Everyone seems to have grasped Zhang Wenkai's destiny. Just this photo has already made Zhang Wenkai confused.
In addition, everyone knew what happened when Zhang Wenkai went to the opposite side of the Tianlu Yaju construction site that day, which made Zhang Wenkai even more unclear.
Seeing the evidence in front of him, Zhang Wenkai tried to calm down and then said: "Okay, even if this backpack is mine, so what?"
"Where I hide my backpack is my own business. Is this also illegal?"
"Of course it's not illegal, but I want to know what you were doing on the other side of Tianlu Yaju the night before yesterday?"
"Me?" Faced with Gu Chen's question, Zhang Wenkai seemed to have not thought of an answer for a while.
At this time, Lu Weiwei took advantage of the situation and pursued her, and asked: "Also, what's going on with the drone in your bag?"
"No... drone?" After thinking for a while, Zhang Wenkai suddenly said: "Yes, I... I just went there to collect materials. I am an aerial photography enthusiast."
"Are you an enthusiast level enthusiast?" Officer Wang asked.
Zhang Wenkai nodded silently: "That's right."
"I've seen your drone. Why does it have no flying blades?" Gu Chen asked.
Zhang Wenkai hesitated for a few seconds and then quickly replied: "It's nothing, the blade is lost."
"Lost it?" It felt like Wen Kai didn't even draft what he said. Lu Weiwei took a step forward and asked:
"That is to say, the night before yesterday, you were carrying a travel bag with a drone on your back. At the time of the crime, you ran to the other side to take aerial photography, but you lost the blade. Then you still took a hammer?"
"I……"
Being pressed so hard by Lu Weiwei, Zhang Wenkai didn't know how to organize his words.
But Lu Weiwei remained unyielding and continued to add: "Whether you lost the leaves or deliberately discarded them, you have to make it clear."
"This...what do you want me to say?" It felt like Lu Weiwei was a bit too bullying, but Zhang Wenkai was in an absolute disadvantage at this time.
All conditions are not favorable to you.
Thinking about last night, I could take advantage of the fact that the police were unable to grasp clues and make various jokes about the police's handling of the case.
But now it seems that I have fallen into a trap.
It only took one night to put the evidence in front of them.
This kind of work efficiency is more like being angry with yourself.
But unfortunately, it seems that I lost the bet, and the police now firmly hold the initiative.
When Gu Chen saw that Zhang Wenkai refused to plead guilty, he also said jokingly: "Actually, we have already mastered the methods of committing crimes of yours."
Pointing to the two dummy models at the crime scene, Gu Chen added: "You notified Wang Baocheng and He Jun in advance that day, and asked them to come to this location at different times, and then use your modified drone
, kill two people here one after another, right?"
"You...what are you talking about? What drone? Why did you invite them to come here? I...I don't know what you are talking about?"
Faced with Gu Chen's questioning, Zhang Wenkai was obviously at a loss.
Gu Chen actually revealed all the methods of committing the crime.
But Zhang Wenkai still can't believe that in just one night, after he slept, all the situations were completely reversed.
Why is Zhang Wenkai so crazy? It's because the reversal was too fast, which gave Zhang Wenkai no time to adapt.
At this time, Liu Shuheng, who was standing on one side, was also confused, so he quickly asked Gu Chen:
"Officer Gu, do you think the murderer is Zhang Wenkai?"
"That's right." Gu Chen nodded silently.
Liu Shuheng looked confused and asked again: "You also said that he used drones to kill people?"
"Yes." Gu Chen still nodded to confirm.
Liu Shuheng was even more confused now, and asked with a puzzled face: "But how did he do it?"
"Don't worry, I'll tell you the answer right away." Feeling that it was time to start his live demonstration, Gu Chen took out his mobile phone and dialed He Junchao's number directly.
Not long after, two police officers suddenly appeared on the other side. He Junchao called a colleague who was operating a drone to him, and seemed to be giving him some instructions.
Seeing that the time was right, Gu Chen also took the phone to remind him: "Brother He, let him start now. The target is the throat area of the No. 1 dummy model."
"Understood." He Junchao on the phone heard this and immediately informed his colleagues around him.
At the same time, two auxiliary police officers directly removed the No. 2 dummy model, placed the No. 1 dummy at the crime scene, and asked everyone to retreat outside the cordon.
Not long after, a roar suddenly came from the sky.
A drone flew at high speed, and when passing in front of the No. 1 dummy model, it suddenly approached slowly.
After only staying briefly for a few seconds, the drone suddenly approached the dummy. It flew at an ultra-fast speed and quickly used its flying blades to leave a wound on the neck of Dummy No. 1.
Dummy No. 1 suddenly fell to the ground while being attacked.
The drone bumped briefly for a few times, quickly regained its balance, and flew directly towards the other side of the river.
When Liu Shuheng saw this, he was stunned and asked Gu Chen: "Officer Gu, this..."
"This is Zhang Wenkai's modus operandi." Gu Chen said.
Liu Shuheng glanced at Zhang Wenkai, who was bowing his head in silence, then at the mannequin that fell to the ground, and asked, "Can I go over and have a look?"
"Of course." Gu Chen nodded silently, then walked through the cordon and came to the fallen mannequin with Liu Shuheng.
Liu Shuheng picked up the dummy and carefully inspected the neck of the dummy. He was shocked to find that there were several cuts on the neck.
Liu Shuheng was a little puzzled and asked curiously: "How can this drone be so powerful?"
"You idiot, can't you see it now?" Officer Wang saw that Liu Shuheng still didn't understand, so he sighed and took the initiative to explain:
"This drone has been modified. The four flying blades are equipped with sharp blades."
This chapter is not over, please click on the next page to continue reading! "These blades must be light enough so as not to affect the flight of the drone, and the high-speed blade rotation is undoubtedly the same as the power of a chainsaw."
Glancing at the dummy model with its throat cut on the ground, Officer Wang also said helplessly: "That's why this dummy's throat was sealed with a knife."
"Senior Brother Wang is right." Seeing that Officer Wang had already explained the whole story clearly, Gu Chen continued to add:
"This dummy model was borrowed from the testing room of the Municipal Bureau's Technical Department. It is a highly realistic human body model."
"Even the toughness of the external skin is not much different from human skin."
Pointing to the throat of the dummy model, Gu Chen added, "Did you see it? These knife marks are exactly the same as those left on the necks of the deceased Wang Baocheng and He Jun."
"Every knife edge is exactly the same, and the depth of the knife mark is exactly the same."
"So that's what it is?" After hearing Gu Chen and Officer Wang's explanation, Liu Shuheng also frowned and turned to look at Zhang Wenkai who lowered his head and said nothing. He was also furious at this moment:
"So the murderer is really you?"
"No...it's not me." The trembling Zhang Wenkai still refused to admit his guilt and continued to deny: "Both of them were at the scene. How could I kill two people in a row with a drone? It was still the same person.
Wounds, this is unscientific."
"Haha, you are really cunning." Seeing Zhang Wenkai still making the final struggle, Lu Weiwei, who was standing by, couldn't stand it anymore and reminded her directly:
"Didn't you hear what my junior brother Gu said just now? You arranged for these two people to come here in order."
"I can assume that you first invited Wang Baocheng to come to the scene at the specified time, and then you hid on the other side of the river and operated the drone, using the drone's camera device to accurately arrive in front of Wang Baocheng."
"Wang Baocheng didn't know why and thought someone was playing a prank. You took advantage of the moment when Wang Baocheng let down his guard and suddenly put the drone towards Wang Baocheng's throat."
After a pause, Lu Weiwei added: "Wang Baocheng didn't know that the blades of this drone were modified blades because he couldn't dodge."
"So after your throat was cut, you quickly fell to the ground and died. At this time, you took back the drone and continued to hide on the other side and wait silently."
"He Jun appeared next." Without waiting for Lu Weiwei to explain, Gu Chen directly took over and said:
"From the way the two people fell to the ground at the scene, we can see that He Jun's arms were stacked on Wang Baocheng's body, indicating that He Jun was a latecomer."
"After arriving at the scene, he found Wang Baocheng lying on the ground, so out of curiosity, He Jun hurried over to check the situation."
"But you just took advantage of this gap to fly the modified drone over again, using the same trick just now to stop briefly in front of He Jun."
"On the one hand, you are letting He Jun relax his vigilance and become curious about the drone. On the other hand, you are also calibrating the position. Then, you use the drone's light and fast flight characteristics to quickly catch He Jun off guard.
One hit kill."
Walking up to Zhang Wenkai, who bowed his head silently, Gu Chen also continued: "You took advantage of this condition and killed two people here one after another."
"And he was able to escape without leaving a murder weapon. This is why, only the bodies of Wang Baocheng and He Jun were found at the scene, but no murder weapon was found."
"Moreover, only the footprints of Wang Baocheng and He Jun were left on the muddy scene, and there was no reason why there were any footprints of a third party."
"Oh my god, so that's what it is?" Hu Xudong, who was standing outside the cordon and staring blankly at everyone, was also shocked by Gu Chen's explanation.
This is indeed a question I have never thought about.
Not only Hu Xudong, but Liu Shuheng was also surprised at this moment.
What everyone originally thought was a strange case, but under Gu Chen's demonstration, everything seemed to be revealed.
Zhang Wenkai, who was standing there shivering, could no longer suppress the madness in his heart and continued to make his final death struggle: "Even if what you said makes sense, why do you conclude that I used a drone to kill this person?"
Two people? Which eye did you see it with?"
"Zhang Wenkai, you are really shameless." Seeing Zhang Wenkai's still strong retort, Lu Weiwei's lungs almost exploded with anger.
I feel like this guy won't plead guilty unless he comes up with something real.
Thinking of this, Gu Chen already showed the screen of his mobile phone again and reminded:
"This is the test result we got early in the morning. We extracted some blood samples from the gap in your drone."
"After the forensic colleagues from the Technical Section of the Municipal Bureau worked overtime, we finally found the source of these blood samples."
After a pause, seeing Zhang Wenkai's confused face, Gu Chen said directly: "These blood samples extracted from the gaps in your drone completely match the blood samples from the wounds of the deceased Wang Baocheng and He Jun."
"If you didn't kill these two people, then why did their blood samples appear in the gaps of your drone?"
Seeing that Zhang Wenkai was speechless, Gu Chen asked and answered himself: "It doesn't matter if you don't say it. I can explain it to you, because this drone is the tool you used to kill Wang Baocheng and He Jun."
"After you committed the crime, you tried to wipe away the remaining blood stains on the drone. However, because it was night and the light was insufficient, you only wiped off all the blood stains on the main body of the drone, but ignored the gaps in the drone.
Subtle bloodstains in between.”
"But I'm sorry, even if you wipe off all the blood stains on the main body, we can still use the little blood stain in the gap to extract the blood sample."
"So what if you throw away those modified flight blades? Do you think you can avoid detection this way? You take it for granted."
"Crack!"
After listening to Gu Chen's explanation, Zhang Wenkai knew that he was doomed. His legs suddenly went weak and he knelt on the spot.
When Liu Shuheng saw this, he also pointed at Zhang Wenkai and said angrily: "Zhang Wenkai, I have always regarded you as my brother, but you cheated on me like this?"
This chapter is not over yet, please click on the next page to continue reading! "When we usually have team building dinners, I remember that you don't even dare to kill a live chicken. How can you kill someone?"
"Haha." After hearing Liu Shuheng's words, Zhang Wenkai also laughed dryly and nodded silently:
"That's right, I don't even dare to kill chickens. If I were faced with live poultry, I really wouldn't be able to do it."
"But the drone can be controlled remotely, just like playing a game. I don't have to directly face the living body to complete the kill, which gives me a certain degree of convenience."
"But why did you want to kill them?" Lu Weiwei was very puzzled and asked curiously.
Zhang Wenkai sniffed, covered his cheeks with his hands, and said with a look of repentance: "For life."
"For life?" Officer Wang snorted coldly and said angrily: "Are they two hindering your life?"
"One of them is a construction geological inspector and the other is a building materials supplier. Why did you do this to them?"
Officer Wang still doesn't understand the subtle relationship between these people.
After all, they are different professions. If we want to talk about the connection, it may be the three batches of building materials that have been put into storage.
But Officer Wang wanted to hear Zhang Wenkai’s own explanation.
Zhang Wenkai was completely desperate at this time.
The method of committing the crime was solved by Gu Chen in just one night, which made him happy but it only took him a few sleeps.
Zhang Wenkai still doesn't quite understand how Gu Chen did it?
Thinking that the murder case he carefully planned was solved by Gu Chen, Zhang Wenkai felt unwilling, but he could only admit it:
"Originally, I didn't want to attack these two people. They were aggressive and a bit bullying."
"I know I'm just an accountant, but I just want to make more money, marry my girlfriend, and live a decent life."
"But these two guys have always been greedy. They took advantage of my weakness of urgent need for money to get married and pulled me into trouble. But I saw batches of low-quality steel being transported to the construction site and used as building materials."
"At that time, I was already panicking. I knew what this meant. If there were quality problems in the building, people would die."
"Please tell me clearly, what's going on?" Liu Shuheng, who had already learned from Gu Chen that there were problems with these three batches of building materials, was also very nervous at this moment.
It seems all this is true.
Zhang Wenkai let out a long sigh and said helplessly: "Brother Liu, I'm sorry, your quality inspector Wang Baocheng is actually from He Jun."
"It's impossible. Wang Baocheng has been with me for so many years. I know his character very well. It's impossible for him to make this kind of money without conscience. It's impossible."
To this day, Liu Shuheng still refuses to believe that Wang Baocheng is such a person.
But the reality is cruel, and Zhang Wenkai continued to explain: "Wang Baocheng is indeed a good quality inspector. I believe him in this, but he also has his own difficulties."
"His lover is gambling with others without telling him, and he has long been in debt."
"Later, the creditor came to her door and threatened to chop off her fingers if she didn't pay back the money. And Wang Baocheng was a man who doted on his wife. He couldn't bear the thought of his wife becoming disabled like this."
"But if the money cannot be repaid, even if the creditor does not chop off his fingers, his wife will have to go to jail, and even the house will have to be auctioned off."
After sniffing, Zhang Wenkai also said helplessly: "This may be a human weakness. Later, when He Jun heard about Wang Baocheng's situation, he used his brain."
"One day, He Jun called Wang Baocheng to dinner. Before leaving, he handed him 20,000 yuan and asked him to quickly get the money to pay off his debt."
"20,000 yuan? Is 20,000 yuan enough to repay the debt?" Yuan Shasha expressed confusion.
But Zhang Wenkai also grinned and shook his head: "Of course 20,000 yuan can't pay off the debt. It can be said to be a drop in the bucket. But He Jun also opened the skylight and spoke frankly. He told Wang Baocheng that as long as he released the water on these three batches of steel, don't inspect too much.
Be too careful."
"When the time comes, He Jun is willing to give up 30% of the extra profit, which is a huge sum."
"So Wang Baocheng agreed?" Liu Shuheng asked.
Zhang Wenkai nodded silently: "If it had been the original, Wang Baocheng would not have agreed to it even if he was killed. But now, Wang Baocheng is in debt and his house is going to be auctioned off. That is his lifelong hard work."
"Later, there was really nothing else to do. Wang Baocheng went home and thought about it all night. Then he called He Jun the next day and agreed to his request."
"So that's it?" Officer Wang heard Zhang Wenkai's words and was thoughtful: "But how did you get involved?"
"Me?" Zhang Wenkai pointed at himself and said with a smile: "I shouldn't be friends with them. If I hadn't accidentally discovered the billing problem when I was doing the accounting, maybe I wouldn't have been involved at all.
