Detective: Open your eyes, I am handcuffed in the interrogation room.

Chapter 3 Footprint Analysis
In the interrogation room, several stunned eyes looked at Chen Yi.

One day to solve the murder that just happened?

I'm afraid even the criminal investigation experts from the Imperial City would not dare to give this guarantee.

How can a rich second-generation idler have the confidence to boast like this?
Besides, you are now a major suspect in this case!
Chen Yi looked at Zhou Yebin with a smile, waiting for his answer.

This case is actually not difficult. If Zhou Yebin is asked to investigate, the result should be available within a few days.

A little longer, ten days and a half month would be enough.

But he has an inherent advantage in this case.

What advantage?
Know the deceased very well.

A world-class detective who knew the deceased very well had enough time in one day to get to the bottom of this case.

Maybe, it can be shorter.

The premise is that he needs to have detailed on-site investigation reports and autopsy results, as well as the surveillance content of the only way to Liu Ge's house.

"Chen Yi, you need to understand the situation."

"Now, you are a suspect."

Zhou Yebin's voice was a little cold.

The police have not ruled out the other party's suspicion, and there is still a question about whether to release him or not. How can they let the other party intervene in the case?

Do you think this is filming a movie?

Chen Yi's expression remained unchanged, and he said calmly: "Captain Zhou, there are also footprints of a third person at the scene, right?"

These words made Zhou Yebin slightly shocked: "How do you know?!"

There were indeed footprints of a third person at the scene. This was the result obtained by trace inspection technicians after careful investigation.

As for who it is, we don’t know yet.

The person's height and weight can only be roughly determined based on the characteristics of the footprints.

Preliminary estimates suggest that it is a male.

Chen Yi smiled: "Didn't I tell you that I am not the murderer?"

"Based on this premise, there should be footprints of a third person at the scene, that is, the murderer."

"Unless the murderer deliberately wore leg gloves."

"However, this person was able to enter Liu Ge's home calmly and find an opportunity to kill Liu Ge with a fruit knife, which shows that the two knew each other."

"Liu Ge is not a person who pays attention to household hygiene. Guests never need to wear foot covers when they come to the house."

"If an acquaintance comes to the door wearing ankle gloves, it will only increase Liu Ge's suspicion and even vigilance."

"Therefore, there is a high probability that there are footprints of a third person at the scene."

This analysis surprised Zhou Yebin.

Although the logic is not difficult, it is not easy to figure it out in a short time.

This Chen Yi has something.

"Go on, what else do you know?" Zhou Yebin stared at Chen Yi and spoke.

Chen Yi continued: "If I guess correctly, you can reconstruct the crime scene based on the footprints and the location of the deceased's body. The murderer is most likely the third person."

"The reason why I was brought here for interrogation is just because there are my fingerprints on the murder weapon. I want to hear what I have to say."

After talking to this point, the young police officer next to Zhou Yebin was already surprised.

Clear mind, careful logic, accurate judgment.

The guy named Chen Yi in front of him is really not simple.

Then why were you so timid when you were first brought here?Pretending?
Zhou Yebin was silent for a while and said, "But you are still suspected of committing the crime."

"Since you are smarter than I thought, give me a reason to eliminate suspicion."

Chen Yi smiled: "Of course."

"Can you help me open the handcuffs? It's very uncomfortable."

"To be honest, this is my first time being handcuffed by someone else."

The feeling of being a suspect is not very good, but for Chen Yi, it is quite novel and a different experience.

Zhou Yebin was unmoved: "Let me hear what you say first, and then consider whether to open the handcuffs." Chen Yi said indifferently: "Okay then."

"Captain Zhou just got the fingerprint comparison results and took me to the city bureau. There must be a lot of work to be done."

"For example, deeper footprint analysis."

Zhou Yebin's eyes narrowed slightly, and he immediately understood what Chen Yi wanted to express.

At that moment, the way he looked at Chen Yi began to look different.

Being so familiar with criminal investigation techniques, how come this Chen Yi looks more like a policeman than a policeman?
Chen Yi watched Zhou Yebin's reaction and said, "It seems I was right."

Footprint analysis, also known as footprint analysis, is a legal term.

Footprint analysis is an important and indispensable part of criminal investigation.

such as.

Are the location of the footprints at the scene consistent with criminal activity?
Is the age of the footprints similar to the time of the crime?
Are the footprint attachments related to criminal activity?

Are there any connections between the footprints and other traces at the site?
and many more.

All of these have a great role in promoting the investigation of the case.

Zhou Yebin stared at Chen Yi for a while, turned his head slightly and said, "Let the technical department do an on-site overlapping footprint analysis immediately, and send the results over immediately."

Young police officer: "Yes, Team Zhou."

After saying that, he glanced at Chen Yi, turned around and left the interrogation room.

Zhou Yebin turned his attention to Chen Yi again and said, "I understand what you mean."

"If all the footprints of the third person are behind you, then your suspicion of committing the crime and being an accomplice can basically be ruled out."

Chen Yi nodded with a smile: "Captain Zhou is indeed an experienced criminal police officer. He is right."

What he wanted to express was footprint coverage.

New footprints step on old footprints. Most people may not be able to tell them, but the Criminal Investigation Team Technical Section can completely distinguish them.

If the third person's footprints are covered with your own footprints, it means that the third person came later.

After he left Liu Ge's house, a third man followed and killed Liu Ge with the fruit knife.

The time difference between before and after will not be too big.

That's why he was brought here to face interrogation as a suspect.

"There's no need to flatter him." Zhou Yebin leaned on his chair and waved to the nearby police officer, "Unlock his handcuffs."

"Yes, Team Zhou."

The police officer stepped forward, took out the key and released the restraints on Chen Yi's wrists.

Chen Yi felt a lot more relaxed and moved his hands a little.

"Thank you Captain Zhou, but it's too early to open the handcuffs for me now. The results haven't come out yet."

Zhou Yebin picked up the cigarette on the table and lit it. After slowly exhaling a puff of smoke, he said, "I choose to believe you. Besides, you can't run away."

Chen Yi chuckled: "That's true."

Once in the interrogation room, running was impossible.

Wearing handcuffs is just to prevent the suspect from doing excessive behavior.

As long as the suspect is relatively normal, calm, and has no problem communicating, most police officers will not handcuff you in the early stages of interrogation.

But after pleading guilty, handcuffs were indispensable.

"Mr. Chen, you seem to know a lot about criminal investigation." Zhou Yebin held a cigarette between his fingers and looked at Chen Yi.

Chen Yi lowered his gaze, stretched out his hand and said with a smile, "Can you give me one?"

Zhou Yebin didn't say anything. He stood up, picked up the cigarette case, came to Chen Yi, took out a cigarette and handed it over.

Also handed over was a lighter.

The lighter is a small dangerous item, and it was handed over to the suspect under trial rashly, which shows that Zhou Yebin has basically lost his vigilance towards Chen Yi.

"Thank you." Chen Yi said politely.
