All the doors and windows are buckled from the inside, the first thing the police think of is the ladder, but there is no trace of a ladder on the walls around the house, the police have extracted a large number of shoe prints on the roof and in the room, these shoe prints belong to two kinds, one is the soft-soled old man's shoes, the other is the slippers, these two pairs of shoes were found by the police, and Zhou Xia's body tissue was extracted from the shoes, and it is believed that she is alone.

The fingerprints at the scene are only Zhou Xia's.

There are no traces of cleaning in the house.

There was no second person in the house.

But the injuries on Zhou's head clearly indicate that she had suffered serious violence before her death, and that this was a complete murder, not a suicide.

"How can there be no footprints? Who walks without leaving footprints? Zhang Zhang didn't believe that such a thing could happen at all, "unless the suspect is floating in the air." ”

"Isn't that a ghost?" Yue Yang said.

It is rumored that the ghost walks without touching his feet and keeps floating in the air.

At this time, it was completely dark, and although there were still people watching, the mention of ghosts still sent chills down the spine.

Sophie glanced at Yue Yang with disdain, and said, "How can there be a ghost, are you stupid." ”

"Then you explain why there are no footprints? How did the suspect get in and how did he get out? ”

Zhang Zhang thought for a while and said: "It's easy to explain when you go in, if the suspect knows the victim and knocks on the door, it's okay, and the door bolt is intact, which means that he knocked on the door and entered, but how did he get out?" The doors and windows are closed, and I have checked that the railings of all the windows are in good condition, and it is impossible to remove them easily, and how to explain this footprint? Why are there only the victim's footprints at the scene? ”

Tang Tao had already seen the clues, and asked with a smile: "How are you sure that they are all victims?" ”

"I see!" Sophie understood it at all, "The reason why we couldn't find the suspect's footprints was because the suspect was wearing Zhou Qin's shoes to commit the crime." ”

"That's right, see what this is?"

Tang Tao pointed the flashlight at a shoelace on the fence wall, "There should be a pair of shoes hanging here, I think the murderer also stumbled upon this pair of shoes." ”

"You mean Zhou Xia has two pairs of identical shoes?" Sophie asked.

"Yes, these shoes are supposed to be what she wears to work, aren't you a footprint expert? Why didn't you do what you did professionally? ”

It's not that Sophie doesn't want to investigate, it's that she can't intervene, after all, this is someone else's place.

"Even so, how did he leave?"

"Leave from the rooftop."

Zhang Zhang took out the photo of the roof door and glanced at it, nodded and understood what Tang Tao meant.

"Let me explain to you, the main function of the hut on the roof is to ventilate, for this hut will leave a lot of holes, the suspect first folds a rope in half and puts it on the deadbolt and then pulls it through the hole to the outside, and then he goes out and tightens the door, walks to the side and pulls the rope deadbolt to easily put the deadbolt on, and finally pulls off the rope and a secret room is successfully completed."

In order to make everyone more clear, the tension also deliberately took everyone to the roof of the building and conducted an experiment in front of everyone.

"So how did he get downstairs?" The forensic doctor was also interested.

Tang Tao walked to the back of the building, pointed to a Nanzhu two meters away, and said, "Yueyang is you." ”

"Okay."

Yue Yang took a few steps back, accelerated and rushed forward, took two steps, jumped into his arms, hugged Nanzhu, and easily slid to the bottom of the building.

The series of methods used by the serious crime team to solve the case amazed the people present, and a closed room murder case was easily solved in front of them.

From reasoning to criminal process deduction, it is impeccable, especially when the secret room has just been cracked, which is an eye-opener for everyone.

Even the arrogant Shao Guobin surrounded Tang Tao.

"Can you reconstruct the crime?" Shao Guobin asked Tang Tao from the bottom of his heart.

Tang Tao led everyone to the door.

"At three o'clock in the morning last night, the murderer came to Zhou Qin's house, he found a pair of shoes outside the door, so he changed the shoes and knocked on Zhou Qin's door, he came prepared with a pair of gloves, this person was very familiar with Zhou Qin, and easily entered Zhou Qin's house, after entering the house, the two people clashed, the murderer was extremely fierce, grabbed Zhou Qin's face and hit the wall fiercely, his force was great, this blow caused Zhou Qin's skull fracture, and he fell into a coma at that time."

Tang Tao paused and changed his rhetoric again.

He just wanted to teach Zhou Qin a lesson, killing people was not his intention, and he was scared when he found Zhou Qin falling to the ground and convulsing, he ...... He made a distress call to ask what to do, this person may be Ma Jinbo's military advisor, this time it was this person's idea, Zhou Qin's serious injury completely exceeded their expectations, so they decided to kill Zhou Qin to create a suicide illusion, the murderer hung Zhou Xia on the electric fan according to the instructions, and finally fled. ”

"On the basis? On what basis do you say that he was commanded? Shao Guobin asked.

"That rope is the basis, if all this is done by the murderer, then he must have been very calm at the time, he thought about everything, he would never make such a low-level mistake, at that time he was completely passive according to the arrangement of the people behind the scenes, he was particularly flustered, like a puppet, these two people are probably also the murderers of Ma Jinlong, Ma Jinlong's case is also forged into an accident, the person who manipulated behind the scenes is definitely a master of crime, with a cool mind, careful thinking, Especially the trick of murder in a closed room is something that ordinary people will never think of, he likes to read books or watch detective TV series, and has learned a lot of criminal knowledge, he knows very well that the injury on Zhou Xia's head will sooner or later be a gang, which is just to delay the speed of the police to solve the case and buy time for the next step of the escape. ”

Tang Tao's voice flashed in his mind, could it be that the person hiding behind the curtain was her?

"Isn't this murderer Ma Jinbo?" After Zhang Zhang finished speaking, he hurriedly explained: "Last night Zhou Qin was in trouble, Yue Yang rescued her, when we asked about Ma Jinlong, she told us that Ma Jinlong was killed, if Ma Jinbo spied on us, then he must have heard our conversation, so before fleeing last night, he found Zhou Qin and wanted to warn Zhou Qin, but he didn't expect a conflict, which is what happened later, Ma Jinbo has the motive to commit the crime and the time to commit the crime, he and Ma Jinlong are just half-brothers, not brothers, It's entirely possible that he would kill his own big brother. ”

Shao Guobin nodded in admiration.

"Perfect, you guys are really amazing, the search warrant has come down, the next step is to comprehensively search Ma Jinbo's home and travel agency, it's not too early now, why don't you go eat something first?"

Shao Guobin was completely convinced, the professionalism of these people was far from the criminal police team in the supermarket.

"No need, I'm going to do a footprint comparison now to further determine the identity of the suspect." Sophie said.

"Then I'll accompany you."

Sophie was about to say something and found that Tang Tao and Zhang Zhang had left, this guy was really a person with no emotional intelligence, so she just left, she glanced at Shao Guobin and nodded and reluctantly agreed.

The police opened Ma Jinbo's travel agency and home, and also found several travel agency staff, including the front desk attendant, and under her leadership, the police successfully found the camera hidden in the room, confirming Zhang Li's earlier inference.

The front desk explained that it has been several years since the installation of voyeur cameras, which has long been an open secret in Donghua Township, the purpose is to gain insight into the passengers' every move, know in advance where they are going, what their plans are, and then arrange for people to continue to trick them.

It can be said that from the beginning of the traveler into the travel agency they have become a lamb to be slaughtered, tour guides, drivers, are their people, peers will also exchange information with each other, if a traveler in the first is too expensive to run to the second, then the second will immediately know his information, he will also be slaughtered, the money earned in the middle will be returned to the first one according to a certain percentage.

If the passengers report a warning, they will also summon the horse boy to abuse and harass or even beat him, because it is just an ordinary police case, even if it is called to the police, he will be detained for a few days, and it will have no effect on them.

That night, Sophie compared and identified all the footprints, and she found that the murderer's left foot was an outer figure, which was obviously different from Zhou Qin's footprints.

From the distribution of footprints, it can be seen that he and Zhou Qin had a fight in the living room, and the footprints in this place are the most and the most chaotic, and the footprints in the bedroom are concentrated under the electric fan.

After that, the murderer went to the roof of the building, and the footprints on the roof showed that he did go to the side, and Tang Tao's inference was verified, and the murderer did use a rope to lock the door and create a secret room.

Sophie is convinced that Ma Jinbo is the suspect after comparing Ma Jinbo's footprints!
