A new police officer joins the team and solves a major dismemberment case

Han Xu was about to say something when he was interrupted by Qi Shen again!

"Officers, you guys are making it very difficult for me! You came here twice in one day. Do you think I'm not busy enough?" Qi Shen's resentment was even heavier than before.

Guo Jia explained a few words, but Qi Shen didn't listen at all.

"Okay, can't I go with you?" Qi Shen said, turned around and closed the security door, and walked towards the elevator first.

The three followed closely and returned to the unique pavilion.

"Brothers, what do you want to know? Can we finish it all in one breath? Aren't you tired of going back and forth?"

Han Xu took over the conversation, but his tone was very calm, "Mr. Qi, we want to know if your ex-wife Nie Xiaoyu had any items with butterfly elements when she was alive."

"Butterfly?!" Qi Shen looked at Han Xu in surprise, his eyes full of doubts, but soon became clear, "Oh, you know what, I seem to remember that Xiaoyu especially liked butterflies. Once she caught such a big one in the park, it scared me to death! I argued with her for a long time before she threw the thing away. It was too creepy!"

It was the first time that Qin Fen heard the word "creepy" used to describe butterflies, and he couldn't help but look Qi Shen up and down again.

Seeing this strange look, Qi Shen couldn't help but explain, "I have been afraid of insects since I was a child. No matter how beautiful the butterfly looks, it is also transformed from an insect. I feel sick when I see it!"

Han Xu saw that the topic was getting further and further away, and tried to get it back on track, "Have you ever seen similar objects?"

Hearing this, Qi Shen frowned tightly, as if trying to recall what happened in the past, but the result was counterproductive. After thinking for a long time, he still shook his head, "Sorry, officer, it has been five years, I really can't remember it, not to mention that Nie Xiaoyu knows that I am afraid of these things. Even if she likes them, she will avoid me."

Han Xu couldn't find any fault with Qi Shen's words, and he was a little hesitant about his own inference.

But he soon gave up this idea!

From a psychological point of view, serial killers usually have some common characteristics, such as an extreme desire for killing, or they can be said to be addicted to killing!

What's more terrifying is that this desire exists in the killer from the beginning. Of course, it may not have formed when the first murder was committed, but gradually evolved in the later period.

Obviously, in the Yaoyang Four Cases, the murderer also had an extreme desire for killing, but there was one thing that was very abnormal. The murderer killed four people in just two months, but suddenly disappeared. If there were no external factors, it would be difficult to explain.

In addition, this type of serial killer often has some abnormal needs, and this need usually comes from their own personality disorder.

Han Xu has done some research on this type of serial killer before. He thinks that in addition to these external manifestations, this type of serial killer is very likely to have a stimulus that awakens the killing!

In other words, the murderer of the Yaoyang Four Cases was stimulated by something, so he could not suppress his desire and committed killing.

And this stimulus is the common point of the four victims!

At first, Guo Jia thought that the stimulus was the skirt worn by the victim, but it was quickly denied by Han Xu.

Because skirts are too common, if the murderer killed crazily because of this stimulus, he would have collapsed long ago.

So in the next investigation, Han Xu focused all his attention on the stimulus.

Then the victim's belongings taken away by the murderer become the top priority!

Those items are very likely to be directly related to the stimulus!

The victim Yang Lu was taken away from her skirt, and Chen Xiaoran's missing brand-name handbag may also be related to the murderer.

Put these two things together, and a particularly obvious thing is about to come out!

That is the butterfly!

There is a colorful butterfly pattern on Yang Lu's skirt, and there is a bow decoration on Chen Xiaoran's handbag!

So when Han Xu saw the picture clues provided by Shen Liu, he suddenly realized it!

The real stimulus of the murderer is very likely to be butterflies, or items related to butterflies!

And this kind of serial killer often has long-term deformed and evolving fantasies!

This extremely deformed and perverted fantasy may be related to killing, or it may be related to sex!

So the murderer's target becomes a woman who is directly related to the butterfly element!

But this speculation is based on a psychological inference, and it is untenable without evidence.

Although the butterfly appeared twice, it might just be a coincidence!

As the saying goes, it can happen once or twice, but not three or four times!

The appearance of the butterfly once or twice can be said to be a coincidence, but what if it appears for the third or fourth time?

Then the answer is obvious!

The butterfly is the most critical point, and it is also the Achilles' heel of the murderer in the Yaoyang Four Cases!

But unfortunately, Qi Shen couldn't remember what items Nie Xiaoyu had with butterfly elements.

Qin Fen patted Han Xu's shoulder when he saw this, "It's okay, isn't there Wang Yuan! Let's continue to investigate, I believe the truth will soon surface."

Guo Jia nodded, "Don't be discouraged, I think your inference is very rigorous, this serial killer must be related to butterflies, almost!"

Qi Shen, who was kept in the dark, frowned when he heard this, "You mean the murderer is related to butterflies?"

Guo Jia knew he had made a mistake and laughed, but Qi Shen got the point.

"Wait a minute, I saved all the photos I took with Nie Xiaoyu before, maybe there are things you want on them."

After Qi Shen said that, he took out his mobile phone, gestured, and then handed over an unlocked picture folder.

Han Xu was overjoyed to see the light at the end of the tunnel, and took the phone and started to look through them one by one.

The other three people also came over nervously...

The heads of several old men were crowded together, which was a different scene.

However, Qin Fen and the other two could not keep up with Han Xu's speed of looking up. When they saw a photo, Han Xu had already turned it over quickly before they could think about it.

"Fuck, Han Xu, turn it slowly, why do I feel that my old eyes can't keep up!" Qin Fen couldn't help but complain.

Guo Jia rubbed his eyes hard, and immediately skipped several photos, and couldn't help but look horrified.

Qi Shen couldn't bear it any more. He looked at it twice and was so dizzy with the speed that his head was full of stars. He simply gave up and withdrew from the battle.

How could they know that Han Xu had unknowingly activated the dynamic vision granted by the system, and his browsing speed was amazingly fast!
