The wife of the power minister's family

Xiao Yi was stunned for a moment, then Xu Jing continued: "When I investigated Zheng Shouyan's case earlier, I told you that this kind of serial murderer refers to a murderer who commits multiple crimes in succession and kills multiple victims. They all have certain rules and hobbies, and these rules and hobbies will not change easily, especially the frequency of killing and the way they kill.

If the circumstances of their crimes have changed, it is most likely related to their personal changes in life or psychological changes. For example, Zheng Shouyan suddenly accelerated his murder rate because he discovered that he was suffering from diabetes mellitus. Knowing that he was not going to die soon, he was completely unable to suppress the desire to kill in his heart. "

Although Xu Jing is a forensic doctor, she often cooperates with people from the public security organs to investigate cases. At that time, one of the departments she often cooperated with had a very outstanding psychological criminal expert. Xu Jing also learned some knowledge about psychological crimes through the influence of her ears and eyes. .

Xiao Yi quickly understood what she meant, "This smiling killer came out after dormant for a year. Not only has the time between each crime been shortened, but his killing methods have also obviously changed."

"Yes, and this change is not that big. If the cases he committed in the first two years can be classified as rape and murder, the cases he committed later are simply torture and murder."

Xiao Yi couldn't help but ask: "What is the difference between these two cases?"

In his opinion, these are both murder cases, but the latter's method is more cruel.

Xu Jing thought for a while and said: "The perpetrator of a rape and murder case usually commits the crime for sex... Well, to put it simply, it means that he has a desire for a certain woman and therefore commits the crime. However, most of them The perpetrators of torture and murder cases are not concerned about the woman herself, but...the abuse of the perpetrator himself and having a relationship with the victim are generally just incidental things for this type of perpetrator."

Some serial murderers are even impotent or disdain to have sex with their victims, because in their minds, the torture of their victims is far more attractive than the victims themselves.

Even though this was not the first time Xiao Yi discussed a case with Xu Jing, and it was not like he had never solved a case of a woman being raped before, seeing her speak so frankly about the relationship between a man and a woman, he still felt a little nauseous in his heart. The expression was so subtle that he couldn't help but clear his throat and said: "So you think that some major changes may have happened to the murderer, so he made these changes? The time when he had major changes was probably at the time when he suddenly disappeared. year."

Xu Jing still felt that something was not right.

But now, the most likely answer is indeed this.

She mused: "The murderer suddenly disappeared for a year, which is also very intriguing. Judging from the fact that he continued to commit crimes later, his desire to commit crimes has not subsided. In the fourth year of Tianxi, why did he suddenly stop? I am inclined to I think he was unable to commit the crime because of certain things, and it may have been that incident that contributed to a major change in his subsequent crime style."

There are many reasons why the murderer suddenly did not show up - he was sick, and he left Xijing for something. He actually killed someone but the government did not find out. It is even possible that he committed some crime and was imprisoned, so he was unable to commit the crime. …

Based on the information she currently has, it is impossible to draw an accurate inference.

Xiao Yi looked at her quietly. Seeing that she was lost in thought, he couldn't help but whisper: "If you care, I will have people bring over all the files related to this case. You will have to wait until get out of class is over. Before that, you can Let’s look at the relevant files first.”

Xu Jing couldn't help but her eyes lit up.

She was originally worried about what to do while she was waiting for her long smile, but now she didn't have to worry about it.

Seeing her like this, Xiao Yi couldn't help but smile lowly, and found another attendant and asked him to bring over all the files related to this case.

After a while, the two attendants who had just left came over with two piles of files piled on a tray and placed them on the table.

For such a big case, there must be a lot of relevant information. Xu Jing picked out the corpses of the five victims and looked at them quietly.Xiao Yi glanced at her, sent someone over with a plate of snacks, then picked up a file, opened it and read it carefully.

For a while, the small pavilion was so quiet that I could only hear the sound of the wind blowing the leaves, the sound of servants walking in the distance, and the occasional sound of koi carp jumping out of the water in the pond nearby. The weather in early autumn was dry but comfortable. It's refreshing, and occasionally the wind blows over the body, just like the mother's gentle hands gently caressing the child's body through the golden sunshine.

At a certain moment, Xu Jing raised her head unconsciously and was slightly startled when she saw the man sitting opposite her, leaning back in a chair with rare relaxation, holding a file in one hand and gently stroking the tea cup on the table with the other. .

I don't know since when, she was able to ignore the impact of the original owner's memory on her, and look at this place and the man in front of her with a calm attitude.

As if feeling Xu Jing's gaze, Xiao Yi suddenly raised his head, looked at her quietly with a pair of deep black eyes, and said, "What's wrong?"

Xu Jing suppressed the incomprehensible thoughts in her heart, shook her head and said: "I have read the corpses of these victims. Indeed, as Xiao Shilang said, the tragic situation of the last three victims when they died is not the same as the first two victims. What can be compared with others is that the injuries on their bodies also have certain patterns. For example, the burns, stick wounds and bare-hand wounds on their bodies are all distributed in similar locations. Their fingernails and toenails are all peeled off, and it is judged that the murderer used pliers. A type of tool was used to peel off the skin, and the skin on the chests of the three victims was torn off in pieces."

The most cruel thing is that those injuries were clearly injuries sustained during life, which means that the deceased was conscious when he was tortured.

After a pause, she said: "I also thought about the possibility before that the next three deceased people might be like Wang Wuniang, someone else imitating the Smiling Killer to commit the crime."

Xiao Yi looked at her and asked, "Then do you think it was a copycat crime?"

"No," Xu Jing shook her head, "I compared the suturing techniques of the red threads on the mouths of the five victims. Their techniques and the appearance of the sutures were similar. The murderer was obviously proficient in needlework, and the needlework was very fine and neat. It is difficult to imitate. from.

Men who are proficient in needlework are rare. I think this can be used as a breakthrough point in future investigations. "

This further highlights how poorly the imitation of Wang Wuniang’s murderer was done.

The stitches at the corners of Wang Wuniang's mouth were messy and rough, and it didn't look like the Smile Killer technique at first glance.

However, other than that, she could see no other clues in the corpse box for the time being.

She couldn't help but look at the other files. Just when she was about to pick up the other files, Xiao Huaian's excited voice came over, "Auntie, daddy! I'm out of class. Master Wen said that my handwriting has improved again today!" "

Xu Jing was stunned. An hour passed like this. Wasn't it too fast?
She could only suppress her thoughts for the time being, stood up and hugged the little one who rushed towards her.

Xiao Yi couldn't tell what she was thinking, so he filled another cup of tea for her and said casually: "If you want to continue watching, you can stay a little longer. I have nothing else to do today. If you want to go back, you can." You can come and see it later when you have free time.”

Xu Jing felt somewhat regretful, but she also knew that these files were private government documents and it was impossible for her to take them home. She thought about it and said, "I have something to do when I go back, so I'll come back when I have time."
