◎Chapter 21: Female Rapist

The Huangpu River flows through this bustling city, with red lights and neon flashes, and all kinds of tragedies are staged every day in the city of Yuwang.

On October 28, 2007, a ** woman died on the street, it was midnight, a homeless man saw that the woman was as beautiful as a flower, and wanted to drag her body to a narrow alley to rape, but was dispersed by several well-meaning citizens who played mahjong. The police on duty of the criminal police detachment of the Puyuan City Public Security Bureau rushed to the scene after receiving the report, and they were surprised that the deceased was a female policeman from the Puyuan City Public Security Bureau, who was their colleague.

On the same night, several passengers on the Huangpu River cruise ship found that there were people swimming in the water, the weather in late October was already very cold, it was a strange thing for someone to swim, after approaching, under the illumination of the cruise ship's searchlight, everyone found that it was a long-haired woman, the long hair floated on the water behind her, looking very graceful, like a mermaid, but what made people feel strange was that the young woman's eyes were closed, and her hands and feet were not exposed to the water. Everyone thought it was strange that the woman had drifted slowly along the current to the side of the boat, and when they got closer, they found that it was a female corpse. After a preliminary investigation by the public security organs, the woman's identity was a female policewoman from the Puyuan Public Security Bureau's Certification Center.

Two female policemen were killed in a row, and the case shocked the police community!

In the reception room of the criminal police detachment, the family members of the deceased were crying loudly, and the leaders tried their best to comfort them and made a fuss for a long time before sending them away.

The captain of the criminal police detachment reported to the special case team that the two deceased were both newly assigned to the bureau this year, the policewoman who was lying on the street was named Li Wanting, and the body that was thrown into the water was called Sun Qiruo, both of whom were young and fashionable women, who worked as civilians in the public security bureau, and were responsible for handling the loss of ID cards and household registration changes. They are classmates, graduated from the same police academy, and usually live together, sharing a three-bedroom house in the Graceland community. The autopsy revealed that the two policewomen had been strangled to death, with bruises on their buttocks and signs of beating. The two deceased, one was thrown into the street and the other was thrown into the river, both with their bodies **.

Su Mei said: "Could it be that this is another case of homosexuality? ”

Professor Leung said: "It's definitely not that simple. ”

The captain of the criminal police said, "I will show you this, which was tied to the feet of the Den. ”

The captain of the criminal police took out a transparent evidence bag with a pair of leather panties in it, flipped the bag over, and found that the panties also had a simulated latex **, and there was a rectangular battery slot on the side of the leather panties. Bao Chop took it in his hand, and Hualong and Su Mei were worried that he would smell it with his nose, but fortunately, Bao Chop just looked at it, and he said a little shyly: "It's the first time I've seen this kind of thing." ”

This is the only evidence at present, and Professor Liang asked the captain of the criminal police to give a detailed introduction.

The captain of the criminal police said: "The stem is 17cm long, the outer diameter is 4.2cm thickest, and the inner diameter is 11.5cm, which is a unisex sex toy, the bottom of the stem is a vulva shape, the inside is a colloidal cavity, suitable for people with sexual dysfunction, and a vibrating vibrating egg is built at the top, which is connected to the power supply, and the vibration frequency is adjustable, which can be used repeatedly for a long time." It is produced in the south and can be purchased in many Chéng Rén stores in the city and online. Such a sex toy for men masturbating, women masturbating, lesbians, and men with sexual dysfunction ......"

Professor Liang nodded: "It seems that the local police have done a lot of investigations, and the work is serious and meticulous. ”

"We initially thought it was a rape and murder case, but there were no signs of sexual assault such as semen in the two of them, and there were ...... If the forensic examination is a virgin, the hymen is intact. ”

"At present, characterizing rape and homicide is the right direction, but we don't know who raped whom," Professor Leung said. ”

Su Mei said: "Uncle Liang, do you mean - a woman rapes a man?" ”

Professor Liang said: "I don't rule out this possibility, the fairy tale Snow White and the big bad wolf, do you know? ”

Su Mei said, "Well, this metaphor is so evil. ”

Professor Liang smiled and said, "The big bad wolf didn't rape Snow White, the big bad wolf asked Snow White to rape him!" ”

According to the only clues so far, the local police could not confirm the scene of the first murder, and the identity background and interpersonal relationship of the deceased did not find anything suspicious, and on Friday, October 26, two female police officers were off duty and found the body at midnight on Sunday.

What happened during the two days off on the weekend, the police checked the phone records of the two deceased on the weekend, there were not many phone calls, among them, the captain of the criminal police sent a text message to Li Wanting, asking her to come out for coffee, colleagues in the bureau knew that the relationship between the two was a bit ambiguous, Li Wanting replied to the text message that she was not available, and her attitude towards the captain of the criminal police has been cold.

The captain of the criminal police took the initiative to explain the matter to the special case team, and he admitted that he had a good impression of Li Wanting, but it was only a colleague.

Before the special case team arrived, the Pujiang police conducted an investigation of the residences of the two deceased. Li Wanting and Sun Qiruo share a house in the Graceland community, located on the Huangpu River, on the fifth floor, opposite the landlord's home. According to the landlord, the two had an argument on Friday night and heard the sound of something breaking. The police found a broken bottle of body lotion on the floor of the living room of the room, the computer desk in Sun Qiruo's room had traces of moving, there were several pairs of stockings of different colors on the sofa in Li Wanting's room, and the door of the wardrobe was open, and there were many stockings in addition to clothes.

The captain of the criminal police showed the investigation photos to the special case team, and the photos show that the windows of the two female policemen are bright and clean, fashionable and elegant, and some cute accessories show the girls' interest in life.

Professor Liang picked up a photo and asked, "Have you lost any belongings?" ”

The captain of the criminal police said: "There are no signs of burglary at this time. ”

Su Mei looked at the photo and said, "These stockings are very high-end, not inferior bargains. ”

"We should go to their quarters again," Bao said. ”

Professor Liang nodded and said, "You can't just think about what you've lost, it's more important to see what you've added to the scene." ”

The captain of the criminal police drove to the Graceland community with the special case team, the community is not very high-end, it is an affordable housing, however, the property management is very standardized, the vehicle needs to swipe the card to enter the community, and those who do not have a door card must be registered, and there are security patrols at night.

The security door of the residence of the two female policemen was affixed with a security seal, and the captain of the criminal police opened the door with a key, and everyone entered the room, and there were traces left by the police when they collected evidence on the wooden floor. Bao Shu suddenly asked, "Where did the key come from?" ”

The captain of the criminal police explained: "The landlord provides the opposite door, which is the landlord's home. ”

There was nothing unusual in the room, and the captain of the criminal police told the special case team that a luminol fluorescence test had been done, but no blood stains were found in the room.

Luminol is also known as luminous ammonia. The luminol reaction in forensics, simply put, is that as long as there is blood splashed or stained on any object at the scene of the murder, no matter how it is removed afterwards, even if it is after a long period of time, as long as the luminol reagent is sprayed and observed in a dark environment, the original bloodstained place will be blue-purple due to fluorescence reaction.

Professor Liang said: "The two deceased were strangled to death, so naturally there will be no blood. Have their nails been examined? ”

The captain of the criminal police said: "I have read the forensic examination results several times, but I have not found any clues. ”

to devour

"When the victim is strangled to death, he or she usually struggles violently and scratches the murderer, and the murderer's dandruff tissue is present in the fingernails. Nothing was found in the nails, indicating that the killers probably tied their hands behind their backs......"

The captain of the criminal police said that yesterday, the Pujiang police found no valuable clues in the preliminary evidence collection, they were busy for a whole day, the two computers in the room have been transported back to the criminal police team by the police, and the stockings placed on the sofa are also being technically tested in the bureau, and the clues to solve the case should be found through the meticulous work in the later stage.

Wearing gloves, Bao carefully inspected every corner of the room, including the ceiling and the toilet sink. He squatted in front of the toilet, carefully pinched a curly hair from the inner wall of the toilet, put it in the evidence bag, and then dipped a cotton swab into the water in the toilet bowl and put it in the evidence bag as well.

In the Han ** Po serial murder case, the murderer's identification stemmed from an apple core in the trash can.

In a number of burglary shootings in Tokyo, blood was extracted from a dead mosquito at the scene, which led to the identification of the murderer.

In the investigation and evidence collection, the police can only find clues and clues through meticulous work, so as to find a breakthrough point for the cracking of the case.

The computer desk in Lai's room had been moved. Bao Chop carefully observed the back of the computer desk with a magnifying glass, and found nothing suspicious, however, the half glass of water on the table attracted Bao Chop's attention, he looked blankly, and after a while, he shouted loudly: "Come here, hurry up." ”

Everyone walked over and couldn't see anything unusual about this half glass of water.

Drawing Dragon asked, "Xiaobao, what's wrong?" ”

Bao said: "This cup should be empty. ”

Su Mei said, "What do you mean...... It's horrible. ”

Professor Liang said: "Someone, who may also be a murderer, came to this room last night! ”

The captain of the criminal police thought for a while, patted his head, and took out the photo taken by the police in the room yesterday, which showed an empty cup on the computer desk, and now there is more than half a glass of water, which means that after the police investigation, someone quietly came to this room and poured half a glass of water. In many cases, the murderer often returns to the scene of the crime and relives his memories to satisfy his perverted heart.
