The Huangpu River flows through this bustling city, with bright lights and flashing neon lights. Various tragedies are staged every day in the city.
On October 28, 2007, a gay woman died on the street. It was midnight. A homeless man saw the woman as beautiful as a flower, and he had evil intentions. He wanted to drag her body to a narrow alley and rape her, but he was beaten by several people.
The well-meaning citizens of Mahjong dispersed. The police on duty from the Criminal Police Detachment of the Pujiang Public Security Bureau rushed to the scene after receiving the report. To their surprise, the deceased was a female police officer from the Pujiang Public Security Bureau, who was their colleague.
On the same night, several passengers on the Huangpu River cruise ship discovered someone swimming in the water. The weather in late October was already very cold. It was very strange for someone to swim. After getting closer, under the light of the cruise ship's search light, they discovered that it turned out to be someone swimming in the water.
A woman with long hair floated on the water behind her. She looked very graceful, like a mermaid. However, what was strange was that the young woman had her eyes closed tightly and her hands and feet were not exposed to the water. Everyone felt
It was strange that the woman floated slowly along the current to the side of the boat. When she got closer, she discovered that it was a female corpse. After preliminary investigation by the public security organs, the identity of the woman was a policewoman from the Pujiang Municipal Public Security Bureau Certificate Application Center.
Two female police officers were murdered in a row, and the case shocked the police community!
The special case team received a request for assistance from the Criminal Police Detachment of the Pujiang Municipal Public Security Bureau and rushed to the local area. In the reception room of the Criminal Police Detachment, the family members of the deceased were crying loudly. The leaders tried their best to comfort them. After a long time, they were sent away.
The captain of the criminal police detachment reported to the special case team that the two deceased persons were both newly assigned to the bureau this year. The policewoman lying dead on the street was named Li Wanting, and the one whose body was dumped in the water was named Sun Qiruo. They were both young and fashionable.
Female, working as a civilian in the Public Security Bureau, responsible for handling ID card loss reports, household registration changes, etc. They are classmates, graduated from the same police academy, and usually live together, renting a three-bedroom house in Yayuan Community.
.The autopsy results showed that the two female police officers were strangled and suffocated to death. Their buttocks were bruised and showed signs of being beaten. One of the two deceased policewomen was thrown into the street and the other was thrown into the river. They were both naked.
Body.
Su Mei said: Could it be that this is another homosexual case?
Professor Liang said: It's definitely not that simple.
The criminal police captain said: Let me show you this. It was tied to Qi Ruo's feet.
The detective captain took out a transparent evidence bag with a pair of leather underwear inside. He turned the bag over and was surprised to find that the underwear also had a simulated latex breast. There was a rectangular battery slot on the side of the leather underwear.
When Bao Zhan got it, Hua Long and Su Mei were worried that he would smell it with his nose. Fortunately, Bao Zhan just looked at it and said shyly: This is the first time I have seen such a thing.
This is the only evidence at present. Professor Liang asked the criminal police captain to introduce it in detail.
The captain of the criminal police said: The stem is 17cm long, with an outer diameter of 4.2cm and an inner diameter of 11.5cm. This is a sex toy for both men and women. The base of the stem is shaped like a vulva and the inside is a gel cavity. It is suitable for people with sexual dysfunction.
, there is a vibrating egg built into the top, which is connected to the power supply. The vibration frequency is adjustable and can be used repeatedly for a long time. It is produced in the south and can be purchased in many adult product stores in the city and online. Such a sex toy is suitable for male masturbation.
, female masturbation, lesbians, and men with sexual dysfunction...
Professor Liang nodded. It seemed that the local police had done a lot of investigation and the work was serious and meticulous.
The criminal police captain said: We initially determined it to be a case of rape and murder, but no signs of sexual assault such as semen were found in the two of them, and... the forensic examination revealed that they were virgins, and their hymens were intact.
Professor Liang said: At present, characterizing rape and murder is the right direction, but we don’t know who raped whom.
Su Mei said: Uncle Liang, do you mean that women rape men?
Professor Liang said: This possibility cannot be ruled out. Do you know Snow White and the Big Bad Wolf in the fairy tale?
Su Mei said: Well, this metaphor is so evil.
Professor Liang smiled and said: The Big Bad Wolf did not rape Snow White, the Big Bad Wolf asked Snow White to rape him!
According to the only clues currently available, the local police were unable to confirm the scene of the first murder, and found nothing suspicious in the investigation of the identity, background and interpersonal relationships of the deceased. On Friday, October 26, two female police officers went off duty and discovered the body at midnight on Sunday.
What exactly happened during the two days of weekend rest? The police checked the phone records of the two deceased people during the two days of the weekend. There were not many phone calls. Among them, the criminal police captain sent a text message to Li Wanting, asking her to go out for coffee. All colleagues in the bureau
Knowing that the relationship between the two was somewhat ambiguous, Li Wanting replied to the text message saying that she was not available and that her attitude towards the criminal police captain had always been cold.
The criminal police captain took the initiative to confess the matter to the special case team. He admitted that he had a good impression of Li Wanting, but they were just colleagues.
Before the arrival of the special case team, Pujiang police conducted an investigation into the residence of the two deceased persons. Li Wanting and Sun Qiruo rented a house together in Yayuan Community, which is located on the Huangpu River. The house is on the fifth floor, opposite the landlord's home. According to
The landlord said that the two people had an argument on Friday night and heard the sound of something breaking. The police found a broken lotion bottle on the floor of the living room, and the computer desk in Sun Qiruo's room showed signs of being moved.
, there were several pairs of stockings of different colors on the sofa in Li Wanting's room. The closet door was open, and in addition to clothes, there were many stockings inside.
The criminal police captain showed the investigation photos to the special case team. In the photos, you can see that the windows of the two female police officers' residences 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: Is there any property missing?
The criminal police captain said: There are no signs of burglary so far.
Su Mei looked at the photos and said: These stockings are very high-end, not low-quality cheap goods.
Bao Zhan said: We should go to their residence to have a look.
Professor Liang nodded and said: Don't just think about what is missing, it is more important to see what is added to the scene.
The criminal police captain drove to the Yayuan community with the special case team. The community is not very high-end and belongs to affordable housing. However, the property management is very standardized. Vehicles need to swipe their cards to enter the community. Those who do not have a door card must register. There are also security patrols at night.
There was a warning seal on the security door of the residence of the two female police officers. The criminal police captain opened the door with the key. Everyone entered the room. There were traces on the wooden floor left by the police when collecting evidence. Bao Zhan suddenly asked: Where did the key come from?
The criminal police captain explained: It was provided by the landlord, and the landlord’s home was right across the door.
There was nothing unusual in the room. The detective captain told the special case team that a luminol fluorescence test had been done, but no blood was found in the room.
Luminol is also known as luminol. To put it simply, the luminol reaction in criminal investigation means that as long as blood is splashed or stained on any object at the crime scene, no matter how it is cleaned up afterwards, even if it has been a long time.
Over a long period of time, as long as the luminol reagent is sprayed on and observed in a dark environment, the areas originally stained with blood will become blue-purple fluorescence due to a fluorescent reaction.
Professor Liang said: The two deceased were strangled to death, so naturally there would be no blood. Have their fingernails been tested?
The criminal police captain said: I have read the forensic identification results several times and found no clues.
Professor Liang said: When the victim is strangled to death, they usually struggle violently and scratch the assailant, and there will be skin tissue of the assailant in their fingernails. Nothing is found in the nails, indicating that the assailant 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 all day. The two computers in the room had been transported back to the criminal police team by the police, and the stockings placed on the sofa were also processed in the bureau.
Technical inspection and meticulous work in the later stage should be able to find clues to solve the case.
Bao Zhan put on gloves and carefully inspected every corner of the room, including the ceiling, toilet sink and other easily overlooked places. He squatted in front of the toilet, carefully picked up a curly hair from the inner wall of the toilet, and put it into the evidence bag.
, then dip the cotton swab into the water in the toilet and put it into the evidence bag.
In the Han**po serial murder case, the murderer was identified from an apple core in the trash can.
In many home invasion shootings in Tokyo, blood was extracted from a dead mosquito at the scene, thus identifying the murderer.
During the investigation and evidence collection, only meticulous work by the police can uncover clues and find a breakthrough point for solving the case.
The computer desk in Li Wanting's room had been moved. Bao Zhan 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 caught Bao Zhan's attention and he stared blankly.
After a while, he shouted loudly: Come here, hurry up.
Everyone came over and couldn't see anything unusual about the half glass of water.
Hualong asked: Xiaobao, what's wrong?
Bao Zhan said: This cup should be empty.
Su Mei said: You mean...it's terrible.
Professor Liang said: Someone, possibly the murderer, came to this room last night!
The criminal police captain thought for a while, patted his forehead, and took out the photo taken by the police in the room yesterday. The photo showed an empty cup on the computer table, and now there was half a cup of water. This showed that after the police investigation was completed,
Someone came quietly to this room and poured half a glass of water. In many cases, the murderer often returns to the scene of the crime to relive the memory to satisfy his perverted heart.
