Detective Training Manual

　　 Liu Chen's pupils widened slightly.

　　 He immediately leaned against the wall, first took out a flashlight, then lifted his foot and took off his shoes.

　　 Borrowing the light from the flashlight, he saw that in the cracks in the soles of his shoes, there were some small black spots, which were the same as the dirt found by the police officers. They were stepped on when they came in.

　　 Liu Chen put down the flashlight, pondered for a few seconds, then put on his shoes, and said to the police officer who just came up: "Go and inform the brothers and let everyone see if there is any dirt on the soles of their shoes."

　　 Then, he directed at the two police officers on the side, Zhou Yan and Li Huan and beckoned: "Go, let's go to the first floor."

　　 In this way, a few people quickly reached the first floor. At this time, the lights in the lobby on the first floor had been turned on. It is estimated that a police officer found the power switch.

　　 Besides, these police officers didn't know where they took out a few light-distribution lamps, illuminating the ground on the first floor.

The ground of the first floor of this office building is not tiled, and it is still in a “rough” state, so the mud debris has seeped into the rough cracks of the concrete floor. Under this kind of light, everyone can finally see Up.

　　 Liu Chen squatted down and used his gloved hands to pick up a few mud debris, which was very soft and very dark.

　　 "Where did this mud... come from?" He muttered to himself.

　　 Suddenly, a police officer came over again.

　　 "Detective Liu, we met this person nearby. He was behaving suspiciously, and he kept wandering around."

　　 said, an uncle in his fifties was brought over.

　　 This person is not tall, more than 165 points, beer belly, fading, and he is full of alcohol.

　　 "Who are you?" Detective Liu got up and asked.

　　 "I...I..." The man was obviously flustered and hesitated for a long time: "I am here to watch the door." He finally said it.

　　 "Oh? The doorman?...That's the policeman brother, you go to the guard room to see if there is a photo of him." Detective Liu said to a police officer on the side.

　　 The police officer went quickly and came back quickly. He also held a one-inch photo taken off the duty list in his hand.

　　 is the uncle who is thankful.

　　 Liu Chen glanced at the photo: "It was not posted recently."

　　 "No!" the police officer said plainly.

　　 Well, looking at it this way, this uncle should really be the doorman.

　　 Detective Liu stared at the uncle again and asked, "What are you wandering around?"

　　 "I just went out...to eat. When I came back, I saw a police car, so I was a little scared, so I wanted to see what happened nearby?"

　　 Liu Chen looked at the other person's undecided horror, and then smelled the smell of alcohol on his body: "Eating? How can I eat until this time?" His voice was deliberately raised.

　　 This scare, the uncle janitor was also taken aback, and quickly confessed: "I'm sorry, sorry, I should be on night shift in the guard room, but I ran out for a drink."

　　 "Hey, don't stick to your post, do you know someone in your building just died?"

　　 This sentence made the uncle so scared that he could not stand still: "Dead...dead?"

"Well, someone will tell you the specific situation when you make the transcript. And because you didn't know where you were just now, so you have to be investigated. But let's not talk about it now... ."

　　 said, Liu Chen pointed to the ground behind him: "Do you know what this is?"

　　 The uncle Xieding was taken aback: "This...this is the ground."

"Tsk, I'm not asking you about the ground, but about these little mud crumbs on the ground." As he said, Liu Chen took out the little plastic bag containing the mud from his pocket: "Well, do you know what it is? ?"

　　 Uncle looked at the plastic bag, but didn't hesitate: "I know, this...this is flower mud."

　　 "Flower mud?"

"Yeah." The man nodded, "Yesterday afternoon, a few people moved a large pot of flowers. It must be so big!" He said, and measured it with his hands: "But just walked in, If a person didn't hold it, it was broken, and the muddy flowers were scattered all over the ground."

"Then?"

　　 "After that, I will clean it, what else can I do? I finally clean it up until the end of get off work."

　　 "That's it." Detective Liu nodded.

　　 There is definitely no way to clean up this kind of floor without tiles. At most, it is just fine with the naked eye. Therefore, a lot of finely divided mud remains.

　　 And because they use ‘sweep’, the coverage of these mud pips is extremely large. Once you pass by, you will definitely step on it.

　　 Thinking of this, Liu Chen took out the pair of slippers again. At this moment, the pair of shoes had been put in a special evidence plastic bag.

　　 Through the bag, Liu Chen confirmed that there was no dirt on the shoes.

　　 This is strange.

　　 If the flowerpot was broken yesterday afternoon, then when the deceased climbed onto the roof today, the shoes would definitely have mud on the shoes.

but.

　　 In other words, the deceased was on the rooftop before yesterday afternoon.

　　 But why did he go to the rooftop yesterday and only jumped off the building today?

　　 Still, there is something strange about this case?

　　 Also, what the **** is this pair of strange slippers? How could anyone walk back and forth in these slippers?

　　 The case was easy to handle, but it seemed that a lot of problems suddenly appeared. UU reading www.uukanshu.cóm

　　 "Hello~" Liu Chen said to the uncle janitor again, "Do you have a camera?"

　　 The uncle shook his head: "We are all decades old buildings, who would be equipped with a camera?"

　　 "Then...in the past few days, have you seen any strange people entering the building?"

　　 Uncle still shook his head: "No."

　　 But he said no, but the actual meaning should be... he didn't even look at it.

　　 Originally, like his job, how could he perform his duties every day, just mess around. As long as someone is not pushing a bucket of explosives inside, he probably won't pay attention at all.

　　 Liu Chen seems to have realized this too: "Well, let me change the question, have you ever been on the rooftop in the past few days?"

Uncle 　　 still shook his head.

　　 "Well, it is the same as if I didn't ask." Liu Chen had long known this and thought: "Well, take him over to make a transcript, remember, don't let him go when you are done."

　　 Liu Chen, as always, never let go of anyone involved in the incident.

　　 In this way, the case seems to have reached a certain stalemate.

　　 And at this time...

　　 "Yes... I'm sorry, I have a question." A voice suddenly sounded.

　　 Everyone turned their heads and looked in the direction of the voice, and found a very quiet Li Huan slowly raising his hand, as if speaking in a class.

　　 "What's the problem?" Liu Chen was taken aback and asked.

　　 Li Huan hesitated: "If the deceased jumped from the 12th floor, will he be so close to the building when he lands? I think the position of the body is only about 1.5 meters from the wall."
