Gu Chen took out a strong flashlight and shined it twice around the cement board. He pointed at the gap and said, "There are obvious signs of movement in the gap between the cement board. How come you didn't notice it?"
"What? Are there any signs of movement?" After hearing Gu Chen's words, Ding Liang became anxious and quickly lowered his head to observe.
But even if he observed carefully, it was not as exaggerated as Gu Chen said. He immediately asked Gu Chen: "How did you see it?"
"The dust covering the cement board has obvious signs of friction," Gu Chen said.
"Then I was sitting here just now. Could it be that there were traces of friction on my butt?" Ding Liang also had something to say about him sitting here to rest just now.
But Gu Chen shook his head and denied it, waving a mark of friction and saying: "Your butt cannot cover the entire cement board, like the gaps against the wall, these are all blind spots. With the area of your butt, there is no friction at all."
Not in a blind spot.”
"puff!"
Listening to Gu Chen discussing the area of buttocks with Ding Liang, Lu Weiwei and several others couldn't help but laugh.
Ding Liang was a little embarrassed, scratched the back of his head, and said with a sneer: "So, the thing has been hidden under my butt?"
"Is that so? It will be clear after you dig it out and take a look." Huang Zunlong asked Ding Liang to step aside, and he took the initiative to walk forward and clasp the gaps on both sides of the cement board with his hands.
I originally thought it was a heavyweight, but with just a slight mention, the cement board was pulled out.
A travel bag wrapped in a large plastic bag was placed quietly in the middle.
When everyone saw this, they were overjoyed.
Lu Weiwei was also very excited and said: "After searching for a long time, it turns out that this travel bag is here, and Ding Liang is sitting underneath it. It's really dark under the lamp."
"How did I know this thing was here?" Ding Liang was a little dissatisfied and asked Gu Chen directly: "By the way, Gu Chen, how are you sure that this thing is where I rest?"
"Let's judge based on intuition." Gu Chen walked to the cement slab and pointed to the arc-shaped passages on the left and right sides, explaining:
"If a normal person hides something, he certainly doesn't want passers-by to see it, right?"
"But I walked back and forth in this curved alley three times, and found that you are the only one in the dead end of the alley."
"Because things are buried here, the alley exits on the left and right sides are invisible to pedestrians."
"And it's very weird. As long as you move a meter or two to your left and right, you may be spotted by pedestrians at the intersection on both sides of the alley. Don't you think it's magical?"
"So that's it?" Thinking that Gu Chen's judgment did make some sense, Ding Liang immediately said in admiration: "Fortunately, it was you, Gu Chen, who took the initiative, otherwise I don't know how long I would have been busy tonight?"
"It's obviously hiding under my butt, and I didn't know it. It's really stupid."
"It's a good thing to be self-aware. It means you still have room for further study. Give it a try."
After Lu Weiwei finished speaking, she had already put on her white gloves and pushed Ding Liang and others aside.
He carefully picked up the large plastic bag, held it in his hand and blew away the dust.
Gu Chen also put on white gloves at this moment. With Lu Weiwei's cooperation, he carefully untied the plastic bag and then unzipped the travel bag.
Holding up her hands, Lu Weiwei quickly asked: "Junior Brother Gu, what did you see? Is it that drone?"
"That's right." Gu Chen took out a drone from his travel bag.
Ding Liang quickly shined a strong flashlight over to give Gu Chen some light.
Under the bright light, Gu Chen used his master's observation skills to carefully observe the structure of the drone.
The host was intact and Gu Chen gently handed it to Lu Weiwei.
Then I continued to search inside the travel bag, but no trace of the blade was found.
Gu Chen was suddenly startled and murmured: "This drone lacks flight blades, only the main engine."
"It must be that Zhang Wenkai threw away the flying blade with the blade after committing the crime." Lu Weiwei knew Zhang Wenkai's character very well.
This guy is very cunning. After committing the crime, he will definitely throw away the blade and separate it from the drone. It is normal that he cannot find it.
Gu Chen nodded silently, and then took the drone from Lu Weiwei's hand again to observe.
Through the illumination of the light, Gu Chen discovered that the drone had several scratches on its body.
But when I looked carefully, there were traces left, which made my heart skip a beat.
But after a moment, Gu Chen's hanging heart suddenly relaxed again, and the corners of his mouth gradually raised an upward arc.
Lu Weiwei noticed the change in Gu Chen's expression and hurriedly asked Gu Chen: "Junior Brother Gu, have you discovered something?"
"That's right." Gu Chen measured the inclination of the fuselage and showed it in front of Lu Weiwei. He pointed at a gap and said, "This drone may have been stained with the blood of Wang Baocheng and He Jun."
"After all, the high-speed rotation and sharp blade will cut the opponent's neck artery, and the blood will definitely splash onto the body."
"But Zhang Wenkai will definitely wipe the blood stains." Ding Liang said.
Gu Chen continued to nod: "What you said is correct. It is certain that you can wipe off the blood stains, but you may not be able to clean them in some areas, such as this and this."
Gu Chen randomly pointed at several gaps.
Everyone gathered together, used the light to cover, and took a closer look, and found several traces of blood.
When Lu Weiwei saw this, she was also overjoyed and said: "Great, this Zhang Wenkai is still careless. He probably can't wipe these gaps. He just wiped away the blood stains on the surface of the drone."
"Then send it to the Technical Section of the Municipal Bureau quickly and let Gao Chuanfeng extract the blood to see if it belongs to the deceased Wang Baocheng and He Jun?" Huang Zunlong on the side was also anxious at this moment.
It felt like I had made such a significant discovery, and I was no longer tired, so I just wanted to get the results out as soon as possible.
Gu Chen smiled faintly and said slowly: "Even without testing, I know that the blood stains must be from Wang Baocheng and He Jun, but for the sake of going through the procedures, I'd better send them over."
"Leave this to us." Ding Liang felt that he had been working here for a long time in vain, and he felt embarrassed.
This chapter is not over yet, please click on the next page to continue reading! So I quickly took over the task of sending the physical evidence to the Municipal Bureau’s Technical Section for testing.
Lu Weiwei grinned and reminded: "Don't even look at what time it is. If you send me there at this time, Gao Chuanfeng is already having a tryst with Duke Zhou."
"Then wake him up. I know Gao Chuanfeng must be working the night shift in the city bureau's technical department these days."
Ding Liang had had a few words with forensic doctor Gao Chuanfeng when he was maintaining order at the crime scene.
I know that Gao Chuanfeng has been in the testing room during this time.
Lu Weiwei chuckled and continued to remind: "If that's the case, that's best, but you also need to remember that Gao Chuanfeng's destiny is chicken legs."
"Even if he is impatient again, you can just add chicken legs to the takeout and it will be ready."
"Real or false?" Ding Liang, who had rarely interacted with forensic doctor Gao Chuanfeng, was immediately dubious.
But since Lu Weiwei said so, I feel like it’s not a big problem.
Seeing that the time has already reached 3 o'clock in the morning.
Everyone completed a simple handover at the scene, wrapped all the evidence in large evidence bags, numbered it and took photos for evidence collection. Then Ding Liang and Huang Zunlong's team took the evidence to the Municipal Bureau's Technical Section and handed it over to Gao Chuanfeng for processing.
Gu Chen and Lu Weiwei finally breathed a sigh of relief and prepared to return to Furong Branch to continue sleeping.
…
…
The next morning, the sun shone brightly.
Early in the morning, Yuan Shasha had already brought everyone's breakfast.
At this time, Officer Wang had just woken up and saw that Gu Chen and Lu Weiwei had already started working for the day.
After regaining his composure, Officer Wang quickly asked: "By the way, Gu Chen, did you gain anything from going to that alley with Lu Weiwei last night?"
"Of course there is." Gu Chen also grinned when he saw that Officer Wang had woken up.
Before Officer Wang could answer, Lu Weiwei quickly interjected: "We found Zhang Wenkai's travel backpack hidden in the alley last night. Old Wang, guess what's in the travel backpack?
What are they?”
"What things?" Officer Wang raised his head and thought, and said weakly: "Is it a drone?"
"That's right." Lu Weiwei shook her finger and continued to explain: "This is a high-end drone with blood stains. There is blood residue between the gaps of the drone."
"At present, we have asked Ding Liang and Huang Zunlong to take Gao Chuanfeng for testing. It will not take long for the results to be available."
"That would be great if that's the case." After hearing what the two said, Officer Wang was relieved.
But suddenly his expression was blank, and Officer Wang asked again: "Then why did you get up so early? You must have been busy until very late yesterday, right?"
"It's already 3:30 in the morning when I got back," Gu Chen said.
Officer Wang looked in disbelief and stared at Gu Chen and Lu Weiwei carefully.
Lu Weiwei's face looked a little haggard, but Gu Chen's face was radiant, with no trace of fatigue at all.
This made Officer Wang couldn't help but sigh, today's young people are really anti-aging.
After shaking his head, Officer Wang came directly to Gu Chen and found that Gu Chen was already sorting out today's actions.
Some materials are still being drafted, including two simulation dummies.
Officer Wang looked confused and hurriedly asked Gu Chen: "Gu Chen, what are you going to do?"
"I want to expose Zhang Wenkai in public." Gu Chen said.
"Exposed in public?" Officer Wang didn't know why, and asked: "Is it to confirm the fact that he committed murder?"
"Of course." Lu Weiwei came over and said truthfully: "This Zhang Wenkai is quite cunning. If we can't prove that he uses drones to kill people, then this guy will definitely still make excuses."
"So Junior Brother Gu discussed with me and borrowed two dummy models from the Technical Department of the City Bureau, and prepared to demonstrate his modus operandi in front of everyone."
"Then we have to notify Zhang Wenkai to be present." Officer Wang felt that this method was good, but Zhang Wenkai himself must be present.
Yuan Shasha, who was eating breakfast on the side, said: "Senior Brother Wang, you don't have to worry about this. We have asked Liu Shuheng to inform Zhang Wenkai that he must arrive at the Tianlu Yaju construction site early this morning."
"After all, his leg injury is fake, so he should come back early. We can go directly to the Tianlu Yaju construction site to meet them."
"That's great." Officer Wang snapped his fingers excitedly and couldn't help but said, "If that's the case, then everything is ready now, all we need is the east wind."
Looking up at Gu Chen, Officer Wang asked: "As for the issue of drone modification, have you implemented it here?"
"Senior Brother He has been asked to borrow a drone of the same model and then modify it," Gu Chen said.
Officer Wang nodded silently and asked: "What about the Technical Section of the Municipal Bureau? Is there any news?"
Gu Chen shook his head: "I'm currently waiting for their test results. If the results come out as soon as possible, I will ask them to send me a copy of the test report via mobile phone."
"And Ding Liang and Huang Zunlong have also brought the borrowed mannequins to Tianlu Yaju. Senior Brother Wang is just waiting to watch the show."
"Okay, very good." Seeing that he had taken a nap and slept, Gu Chen had already arranged everything in order.
Officer Wang suddenly felt like an idler.
At this moment, Gao Chuanfeng, a forensic doctor with Cao Cao's attributes, suddenly called.
Without saying a word, Gu Chen picked up the mobile phone on the table, opened the answer button, and clicked on speakerphone: "Gao Chuanfeng, what are the results of your investigation?"
"As you wish." Gao Chuanfeng yawned and said feebly: "I have extracted the blood stains from the gaps in the drone."
"After testing and comparison, the blood stains on the wounds of the deceased Wang Baocheng and He Jun were exactly the same."
"It can be said that this drone is stained with the blood of two people."
"That's right." After receiving Gao Chuanfeng's reply, Gu Chen also looked happy and said: "With this result, no matter how Zhang Wenkai tries to quibble, it will be in vain."
This chapter is not over yet, please click on the next page to continue reading! "Gao Chuanfeng, please send me the test report immediately. I will rush to the scene immediately."
The words fell, but there was no movement from the other party.
Gu Chen looked at his colleagues next to him and looked curious, so he asked again: "Gao Chuanfeng, are you listening?"
Gu Chen was a little confused and asked again: "What's wrong with you?"
"That's it." I felt it was necessary to explain it clearly to Gu Chen, so Gao Chuanfeng also took the initiative to explain:
"It was almost 4 o'clock in the morning yesterday. Ding Liang and Huang Zunlong from your Furong branch sent the evidence and called me to wake me up, causing me to help you conduct testing all night."
"Thank you for your hard work, Gao Chuanfeng." Knowing that Gao Chuanfeng was also working hard, Gu Chen quickly expressed his thanks and comfort.
But Gao Chuanfeng said in a sinister tone: "That's what, they said they owed me two chicken legs for takeout. When they borrowed the dummy model, they didn't mention it at all."
"If they don't mention it, you have to remember. After all, I'm working hard too. You, Gu Chen, are responsible for whether you can have a delicious takeout meal with chicken legs at noon and evening today."
"Haha, okay, I will convey it to them." Feeling that it was really interesting to meet Gao Chuanfeng, Gu Chen simply agreed first.
After everyone had a brief exchange, they both hung up the phone.
Gao Chuanfeng, on the other hand, quickly sent his test results in the form of a file.
And since Gu Chen had evidence on his side, there was no need to stay at the police station.
Immediately let everyone pack up and prepare to go to the Tianlu Yaju construction site.
…
…
8 am.
When most workers have arrived at the construction site and are preparing for the day's work.
Gu Chen and others drove the police car over.
Also arriving at the scene early were Ding Liang, Huang Zunlong, and two other auxiliary police officers.
The little bully Liu Shuheng, the accountant Hu Xudong, and Zhang Wenkai were all temporarily called outside.
Everyone placed the dummy at the crime scene and then set up a cordon around it.
Early this morning, Zhang Wenkai clearly felt that he had been controlled by the police.
From the moment he arrived at the outskirts of the Tianlu Yaju construction site, the two auxiliary policemen following Ding Liang and Huang Zunlong had been standing next to Zhang Wenkai.
It wasn't until Gu Chen arrived that Zhang Wenkai didn't know why. He hurriedly asked Gu Chen: "Comrade police, I have already told you that it was a misunderstanding before."
"Even though I'm sorry for my girlfriend, this is an emotional issue between me and my girlfriend after all, so I hope you won't interfere too much."
Pointing at himself, Zhang Wenkai said again: "As for me, I have realized my mistake now. I will definitely change it later. Also, I want to apologize to you for my unreasonable behavior last night. After all, I am not a murderer. You can also use
Don't be so wary of me."
"Zhang Wenkai." Seeing that Zhang Wenkai is still showing a hypocritical face even now.
Gu Chen walked up to him and said angrily: "Do you know the purpose of calling you here today?"
"Purpose?" Zhang Wenkai looked around and saw two dummy models placed at the crime scene. He hesitated and said, "I don't know. Are you investigating the case?"
"In fact, we all know who the murderer is." Lu Weiwei said in anger when she saw Zhang Wenkai's drama.
Zhang Wenkai sneered and replied to Lu Weiwei: "Comrade policewoman, you have to speak responsibly. If you say this, don't you slander me?"
"And I made it very clear in the hospital ward yesterday that the deaths of Wang Baocheng and He Jun had nothing to do with me. I also feel sorry for them both. I..."
"Zhang Wenkai, you are really good at pretending." Officer Wang couldn't stand it any longer. He felt that if he didn't stop Wen Kai from pretending, this guy would really get into trouble.
Zhang Wenkai also snorted and replied: "What should I say? Why should I pretend? You policemen are really interesting. If you can't solve the case yourself, you are always suspicious and look at everyone like a criminal."
Pointing at himself, Zhang Wenkai said confidently: "I, Zhang Wenkai, really don't have time to play house with you. My leg injury is not healed yet. I have to go back to recuperate for a few days."
As soon as he finished speaking, Zhang Wenkai turned around and wanted to leave.
But he was pushed back instantly by two auxiliary police officers.
Taking two steps back, Zhang Wenkai was furious at the moment and yelled at the top of his voice: "What do you people want?"
"We just want to have a good chat with you." Gu Chen didn't waste any time. He took out his phone directly, showed it in front of Zhang Wenkai and said, "This backpack should be very familiar to you, right? Does it look familiar?"
Hearing Gu Chen's words, Zhang Wenkai immediately retracted his anger, his eyes were stunned, and he hurried to Gu Chen.
When he saw the backpack in the picture on his mobile phone, Zhang Wenkai was suddenly startled and at a loss as to why he said: "What...what is this?"
"This is the travel bag you hid in an alley." Lu Weiwei stepped forward confidently, pointed to the picture on Gu Chen's phone and said:
"The night before yesterday, when Wang Baocheng and He Jun died, you suddenly changed into a black outfit, carried this travel bag, and came to the outskirts of the Tianlu Yaju construction site."
Glancing at the other side of the river, Lu Weiwei immediately said: "Oh, by the way, it's the area on the opposite side. I don't know exactly where it is. Anyway, it should be here."
"you……"
Feeling that his whereabouts were exposed, Zhang Wenkai suddenly went crazy. It seemed that his arrogance last night made it impossible for him to get off stage now.
