I am a super cop

Chapter 762 Cutting Experiment 【Seeking Monthly Pass】

Han Feng was dumbfounded, and couldn't help complaining: "Then this is going to be a big trouble, so it's entirely possible that Zheng Peiwen was wearing those bloody jeans to work."

Walking to Gu Chen's side, he took the bloody jeans from Gu Chen's side. Han Feng also observed carefully before saying, "My head hurts, what kind of blood is this?"

"He said it was Yuejing's blood from his girlfriend." Officer Wang said.

"Yuejing blood?" Han Feng was stunned for a moment, and after turning the jeans panel left and right again, he said, "Then, this is a pair of jeans worn by women? But why doesn't it look like it?"

"Because it's a men's style, but my girlfriend's height and shape are similar to mine, and she usually wears it to work, so there's nothing to say."

Zheng Peiwen seemed to lose his previous nervousness after talking with the police.

He also became more calm when discussing the situation with the police.

Gu Chen saw this, but didn't say it out, but it didn't seem like he made a premature judgment.

Indeed, Gu Chen knew very well, even if Zheng Peiwen was wearing these bloody jeans, so what?Meng Dao's body was lying there, and his body was riddled with holes.

But even for the most cautious person, it is impossible for you to only splatter blood on the jeans on the lower body when using tools, while there is no sign of blood on the overalls on the upper body.

It doesn't make sense at all.

Because Gu Chen was aware of this, he came to the bloody tool again and began to check the tools on the spot.

On the other side, Han Feng and Police Officer Wang were still arguing over the bloody jeans.

Although the two had doubts, everyone was powerless to refute the results given by Zheng Peiwen.

"Who can connect the phone for me?" Gu Chen looked up at everyone.

"I can." A bald man in a vest stood up and said, "I can take this for you."

"Very good, I need electricity now, start these tools and see how the situation is on site." Gu Chen said.

The bald man hesitated for a moment, then asked Gu Chen weakly: "Comrade policeman, you want to simulate an experiment of cutting up corpses on the spot, right?"

Seeing that Gu Chen was staring at him, it seemed that the answer was yes, the bald man was taken aback for a moment, and said a little frightened: "But Comrade Police, it's impossible for you to conduct experiments on Director Meng again, right?"

"Hehe." Feeling that the bald man really has a strong figure and a simple mind, Gu Chen didn't know how to communicate with him, so he could only smile and said, "Since you are in charge of logistics, you should know that there are many dummies in the crew props."

"You take out the dummy props, and then bring me a few packs of artificial plasma, and you will know how to operate it."

"Oh, why am I so stupid." Hearing Gu Chen's words, the bald man also slapped his bald head: "Look at me, I always think about problems without going through my head."

"Then you still have the nerve to be bald?" The chief director Yan Wenqiang couldn't stand it anymore, and directed a staff member beside him to say, "Xiao Zhao, go find a dummy prop in the logistics warehouse, and listen to the comrades in the police. I also brought a few packs of artificial plasma for filming."

"No problem director." The staff member named Xiao Zhao nodded, hurried back to the commercial vehicle, and drove away from the scene.

Only then did Yan Wenqiang glance at the bald man, and said with some distaste: "Then why are you still here? Get the phone over quickly."

"Oh." The bald-headed man was always slow to respond, and then he said to the other four workers, "Four of you come with me and get the electricity."

Everyone is still busy at the scene...

However, at this time, Gu Chen had returned to Dao Meng's body.

Looking at the mobile phone that Lu Weiwei handed over, Gu Chen opened the photo album and looked at the photos of the corpse that Lu Weiwei had just taken.

There are more than 30 photos of Director Meng's corpse, and Lu Weiwei took almost every detail.

Gu Chen is satisfied with this...

While looking at the photos, Gu Chen was also asking himself.

"Although during the autopsy, I have already figured out what happened at that time."

"The victim, Dao Meng, had some deep cuts made by a circular saw, as well as those two holes."

Looking at Dao Meng's body in front of him, Gu Chen couldn't help frowning slightly: "One of the holes is on the neck, and the other is on the back."

"Obviously the guy was trying to dismember the body. He was trying to cut it with a circular saw."

"But because he cut too low, the shirt and multi-purpose vest of the deceased Meng Dao got entangled in the circular saw, so he couldn't continue cutting."

Thinking of this, Gu Chen slowly squatted down, continued to look at Meng Dao's corpse in front of him, and compared the pictures with the real thing based on the photo album taken by Lu Weiwei's mobile phone.

"The killer couldn't continue cutting, so he tried to unhook the circular saw from his clothing, then walked over and picked up a power tool that he could find, which was a power drill with a 1-inch bit."

Looking back at the electric drill on the ground, Gu Chen nodded slightly: "That's right, he first used the electric drill to drill into the neck of the deceased Meng Dao, and when the drill bit entered half of the deceased Meng Dao's neck, he set the electric drill to reverse Rotate it and pull it out."

"Then he tried to drill a second hole in the back of the deceased Meng Dao, but he forgot that the electric drill was in the reverse rotation state, so it was not successful."

Thinking of this, Gu Chen couldn't help snapping his fingers, which stunned Lu Weiwei on the side.

Lu Weiwei asked Gu Chen weakly: "Junior Brother Gu, did you think of something?"

"Yes." Gu Chen nodded slightly, still obsessed with his judgment of the mobile phone pictures and the dead bodies at the scene.

"Because the murderer forgot that the drill was in reverse rotation, he didn't succeed."

"Therefore, there is an electric drill mark in the middle of the victim Meng Dao's back, and I can also find that the deceased Meng Dao's spine has trauma caused by the heavy blow."

Use your own judgment, and photos from your phone.

Gu Chen held the mobile phone in his left hand and swiped the screen with one hand, while his right hand continued to examine Meng Dao's body.

"That's right, the heavy blow wound was indeed caused by the hammer, and when I checked the scene, I did find a 20-pound hammer, and that's how the wound came about."

"But these can be easily deduced, but there is still a problem, that is, if the murderer is really Zheng Peiwen, how did he manage to leave blood on the jeans, but not on the overalls?"

"His overalls are very clean, but how can he take off the only piece of clothing in this kind of weather, which is very cold at night?"

"But since the murderer used a high-speed rotating circular saw to cut the body, where did the blood go? Why isn't the suspect Zheng Peiwen covered in blood?"

Thinking of this, Gu Chen suddenly remembered what he had seen in the forensic manual about the identification of bloodstains.

Indeed, it can be known from physics knowledge that the direction of blood stains on jeans is indeed not simple.

But if Zheng Peiwen is proficient in using tools, will the blood spattering in this area be reduced?

Gu Chen suddenly remembered some books about the construction industry that he had read in the city library.

However, due to the partiality, Gu Chen only had a look at it, and the impression was not very deep.

Therefore, Gu Chen suddenly closed his eyes, activated his specialized memory, and deepened and consolidated the once vague knowledge.

In the past ten seconds or so, the previous book knowledge about the construction industry suddenly became clearer in my mind.

"The effect is good." Gu Chen secretly rejoiced in his heart, feeling that the professional level memory, since it has been continuously upgraded, can also start to consolidate the previous knowledge well.

He usually reads a lot, so at critical moments, Gu Chen was able to extract the available conditions from his knowledge base.

"That's right." The corners of Gu Chen's mouth rose slightly: "Some people who have worked in the construction industry, many people will remove the spring of the protective ring when using a circular saw."

Gu Chen frowned slightly, and continued to extract this knowledge into the pages of his mind: "When people use a circular saw to cut something, the protective ring will go up so that the circular saw can cut."

"But once the circular saw is removed from the material being cut, the guard covers the teeth to prevent people from accidentally cutting themselves."

"And this protective ring ... can also play a role in guiding the direction of the splash of debris falling from the material being cut and throwing it out."

"That's why, the suspect Zheng Peiwen's body was not splashed with blood, but the blood will splash out along the protective circle, that's why."

Seeing myself have a lot of photos taken of the crime scene, including the blood splatter, and the tools.

Gu Chen seems to be looking forward to the truth more and more...

But even if you don't do this experiment yourself, you can still take this bloody pair of jeans to the technical department of the Municipal Bureau for testing.

As long as the test results prove that the blood came from the deceased Meng Dao, then Zheng Peiwen has nothing to say.

Girlfriend's Yuejing blood?

Gu Chenxin said, I believe you are a ghost.

Although Gu Chen was very sure that the blood on that pair of jeans belonged to Meng Dao, but Gu Chen didn't want to wait.

Because the suspect Zheng Peiwen also said, why is there no blood on his upper body?

Since he proposed it himself, Gu Chen feels that it is necessary to conduct a simulation experiment on the spot, and this step is absolutely necessary.

In order to make Zheng Peiwen give up.

Zheng Peiwen, who was in front of him, seemed to have seen Gu Chen's thoughts, his whole heart was fluctuating, but he showed a calm face.

Perhaps because Zheng Peiwen knew the characteristics of operating this tool, he was a little relieved.

At this moment, the staff who went to the logistics warehouse to pick up props and artificial plasma for filming had also driven back to the scene.

As soon as the vehicle stopped steadily, several other crew members immediately stepped forward to help move the goods.

"Comrade policeman, I have brought what you want, where can I put it?" asked the staff who picked up the props.

"Just... put it here." After looking around for a week, Gu Chen pointed to Meng Dao's corpse not far away.

"Okay." Several staff members nodded, and put a realistic dummy in front of Gu Chen.

The chief director Yan Wenqiang stepped forward and introduced: "Comrade policeman, this is the most expensive dummy in our crew. It is very realistic in every way, and it should be able to meet your experimental requirements, right?"

Gu Chen simply flipped through it a few times, nodded and said, "Almost."

"Then...that's good." Speaking of this, the chief director Yan Wenqiang took another few bags of artificial plasma used for filming in his hand, and asked Gu Chen: "Where do you put this thing?"

"Fall on the dummy." Gu Chen glanced at Meng Dao's corpse not far away, and said again: "According to Meng Dao's wound, it is possible to fill the place."

"Okay, I'll listen to you." Chief Director Yan Wenqiang also felt awkward.

In the film crew, he always orders people around by himself, especially for young people like Gu Chen, who is called around.

But now, he was being ordered around by a hairy policeman, so he didn't dare to complain.

The main reason is that all the policemen at the scene seem to be listening to this young policeman named "Gu Chen" giving orders.

Based on his own experience in the world, chief director Yan Wenqiang knew that this young man named Gu Chen must not be that simple.

At least from the professional level of on-site handling of the case, they are already very good.

Yan Wenqiang had to admire this.

The so-called professionals do professional things, since Gu Chen is very familiar with on-site operations, of course he has to cooperate 100%.

As long as he can quickly find the real culprit, it will be good for himself and the entire crew.

Otherwise, once the production crew stops working, the huge expenses for that day will be in vain, and the production funds will definitely be exceeded.

Once the investors are not happy, the funds for the subsequent filming of the plot will be cut off, and it will be cut off substantially.

At that time, I will end up with the title of a bad film director, and I will lose face.

Just when the chief director Yan Wenqiang was thinking wildly, several crew members had already poured the artificial plasma used for filming on the dummy with the same part as Director Meng's wound.

At this moment, the bald man also took several other workers to connect the power plug.

The bald man panted, "Comrade police, everything is ready."

"Who would use this kind of tool?" Gu Chen asked those workers.

Several people looked at each other briefly, and a fat worker raised his hand and said, "We all use it."

"Okay, you do it." Gu Chen said.

The fat worker didn't hesitate, but he was a little bit repulsed by the bloody tools.

Gu Chen took out another pair of gloves from the equipment bag and handed them to him: "Put these on."

"Thank you." The fat worker took the glove and put it on in twos and twos, and then asked again: "Are you going to cut this dummy?"

"That's right." Gu Chen pointed at the body of the deceased Meng Dao and said, "You can cut according to the wound on Meng Dao's body."

"Okay... okay." Although he didn't know what Gu Chen was thinking, the fat worker still reluctantly agreed.

Then lift the tool, turn on the power, and turn on the switch.

Suddenly, there was a violent spinning sound.

Everyone around couldn't help but tense up.

The fat worker took a deep breath before cutting towards the dummy covered in artificial plasma.

With the sound of violent friction, the plasma splashed everywhere, and the fat worker was immediately covered in the splashed plasma.

The other spectators were also instantly scattered by the splashed plasma.

Fortunately, Gu Chen had the foresight to take his team away from the scene.

The fat worker hurriedly turned off the switch, turned his head, and said to Gu Chen in frustration: "Comrade policeman, look at my body."

"I know." Gu Chen nodded slightly, and glanced at Zheng Peiwen not far away.

At this time, Zheng Peiwen also smiled lightly, and said to Gu Chen: "Comrade policeman, I have already said that this thing will definitely splash all over with this kind of tool, you still don't believe it."

Speaking of this, Zheng Peiwen still didn't forget to pinch his top and work clothes, and said in a teasing voice: "You always know that I was wronged now, right? I didn't kill Director Meng at all."

"This..." Officer Wang frowned slightly, and said to Gu Chen with some embarrassment: "Gu Chen, you have also seen the experiment, the situation is like this, if the machine is turned on, once the gear is cut, the blood will definitely splatter are everywhere."

"But Zheng Peiwen didn't have any blood on his upper body at all. What's going on? Could it be that the murderer wasn't him at all?"

"Senior Brother Wang." Gu Chen glanced at Police Officer Wang, and said with a light smile, "Don't worry, the experiment has only reached the first stage."

"Phase... the first stage? That's all?" Police Officer Wang couldn't figure out what Gu Chen meant, his head was buzzing.

And Han Feng on the side also asked in a daze: "Gu Chen, do you still have a second stage of this experiment?"

"Yes, of course." Gu Chen's answer was very affirmative, pointing to another tall and thin worker, "You use this tool."

"I...me?" Seeing that the chubby colleague had already "succumbed", Gu Chen picked himself again.

The tall and thin worker instinctively rejected it and said, "It's too dirty to wash all over the body."

"Then let Director Yan help you with the laundry problem, how about it?" Gu Chen glanced at the Chief Director Yan Wenqiang beside him.

What else can Yan Wenqiang say?
I feel that Gu Chen's thoughts are unfathomable, but I don't know what Gu Chen is up to.

Chief Director Yan Wenqiang, who was eager to learn, could only reluctantly nod his head and said: "Okay, our crew will help you with the clothes, go ahead."

"Then... that's fine." The tall and thin worker stepped forward, put on the gloves he took from the fat worker, and was still thinking about it: "I've tried it once, why do you want to experiment? It's meaningful." ?"

The moment he took over the tool, the tall and thin worker was about to turn on the switch, but Gu Chen immediately stopped him and said, "Wait a minute, remove the spring of the circular saw's protective ring for me."

"What... what?" Hearing Gu Chen's words, Zheng Peiwen, who was standing on the side, was suddenly startled, and a thunderbolt flashed in his mind.

Gu Chen noticed this detail, but kept urging without saying a word.

The tall and thin worker was stunned, feeling a little baffled, but he still obeyed: "Okay, do what you say."

Chief director Yan Wenqiang didn't understand, so he hurried to Gu Chen's side and asked, "Comrade policeman, is there any difference between your operation and just now?"

"Of course." Gu Chen glanced at him, and said truthfully: "When people use a circular saw to cut something, the protective ring will go up so that the circular saw can cut."

"But once the circular saw is removed from the material being cut, the guard covers the teeth to prevent people from accidentally cutting themselves."

"And this kind of protection ring can also play a role in guiding the splashing direction of the debris falling from the material being cut and throwing it away..."

"Wait a minute." Hearing Gu Chen's introduction, Yan Wenqiang suddenly seemed to understand something. He quickly glanced at Zheng Peiwen who was not far away, and said with a light smile, "I understand."
