criminal profiling

In recent days, following the case so closely, many police officers didn't go back to sleep, and went straight to the office.Zhuang Sheng lived in the dormitory provided by his unit, not far from here, just a few minutes' walk away. He came early, and when he arrived at the criminal investigation office, he saw a policeman sleeping on a table. Not long after, the captain of the criminal investigation team came.

After chatting briefly for a while, Kong Dongning called a female police officer and asked Zhuang Sheng to go through the relevant procedures with her.After completing the formalities, it was almost ten o'clock. When Zhuang Sheng returned to the office, he saw that almost everyone from the Criminal Investigation Brigade was there.

Kong Dongning pulled Zhuang Sheng over and briefly introduced them to the team.

"This is Dr. Zhuang Sheng, an expert in criminal behavior analysis. He has been an intern at the FBI for two years. He is a technical talent specially hired by the bureau. He will work with everyone in the future."

When they heard the words "criminal behavior analysis", the detectives below all had strange expressions on their faces. There seemed to be something more in the eyes staring at Zhuang Sheng, and some even exchanged a knowing look with each other.

From their eyes, Zhuang Sheng saw doubt and a little resistance.

Is it against him, or against the role he will fill in the force?

Zhuang Sheng didn't know, and didn't care.

Vice-team Shi Ke sat on his chair with his legs crossed, with an expression on his face that he hadn't slept enough. He shook his head when he heard Kong Dongning calling his name, and sat upright.

"Shi Ke, Xiao Zhuang has just joined the team and is not familiar with this place, so you take him for a while first." Kong Dongning said, turning his head to look at Zhuang Sheng, "Xiao Zhuang, there happened to be a murder case recently, so I won't let you know. Let’s wait until the case is solved.”

"Captain, can I participate in this case?" Zhuang Sheng didn't care about what was going on or not. Knowing that there was a murder case, it was impossible for him to stay out of it and slowly do things like getting familiar with the environment.

"Of course." Kong Dongning nodded, and asked Shi Ke to show Zhuang Sheng all the materials of the two cases.

Shi Ke brought over all relevant materials, including records and photos of the on-site inspection, autopsy report, social relationship investigation of the first victim, etc.

Shi Ke put a thick stack of documents in front of Zhuang Sheng, turned to look at Kong Dongning and said, "Captain Kong, I want to go to the scene to check again. The house of the first deceased was burnt beyond recognition, and not much was left. Valuable clues. The autopsy report of the No.2 deceased just came out, and I want to go back to the scene and check again to see if there are any missing clues."

Kong Dongning nodded, pointed at Zhuang Sheng and said, "Yes, you can take Xiao Zhuang with you. He has seen no fewer crime scenes than you. Letting him go with you may not necessarily provide new ideas."

Glancing at Zhuang Sheng who was flipping through the materials quickly, Shi Ke frowned unconsciously, "Captain Kong, he just came today, let him understand the situation in the bureau first, and read all the previous materials. Take him to work."

Before Kong Dongning answered, Zhuang Sheng looked up at Shi Ke and said, "No, I can finish it in a few minutes, or I can take it to the car to watch."

Shi Ke was silent for a while, looked at the information he seemed to put on the other side after reading it, and asked with some disbelief: "You finished reading those?"

Zhuang Sheng nodded, his expression was calm and indifferent, and he didn't feel that he had done anything special, "Yes, I saw that you have identified several suspects for the No.1 deceased through investigation. You want to treat these two murders as one Have two different cases come to investigate?" When he was talking, his eyes were still fixed on the documents in his hand, like a scanner turning pages in a few seconds, and Shi Ke stared at him for a moment without reacting.

"At present, there is no definite evidence to prove that the two cases were committed by the same person, so we can only investigate it as two murder cases for the time being." Kong Dongning answered Zhuang Sheng's question, but he did not show Zhuang Sheng's reading speed. Looking too surprised, he just nodded, feeling very satisfied. "That's it. After a while, Shi Ke, you will take Xiaozhuang to the scene."

Shi Ke shrugged his shoulders and said nothing more.

After a while, Shi Ke drove Zhuang Sheng to the scene of the second murder.

This is a residential area, the victim lives on the second floor, there are anti-theft doors downstairs, and the users on the first floor are also equipped with anti-theft windows.

The second homicide happened the day before yesterday. The technicians had completed the investigation and evidence collection at the scene, but since the case was not solved, everything inside remained as it was.

"The deceased, Jiang Wei, died at 28:[-] p.m. on the [-]th. The body was found around [-]:[-] a.m. the next day. The person who made the report was a resident of the opposite building. He accidentally saw what was going on in the kitchen through the window, so he called the police. "

"When the police came, the door was locked and the doors and windows were not damaged, which means that the deceased opened the door and let the murderer in."

"The deceased can open the door by himself. Generally speaking, it is either a courier or takeaway staff, or someone he knows. No defensive wounds were found on the body, so the deceased did not resist."

Shi Ke tried to restore the scene at the time of the crime. He walked slowly from the door to the kitchen, and the chairs by the dining table were still there. Breaking leads to death—why choose such a strange way of killing? Does it have any special meaning to the murderer?" Shi Ke has been unable to figure out this question. In general homicides, the tools used to commit crimes are relatively common knives, ropes or steel pipes. Humans, using food as a killing tool, Shi Ke met for the first time.

"Also, after the autopsy, the doctor said that there was dehydration and severe malnutrition. This is a condition that can only appear after being starved for a few days-the murderer kidnapped the deceased and locked him in a certain place. He was not given food and water for several days, and then When he is about to starve to death, force him to eat a large amount of food, burst his stomach and die. What's the point of doing this?"

The more Shi Ke talked, the more puzzled he became, and felt that this case was simply weird.Suddenly remembered that there was another person in the room. He talked so much to himself, but Zhuang Sheng remained silent. Shi Ke almost forgot his existence.Shi Ke turned to look for it and found that Zhuang Sheng was checking the refrigerator.

There was some beer in the fridge, and some other food.

"It looks like Jiang Wei is an alcoholic." Shi Ke looked at the rows of beer and couldn't help sighing.

"Has he been drinking or eating irregularly for a long time?" Zhuang Sheng asked, his eyes still resting on those foods.

"What did you think of?" Shi Ke asked casually while pulling out the phone.

Zhuang Sheng shook his head, but did not answer.

Shi Ke shrugged, and after the call was connected, he said to the person on the other end: "Xu Jie, can you find out about Jiang Wei's consumption?"

"Captain Ke, if he spends in cash, I won't be able to find out."

"Well, I know, you can try it."

"I need to check the two corpses." Zhuang Sheng stood up, looked at Shi Ke and said.

Scott paused, staring at his eyes and asked again: "What did you think of?"

Zhuang Sheng still shook his head, but this time he replied, "I'm not sure yet."

Seeing the back of Zhuang Sheng turning away, Shi Ke felt an inexplicably familiar feeling, that kind of feeling that made people a little crazy, and a little bit of hatred.

"I hate people who say half and leave half."

Because when you can't figure it out, it will make people feel that your IQ is not enough.

Shi Ke muttered something in a low voice, followed Zhuang Sheng and left.

Morgue.

The dissected corpse was covered by a white cloth. Zhuang Sheng lifted the white cloth, first observed the head of the corpse, and then lifted the limbs of the deceased to examine carefully.

Except for the marks of being bound on the hands and feet, there are no other injuries.In other words, the murderer abused the deceased by means of starvation. He could have directly starved the person to death, but he chose not to do so.Instead, before Jiang Wei was about to starve to death, he was stuffed with food to support him to death.

"Before Jiang Wei died, was there any drunkenness?" Zhuang Sheng asked the doctor in charge of the autopsy. The doctor flipped through the autopsy report and said, "There is indeed alcohol in the blood, but it's hard to guess the degree of drunkenness."

"Finding out that the deceased was an alcoholic, will this help the analysis of the case?" Shi Ke asked Zhuang Sheng. An hour ago, Xu Jie sent the information he found to Shi Ke's mobile phone, all of which were Jiang Wei's online credit card. A record of ordering beer.

"The murderer knows Jiang Wei very well, so it is very likely that he entered the house with the help of wine, then got him drunk and tied him up. Jiang Wei has been drinking for a long time, has no regular job, and lacks friends, so he was imprisoned in his own home for several days. Nobody found out."

"Wait, how do you know that he is locked up in your own house? Could it be that the murderer stayed at Jiang Wei's house all those days?" Shi Ke interrupted Zhuang Sheng. The look of "I see what flowers you can name".

Zhuang Sheng didn't care about his contemptuous attitude at all, he spoke at a slightly faster speed than usual, and continued to speak without any ups and downs in his tone.

"If you kidnap someone first, starve for a few days and then take him back to Jiang Wei's home to kill him, the risk is too high and there is no need for it. The murderer knows that Jiang Wei's place will not be visited by people except for food deliveries, so He imprisoned Jiang Wei in his home, and in order to know his situation at any time—or to see his torture with his own eyes, he stayed in the house himself.

"The neighbor who reported the crime said that he only saw the situation in the kitchen because the curtains of the opposite building were opened. The curtains had been drawn all the time. Apparently the murderer had been there until Jiang Wei died. He opened the curtains before leaving. The purpose is to let people discover Jiang Wei's body."

The more Shi Ke listened, the more surprised he became, "Why?"

Zhuang Sheng was silent for a moment, and the appearance of another corpse appeared in his mind, which was completely charred—but she was not burned to death, but died of suffocation by inhaling a large amount of thick smoke.

"Because he killed these people, no matter what the purpose was, he didn't want to hide the corpses, but wanted to make them public and let many people know."

"These people? You mean that the two murders were committed by the same person? What evidence do you have?" Shi Ke frowned and questioned Zhuang Sheng dissatisfied.For the first murder case, they investigated for a week, and basically identified the suspect. Zhuang Sheng only investigated with him for a long time, and said that the two cases were committed by the same person.

Could it be that he spent two years in the FBI, so as long as he saw more than two dead people, he thought it was a serial murder case?

Zhuang Sheng looked at him silently, not getting angry because of his questioning, but staring into his eyes, and said something slowly.

"Wait until the third victim appears, and you will see the evidence you want."
