Zhou Yan asked, not that he wanted to be nosy.

Instead, he wants to understand what the detective case handling process in this world is.

Liu Chen raised his eyes and looked at Zhou Yan.

"Don't worry, I'm just saying that it may be suicide, whether it is suicide or not, it still needs to be investigated."

He seemed to have a good temper, and continued to explain to Zhou Yan: "In the process of investigation, I will first try to solve the case according to my ideas, if I have doubts, or if the evidence chain is incomplete, I will report it, and soon a higher-level detective will come to deal with me." ”

Zhou Yan nodded, it seems that a detective with a slightly lower level can only deal with some relatively simple cases.

For example, jumping off a building to commit suicide, falling off a cliff and so on.

But they will not presumptuously characterize the incident, but first observe the scene, collect evidence, and as long as they find something wrong, they will report it and let a higher-level detective take over the incident.

Then someone may ask, what if the low-level detective is a fool, he mistakes the murder for suicide and does not report it to his superiors?

Wake up, people who can pass the detective exam won't be stupid enough to do that.

At this time......

"Detective Liu!" A police officer rushed over: "The whole building has been checked, and there is only one entrance." ”

The officer pointed to the exit of the building next to him.

"Hmm......" Liu Chen nodded, and then looked at Zhou Yan: "You have been here since the fall of the dead, and you have never left, right?" ”

"Yes." Zhou Yan replied.

"Then you didn't see anyone coming out of the building, did you?"

Zhou Yan shook his head: "No." ”

Liu Chen wrote a few strokes in his small notebook, and then looked at the police officer: "Is there really this one exit from the building?" Can't you get out of the building from a window or something? ”

"No way, the windows of every room down from the fourth floor down have been equipped with guardrails, and it's a style that can't be climbed at all, unless someone can jump down from the height above the fourth floor, the only exit can only be taken to exit the building."

The officer affirmed.

The police officers in this world, although they don't handle cases, are extremely good at collecting evidence, investigating the scene and other work, they say that there is only one exit, then there must be only one exit.

"Okay~" With a snap, Detective Liu Chen closed the small notebook: "Since no one has left this building from the beginning to the present, there are only three possibilities."

First, the deceased committed suicide.

Second, the murderer is still hiding in this building.

Third, what kind of mechanism props did the murderer use, so that the corpse could fall on its own in his absence. ”

As he spoke, he straightened his collar.

"Let's go, let's go inside the building."

When Zhou Yan heard this, he also nodded and said, "Okay, then I won't bother." With that, Zhou Yan turned around and was about to leave.

"Ouch, huh?" Detective Liu hurriedly stopped Zhou Yan: "What are you leaving?" ”

"Huh?" Zhou Yan was stunned. Although he is now a detective assistant, he has no idea of getting involved in the jumping case: "Didn't I tell everything I saw, why am I staying here?" ”

"How do you know you're talking about all?" Liu Chen asked rhetorically: "In the process of being frightened, the credibility of what a person says is not high, maybe you will remember some details after a while."

Moreover, you are the only witness, how can it be so easy to let you go.

What if this is not a case of jumping off a building, but a homicide, and you are the complicity of the murderer? ”

Zhou Yan's whole person was not good: "Do you think so much? If I'm colluding, I'm going to call the police? ”

"Maybe you're just using the habitual thinking of 'the murderer won't call the police' to confuse the public." Liu Chen said again: "Anyway, you just can't go, you have to go to the roof with me to have a look, maybe you will really remember some other details when you look at the scene." ”

"I can think of a fart detail, I just saw the moment the body fell, only a second or two at most." Zhou Yan shouted weakly: "Besides, how do you know that the deceased jumped from the top of the building, in case he jumped from the window on the 12th floor?" ”

“emmm...... That's right, okay then, you can go through all the rooms with me. Liu Chen said.

Zhou Yan can't wait to give himself a mouthful, thinking about what kind of mouth he has?

And that's when ......

"I ...... Can I go up with you? A timid voice rang out.

When Zhou Yan heard this voice, he was shocked, he turned his head in disbelief, and then saw Li Huan standing behind him.

She was wrapped in a blanket, as if she was still a little frightened, but her eyes looked at Detective Liu expectantly.

Zhou Yan slapped himself in the face.

Well, he easily understood Li Huan's idea of this girl's film.

A detective novelist, when she encounters a real case, how can she let it go so easily.

Even if it is a simple jumping case, even if you are very scared, even if you are panicked, it is absolutely impossible to miss it.

Liu Chen glanced at the little girl in front of him, and probably felt that this girl was also a witness......

"Okay, let's come along." He said.

I said...... It's just a little girl, what are you taking her for? Zhou Yan shouted.

Liu Chen glanced at Zhou Yan: "I can understand your feelings as a boyfriend, but it is the duty of every citizen to assist the detective in the investigation." ”

"I'm not his boyfriend."

"It's not your boyfriend, what do you care so much about. Come with me! ”

......

As I said before, the whole building is already in a state of no one, and in order to save electricity, the elevator is also closed after work.

If you want to go upstairs, you have to climb the stairs.

Because the light was very dim, no one noticed that on the ground on the first floor, there was some very strange black soil, very fine, grain by grain.

People walked over and stepped on the soles of their shoes, but the particles were very small, so they didn't notice it for the time being.

Walking in the front were Zhou Yan, Li Huan, Detective Liu, and two accompanying police officers.

The rest of the police officers took various tools and carefully searched every room on every floor.

The specific operation is that a special person has found the contact number of each company owner in this building through a remote operator, and then calls one by one to explain the situation.

After obtaining consent, there is a person who picks the lock quickly and is responsible for opening the door.

Zhou Yan was shocked by the speed of unlocking, if this person was not taken in by the police force and put into society, wouldn't it be easy to steal something in the middle of the night.

Anyway, after unlocking the lock, the police went in, checked every corner of the house without destroying any facilities, and did not forget to put the door on when leaving.

Under this kind of search, the murderer must have nowhere to hide.

And just like that, layer after layer......

Soon, the group came to the rooftop......

It's very empty, and there is nothing to hide, just glance at it, you can know that there must be no Tibetans.

But...... Although no one ......

But on the edge of the rooftop, there is a pair of white slippers......
