Young detective case book

It was almost eleven o'clock when Suye left People's Park.

There was a dull pain in his stomach, and his head was a little dizzy, so he suddenly remembered that he hadn't eaten breakfast yet.

After seeing the corpse that could only be described as "terrible" just now, he really didn't have any appetite.

At the canteen at the entrance of the park, I bought a box of chocolates of unknown brand.

Peel off the aluminum foil package, break off a small piece and put it in your mouth. The sweet, greasy and slightly bitter taste melts on the tip of your tongue.

Before he knew it, he thought of Ou Yuchen again. Ou Yuchen didn't eat much chocolate.

Although he likes to enjoy food and food, he has no interest in food that has been processed through too many industrial processes and added a lot of messy additives.

Su Ye remembers that on a certain sunny afternoon in a certain year and a certain month, Ou Yuchen lay lazily on the bed, casually flipping through a cookbook.

As if he suddenly remembered something, he sat up, threw the recipe aside, smiled at Suye, and blinked happily: "Suye, do you know what the original intention of the food itself is?"

Suye was sitting at the desk, resting his chin on one hand, and reading a book.

A bloody, disgusting book with illustrations full of broken limbs and remains, which is absolutely impossible to see or buy in the market, "Inside/Reference to Major and Important Cases in the Public Security System"——Shao ​​Ren showed it to him.

Facing such an inside/reference book, Su Ye had absolutely no interest in discussing food issues with him, so he kept silent.

"Let me tell you," Ou Yuchen smiled with crooked brows, beautiful pupils shimmering, and a high-spirited look that makes people unable to take their eyes off him. He talked triumphantly, "Food originally exists to fill the stomach. of.

However, the more expensive and the more refined the food is, the farther away it is from its original purpose.

Don't you think it's funny? "

Suye remembered that not long after arriving at Su's house, Ou Yuchen had said such philosophical words to him, that time it was about architecture.

At that time, Suye thought, Grandpa didn't choose the wrong person, Ou Yuchen was really outstanding.

The bewitching language, the perfect voice line with metal texture, and the perfect appearance that looks like it came out of Japanese animation, it exists simply to destroy other people's self-confidence.

It's just a pity that those architectural models collected by Ou Yuchen were all buried in the flames together with Sister Lan.

Thinking of that unfortunate woman, Suye sighed softly.

Inevitably, he thought of the victim he had just seen.

Diagonally across the road is Big B.

Today is the third day of the National Day holiday, but there are also students in twos and threes who come in and out from the school gate, each one full of vigor and youth.

It is not difficult for Suye to imagine that the woman who was massacred a few hours ago originally had the same youth and dreams as them, but ended her fresh life in the most tragic way.

Just now, Shao Ren suggested that Ye Zihui drive him home, but he refused.

He wanted to take a walk to settle his chaotic thoughts.

Before leaving, he expressed his judgment to Shao Ren: "I think the murderer is a male, aged between 22 and 35, with a strong body and neat clothes.

The family lives in this city.

He has a steady job, a steady source of income.Work cautiously, conscientiously, and diligently.

Familiar with crime scene investigation work, probably a detective novel lover, or have engaged in a career related to the law. "

After thinking about it, he added, "The murderer may have a few scratches on his left arm."

Shao Ren asked in surprise: "Can you tell me, how did you make these judgments?"

Su Ye calmly explained: "The murderer of the rape/murder case is a man, there is nothing to say about that.

The judgment about his age is because of the murderer's corpse abuse.

This behavior shows his strong venting and resentment.

Criminals with this kind of emotion are generally not too young, nor can they be too old.

If it is too small, it will not be so calm when committing crimes, the method of committing crimes will not be so methodical, and the crime scene will not be cleaned so neatly.

This murderer has already done several cases, all of which were in open public places, but he was neither discovered nor left with any clues.

His mental quality and behavior ability can be seen. "

Shao Ren thought about his words and nodded silently.

Su Ye added, "If he was too old, he should have committed the crime long ago, and he wouldn't wait until now.

Because this kind of paranoid and resentful emotion cannot be formed overnight, it needs a long-term accumulation and explosion process.

Just like Ted Bundy.

Also, referring to the age of the victim, we can also infer that the murderer should belong to this age range.

What he hates are female college students who are around 20 years old, so of course he should not be too young, nor should he be too old. "

Shao Ren nodded again.

Su Ye continued to explain, "In the first murder case, the murderer attacked the victim from behind with a wooden stick, so it didn't take much physical effort.

I noticed that the victim in the second case was strangled to death, and the victim in the third case was strangled to death.

Whether strangled or strangled, you must have an absolute advantage in physical strength.

Especially the No.3 victim, I read on the information that she was a member of the school badminton team and was 1.6 meters tall.

Such an adolescent girl, who often participates in sports, should have good physical strength and endurance.

So I judged that the murderer was a strong guy.

As for his personality and occupation, it can be seen from his patience and meticulousness in cleaning the scene. "

"What about the scratches? How did you infer that there were scratches on his left arm?" Shao Ren said doubtfully, "As a result of the forensic autopsy, no victim's skin tissue was found to be extracted from the fingernails of the suspected murderer."

Suye looked at the maple forest not far away, and said very slowly: "Then you should notice that the No. trash can."

"Ah."

"Her right index finger and middle finger, the fingertips are all tattered."

"Because it was found in a trash can and there were signs of biting, so we suspect it was done by rats."

"Maybe the rat did bite her finger, but it's also possible that the killer deliberately made a rat bite.

Or, after the murderer had done it, the rat did it a second time. "

Su Ye's cold voice slipped into Shao Ren's ears, making him surprised and unbelievable. After all, there was no evidence to support Su Ye's conjecture.

As if seeing through his thoughts, Suye explained again, "The reason why I have this hypothesis is because I am very puzzled."

"What are you wondering about?"

"Let's just assume that the victim, like many people, used his right hand most of the time.

Then when the murderer grabbed her neck and wanted to strangle her, she would instinctively struggle.

In view of the limited range of activities, the most likely thing for her to cause harm to the other party is to leave scratches on the left arm of the murderer with her right hand.

When making scratching movements, the fingers that mainly perform aggressive behaviors are the index finger and middle finger.

Don't you think it's a coincidence that these two fingers were gnawed to pieces by a mouse? "

Shao Ren didn't say a word, but he already believed in Su Ye's almost unbelievable conjecture.

After pondering for a moment, Suye said again, "There is one more thing I can't figure out."

"Oh, what's up"

When Shao Ren asked, Su Ye showed a hesitant look again: "The murderer is very cautious and cunning, and he doesn't want to be caught."

Shao Ren thought, nonsense, which criminal wants to be caught?

Su Ye continued, "The police didn't realize that these cases were committed by the same murderer at first."

"Yes." Shao Ren nodded a little ashamedly, "We did make a mistake."

"What I mean is..." Suye said softly, "Wouldn't it be better for him to let the police misunderstand? It would be wrong to detect the reverse, wouldn't it be safer for him?

So, why did he deliberately leave English letters and numbers to remind the police to investigate the case together? "

"As I said, maybe he is deliberately provoking the police, just like Jack the Ripper, who likes to send letters to the news media to announce his existence." Shao Ren said.

"But, don't forget, he's not doing Jack the Ripper, he's Ted Bundy.

In fact, as long as he continues to commit crimes, it won't take long, even if he doesn't deliberately remind, the police will link several cases of female college students being raped/killed together. "Suye retorted.

Shao Ren frowned: "You mean..."

"I felt that he was very anxious, lest the police mistakenly think that the murderer was not alone.

He handled the scene cleanly, saying he didn't want to be caught.

But he didn't want the police to disperse the direction of detection.

This seems really contradictory. "

Shao Ren murmured, what Su Ye said made sense, for the murderer, the police investigation, going astray is the most beneficial for him.

Then, his deliberate reminder is worth pondering.

After talking with Shao Ren, Suye left alone.

It was nearly noon, and the sky was still gloomy, with leaden gray clouds covering the earth densely.

When the wind blows, I feel a deep chill.

The branches above the head rattled and shivered in the desolate autumn wind.The dead leaves at the feet swirled up and down.

The road was empty and there was no one there.

Su Ye walked slowly, he thought, did the murderer also come to the park through this road?

How did he blend in with everyone without anyone noticing him?
