When her colleague checked it just now, she told him that the door lock was not damaged at all. She was wondering if it could be opened with a key?
However, after comparing the keyhole, they found that the key that opened the door was not the original key, but a very hard substance. However, they did not know what it was exactly. They could only find out after detailed testing. Discover.
"Do you think the suspect was engaged in this industry before? For example, a locksmith?"
Mu Wen boldly guessed, but as soon as the words came out, Xu Jinran looked at Mu Wen warily.
"Actually, it's very possible. Generally speaking, if you can skillfully open this kind of door lock, you must have received professional training. If this is the case, then they should have registered it with the public security department."
"But there is another possibility. Some people are born with a talent for stealing, and they can easily open the door lock. Naturally, these people have not registered with the public security bureau.
"Yes, I know that too, but we'd better check it out. In this case, we may be able to narrow down the scope of our investigation."
While the two were discussing the case outside, Luo Qianran walked out with a clip.
"Has Professor Luo discovered anything?"
Xu Jinran asked excitedly after seeing Luo Qianran coming out.
"Based on the environment at the scene, I have made a bold inference. The suspect should be around 40 years old, but he should not be over 40 years old. Moreover, the suspect should have lived alone or with a child for a long time. .
In addition, the suspect has a strong obsessive-compulsive disorder. We can detect this from his crime-committing methods at the scene, and I can infer that the suspect's height should be around 1.78 to 1.80 meters. He is very tall. He is a man, but he is not very fat. Moreover, he is relatively withdrawn and not good at interacting with others. "
Luo Qianran only stayed inside for a short ten minutes and calculated a rough physical feature of the suspect. Xu Jinran felt like he was dreaming after hearing this.
"Is this, is this the legendary psychological profiling?"
"Yes, but this kind of psychological profiling is rarely used in our country, because most people believe in the evidence, but in the case in the United States, they believe in it very much. First of all, They will determine the range of suspects based on psychological profiling, and then identify a specific suspect based on specific evidence."
"So that's the case. Why do you infer that he lives alone, and most likely has a child?"
"In the victim's room, did you notice that there was a beautiful teddy bear placed by the victim's window?"
Speaking of this, Xu Jinran hurriedly looked back into the room. She really hadn't noticed the little bear placed there just now.
"Yes, there is indeed a little bear, but does it have anything to do with this case?"
"It can be seen that the position of the little bear has been moved, and according to normal calculations, the little bear will definitely be stained with blood, but the little bear was picked up and placed in a very high position, as if he did not want to Just like letting him be contaminated by the blood of the victim."
After hearing Luo Qianran's description, Xu Jinran recalled it carefully, and it seemed that it was indeed like this.
The current bear is placed at a high position at the head of the bed, and even a child may not be able to reach it when he stands on it. It is obvious that the child did not put it up by himself.
"But does this have anything to do with whether he lives alone or has children?"
"Of course, if there is a child around him, and he will love the child very much, so he will pay special attention to everything the child uses, especially after arriving at the scene of the crime, he will still do the same, So I concluded that there should be a child beside him."
"But I just heard you say that he is single, can't he have a wife?"
After hearing this, Luo Qianran just smiled at the two of them, and then shook his head gently.
"No, he will never have a wife."
"Why? Why are you so sure?"
Xu Jinran and Mu Wen asked almost in unison this time.
After finishing speaking, the two people looked at each other. Unexpectedly, they were so united this time, which made Mu Wen a little uncomfortable.
"This is what I inferred based on the circumstances at the scene, but I can't guarantee 100% that he is single."
"What's the environment like at the scene?"
"Look, the suspect originally wanted to clean this room when he had time, and you also saw that the rag he took should have been found in the kitchen, rather than just taking one randomly. This proves that he usually He must be very careful in what he does. Let me ask you, if there is a wife at home, which man would be so careful?"
Mu Wen thought for a while, and it seemed that this was indeed the case, but it was not absolute. Maybe this man was naturally careful and liked to take care of others?
"But at the scene of the last crime, I saw her tidying up the room very carefully. Even when he was tearing human skin, I could see that his hands were very coincidental, so I concluded that he should He was alone with his children, without a woman to take care of them.
Moreover, he is both a father and a mother, and it takes time to develop such a character. This is just my personal idea, but we don't know yet whether this is the case. "
"Professor Luo, can you really infer so many things from just one psychological profile of yours?"
"Based on the situation at the scene, as well as his modus operandi and tools, I can indeed infer such a conclusion, but I can't guarantee it to you whether it is accurate, but at least it will be close to 80%, so you You must pay attention to these points when investigating.”
"Okay, since no clues can be found here, let's go back and see if there is anything identified in the physical evidence, and then seize the time to hold a case discussion and let's analyze the next step of the investigation."
After the three people finished speaking, they left the scene of the crime. They quickly rushed to the task force. At this time, parts of the appraisal reports had begun to be delivered to the desk of the task force's office.
Xu Jinran took out these reports, looked at them carefully, and then put them in Mu Wen's hands.
