crime profiler in the dark

The Baihu Branch Office is located on Xikui Street, Baihu Avenue, TMX City. A five-story horseshoe-shaped building is located here. Although the building is not high, it occupies a very large area.The first floor is the window department of the patrol police and the traffic police, the second floor is the detention center and the file management department, the third and fourth floors are the office area, there are criminal investigation department, traffic control department, support department, anti-narcotics department, public relations department, special operations department, The Internet Supervision Department and the Administration Department, etc., the fifth floor is the conference room and the independent office of the high-level police station.There are sub-offices under each department, and each sub-office has three to five teams, and each team has four to six police officers. It can be said that the police force is abundant.

Bai Haolin returned to the police station and reported to Superintendent Cheng, then went to the Criminal Investigation Division [-] to find Sergeant Chen to understand the case.

Sergeant Chen handed the prepared materials to Bai Haolin:

"On the second day after the incident, we went to Jixiang Village to understand the situation. At first we started from the perspective of vendetta-the girl's parents remarried. According to the villagers, her mother and her ex-husband had a lot of trouble when they divorced. It’s very pleasant, but this person’s whereabouts are unknown now, and on the day of the incident, two villagers claimed to have seen a suspicious-looking man wandering nearby.”

Li Mei's death was tragic, and it is reasonable to investigate from the perspective of vendetta, but now there is a new victim in Shenzhen, which disrupts Chief Chen's original investigation angle.

After Sergeant Chen briefly introduced Li Mei's case, he passed another document to Bai Haolin. Compared with Li Mei's case, this document is much thinner:

"This is the case of Shenzhen. I asked two police officers to go to the scene to understand the situation. I will contact you later when they come back."

"Okay, I'll go back to the office to familiarize myself with the information."

The psychological counseling office is located in the support department on the fourth floor. In order to ensure the privacy of the police officers conducting the psychological assessment, Bai Haolin has an independent office, which also gives him enough private space.

Bai Haolin first read the case of Li Mei in Kangzhen:

The scene of the crime - Li Dahai only returns to Jixiang Village during the fishing season, and works outside the rest of the time. Li Mei usually lives in school and rarely goes home.

Li Dahai's family was in financial difficulties and had no house, only a simple houseboat with a living room and a bedroom. When Li Dahai walked into the inner bedroom, he found that his daughter had been killed! !

Li Mei was wearing a red dress when she was killed. Her hands and feet were tightly bound by a finger-thick iron chain, and an anchor was tied between her feet. Because of the long iron chain, the anchor fell to the ground. , her hands were tied to the beam, her feet were a few centimeters off the ground, and there was an overturned bench next to her!

Li Dahai cried and called the police. The police officer surnamed Liu from the Public Security Department arrived at the scene of the crime quickly. After taking pictures of the scene, the two worked together to put Li Mei down. They found that Li Mei had a circle of strangle marks on her neck.

Forensic situation - the police officers of the Support Department of the Baihu Police Station collected all the objects at the scene of the crime, and took photos before collecting them, so they can clearly see the situation at that time.

Li Mei's clothes and sundries were scattered in the room. Her textbooks, homework books, calculator, schoolbag, and change were scattered on the bed in the bedroom. There were two packets of instant noodles on the table, one of which had already been eaten.

On the bed, forensic officers found drip marks from candles, as did the same wax marks on the bathing suit.The anchor weighs twenty catties. According to Li Dahai's identification, it is his own property, but it has not been used for a long time, and it is full of rust.

According to the inspection by the support department, only Li Mei's own fingerprints were found on the chains, anchors and other objects.

Autopsy results - According to the forensic autopsy, Li Mei died between [-]:[-] am and [-]:[-] am. The cause of death was suffocation. There was a pinhole, from which the forensic doctor extracted a two-inch long needle, which was inserted by the murderer after Li Mei's death. The deceased had had consensual sex before his death, and no sperm spot was found.

The current conclusion is: Li Mei lured the wolf into the house, took the murderer home, had sex with the murderer, was strangled to death by the murderer, and then the murderer arranged the scene in a strange way.

As for the case of Shenzhen, which was discovered two days ago, there are only preliminary autopsy results and case information.The deceased was Wang Hai, who had just turned 13 years old. The cause of death was suffocation. Like Li Mei, he had strangle marks on his neck, hands and feet, and a two-inch long needle was nailed into his forehead. The time of death was also at one o'clock in the morning. Between three o'clock, the iron chains binding his hands and feet and the anchor under his feet were covered only with his own skin cells and fingerprints. The red dress he wore was not his own. Unlike Li Mei, he had no sex with anyone during his lifetime. had sex, and had tears stained his face.

According to Wang Hai's parents, Wang Hai has always been obedient, and his family is very relieved of him. On the day of the incident, he left school alone. The teacher asked, only then did he know that school was over long ago, Wang Hai's family was in a hurry and searched everywhere to no avail. Early the next morning, morning joggers found Wang Hai's body in a small park in the town.

There is no doubt that the murderer in the two cases is the same person. Judging from the red dresses and red clothes worn by the two deceased, this person has fetishism, sexual violence and sadistic tendencies.

Just as Bai Haolin finished reading the materials, the phone on the desk rang:

"Hello, Psychological Counseling Office."

"Xiaobai, it's me," the voice of Sergeant Chen from the Second Criminal Investigation Division came through the phone, "The police officers are back, let's make a briefing."

Bai Haolin agreed, took the materials and returned to the Criminal Investigation Division [-].

Sergeant Chen has three other police officers, all of whom are all male. After a brief self-introduction, everyone began to tell everyone about their findings. The first person to speak was Lao Sun, who went to the town to investigate the scene. Lao Sun was over 50 years old. , He will be able to retire honorably in two years. He is an old policeman with great experience in criminal investigation. He took out his notebook and held it as far as his arm could reach. He squinted his eyes from time to time to see clearly. The above words:

"We met Wang Hai's family and teachers. According to them, Wang Hai is very honest, he doesn't make noise at school, and he won't do anything cheating. It's just that he is introverted and doesn't have many friends. Go home and never play with classmates. They have no idea who the murderer is."

"Wang Hai is one kilometer from school to home. The child usually walks for half an hour to go home. We asked the surrounding merchants along the route Wang Hai went home." He is many years old, just graduated from the police academy, and is still in the learning stage. "On the day of the incident, Wang Hai bought a popsicle in a small shop 20 meters away from the school, and then disappeared." The prepared map was distributed to everyone. On the map, the route Wang Hai often took home and the location of the shop he last appeared were carefully marked with red pens.

"That park is not big, and there are no people there after ten o'clock in the evening, so there are no witnesses. That's all there is now." Lao Sun closed the notebook and concluded.

"About the first case," another police officer named Fang Xiang, in his 30s, "before the media had suspected Li Mei's teacher, and then bombarded her school and teachers with various public opinions. Five days ago, her teacher Unable to bear the pressure, he committed suicide, because there was a second case of the same red dress, the suspicion of the teacher was completely ruled out, and the teacher's family will file a civil lawsuit against the irresponsible media."

"You're talking about Xiao Ke's gossip, right? I've watched that episode, and I think what the psychiatrist said is quite reasonable. The deceased did have sex before he was alive, and wax marks were found on the deceased. Isn't that true? What is SM?" Xiao Li said, "I didn't expect it to be a serial case."

"Have you ever investigated that teacher?" Bai Haolin, who had been listening carefully to their speech, asked.

"After investigation, he had an alibi, so he was released. I didn't expect the media to insist on him, trying to prove that he was the murderer. I didn't expect him to kill someone." Sergeant Chen felt very sorry.

"What's going on in the media now?" Fang Xiang asked.

"I heard from the public relations department that these two cases are of great importance and are going to be reported to the media. Of course, some details will not be released to the public, so we can use this to screen suspects." Sergeant Chen asked Bai Haolin after speaking, " Doctor Bai, have you found anything?"

"Based on the current information, the murderer is between 25 and 40 years old, lives alone, has fetishes, is not confident, has a high probability of ability problems, is unemployed or engages in relatively free occupations, such as salesmen, freelancers Those who wait."

"Didn't No. 1 deceased have sex? How could the murderer have sexual problems?" Xiao Li was puzzled.

"General sexual abusers would torture the deceased before they were alive, but this murderer strangled the two deceased with his bare hands, and then arranged the scene. There were not many traces of abuse on the corpse. overkill, such as multiple stab wounds. I judged that he had sexual problems because of the needles on the foreheads of the two deceased. The autopsy report stated that the needles were completely nailed into the foreheads of the deceased. The needles were The insinuation of the murderer's psychological state, just like some murderers will stab the victim's body with a knife to represent psychological violence."
