"Huh?" Detective Liu seemed to have finally found some clues, so he walked over.

In the past, I didn't forget to tell Zhou Yan and Li Huan not to come with me.

The slippers were the only thing left by the deceased that was still intact, and if there were any clues on them, he didn't want people to accidentally destroy them.

Detective Liu walked to the slippers alone, cautious all the way.

He bent down and carefully circled the slippers, and then put on his gloves and picked them up.

This is a pair of uncommon slippers, without any floral patterns on it, very light, a little worse than the average slippers, and the bottom is not thick.

Seem...... It's the kind of disposable slippers that are used in hotels.

Of course, not to that extent. Otherwise, when the wind blows, it will be blown away.

Immediately afterwards, Detective Liu carefully inspected the floor of the rooftop, and also stretched out his head to check the wall on the outside of the rooftop.

After doing this, he also came to a conclusion.

That's ...... There is nothing special about it.

None of the mechanisms, gadgets, or things that I had conceived before, such as those that existed.

"emmm ......" After this inspection, Liu Chen also pinched his chin and sorted out his thoughts a little.

In fact...... Under normal circumstances, this case is a very ordinary suicide incident.

The reason is simple.

First, there were no Tibetans in the building, which ruled out the possibility that someone had pushed the deceased out of the roof.

Second, there doesn't seem to be any sign of a mechanism on the rooftop. In other words, it is impossible for the murderer to let the body fall in his own absence.

Of course, whether there is an organ or not depends on the search of those police officers before making a conclusion.

Anyway, at this moment, this case looks like a suicide for the time being.

Then look at the slippers on your hands.

Looks...... This should be the slippers of the deceased.

According to statistics, if a person wants to commit suicide by jumping off a building, and he has been planning for a long time, then the probability of him taking off his shoes before jumping off the building can reach 20%~30%. Men are dressed neatly and have a tie of more than 40%. And the chance of women putting on makeup before jumping off the building is more than 70%.

The specific reason should be that before death, people always want to draw a beautiful end to their lives.

And this slipper...... The biggest disadvantage is that you don't follow your feet, so the thought that in the process of jumping off a building, the shoe may be thrown in mid-air and then smashed on your own broken head, which feels too uncomfortable.

Therefore, it is quite reasonable for the deceased to take off his shoes.

As for whether the shoes are placed neatly or not, and which direction they are facing, in fact, in most cases, it doesn't matter, after all, they have been taken off by the initiative, and the deceased can put them as he likes.

......

And just when Liu Chen was seriously checking the slippers, Zhou Yan also turned out the detective notes in his pocket.

Anyway, I can't go over now, so it's better to stand and see what the gang in the book are shouting about.

This group of people, one by one, is like a pervert, and when they see the case, the thief Jill is excited.

Open the book...... Really......

[Eternal Festival: The prison is full of squatting pits, no toilets]

“？？？ Is this man talking about his time in prison? No, it's been delayed for more than half a month, is this person's signal so bad? ”

[Handsome Qingfeng: This boyfriend is explosive]

"What's boyfriend power?"

[Ethereal Root also needs to cultivate immortals: Zhou Yan! ] On the ground on the first floor, there is some very strange black soil, very finely broken, grain by grain. 】

Zhou Yan raised his eyebrows: ", I'll just say it, I have immortal cultivators in this book!" But...... What is black dirt? On the ground on the ground floor? No, why didn't I see it when I went upstairs? ”

[Pandas don't drink: There is a strange black dirt on the ground on the first floor, and no one notices it~~]

“emmm...... It looks like there really is. ”

Zhou Yan raised his head and looked at Detective Liu, who was still fiddling with the slippers not far away...... He hesitated for a moment, wondering, should I tell him this clue?

Nonsense, of course you have to tell! This is a case of human life, whether you want to get involved or not, but if you have a clue, then you must say it, we can't be born again, so we won't talk about civic duty, right?

"Uh, that...... Detective Liu~" Zhou Yan stood in place and waved his hand.

"What?" Liu Chen didn't raise his head, staring at the slippers and answered.

"Nothing matters...... It's just that there is some dirt on the ground on the first floor, which you shouldn't have noticed, so I'll remind you. ”

"Oh?" Liu Chen turned his head sideways and looked at Zhou Yan: "Dirt? ”

"Hmm......" Zhou Yan nodded.

And that's when ...... Suddenly, a police officer stepped onto the rooftop.

"Detective Liu, we found this on the first floor of the building." He stood at the entrance and exit of the rooftop, and very professionally did not take an extra step inside, but raised his hand...... In his hand is a small sealed transparent plastic bag.

Liu Chen immediately walked over, picked up the small plastic bag and looked at it.

Inside...... It's some very fine, very fine black crumb.

But the volume is too small, not much larger than gravel. This kind of thing, if you put it on a white paper, you can still see it, but if it is on the ground, and it is not turned on the light, the average person will never be able to see it.

"Strange...... Dirt? Why is it so small? Liu Chen kneaded these small pieces of mud through the plastic and muttered, then turned his head to look at Zhou Yan: "How do you know that there are these things on the first floor?" ”

"This ...... I saw it. Zhou Yan replied, of course he couldn't say that it was the people in the book who told him.

"Can you see this?" Liu Chen frowned slightly, looked at Zhou Yan, probably thinking, is this guy a cat?

"Well, if you think of anything again, remember to tell me in time."

Liu Chen looked at Zhou Yan and said thoughtfully.

That's when ......

He was suddenly stunned! It's like remembering something.

Liu Chen immediately picked up the slippers in his hand, then turned them upside down and looked at the soles.

And on the sole ...... Very clean, nothing but some dust.
