Chapter 231 Obsessive-compulsive disorder

"Dresses?" Han Xu muttered to himself.

Guo Jia was standing next to him, and even though his voice was very low, he could hear it clearly, "Is there anything wrong with these skirts? Xiaolu's favorite thing to wear when she was alive was skirts, and every one of them was very beautiful."

Han Xu said casually, "It seems that the victims of Yaoyang's other three cases all wore skirts, right?"

Guo Jia nodded without hesitation, "Yes, the other three victims all wore skirts, and we found them at the crime scene. This is indeed a common point, but those skirts are different in color and style. Could it be that the murderer only targeted victims wearing skirts?"

Han Xu thought for a while, and slowly said, "This possibility cannot be ruled out, but relatively speaking, the possibility is not too great.

Serial killers like this usually have a stimulus source, that is, That is to say, he usually arouses the subconscious desire to kill when he sees something or does something.

Skirts may be the source of this stimulus, but if the colors and styles are different, there are people wearing skirts all over the street.

It is impossible for the murderer to suppress the most primitive impulse in his heart when there are stimuli all around. "

Guo Jia fell into deep thought after hearing this, and said after a while, "It is indeed the case. If I were the murderer, I would go crazy when I saw the skirt and would not even dare to go out. No wonder our director gave an order at that time to focus on checking the single men who rarely go out nearby!"

Han Xu always felt that Director Chen Zhongchen of Yunling Police Station was very capable. Now, after hearing what Guo Jia blurted out, he admired him even more.

Sure enough, there are people who are better than you!

Guo Jia paused, and then continued, "But unfortunately, we locked in several suspects at the time, but later ruled them out one by one. They either did not have the time to commit the crime or were too weak to do anything, and they did not meet the characteristics of the murderer."

Han Xu had long guessed that the result might not be very good, but he still did not give up any details, "Do you still have their investigation records?"

Guo Jia nodded, "If you want to see it, I'll go back and give it to you."

Han Xu nodded slightly, and then focused on the skirt in the closet.

If the murderer's stimulus source is not the skirt, then what is it?

The only common point of the four cases is that the victims were all wearing skirts, but the colors and styles were different. The victims' clothes were found at the scene of three crimes, but only Yang Lu's skirt was taken away by the murderer. Why is this?

One by one, the suspicious points are like eyes hidden in the night, flickering!

Han Xu felt a little overwhelmed, but his subconscious told him that Yang Lu's skirt must be the most critical breakthrough point.

It's a pity that no one knows what skirt she was wearing at the time? Why did the murderer take the skirt?

At first, Han Xu thought that the murderer took the victim's clothes because they were stained with some unfavorable evidence.

But now it seems unlikely!

Because in the other three cases, the murderer did it very neatly.

He even neatly folded the victim's clothes and put them aside before committing the violation.

When Han Xu saw the photos of those clothes before, he had an idea.

The murderer is likely to have some obsessive-compulsive disorder.

Obsessive-compulsive disorder is actually a type of anxiety disorder, and it is also a neuropsychiatric disease with obsessive thinking and compulsive behavior as the main clinical manifestations.

The characteristic is the coexistence of conscious compulsion and anti-compulsion!

In layman's terms, it means that people often do some meaningless or even impulsive things that go against their will. People with obsessive-compulsive disorder often know that these thoughts or impulses come from themselves and want to resist them, but they can't control them!

If the strong conflict between the two reaches a certain level, the patient will have great anxiety and pain, and even affect their study, work, interpersonal communication, and daily life.

But this kind of people are also very scary. When they execute a task, they often pay attention to every detail, such as cleaning the scene without leaving any dead corners.

"Do you think this guy has obsessive-compulsive disorder?" Han Xu tried to express his thoughts.

Guo Jia was stunned when he heard it, "What? Obsessive-compulsive disorder?! Why?"

But he quickly thought of the neatly stacked clothes at the scene, "It's not impossible! If the murderer has obsessive-compulsive disorder, it will be much easier to investigate. After all, not everyone has that kind of weird behavior."

"If the murderer did it on purpose, it's hard to say." Han Xu said casually while looking through the various skirts hanging.

This sentence was like a basin of cold water, which completely extinguished the fire of hope that Guo Jia had just ignited.

"No way? Is the murderer so perverted? Deliberately stacked the victim's clothes at the crime scene just to interfere with our investigation direction?" Guo Jia's scalp was numb again. No wonder he had found nothing after five years of investigation. According to Han Xu's words, the murderer was too scary and there was no solution.

"It's not impossible!" Han Xu looked back at Guo Jia, "This murderer is not only cunning, but also very intelligent. He is ahead of us in every step. It's like a Go game. We can calculate the changes after five steps, but this guy can at least calculate the outcome after ten steps."

"CTMD!" Guo Jia was a little confused and couldn't help but curse.

"But people are not AlphaGo. As long as the murderer is still one person, there will definitely be loopholes. We just haven't found them yet." Han Xu saw that Guo Jia was in a bad mood and couldn't help but cheer him up.

"Alas, I can't do it. The murderer has played me around," Guo Jia shook his head, still a little unmotivated.

"How can it be possible? You are so careful in handling cases, you will definitely find clues." Han Xu couldn't help but comfort him.

Guo Jia knew his own situation and said helplessly, "No matter how careful I am, it won't work. It's been five years, and there are still no clues?"

"Where there is a will, there is a way! When handling a case, don't lose your temper," Han Xu reminded again.

Guo Jia also understood this truth and changed the subject, "Don't you still have you! I believe you can catch the murderer."

"I'm not a god. This case is really difficult to handle. The murderer is much more powerful than I imagined." Han Xu carefully checked the wardrobe, turned his head and said to Guo Jia, and then focused on the laptop.

Guo Jia wanted to say a few more words, but felt that it was meaningless. Seeing Han Xu looking at the laptop, he casually said, "This computer is the latest model, but it's the latest model from five years ago."
