Han Feng was dumbfounded, and the whole person couldn't help complaining: "Then this is a big trouble, in this case, it is entirely possible that Zheng Peiwen is wearing that bloody jeans to work." ”

Walking to Gu Chen's side and taking the bloody jeans from Gu Chen's side, Han Feng also took a closer look before he said, "The skull hurts, what kind of blood is this?"

He said it was his girlfriend's yuejing blood. Officer Wang said.

"Yuejing blood?" Han Feng was stunned, and after looking at the surface of the jeans left and right again, he said, "So, this is a pair of jeans worn by women, why don't you look like it?"

"Because it's a men's model, but my girlfriend is about the same height and body type as me, and she usually wears it to work, so there's nothing to say. ”

Zheng Peiwen seems to have lost his previous nervousness after some exchanges with the police.

When discussing the situation with the police, I also became more relaxed.

Gu Chen saw this in his eyes, but he didn't say it, but it didn't seem like he was judging too early.

Indeed, Gu Chen knew very well that even if Zheng Peiwen was wearing these bloody jeans, what would happen to Director Meng's body lying there, and his body could be described as full of holes.

But even the most cautious person can't use the tools and only spill blood on your lower jeans, while there is no sign of blood on your upper body uniform.

It simply doesn't make sense.

Because Gu Chen knew this, he came to the bloody tool again and began to inspect the tools on the scene.

On the other end, Han Feng and Officer Wang were still arguing around the bloody jeans.

Although the two were skeptical, everyone was powerless to refute the results given by Zheng Peiwen.

"Can anyone help me pick up the dots?" Gu Chen looked up at everyone.

"I can. The bald man in the crew in a vest stood up and said, "I can take this for you." ”

"Good, I need electricity right now, get these tools up and see how things go on the field. Gu Chen said.

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

Seeing Gu Chen staring at him, which seemed to be a positive answer, the bald man was stunned for a moment, and said in a little frightened: "But comrade policeman, it's impossible for you to experiment on Meng Dao again, right?"

"Huh. Feeling that the bald man was really well-developed and simple-minded, Gu Chen didn't know how to communicate with him, so he could only smile lightly and said: "Since you are in charge of logistics, you should know that the crew has a lot of dummy props." ”

"You take out the dummy prop and bring me a few packets of artificial plasma, and you'll know what to do. ”

"Oh, why am I so stupid. When the bald man heard Gu Chen's words, he also slapped his bald head: "Look at me, I always think about problems without thinking." ”

"Then are you embarrassed to be bald?" Yan Wenqiang, the chief director on the side, couldn't stand it anymore, and commanded a staff member next to him: "Xiao Zhao, you go to the logistics warehouse to find a dummy prop to come over, and listen to the police comrades, and bring a few packs of artificial plasma for filming." ”

"No problem director. The staff member who called Xiao Zhao nodded, quickly ran back to the business car, and drove away from the scene.

Yan Wenqiang glanced at the man in front of him, and said with some disgust: "Then what are you still doing here? ”

"Oooh. The bald man was always half a beat slower to react, and then he said to the other four workers: "You four come with me and bring the electricity." ”

Everyone is still busy at the scene......

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

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

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

Gu Chen was satisfied with this......

While scrolling through the photos, Gu Chen was also asking himself.

"Although by the time the autopsy was performed, I had figured out what was really going on. ”

"The victim Meng Dao had some deep incisions caused by circular saws, as well as those two holes. ”

Glancing at Director Meng's corpse in front of him, Gu Chen couldn't help frowning slightly: "One of these holes is located in the neck, while the other is in the back. ”

"Apparently, the guy tried to dismember the body at that time. He tried to cut with a circular saw. ”

However, because he cut too low, the shirt and multi-functional vest of the deceased Meng Dao were wrapped around the circular serrations, so he could not continue cutting. ”

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

Unable to continue cutting, the killer tried to untie the circular saw from his clothes, then walked over and picked up a power tool he could find, which was a drill with a 1-inch drill bit. ”

Looking back at the electric drill on the ground, Gu Chen nodded slightly: "That's right, he first drilled into the neck of the deceased Meng Dao with an electric drill, and when the drill bit entered half of the position of the deceased Meng Dao's pre-part, he set the electric drill to a counter-rotation state and pulled it out." ”

He then tried to drill a second hole in the back of the deceased Meng Dao, but he forgot that the drill was in a reverse rotation state, so he did not succeed. ”

Thinking of this, Gu Chen couldn't help but snap his fingers, which made Lu Weiwei on the side stunned for a moment.

Lu Weiwei asked Gu Chen weakly, "Senior Brother Gu, do you think of something?"

"Yes. Gu Chen nodded slightly, still indulging in his judgment of the mobile phone pictures and the corpse at the scene.

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

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

According to your own judgment, as well as the photos in your phone.

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

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

"But these can be simply deduced, but there is another question, that is, if the murderer is really Zheng Peiwen, how did he do it, only leaving blood stains on his jeans, but not on his work clothes?"

"His overalls are very clean, but it's cold at night, so how can he take off the only piece of clothing he has?"

"But since the murderer once used a high-speed circular saw to cut the body, where did all the blood go? Why is there no blood stains on the suspect Zheng Peiwen's body?"

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

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

But if Zheng Peiwen is proficient in the use of tools, will it reduce the blood spill in this area?

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

But because it was more out of the way, Gu Chen only glanced at it once, and his impression was not very deep.

Therefore, Gu Chen suddenly closed his eyes, opened his specialization-level memory, and deepened and consolidated his memory of those once vague knowledge.

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

"It works well. Gu Chen secretly rejoiced in his heart, feeling that his mastery-level memory, since he was constantly upgraded, he could also start to consolidate his previous knowledge well.

He usually reads a lot of books, so at a critical moment, Gu Chen was able to extract the conditions available to him in his knowledge base.

"That's right. The corners of Gu Chen's mouth rose slightly: "Some people who have been engaged 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 in the page in his mind: "When people use circular saws to cut things, the protective ring will rise up so that the circular saw can cut. ”

"But as soon as the circular saw is removed from the material being cut, the guard ring covers the serrations to prevent people from accidentally cutting and injuring themselves. ”

"And this protective ring ...... It can also be used to direct the direction of the splash of debris falling from the material being cut and throw it out. ”

This is why, the suspect Zheng Peiwen's body was not splashed with blood, but the blood would splash out along the protective ring, which is the reason. ”

Seeing yourself in possession of a large number of photographs taken at the crime scene, including traces of blood splatters, as well as those tools.

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

But even if you don't do this experiment, you can take this bloody jeans and take them 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 was Director Meng's, 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 felt that it was necessary to conduct a simulation experiment on the spot, and this step was completely necessary.

In order to make Zheng Peiwen die.

Zheng Peiwen in front of him also seemed to see Gu Chen's thoughts, and his whole heart was up and down, but he showed an indifferent face.

Perhaps because Zheng Peiwen knows the characteristics of operating this tool, he will be a little relieved.

At this moment, the staff who went to the logistics warehouse to pick up props and artificial plasma for filming have 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, you have already brought what you wanted, where do you put it?" asked the staff member who picked up the props.

"That's it...... Put it here. After Gu Chen looked around for a week, he pointed to Director Meng's corpse not far away.

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

Chief director Yan Wenqiang stepped forward and introduced: "Comrade policeman, this is the most expensive dummy in our crew, it is very realistic in all aspects, it should be able to meet the experimental requirements you need, right?"

Gu Chen briefly looked at it a few times, nodded and said, "Almost." ”

"That'...... That's good. Speaking of this, the chief director Yan Wenqiang took several other packets of artificial plasma for filming in his hand and asked Gu Chen: "Where do I put this thing?"

"Fall on the dummy. Gu Chen glanced at Director Meng's corpse not far away, and said, "According to Director Meng's wound location, it is possible to fill the position." ”

"Okay, listen to you. Chief director Yan Wenqiang also felt awkward.

In the crew, he has always called people by himself, especially young people like Gu Chen, who are calling and drinking.

But now, he was called around by a hairy policeman, and he didn't dare to complain.

Mainly because all the police officers at the scene seemed to be listening to the young policeman named "Gu Chen".

With his own experience in the rivers and lakes, the chief director Yan Wenqiang knew that this young man named Gu Chen was definitely not so simple.

At least from the professionalism of handling cases on the spot, people are already very powerful.

Yan Wenqiang had to admire this.

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

As long as you can find the real culprit quickly, it will be a good thing for yourself and the entire crew.

Otherwise, as soon as the crew stops working, the huge expenses of that day will be equivalent to waste, and the production funds will definitely be exceeded.

Once the investor is unhappy, the funds for the filming of the later plot will be cut, and it will be cut by a large margin.

When the time comes, he will end up with the name of a bad movie director, and he can't hang his face.

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

At this moment, the bald man also took several other workers and connected the power plug.

The bald man panted and said, "Comrade policeman, everything is ready." ”

"Who would use this tool?" Gu Chen asked the workers.

Several people looked at each other for a short time, and a chubby worker raised his hand and said, "We will all use it." ”

"Okay, you do it. Gu Chen said.

The chubby worker didn't hesitate, but was a little repulsed by the bloody tool.

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

"Thank you. The chubby worker took the glove, put it on his hand three or two times, and then asked, "Are you going to cut this dummy?"

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

"Good...... All right. Although I don't know what Gu Chen thinks, the chubby worker is still reluctant to do it.

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

Suddenly, a violent spinning sound sounded.

Everyone around couldn't help but get nervous.

The chubby worker took a deep breath before cutting through the dummy stained with artificial plasma.

With a violent friction sound, the plasma suddenly splashed everywhere, and the fat worker's body was suddenly covered with the splattered plasma.

The rest of the crowd who watched the excitement were also scattered in all directions by the splattered plasma in an instant.

Fortunately, Gu Chen had the foresight to take his team away from the scene a long time ago.

The chubby worker hurriedly turned off the switch, turned his head, and said to Gu Chen with some frustration: "Comrade policeman, look at me." ”

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

At this time, Zheng Peiwen also smiled faintly and asked Gu Chen: "Comrade policeman, I said it, this thing will definitely splash all over your body with this kind of tool, you still don't believe it." ”

Speaking of this, Zheng Peiwen didn't forget to pick up his shirt and overalls, and said in a mocking tone: "You always know that I was wronged now, right? Director Meng was not killed by me at all." ”

"This ......" Officer Wang frowned slightly, and said with some embarrassment to Gu Chen: "Gu Chen, you have also seen the experiment, this is the situation, if the machine is opened, once the gears are cut, the blood will definitely be splashed everywhere." ”

"But Zheng Peiwen doesn't have any blood stains on his upper body at all, what's going on? Could it be that the murderer is not him at all?"

"Senior Brother Wang. Gu Chen glanced at Officer Wang, and said with a light smile: "Don't worry, the experiment is only in the first stage." ”

"...... The first stage?is it?" Officer Wang couldn't figure out what Gu Chen meant, and his whole head was buzzing.

And Han Feng on the side was also confused and asked, "Gu Chen, is there a second stage of your experiment?"

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

"I ...... Me?" Seeing that the chubby colleague just now had already "hung up the lottery", Gu Chen picked himself again.

The tall and thin worker instinctively rejected: "This thing is too dirty, and it is difficult to wash." ”

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

What else can Yan Wenqiang say?

I felt that Gu Chen's mind was unfathomable, but I didn't know what Gu Chen was doing.

Yan Wenqiang, the chief director who was eager to learn, could only reluctantly nod and said: "Okay, our crew will help you deal with the clothes, you can go on." ”

"That'...... All right. The tall and thin worker stepped forward, put on the gloves he had taken from the fat worker, and his mouth was still broken: "I've already tried it once, why do you still try it? Does it make sense?"

The moment he took over the tool, the tall and thin worker just wanted to start the switch, and immediately stopped Gu Chen and said, "Wait a minute, you remove the spring of the circular saw protective ring for me." ”

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

Gu Chen noticed this detail, but he didn't speak, and continued to urge.

The tall and thin worker was stunned and felt a little inexplicable, but he still did as he was told: "Okay, you can do whatever you say." ”

Chief Director Yan Wenqiang didn't understand, so he hurriedly walked 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 circular saws to cut things, the protective ring will rise up so that the circular saw can cut." ”

"But as soon as the circular saw is removed from the material being cut, the guard ring covers the serrations to prevent people from accidentally cutting and injuring 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......

"Wait a minute. Hearing Gu Chen's introduction, Yan Wenqiang suddenly thought about what he understood, he quickly glanced at Zheng Peiwen not far away, and said with a light smile: "I understand." ”

......
