Special case investigation team V

After Tang Shi sent the special case team to the gate of the Public Security Bureau, he said he was leaving.

"Back to Lingzhou?" Cheng Jin asked.

"No, I'll be back the day after tomorrow. If you have anything to do these two days, you can call me. I know you well."

"Okay, thank you."

You Duo guessed: "Is it inconvenient for him to show up in public at the Public Security Bureau?"

Bu Huan shook his head, "No way, he's still afraid of being exposed? He's not Jing Xingzhi, he's keen to break into the enemy's interior."

"Each has his own job, and he also has his own things to do." Cheng Jin said, "Let's go."

After the special case team entered the Public Security Bureau, they greeted the people in the Public Security Bureau, took a short rest, and then started the meeting.

The people from the Public Security Bureau first introduced the case.

The first victim is Mao Xiaoyan, from Wu County. She has been in Lengjiang for four years and lives at No. 57 Neixiang Road. The place is a village in Piancheng. The conditions are not good, but the rent is cheap. Many migrant workers live there. over there.

"They're all old houses, and there's not much surveillance, so it's very troublesome to check." The captain of the criminal police, Bao Junjian, a middle-aged man with a thick beard and thick hair, said with a sigh.

Nowadays, most of the cases are handled by monitoring. Without monitoring, everyone's eyes are black.

Cheng Jin said, "Are there any clues in the deceased's room?"

"Yes, there are too many."

Mao Xiaoyan is a sex worker and often takes different people home. She was killed in her rental house 22 days ago.Before she was killed, she had sex with someone, and she did it with a condom. The condom was not in the trash can, and it was probably washed away in the stable.

Forensic scientists collected many different fingerprints and DNA from the room, but no one knew if any of them belonged to the victim.

"What about the neighbors, did you see anything?"

"We have visited and have no clues for the time being."

"Is Mao Xiaoyan's financial situation not very good?"

"It's not good. The girl from the countryside is poor. She has no education, but she is beautiful. There are younger sisters and younger brothers who are studying at home. Most of the money she earned is sent home. The murderer robbed her of the money. , I found the wrong person, this girl doesn't have much savings at all."

"You think it's robbery?" Ye Lai asked.

"It should be." The criminal police explained, "This kind of thing often happens here. Some clients are hooligans. After they finish their prostitution, they not only refuse to give money but also steal money. But those girls can't do anything about it. It is illegal for them to prostitute. , so I dare not call the police. Their business is very risky, and it is a trivial matter to be beaten and robbed of money. Otherwise, they will lose their lives like this girl."

Bu Huan said: "Why doesn't she go to work in a more formal place?"

"Regular" places employ professional security guards, and the clientele is relatively civilized. It is more secure for girls to work there than to work alone.

"She was working in a nightclub, and taking someone home that day should be a private job."

"Is that nightclub still open?" Cheng Jin asked.

"..." The people at the Public Security Bureau were silent.

The captain of the criminal police, Bao Junjian, said after a few seconds: "I am here, but I have already gone to investigate."

The crackdown on pornography is always one after another, as long as there is no word from the top, those places will remain open.

"It's okay. I'm not here to fight pornography. Don't be in a hurry to rectify it. Our first task is to find the murderer. Don't scare the snake away." Cheng Jin said.

"...Okay. But what if the murderer does it again?" Bao Junjian was most afraid of another death.

The most recent victim died seven days ago, and the murderer is likely to do it again, maybe even did it already, but the body has not been found yet.

Cheng Jin said: "Notify those nightclubs or KTV places, tell those girls to be careful and pay attention to safety, if you are really worried that your life is in danger, we can provide protection."

"...Okay." Bao Junjian always felt that something was wrong, protecting those girls?How should I put it, maybe it should be protected, but I always feel that they will be in danger, and it is mainly their own responsibility.

"How long has she been in this business?" Cheng Jin looked at the photo of Mao Xiaoyan projected on the wall, she looked very young, looking at her ID card, well, she was very young, only 23 years old.

"He came out after graduating from junior high school at the age of 16. At first, he worked in a factory, and was later brought into the industry by fellow villagers."

"How is the man? Clever?"

What is the problem?The detectives looked at each other. "Should be smart, girls in this line of work are like human beings, they talk about people when they see people, and they talk about people when they see ghosts."

"Look for her colleagues to understand her character." Cheng Jin said, "If she is really smart, why does she bring the guests back to her residence? Doesn't she know it's dangerous?"

Bu Huan's eyes lit up, "Unless the guest is a regular customer she knows, she thinks there is no danger."

Cheng Jin nodded, "You follow this matter."

Bu Huan responded: "Okay."

Bao Junjian said: "We have checked the acquaintances, and they all have alibi."

"Then let's check it again, and be careful to sail for ten thousand years. Thank you for your hard work." Bu Huan said with a smile.

Bao Junjian also smiled, "Yes, be careful."

Han Bin said: "When the murderer beat the victim, didn't he use any tools?"

"No." The forensic doctor replied, "but the victim hit the furniture and suffered injuries on the head and back. The fatal injuries were a ruptured liver and spleen and bleeding from the lungs."

"She broke seven ribs, right?" Han Bin glanced at Cheng Jin when he said that.

Yang Simi also turned to look at Cheng Jin.

Cheng Jin, "..."

The forensic doctor said: "Yes, the broken rib pierced the lung and caused massive bleeding."

Yang Simi looked at Cheng Jin, "What do you think?"

Cheng Jin laughed softly: "The world is really dangerous, you have to protect me from now on."

Yang Simi blinked, and slapped his long eyelashes slowly, he was satisfied with the answer. "Well, I'll protect you, you have to be good."

Cheng Jin, "..."

The second victim was Li Aihong, who was also a migrant worker in a small remote place. She was strangled to death in a hotel 19 days ago and had sex with someone before she died.

The hotel she stayed in was not formal, there was no monitoring, and no ID registration was required, and the front desk and waiters of the hotel were often not on duty, so no one saw who entered Li Aihong's room at all.

You Duo said: "The murderer is very familiar with that hotel. Did he make an appointment there on purpose? Did he want to murder?"

No one knows this, probably only the murderer knows his motives.

"The victim's fingernails caught fabric fibers, did you find out what kind of clothes it was on?" Han Bin asked looking at the case files.

The forensic doctor said: "We only know that it is blue cotton fiber. If we can find suspicious clothes, we can know whether the clothes are the ones that the murderer wore that day through comparison."

But now even the suspect has not been found, and there is no place to work hard with this evidence.

Bu Huan sighed, "This girl is weak, why did she only catch the clothes, she should have scratched a few holes on that man."

In this way, the murderer's DNA will be left on her nails, which will be of great help to the police in solving the case.

Ye Lai said: "Maybe the murderer is better armed."

For example, he wore gloves, a thick coat, and was very careful when committing the crime, so he was not scratched by the victim.

"Is there no medicine in the deceased's body?" Han Bin asked.

If the victim was injected with a sedative or something, the degree of resistance will also be weakened.

The forensic doctor shook his head, "No."

"That is to say, the murderer's method of killing is quite professional." Bu Huan flipped through the photos of the corpse, "But it's not at the level of a professional killer."

Han Bin said: "There is still a long way to go."

……

Zhang Mingxue is the third victim. She was strangled to death 13 days ago and then dumped in the wild. So far, the scene of the first crime has not been found.

Chen Yao was the fourth victim who died 7 days ago. She was also strangled to death. The murderer threw her in an alley.A man passing by thought she was drunk and wanted to take advantage of her, but when he started, he was so cold that he almost pissed in fear.

The two victims also had sex with others before their deaths.

"We judge that the two victims were killed by the same murderer. The strangle marks on their necks are very close, and the force is the same." There are a few bruises, which should be made by beads or knots, and we think the rope used by the murderer to strangle the victim should be a pendant lanyard or other decorations."

Cheng Jin said: "Has Zhang Mingxue lost such decorations?"

"No. That lanyard may have belonged to the murderer."

But police were unable to locate the male client, who was wearing a pendant lanyard.

"Maybe he didn't hang it around his neck, but wrapped it around his hands - many men like to wrap a few prayer beads around their wrists." Bu Huan said.

"It's not a string of beads, it's a thick string with beads on it."

Cheng Jin glanced at the black leather rope on his wrist, "What material is the rope made of?"

"Braided rope, like this." The forensic doctor handed Cheng Jin his mobile phone to look at.

Cheng Jin looked at it and felt that the texture was a bit like a round shoelace rope.

When the mobile phone was passed to Ye Lai, she said: "There are many lanyards made of this kind of rope on the Internet, with a few jade beads on it, and they only cost a few yuan." She searched some on her tablet and showed them to Cheng Jin. "Probably this."

Yang Simi looked at it with Cheng Jin and commented: "Ugly."

Ye Lai said with a smile: "It's cheap, but the sales volume is not bad."

Bu Huan came over to look at it together, "If the murderer is wearing something like this, then I know what kind of person he is, that kind: a young man who is poor, uneducated, and filthy."

"Poor?" You Duo asked, "Zhang Mingxue was thrown into the wild, what was the murderer's vehicle?"

The place where the body was dumped was in the bushes near the road. The murderer should have used transportation to transport the body to the side of the road, and then carried the body into the bushes by human power.

"The body was lying flat when it was discovered, but judging from the condition of the body, the deceased had been lying on his side for a long time after death." The forensic doctor said cautiously, "We speculate that there are two possibilities."

"One is that she was killed in the wild. After she lay on her side on the ground for a period of time, the murderer carried her back to the body dumping point and dumped her body."

"The second possibility is that she was killed somewhere else, and the murderer transported her to the dumping point. She should have used a car. She may have been lying sideways on the back seat of the car for a while. If it was a motorcycle or bicycle , the body must have been lying on the car, and this will be reflected on the body."

"It might be a broken tricycle." Bu Huan said.

The forensic doctor thought about it and agreed: "It's possible."

Bao Junjian objected: "It's unlikely. Because the victim's price is at least [-] times."

So this client can't be too poor, or he can't afford it.

"He is very poor and wants to save money to go whoring, so he hates those girls very much, and then he is motivated to kill. It is because he is poor that he wants to steal Mao Xiaoyan's money." Bu Huan's thoughts were clear.

Now Bao Junjian was convinced, "It seems to make sense."

Cheng Jin looked at Bu Huan, "Do you suspect that the four victims died at the hands of the same murderer?"

"It's possible."

"If this is the case, then the murderer's thinking is very careful."

"Shouldn't this kind of person be poor?" Bu Huan asked.

"What if he likes to gamble or take drugs?" Ye Lai asked.

People with these two problems can lose all their fortunes.

The detectives headed by Bao Junjian nodded repeatedly.

Cheng Jin said: "Let me help you sort out your thoughts. A poor man with a good brain hates prostitutes because he can't afford whoring, and then kills them. Right?"

Everyone nodded, this was what they were discussing just now.

"Put it on Mao Xiaoyan and Li Aihong, this statement is still feasible." After all, one died in a rented house and the other died in a cheap hotel.

"But for the latter two victims, there is no evidence to support the murderer who killed them. Let's rule out the suspected cheap lanyard first—because we haven't seen the real thing, maybe the rope is not strung with cheap plastic beads. , but dzi beads and beeswax?"

Ye Lai said: "Maybe there are two or three murderers?"

"If it was a random victim, that might be the case. But the key point is that the four victims knew each other."

"Yes." Everyone nodded.

"These four victims used to be colleagues. Now Mao Xiaoyan and Li Aihong work in the same place, and Zhang Mingxue and Chen Yao work in another company. Why didn't they continue to work together?" Cheng Jin asked.

These four girls used to work in a club called Fenghuangxuan before, but they changed places two by two.

"Are you asking why they want to change jobs? It is said that they do not earn as much as other stores in their old club, but the share is lower than other stores. Mao Xiaoyan was the first to leave, Chen Yao was the second to leave, and then they left again. Introduce your friends to work with you."
