The place is uneven and chopped off abruptly. According to my experience, the murder weapon is likely to be a kitchen knife, machete, ax and the like. The kitchen knife lost at the victim’s home is likely to be the murder weapon. There is no suspicious substance in the blood. Scraps of his bone knives were found in the sink...bone scraps and carrion."

After listening for a long time, Xie Qian could only come to a conclusion, this, this grandson is definitely a pervert.

As for how the suspect entered the victim's home, how he subdued the three of them, and what kind of hatred he had with the family, all are unknown. We can only hope for the last 24 hours of the victim's life.

"Photon, what's going on with you?" Xie Qian asked.

Gao Zhuonan once had improper relationships with many women, including colleagues, subordinates and even students. His private life was chaotic and disorderly. He once caused a female student to have an abortion, but his academic research is still rigorous.

After pathological examination, it was found that he was killed by intravenous injection of Agkistrodon venom. The needle tube used was left in the garbage tray at the scene, and a small amount of venom remained in the needle tube. There are many types of Agkistrodon halys.It can be used as wine or medicine, and is very common in plain areas.

He died on the night of September 9, and no footprints, fingerprints or other traces were found at the scene.

Doubtful as above.

The first team spent nearly a week investigating and screening the interpersonal relationship around the victim, especially focusing on monitoring the third party, tracking, mobile phone monitoring, positioning and other means that can be used, it is not incompatible The standard for committing a crime is to have an alibi.

No clue, no progress.

The whole body is in a state of desperation.

However, at this time, a third case occurred

Monday, February 9, sunny.

It rained all night last night, and the team members haven't closed their eyes for nearly a week. Although the criminal policemen are in good physical condition, it is very likely that they will die suddenly if this continues, so Xie Qian gave him a day off and went back to rest.

After returning to the dormitory, I fell asleep and slept for about 20 hours.

But before [-]:[-] a.m. on Monday, the police stations in the surrounding counties of Shishi City reported that there was a murder case.

Afraid of what to come.

Xie Qian could only take someone to drive to the scene of the crime immediately.

The victim was tied to a big tree by the river, his mouth was sealed with rubber strips, he was thin, and there was a 4cm long and 0.5mm deep cut on his wrist, no doubt he was drained of blood, the bright red blood was low In the soil, it was absorbed by the big tree.

There was a dagger stuck in the root of the tree. The blade was brass in color. The edge of the knife was identified to be consistent with the wound on the wrist. The suspect left its crime tool at the scene.

What the hell is a knife?

Xie Qian scratched his head impatiently.

The heavy rain last night washed away the crimes, leaving no valuable clues at the scene except the dagger.

"Dali, take a few people to stay and visit the victim's surroundings, and the rest will go back to the team."

The deceased Sun Dashu, male, 32 years old, a native of Gaocheng, entered Shishi City at the age of 20 to work, married a wife and had children at the age of 25, and his wife was also a local. Sun Dashu worked outside all the year round and seldom came back. Nei discovered the ambiguous text messages between him and others, and Sun Dashu left home angrily after a big fight.

It was raining that night, and my wife didn't go out to look for him out of anger, thinking that he must have returned to the city.

But the children who went to play by the river the next morning found Sun Dashu's body and notified the adults to call the police.

This is the third dagger-related case. A dagger was left by the suspect at all the scenes, but there is no connection between the three groups of victims. All the victims in the group had disordered private lives, cheated on each other, and messed with relationships.

Planned and targeted serial killings.

"Joint investigation!"

These three cases are not without breakthroughs. The first one can start with surveillance. However, the community surveillance is cleaned up every week. The police surveillance extraction was one step late that night. The surveillance data has been automatically deleted, and the coverage has been eliminated. Zhang Yitian’s technology can’t be retrieved. kind of.

The breakthrough in the second case was the snake venom. The suspect would not go to the mountains to catch the snake by himself. The danger is too high. If he is bitten, he will have to go to the hospital for treatment. Leaving clues is not worth the candle.

There is a contingency in everything, just in case the suspect is stupid?

Visiting hospitals in major provinces, cities and counties found nothing except an old man who was bitten when he went up the mountain to chop firewood.

What year has it been to go up the mountain to cut firewood? !
