I am a super cop

Chapter 1594 Murder Technique

The fat man was dumbfounded by Gu Chen and Lu Weiwei's question, why did he come up with the idea of ​​his own drone?
It can be seen that the eyes of the two are sincere, and they don't want to look like they are joking, so they also ask weakly: "Can you play?"

"Don't you still have you? You might as well lend it to us." Lu Weiwei said cheekily.

The fat man stared blankly, but after a moment of contemplation, he readily agreed, "You guys want to take aerial photos, right? I can take some footage for you for free. Is it now or when?"

"wait for me a while."

As soon as the fat man here agreed, Gu Chen walked directly to the nearby 24-hour convenience store.

Not long after, Gu Chen came out from inside, still holding a bag of things in his hand.

The fat man took a closer look, only to realize that it was a matching blade for a razor.

Gu Chen directly took off one of the blades of the fat man's drone, and began to use super glue to glue one of the sharp blades to the blade of the drone.

After completing the operation, Gu Chen waited quietly for a few seconds, then suddenly walked to the trash can on the side of the road, found a discarded piece of foam, put it under a big tree, and reminded:
"You help operate the drone, fly over here, and help me cut this bubble."

"Cut... cut the foam?" Gu Chen seems to be around 20, right?Why do you still love to play like a child?

Are the police today so boring?
Although I don't know Gu Chen's intentions, but after all, the police did me a big favor.

Not only did he save himself from being beaten, but he also saved his drone.

Even if this young policeman is boring enough, he might as well be bored with him.

After debugging the drone, the fat man put the drone on the ground, then put the mobile phone on the operating handle, and began to debug carefully.

It is also more discreet to handle thanks to the sharp blades glued to the blades.

Gu Chen and Lu Weiwei stood on the left and right sides of the fat man, quietly watching the man operate.

After a while, only a "hum" was heard, and the 4 blades of the drone began to rotate rapidly, and the drone slowly approached the foam.

"Can your night camera see clearly?" Lu Weiwei asked him.

The fat man said confidently: "No problem, mine has 2000 million pixels after all, and I have a Hasselblad 1-inch lens."

"It should be an indisputable fact that if you pay attention to focusing at all times during operation, you can shoot relatively high-definition works."

"I don't need you to take such clear pictures. I just want to be able to see exactly how the blade cuts through the foam in the camera lens. Can this kind of operation be possible?" Gu Chen is also more pragmatic.

After all, I am not idle and doing this kind of boring trick, just to confirm whether the drone at night can do what I want.

The fat man probably understood Gu Chen's meaning, although he didn't know what the intention was, he still managed to do it with difficulty.

On the screen of the mobile phone, the drone began to slowly fly towards the foam according to the positioning of the camera.

Just as it was approaching the bubble, the drone suddenly issued an obstacle avoidance warning, and then paused again.

The fat man didn't know what to do, he turned his head and looked at Gu Chen.

Gu Chen, on the other hand, said resolutely: "Fly over there, if the drone is damaged, we will be responsible for the compensation."

"Okay, it's fine with your words." With Gu Chen's accurate endorsement, the fat man didn't hesitate anymore, and directly pushed the operating handle forward.

With the "buzz" sound of the drone, the long strip of foam placed by the tree was cut into two in an instant.

The drone only vibrated a little, but under the timely adjustment of the fat man, it returned to a stable state in an instant.

"It's done." Gu Chen was overjoyed, and his tense nerves finally relaxed.

The fat man quickly parked the drone to one side, while Gu Chen and Lu Weiwei hurried forward to pick up the cut foam on the ground.

Lu Weiwei came over and said, "Junior Gu, look, the incision is very clean, it's just foam, if it's a human throat, it must have been sealed with a knife."

"That's right." Gu Chen's expression was serious, but he was relieved from the imagination just now: "This is just an ordinary modified drone, only one blade has a blade attached."

"I can't imagine, if the four blades of the drone are all equipped with modified sharp blades, what kind of horror will the result be?"

"So that's why there are no footprints at the scene of the crime?" Lu Weiwei couldn't help but smile from her aunt.

It feels like after a long time of investigation, finally relying on this supper to explain all the doubts clearly.

Lu Weiwei thought that if she didn't eat a full supper, she would feel sorry for her buzzing mind.

"Here." Gu Chen returned the drone to the fat man, and said seriously, "If you break one of your blades, I will pay you how much."

"Are you kidding me?" Seeing that Gu Chen was serious, the fat man who took over the drone also took the initiative to take a step back, complaining:
"Isn't it just that the blade was glued by 502? It's okay. I'll pull the blade off when I go back and scrape off the glue residue. What a big deal."

"That's fine, but I still want to thank you, why don't we come over for a late-night snack?" Seeing that the fat man was easy to talk to, Gu Chen took the initiative to invite him over for a late-night snack.

The fat man glanced at the table of men and women who hadn't left yet, and suddenly said with a guilty conscience: "No...no need, if there is nothing else, I have to go home quickly, I have to go to work tomorrow, so I won't bother you. "

As soon as the voice fell, the fat man also left quickly, feeling that everyone he met tonight was a strange thing.

As for Gu Chen, he was also overjoyed.

The puzzle that had troubled him for a long time was finally solved, and Gu Chen instantly felt relieved. This was definitely the biggest breakthrough tonight.

Before he had time to think about it, Gu Chen immediately took out his mobile phone and started to contact Officer Wang.

The phone beeped a few times, and Police Officer Wang, who was sleeping in the office of the Furong Sub-bureau, answered the phone feebly: "Hey, Gu Chen, how is your investigation going? When will you be back?"

"Senior Brother Wang, we are still eating supper outside."

"Eat supper?" Hearing that Gu Chen and Lu Weiwei were chic outside, Police Officer Wang became a little self-conscious for a moment, and quickly raised his voice: "Then can you bring some chicken legs, duck legs, etc. back by the way?"

"Senior Brother Wang, I have something serious to discuss with you."

"Serious things? Eating... is also very serious, right?" Police Officer Wang also said with a smile.

Gu Chen laughed dryly, and explained seriously: "I already know how the murderer committed the crime."

"Really?" Hearing Gu Chen's words, Police Officer Wang, who was lying on the folding bed in the office, immediately sat up and said involuntarily:

"what happened?"

"I can't explain it for a while now." Gu Chen paused for two seconds, and explained seriously: "You ask Senior Brother He to help you find out. Does this Zhang Wenkai like aerial photography?"

"Wait a minute." Officer Wang just responded, but soon there was no movement.

Not long after, Gu Chen heard He Junchao's wailing on the phone, as if he was awakened from his dream by Police Officer Wang.

After a while, Police Officer Wang replied, "I'll ask He Junchao to investigate. You can bring some food back now. You guys are still hungry."

"No problem." Gu Chen grinned and hung up the phone readily.

In the following period of time, Gu Chen and Lu Weiwei whetted their appetites and ordered a lot of late-night snacks. They didn't bring a few late-night snacks until their taste buds were completely satisfied, and hurried to the Furong branch.

……

……

Back at the branch office, the time has come to 1:50 in the morning.

When Gu Chen and Lu Weiwei pushed open the door, Police Officer Wang and Yuan Shasha were still resting on the folding bed, while the tool man He Junchao was still looking for clues in front of the computer with his eyes wide open.

"Senior Brother He." Gu Chen put a night snack over and reminded, "Eat something first."

"Gu Chen." He Junchao took the supper and reminded him, "How did you know that Zhang Wenkai likes aerial photography?"

"Really?" Gu Chen leaned over and said.

He Junchao nodded silently: "That's right, I called many surveillance cameras on the Tianlu Yaju construction site for investigation, and I found that Zhang Wenkai once played with drones on the construction site."

"And not only that, these people on the construction site are engaged in team building, and Zhang Wenkai has also taken aerial shots for everyone. It can be said that this guy is a veteran player."

"Later, I checked many of Zhang Wenkai's social platforms and found that he is really an aerial photography enthusiast."

"That's right." With He Junchao's affirmative reply, Gu Chen's confidence also increased a bit.

Police Officer Wang and Yuan Shasha, who were awake at this time, also took the supper from Lu Weiwei's hand, moved to Gu Chen's side, and asked in a low voice:

"Gu Chen, what did you find by the river tonight?"

"I didn't find anything, but it seems that I found everything." Gu Chen said.

Officer Wang stared blankly: "Why do your words sound like nonsense literature?"

"So Senior Brother Gu found a clue?" Yuan Shasha was also very curious.

Gu Chen didn't show off, and directly nodded and admitted: "That's right, although we didn't find any clues by the river, but through experiments with a drone, I seem to have found Zhang Wenkai's method of killing people."

"Murder method? Drone?" Police officer Wang has not yet woken up from his sleep, and he hasn't reacted for a while.

Lu Weiwei, who couldn't stand it anymore, was also impatient, and immediately reminded: "Old Wang, have you ever thought about installing sharp blades on the blades of drones, and then using drones to kill people?"

"What?" After being reminded by Lu Weiwei, Police Officer Wang's eyes were bright, and he suddenly realized.

As soon as he slapped his thigh, Officer Wang said excitedly, "Oh, why didn't I think of it? It took us so long to think about such a simple truth."

Looking up at Gu Chen, Police Officer Wang also confirmed and asked: "So Gu Chen, this Wang Baocheng and He Jun all died of this drone killing method, right?"

"If this is the case, the murderer can hide on the other side of the river, directly operate the modified drone, and use the blade on the drone's blade to kill Wang Baocheng and He Jun on the other side without leaving any footprints. The trick is really high."

"So that's the case?" Listening to Police Officer Wang's explanation, Yuan Shasha on the side was also surprised, feeling that this was the truth.

Gu Chen also said cautiously: "This is just a reasonable speculation, but whether it is feasible or not, we just did a simple experiment tonight."

"Go to the supermarket to buy a blade, and use 502 glue to stick it on the blade of the drone, but successfully cut a piece of foam into two."

"I think, if you want to verify the circumstances of the case, you must experiment carefully. At least it can prove that both Wang Baocheng and He Jun died of this murder tool."

"Yes, we must act with caution." Officer Wang walked back and forth in the office, and suddenly kicked He Junchao's stool, reminding him:
"He Junchao, hurry up and check the surveillance video of the last week to see if Zhang Wenkai has bought anything like blades."

"I found it, don't worry." He Junchao made a few simple operations, and then retrieved a few video files, reminding him:
"Anyway, Zhang Wenkai doesn't leave the construction site many times. The last time he left the construction site, apart from going to the group building in your Wangjia Village, that is, a week ago, he went to the nearby supermarket."

"Then where is his travel bag now?" Gu Chen asked again.

He Junchao replied: "Judging from his return to the hospital that night, after he still entered the blind spot in the alley, he changed his previous clothes and came out from another exit. His things should still be in the alley."

"But don't worry, I have already notified Ding Liang and Huang Zunlong to look for them, and there must be results soon."

"I can't wait." It was getting closer and closer to the truth, so Gu Chen didn't have time to think about it, so he took out his phone and started contacting Ding Liang and Huang Zunlong.

After a while, Ding Liang's cell phone was connected, and he asked directly, "Gu Chen, what's the matter?"

"Where are you now?" Gu Chen asked.

Ding Liang was a little frustrated and said: "In a small alley near the hospital, Brother He asked us to search for a travel bag, but we have been searching here for a long time, but we still can't find it. It's really annoying."

"Send me your location, and I'll come over now."

"What? Are you coming?" When he heard that Gu Chen was coming, Ding Liang said with some distress: "I said Gu Chen, it's already 2 o'clock in the morning, you should take a rest, besides, we have a lot of people here, Not bad for you."

Originally, I wanted Gu Chen to have a good rest. After all, even a field team could not be found, so it would be futile for Gu Chen to come here.

Thinking about it, it would be better to let Gu Chen stay at the police station.

But Gu Chen was determined. After a brief conversation on the phone, Gu Chen hung up the phone directly, and was ready to pack up his things again and go to the alley.

Officer Wang was a little stunned and said, "Gu Chen, aren't you tired? It's already 2 o'clock in the morning."

"I'd rather investigate the case than rest." After putting on his police gear, Gu Chen glanced at Lu Weiwei.

Originally, she wanted to go there alone, but she didn't expect that Lu Weiwei had already put on her equipment, as if she wanted to go out with Gu Chen.

Gu Chen understood Lu Weiwei and didn't say much, the two nodded in tacit understanding and left the office again.

Seeing the backs of the two disappearing, Yuan Shasha hesitated and said, "These two are really exhausted? I must have collapsed."

"Lu Weiwei must be exhausted, but Gu Chen, this guy has always been a hard worker, as long as there is a case, he is like a chicken blood, and he never feels tired."

"Lu Weiwei is just following Gu Chen, if she can be so self-motivated, otherwise she will be more salty than I was back then."

Thinking about the new progress in the case now, Police Officer Wang can naturally understand Gu Chen and Lu Weiwei's bloody work.

Then, after wrapping up the supper in a plastic bag, throw it into the trash can beside him, and continue to lie on the foldable bed to rest for a while.

……

……

On the other side, when Gu Chen and Lu Weiwei drove to the intersection of the alley, it was already 2:30 in the morning.

The police cars of Ding Liang and Huang Zunlong were also parked at the intersection of the alley.

At this time, the two of them were also taking two auxiliary policemen, lying on the corner of the alley to rest.

Maybe it was because they were too tired, but when they saw Gu Chen and Lu Weiwei approaching, they were a little reluctant to get up.

When Gu Chen came to Ding Liang, he didn't say much, and started to search the surrounding environment.

"Don't look for it." Huang Zunlong said a little tiredly: "In fact, this alley is not long, and there are only a few families living here, but we have asked all of them, and these few residents have not seen any trace of Zhang Wenkai. "

"Moreover, these residents asked us to search the house, and we didn't find any trace of the travel bag."

"Yes." As soon as Huang Zunlong finished speaking, an auxiliary policeman also complained, "It can be said that we dug three feet of ground in this alley, but we don't know where that travel bag is hidden. "

Gu Chen didn't reply, but continued walking along the alley.

In 10 minutes, Gu Chen had walked both ends of the alley three times.

This alley has a curved arc, so from the intersection on both sides, the middle position cannot be seen at all.

Gu Chen thought that Zhang Wenkai had to change his clothes in the alley and fetch his backpack.

In terms of time, it is very urgent and takes a very short time.

This means that the backpack may be hidden in the middle of the alley.

Walking to the middle of the arc-shaped alley, Gu Chen could no longer see the exits on both sides.

"This should be the best place to hide things, right?" Gu Chen murmured in his heart.

After all, even if Zhang Wenkai needed to change his clothes, it would be impossible for passers-by at the exit to see him.

At the very least some shelter is needed.

The middle position of the curved alley is a good solution to this problem.

Standing in the middle of the arc-shaped alley, in front of you is the outer wall of a former building, and there are no doors or windows nearby.

There are only three families in the alley, two of which are located at the two exits, and the other one is also close to the exit. There is only one small door in the alley.

Gu Chen went over to check it, the door lock was rusty and almost untouched.

Thinking of this, Gu Chen looked up and down, and suddenly he knew it.

"It's impossible for Zhang Wenkai to put Dong XZ in the sky, right? If not, then it's underground." Gu Chen decisively walked to Ding Liang's resting position.

Ding Liang stared blankly, looked up at Gu Chen and said, "Why?"

"You only searched these three houses, right?" Gu Chen asked.

Ding Liang nodded silently: "That's right, Arhat climbed over the wall and sat on the wall to observe."

"The wall in this place is very high. It is actually difficult to climb over it by one person alone, and we have not found any traces of climbing around the wall."

"Then it should be buried underground." Gu Chen walked back and forth twice in front of Ding Liang to determine the center of the arc-shaped alley, which happened to be relatively close to where Ding Liang was sitting.

And this arc-shaped alley has only one underground passage, which is covered by cement slabs.

The edge area between the cement boards has a groove structure, and the two cement boards are spliced ​​together to form a drainage gap.

Gu Chen directly touched Ding Liang's butt with his foot.

Ding Liang was stunned, and hurriedly asked Gu Chen: "What's wrong with you?"

"Stand up." Gu Chen reminded.

Ding Liang, who was at a loss, didn't quite understand Gu Chen's intentions. He just felt a little curious, but he still obeyed.

He stood up, patted the dust off his body, and gave way.

At this time, Gu Chen was sticking his body to the ground, carefully observing the cracks in the cement board, and really quickly discovered the problem.
