Returning to the attic, at this moment, Gu Chen had already completed the photographing and forensics work on the subtle clues on the wall.

The latecomer, Officer Wang, was a little confused, so he hurriedly asked Gu Chen, "Gu Chen, what are you doing photographing these tiny holes in the wall?"

"Senior Brother Wang, go up and check it to see if this little hole was drilled before, or if it was drilled recently?"

Gu Chen didn't explain it directly, but asked Officer Wang to find the answer by himself.

Officer Wang frowned, turned on the bright flashlight in his hand, and shone it on these tiny holes.

Then I touched it lightly with my finger, and soon found that there were some fine sand and gravel on the holes.

With a gentle blow with his mouth, the fine sand and gravel in the original small hole quickly flew out of the aperture.

Officer Wang fanned the dust with his right hand, and then confirmed: "These small holes are all newly opened, and the time should not be long." ”

After thinking about it, Officer Wang glanced at Gu Chen and asked, "What are you asking me for? Could it be that this is left by the murderer?"

"That's right, these holes were left by the murderer to strangle Gao Jian's mechanism. Gu Chen said.

Officer Wang frowned, looked at Lu Weiwei and Zhang Xiaomei beside him, and still didn't seem to understand.

The small holes in the wall can even strangle the tall building?

Of course, Officer Wang will not delve into this problem, with Gu Chen at the scene, he is more willing to listen to Gu Chen's explanation, so he asked: "But how did the murderer do it?"

At this moment, Chen Kui, the owner of the haunted house, Zhang Xiaoyu, a fat woman, and the bald Han Fei also came to the attic.

Everyone stared at Gu Chen, wanting to hear Gu Chen's explanation.

Gu Chen walked to the wooden window and opened it.

Suddenly, the sun shone in from outside, and everyone couldn't help but cover their eyes.

"Everyone has seen the marks on the wooden window, right?" Gu Chen said, pointing to the trail mark.

Everyone nodded.

Gu Chen said again: "Gao Jian's death is preliminarily inferred to be suffocation, and combined with the strangulation marks on Gao Jian's neck, it can be seen that he was strangled to death by the rope around his neck. ”

"But this involves a question, what kind of person can make a strong Gao Jian powerless to resist?"

Everyone was stunned, looked at each other, and did not respond.

Gu Chen replied directly: "No one can do the answer. ”

"Officer Gu, since no one can do it, could it be that Gao Jian exhausted himself to death?"

I felt that listening to Gu Chen's words, I felt that Gao Jian's death was becoming more and more strange.

Gu Chen shook his head and said indifferently: "It is difficult to do this alone, of course, the first possibility is involved here, that is, a group crime, several people go up together, and jointly strangle Gao Jian to death." ”

"No way. Chen Kui immediately vetoed Gu Chen's statement, and also argued on the basis of reason: "We people have always had a good relationship with Gao Jian, how could we do such a thing collectively?"

"That's right, even if we want to kill Gao Jian, don't we have to make it so complicated? Why do you have to strangle him to death, and then call the police, isn't this a self-defeating trap?" The bald Han Fei also vigorously denied it.

Zhang Xiaomei raised her hand and said weakly: "It's me who called the police, it's impossible for me to throw myself into the net, right?"

"Don't worry. Seeing that everyone already had a rebuttal mood, Gu Chen directly pressed his hand and continued to explain: "I'm talking about the first possibility, but judging from the current existing conditions, it doesn't seem to be valid. ”

Pointing to the people in the haunted house in front of him, Gu Chen said again: "Just like you just said, if you are committing the crime collectively, there is no need to make it so complicated. ”

"You will quietly dispose of Gao Jian's body, and then choose a long time to call the police, rather than choosing to call the police as soon as Gao Jian disappears. ”

"You should all know that the shorter the time of the case, the more beneficial it is to the investigation of the case, and I don't think you are stupid enough not to know this, so it can be seen that most of you don't know, and you don't know where Gao Jian is. ”

"yes, we really don't. Zhang Xiaomei also tried her best to defend herself, and said: "And if we commit the crime collectively, then there is no need to do such a thing as stealing beams and changing pillars in order to hide Gao Jian's body." ”

"Gu Chen. Officer Wang looked at everyone's frightened reactions and said thoughtfully: "Since the first case is not true, what about the second method?"

"The second method is to use the field, put a rope around Gao Jian's neck, and then strangle him to death, which involves a problem of organs. ”

"External force?" Officer Wang glanced at the marks on the wooden window frame, and suddenly asked, "You mean that the murderer used external forces to strangle Gao Jian to death from outside the window?"

Gu Chen nodded: "That's right, that's it." ”

"Then how can the murderer be sure, he must be able to wrap Gao Jian's neck, is it a little difficult to control Gao Jian's movements in the attic outside the window?"

The fat woman Zhang Xiaoyu also raised her own questions.

Of course, Gu Chen had thought about this before, and he couldn't figure it out, until he found the BB bomb in the passage, the white car outside, and many small holes in the wall, that he was able to support his thoughts.

"Don't worry. Gu Chen looked at the bald Han Fei with an indifferent face and said, "Mr. Han Fei, can you help me get a rope as thick as the one around Gao Jian's neck?"

"That's fine, there should be one in the haunted house. The bald Han Fei affirmed.

Gu Chen nodded slightly, and continued: "In addition, you can help me get some long thumbtacks, as well as thin ropes, the kind that threads the needle, it doesn't need to be too thick, but it must be strong enough, can you find these?"

"Uh......"

The bald Han Fei was silent for a few seconds, but still nodded and said, "It should be possible to find it." ”

"Okay, you help me find these items now, and I'll restore it to you, how the murderer committed the crime. Gu Chen said.

Hearing Gu Chen's words, the haunted house owner Chen Kui, Zhang Xiaomei and Zhang Xiaoyu, as well as the bald Han Fei, all looked at each other and whispered.

It seemed as if Gu Chen already knew the whole process.

However, since Gu Chen asked, everyone could only do as they were told.

The fat woman Zhang Xiaoyu said directly: "Okay, I know where these things are, I'll go with Han Fei to get them." ”

"Go and come back. Gu Chen turned around and looked straight out the window.

What I have now is time.

It didn't take long for Han Fei and Zhang Xiaoyu to take all the items that Gu Chen needed to the attic and throw them on the floor.

"Officer Gu, all the things you want have been prepared, do you think these things are okay?" Han Fei asked.

Gu Chen turned around and glanced at the items on the ground, then nodded in satisfaction.

Subsequently, Gu Chen tied the thicker rope into a slipknot buckle.

Using a long pushpin, it is fixed on several original small holes, and the slipknot buckle rope is wrapped with a thin wire to form a suspended shape based on the pushpin.

In this way, the rope that was suspended in the air was hung by Gu Chen on the periphery of the small window under the exquisite arrangement.

The layout is not visible from the inside of the attic.

"Now look at it. Gu Chen gave up a position.

Officer Wang was the first to stick his head out of the window.

Although the window is small, Officer Wang can still fully protrude his upper body out of the window.

Then glancing at the rope slipknot hanging outside the window, Officer Wang couldn't help but retract his neck and asked Gu Chen, "So...... This is the rope trap set by the murderer?"

"Yes. Gu Chen nodded and continued: "Gao Jian, just like Senior Brother Wang just now, stuck his head out of the window, and then was activated by the murderer outside the window, put the rope around his neck accurately, and then strangled him to death in the attic window. ”

"But ......"

Zhang Xiaomei frowned, and couldn't help but say: "But Gao Jian has a lot of strength, even if he is covered with a rope around his head, he can retract it." ”

"That's right. Before Zhang Xiaomei could finish speaking, Zhang Xiaoyu, the fat woman on the side, also hurriedly added: "Even if what you said is right, who can pull the rope and strangle Gao Jian to death?"

Gu Chen smiled and said: "As I said just now, the first possibility is to commit a crime collectively and be operated by several people together, but this possibility is not very likely. ”

"There is also a possibility, that is, with the help of an external force, and this external force is the white car parked in the back of the haunted house. ”

"The white car?"

As soon as they heard Gu Chen's words, everyone shouted in unison, and seemed to suddenly realize.

Gu Chen continued: "I checked the white car in your haunted house, and there are obvious traces of rope binding at the rear tail hook. ”

"I think the murderer used to tie the other end of the rope to the white cart at that time, which played a good role in borrowing. ”

Looking at the four people in front of him with a confused face, Gu Chen said again: "Is the strength of a car enough to strangle the strong Gao Jian?"

The bald Han Fei was stunned for a moment, and then said: "If you say so, it is indeed possible, after all, the pull of the car is much higher than the pull of several adults." ”

"Yes. Gu Chen nodded silently, and then patted the small window of the attic: "And you have also seen that the small window space in the attic is very small, and I asked my colleague Senior Brother Wang to get out just now." ”

With his size, his upper body can barely stick out of the window, but Gao Jian is different. ”

"Gao Jian's entire body skeleton is obviously more than my Senior Brother Wang, if it is Gao Jian, he can only poke his head out of the window, but his body will be completely stuck on the wall. ”

"As you saw just now, Gao Jian will only poke his head out of the window, but his body and hands remain completely in the attic. ”

In this way, as long as the rope slipknot buckle is put around the neck and pulled hard, Gao Jian will be strangled to death at the window in an instant. ”

No matter how strong his strength was and how strong his hands were, in an unguarded situation, coupled with the pull of the white cart, everything was in vain, and he would be strangled to death in an instant. ”

Hearing Gu Chen's explanation, everyone suddenly fell silent.

Such a modus operandi makes everyone listen to the creeps.

Who would have thought that the strong Gao Jian, whose body and hands were left in the attic, while his head was hung outside.

Coupled with the pull of the car, this hanging head killing method is simply terrifying.

Zhang Xiaomei trembled and said, "Gu ...... Officer Gu, can ...... But even if what you say is true, then ...... How can the murderer conclude that Gao Jian will definitely poke his head out?"

"Of course, the murderer is not easy to judge. After Gu Chen glanced at everyone, he said, "But the murderer is very cunning. ”

He first used some means to direct Gao Jian to go to the attic, and the reasons could be various reasons, such as the attic window was not closed. ”

But when Gao Jian came to the attic and was about to close the window, he heard a 'crackling' sound outside the window from time to time. ”

At this time, Gao Jian would be curious, and then, unsuspectingly, he stuck his head out of the window to find out. ”

But at this time, the murderer started the vehicle, a quiet and environmentally friendly new energy electric vehicle, and instantly put the rope slipknot hanging outside the small window on Gao Jian's neck. ”

Coupled with the huge pull of the white car, this strangulation method can instantly dislocate Gao Jian's head, and the knotted buckle of the rope can also suffocate Gao Jian to death in an instant. ”

"This kind of operation is very vicious, and Gao Jian will not escape death no matter what. ”

"Wait a minute. The bald Han Fei was stunned, and then asked again: "Officer Gu, what did you just say about luring Gao Jian to poke his head out, what is that 'crackling' movement?"

"This. Gu Chen lit up the colorful BB in his hand in front of everyone, and continued: "This is the BB bullet I found in the iron plate trench under the blood puppet rope net. ”

The murderer used this kind of thing to constantly enlarge the outer edge of the window, resulting in some strange movements to attract Gao Jian to poke his head out. ”

"And these BB bullets, obviously the murderer shot directly into the window during the ejection process, because there is no guardrail at the edge of the attic, so these BB bullets are directly hung along the edge of the attic in the iron plate trench under the blood puppet rope net. ”

"I see. Lu Weiwei suddenly realized, and then said in surprise: "No wonder Senior Brother Gu was looking for a long time below just now, but how did you know that these BB bullets would be scattered under the rope net of the blood puppet props?"

"Good question, this involves a question of the time of the crime. Gu Chen saw Lu Weiwei say this question, so he directly extended it.

"Because after we experienced the VR scene at that time, under the leadership of Zhang Xiaomei, we were ready to return to the Seremban Branch. ”

"When I walked under the Blood Muppet prop, I clearly felt that there was a bead-shaped object in the middle of the ground, and there was more than one, which was actually these BB bombs. ”

Glancing at the people in the Hanshan Haunted House, Gu Chen stretched out his right index finger and said, "But pay attention to one thing, these BB bombs were not available when we first came to the Hanshan Haunted House and passed through this small door." ”

"Because we were very careful when we came in, and the ground was swept by flashlights, I can conclude that these BB bullets didn't exist when we entered this little door. ”

"But when I returned, because I already knew the layout of the scene, when I left this small door, everyone didn't pay too much attention to it, but at this time, there were a few BB bombs in the middle of the road. ”

"This can only show that Gao Jian was hanged in the attic when we left last night, and this just verifies my examination of Gao Jian's body, that is, the time of Gao Jian's death, is indeed the time when we left. ”

"I ...... OMG. Zhang Xiaomei wiped the beads of sweat from the corners of her forehead, and couldn't help but say, "This ...... This is too terrifying, isn't it?Gao Jian was still in the Pansi Cave Restaurant before, how could he ...... so quickly?"

Glancing at Gu Chen, Zhang Xiaomei, the woman in red, hurriedly asked again: "Then Officer Gu, who do you think the murderer is?"

Gu Chen glanced at Zhang Xiaomei, who was overly nervous, patted her on the shoulder and comforted: "Of course, it's definitely not you, because you have been waiting with Senior Brother Wang at the Pansidong Restaurant for me and Senior Sister Lu to experience VR technology." ”

Looking at the bald head Han Fei beside him, Gu Chen said again: "Of course, it can't be you Han Fei, because when we were experiencing VR technology, you followed us, so it wasn't you." ”

"It's not me and it's not Han Fei, is it ......" Zhang Xiaomei seemed to be a little conscious, and her eyes involuntarily looked at the boss Chen Kui and her sister Zhang Xiaoyu: "It's difficult...... Is it you?"

"Don't talk nonsense. Zhang Xiaoyu was also frightened, and quickly explained: "Haven't I been with you all the time?"

"But when we left later, only Han Fei was with us, and Zhang Xiaomei and Lao Wang were waiting for us at the Pansidong Restaurant, you were indeed not there at the time. Lu Weiwei also had something to say and sorted out the situation with Zhang Xiaoyu.

Zhang Xiaoyu hurriedly explained: "But I saw Gao Jian answer a phone call and leave, and it took a long time for me to walk away, I just wanted to go to the toilet." ”

Glancing at Gu Chen, Zhang Xiaoyu hurriedly explained to Gu Chen: "Officer Gu, I left long after Gao Jian left, so I went to the toilet, and Zhang Xiaomei can testify to this." ”

"Yes, Officer Wang and I can testify. Seeing that her sister was in a hurry, Zhang Xiaomei also hurriedly explained to Gu Chen.

Zhang Xiaoyu saw Gu Chen's indifferent face, so he said again: "And even if what you said is true, then there must be enough time to prepare, how can I go to the toilet in such a short time?"

"When you left, I just came out of the toilet, and when I turned around, I saw Zhang Xiaomei greeting you at the door and saying goodbye. ”

Gu Chen glanced at Zhang Xiaomei, the woman in red, and asked, "Is that so?"

"That's right. Zhang Xiaomei nodded fiercely and explained: "I just saw Zhang Xiaoyu coming out of the toilet door after sending you to the car, and then I also went to the toilet, there was obviously some smell in the toilet, I can be sure that Zhang Xiaoyu did go to the toilet at that time." ”

"That's right. Gu Chen was very grateful to Zhang Xiaomei and Zhang Xiaoyu for their self-explanation.

In this way, Zhang Xiaoyu's suspicion can basically be ruled out.

And the last suspect who was not at the scene was only Chen Kui, the owner of the Hanshan Haunted House.

Gu Chen turned to face Chen Kui and couldn't help but say, "If that's the case, eliminate all the impossibilities, then the murderer is your Boss Chen." ”

When the words fell, everyone couldn't help but be surprised, and their eyes turned to Chen Kui.

......
