In the interrogation room, a few stunned eyes looked at Chen Yi.

One day, solve the murder that just happened?

I'm afraid that the criminal investigation experts from the Imperial City are here, and they don't dare to play this package ticket.

A rich second generation who is idle, where does he have the confidence to brag about this bull?

Besides, you're 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, there should be a result in a few days.

A little longer, ten days and a half months is enough.

But he has an innate advantage in this case.

What are the advantages?

Knows the deceased very well.

A world-class detective who knows the deceased very well, wants to get to the bottom of this case, and one day is enough.

Perhaps, it could be a little shorter.

The premise is that he needs to grasp the detailed on-site investigation report, as well as the autopsy results, and also understand the monitoring content of the road to Liu Ge's house.

"Chen Yi, you have to figure out the situation."

"Now, you're a suspect."

Zhou Yebin's voice was a little cold.

The police have not ruled out the suspicion of the other party now, and it is still two to say whether to let the other party go, and how can they let the other party meddle in the case.

Do you think it's a movie?

Chen Yi's expression remained unchanged, and he said calmly: "Captain Zhou, the scene is ...... There's a third man's footprints, right? ”

This remark made Zhou Yebin slightly shocked in his heart: "How do you know?!" ”

At the scene, there were indeed footprints of a third person, which were obtained by trace examination technicians after careful investigation.

As for who, it is not yet known.

Only based on the characteristics of the footprints, the height and weight of the person can be roughly judged.

According to preliminary estimates, it should be a male.

Chen Yi smiled: "Didn't I say it, confirm that I am not a murderer." ”

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

"Unless, the murderer deliberately wears a foot cover."

"But this person can calmly enter Liu Ge's house, and he can also find an opportunity to kill Liu Ge with a fruit knife, which shows that the two know each other."

"Liu Ge is not a person who pays attention to household hygiene, and guests never need to wear foot coverings when they come to the door."

"An acquaintance comes to the door, if he comes with a foot cover, it will only increase Liu Ge's doubts and even vigilance."

"Therefore, there is a high probability that there are footprints of a third person at the scene, unless they have been deliberately cleaned up."

This analysis surprised Zhou Yebin.

Although the logic is not difficult, it is not easy to figure it out in a short period of 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 guessed correctly, after the footprints at the scene and the location of the deceased's body, the murderer is most likely this third person. ”

"The reason why they brought me here for interrogation is only because there are my fingerprints on the murder weapon, and I want to hear what I say, and I can't rule out the possibility of being an accomplice."

Talking about this, the young police officer next to Zhou Yebin was already surprised.

Clear mind, meticulous logic, accurate judgment.

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

Then why was he so timid when he first brought it here? Loaded?

Zhou Yebin was silent for a while and said, "But you are still suspected of committing a crime." ”

"Since you're smarter than I thought, give me a reason to rule out suspicion."

Chen Yi smiled: "Of course." ”

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

"To be honest, it's the first time I've been handcuffed by someone else."

It doesn't feel very good to be a suspect, but for Chen Yi, it's quite novel, and it's a different experience.

Zhou Yebin was unmoved: "Listen to 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, so he took me to the city bureau, and there must be a lot of work to be done."

"For example, a deeper analysis of footprints."

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

At that moment, he looked at Chen Yi's eyes and began to be different.

is so familiar with criminal investigation techniques, how can this Chen Yi be more like a policeman than a policeman?

Chen Yi watched Zhou Yebin's reaction and said, "It seems that I am right. ”

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

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

Like what.

Is the location of the footprints at the scene consistent with the criminal activity?

Are the footprints similar to the time of the crime?

Are the attachments of the footprints linked to criminal activity?

Is there a connection between the footprints and other traces at the site?

Wait a minute.

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

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

Young Officer: "Yes, Team Chow. ”

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

Zhou Yebin put his eyes on 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 worthy of being an experienced old criminal policeman, what he said is good." ”

What he wanted to express was footprint covering.

The new footprints are stepping on the old footprints, and ordinary people may not be able to see them, but the technical section of the criminal investigation team can be completely distinguished.

If the footprints of the third person are covered by his own footprints, it means that the third person is later.

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

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

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

"You don't have to shoot sycophants." Zhou Yebin leaned back in his chair and waved his hand at the nearby policeman, "Open the handcuffs for him." ”

"Yes, Team Zhou."

The police officer stepped forward and took out the key to remove the restraint on Chen Yi's wrist.

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

"Thank you Team Zhou, but now open the handcuffs for me, isn't it a little early, the results haven't come out yet."

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

Chen Yi chuckled: "That's the same." ”

When it came to the interrogation room, it was impossible to run.

Handcuffs are just to prevent the suspect from acting aggressively.

As long as the suspect is relatively normal, calm and communicative, most police officers will not handcuff you at the beginning of the interrogation.

However, after the confession, handcuffs are indispensable.

"Mr. Chen, he seems to know a lot about criminal investigation." Zhou Yebin held a cigarette between his fingers and watched Chen Yi speak.

Chen Yi looked down, stretched out his hand and smiled: "Can you give me one?" ”

Zhou Yebin didn't speak, got up and picked up the cigarette case and came to Chen Yi, took out a cigarette and handed it over.

At the same time, there was also a lighter.

The lighter is a small dangerous goods, and it was rashly handed to the suspect on trial, indicating that Zhou Yebin basically had no vigilance against Chen Yi.

"Thank you." Chen Yi said politely.
