Take out the bright flashlight, Gu Chen irradiates around the cement board twice, points to the gap and says, "there are obvious signs of movement in the gap of the cement board. Why didn't you find it?"
"What? There are traces of movement?" hearing Gu Chen's words, Ding Liang was also anxious and hurriedly bowed his head to observe.
But even if he observed carefully, he didn't exaggerate as Gu Chen said. He immediately asked Gu Chen, "how do you see it?"
"The dust covered on the cement board has obvious friction marks," Gu Chen said.
"I was sitting here just now. Could it be the trace of my butt rubbing?" Ding Liang also had something to say about sitting here to rest just now.
But Gu Chen shook his head to deny it, waved a friction trace and said, "your ass can't cover the whole cement board, like the gap near the wall. These are dead corners. Just by the area of your ass, you can't rub the dead corner at all."
"Poof!"
Listen, Gu Chen is here to discuss the area of his ass with Ding Liang. Lu Weiwei and several others can't help laughing.
Ding Liang was a little embarrassed. He also scratched the back of his head and said with a sneer: "so, things have been hidden under my ass?"
"Is it right? Just dig it out and have a look." Huang Zunlong asked Ding Liang to give way to his birth position, while he took the initiative to walk up to him and clasped his hands on both sides of the cement board for analysis.
I thought it was a heavyweight guy, but with just a slight mention, the cement board was pulled out.
A travel bag wrapped in a large plastic bag is placed in the middle so quietly.
Seeing this, everyone was overjoyed.
Lu Weiwei was also excited and said: "looking for a long time, it turned out that this travel bag was here. Ding Liang was sitting below. It was really dark under the light."
"How do I know this thing is here?" Ding Liang was a little dissatisfied and directly asked Gu Chen, "by the way, Gu Chen, how are you sure that this thing is where I rest?"
"Let's judge by intuition." Gu Chen went to the cement board and pointed to the arc channels on the left and right sides, explaining:
"If a normal person hides something, it must not be seen by passers-by?"
"But this arc alley, I walked back and forth three times, and found that only you are the dead corner of the alley."
"Because things are buried here, pedestrians can't see the alley exits on the left and right sides."
"And it's very strange. As long as the upper position moves a meter or two to your left and right sides, it may be found by pedestrians at the intersection on both sides of the alley. Do you say God is not magical?"
"So?" thinking of Gu Chen's judgment, Ding Liang immediately admired and said, "fortunately, you Gu Chen's horse, otherwise you don't know what time to be busy tonight?"
"It's stupid to hide under my ass and I don't know it yet."
"It's a good thing to have self-knowledge. It means you still have room for further study. Let's go."
Lu Weiwei's voice fell. She had put on her white gloves and pulled Ding Liang and others aside.
He carefully picked up the large plastic bag and blew the dust in his hand.
At the moment, Gu Chen also put on white gloves. With the cooperation of Lu Weiwei, he carefully untied the plastic bag and then tore the zipper of the travel bag.
With her hands propped up, Lu Weiwei hurriedly asked, "brother Gu, what do you see? Is it the UAV?"
"That's right." Gu Chen takes out a UAV from his travel bag.
Ding Liang quickly shines a bright flashlight on Gu Chen.
Under the bright light, Gu Chen carefully observed the structure of the UAV with master observation.
The host is intact. Gu Chen gently gives it to Lu Weiwei.
Then he continued to look in his travel bag, but he never found the trace of the blade.
Gu Chen was shocked and murmured, "this UAV lacks flying blades, only the main engine."
"It must be that Zhang Wenkai threw away the flying blade with blade after committing the crime." Lu Weiwei knows Zhang Wenkai very well.
This guy is cunning. After committing the crime, he will certainly discard the blade and separate it from the UAV. It's normal that he can't find it.
Gu Chen nodded silently, and then took the UAV from Lu Weiwei again for observation.
Through the light, Gu Chen found that there were several scratches on the unmanned fuselage.
But look carefully, but there are traces left, and my heart is also cluttering.
But a moment later, Gu Chen's hanging heart suddenly relaxed again, and the corners of his mouth gradually raised an upward arc.
Lu Weiwei found that Gu Chen's face changed and hurriedly asked Gu Chen, "younger martial brother Gu, have you found anything?"
"That's right." Gu Chen measured the inclination of the fuselage, lit it in front of Lu Weiwei, pointed to a gap and said: "the blood of Wang Baocheng and He Jun may have been stuck on this UAV."
"After all, high-speed rotation, coupled with a sharp blade, will cut each other's neck artery. At the same time, blood will certainly splash the fuselage."
"But Zhang Wenkai will wipe the blood," Ding Liang said.
Gu Chen continued to nod: "you're right. Wiping the blood is for sure, but you may not be able to clean some parts, such as this and this."
Gu Chen randomly pointed to several gap positions.
The crowd gathered together and took advantage of the light to cover it. When they looked at it, they really found several traces of blood.
Seeing this, Lu Weiwei was also overjoyed and said, "great. Zhang Wenkai is still careless. It is estimated that he can't wipe these gaps, but just wipe the blood on the surface and fuselage of the UAV."
"Then send it to the Technology Department of the Municipal Bureau and ask Gao Chuanfeng to extract these blood to see if it belongs to the dead Wang Baocheng and He Jun?" Huang Zunlong on the side is also anxious at the moment.
I felt that I had made such a great discovery and was not tired, so I wanted to get the results quickly.
Gu Chen smiled faintly and said slowly, "I don't need to test. I know that the blood must belong to Wang Baocheng and He Jun, but in order to go through the procedure, I'd better send it."
"Leave this to us." Ding Liang felt that he had been here in vain for a long time, and he was immediately embarrassed.
So he quickly sent the physical evidence to the technical section of the Municipal Bureau for testing and took it down.
Lu Weiwei grinned and reminded, "you don't look at what time it is. You send it over at this time. Gao Chuanfeng is already seeing Duke Zhou."
"Then wake him up. I know that maple takakawa must be on the night shift in the Technology Department of the Municipal Bureau these days."
When Ding Liang was doing order maintenance at the scene of the crime, he had a few words with the forensic Feng takakawa.
I know that maple takakawa has been in the testing room all this time.
Lu Weiwei smiled and continued to remind: "if so, it's best, but you also need to remember that Gao Chuanfeng's famous family is chicken legs."
"Even if he is impatient, as long as you add chicken legs to the takeout, it will work well."
"True or false?" Ding Liang, who has always had little contact with forensic Feng Gaochuan, was also skeptical.
But since Lu Weiwei said so, it doesn't feel like a problem.
The time has come to 3 a.m.
After we finished the simple handover at the scene, wrapped all the physical evidence in large evidence bags, numbered and photographed for evidence collection, Ding Liang and Huang Zunlong's team took the physical evidence to the technical section of the Municipal Bureau and handed it over to Gao Chuanfeng for treatment.
Gu Chen and Lu Weiwei are finally relieved and ready to return to Furong Branch to continue to sleep.
……
……
The next morning, the sun was shining.
Early in the morning, Yuan Shasha had brought everyone's breakfast.
At this time, officer Wang just woke up, but saw that Gu Chen and Lu Weiwei had started their day's work.
Calm down, officer Wang quickly asked, "by the way, Gu Chen, did you get anything from going to that alley with Lu Weiwei last night?"
"Of course there is." Gu Chen grinned when he saw that officer Wang had woken up.
Before officer Wang could answer, Lu Weiwei quickly interrupted: "we found Zhang Wenkai's backpack hidden there in that alley last night. Lao Wang, guess what's in the backpack?"
"What?" officer Wang looked up and thought, and said weakly: "is it a UAV?"
"That's right." Lu Weiwei shook her finger and continued to explain, "this is a high-grade UAV with blood stains. There are blood debris between the gaps of the UAV."
"At present, we have asked Ding Liang and Huang Zunlong to take Gao Chuanfeng for testing. It must not be long before we can get the results."
"If so, it would be great." officer Wang was relieved to hear what they said.
But suddenly, officer Wang asked, "what are you doing getting up so early? You should have been busy very late yesterday?"
"It's already 3:30 in the morning," Gu Chen said.
Officer Wang looked unbelievable and stared at Gu Chen and Lu Weiwei carefully.
Lu Weiwei's face was slightly broken, but Gu Chen was radiant without any trace of fatigue.
This made officer Wang feel that people at their current age are really anti-aging.
Shaking his head, officer Wang came directly to Gu Chen and found that Gu Chen was already sorting out today's action.
Some materials are also being drafted, including two dummies.
Officer Wang looked into the clouds and hurriedly asked Gu Chen, "Gu Chen, what are you going to do?"
"I want to expose Zhang Wenkai," Gu Chen said.
"Expose it in public?" officer Wang asked again, "is it to confirm the fact that he killed?"
"Of course." Lu Weiwei came up and told the truth: "Zhang Wenkai is cunning enough. If we can't prove that he killed people with drones, this guy will certainly argue."
"So brother Gu discussed with me and asked the Technology Department of the Municipal Bureau to borrow two dummy models to demonstrate his modus operandi in front of everyone."
"Then you have to inform Zhang Wenkai to be present." officer Wang felt that this method was good, but Zhang Wenkai himself had to be present.
Yuan Shasha, who was eating breakfast, said, "elder martial 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 we should come back early. We can just go directly to the Tianlu Yaju construction site to meet them."
"Great." officer Wang snapped his fingers excitedly and said, "if so, everything is ready now, only the east wind is owed."
Looking up at Gu Chen, officer Wang asked, "have you implemented the problem of UAV modification?"
"Elder martial brother he has been asked to borrow a UAV of the same model and then change it," Gu Chen said.
Officer Wang nodded silently and asked, "what about the Technology Department of the Municipal Bureau? Any news?"
Gu Chen shook his head: "at present, I'm waiting for their test results. If there are results at the first time, I'll ask them to send me a test report by mobile phone."
"Ding Liang and Huang Zunlong have also brought the borrowed dummy model to Tianlu Yaju. Elder martial brother Wang is waiting to see a good play."
"Good, very good." seeing his efforts to take a nap and sleep, Gu Chen has arranged everything in order.
Officer Wang suddenly felt that he had become an idle man.
At this time, Feng Gaochuan, the forensic physician of Cao Cao's attribute, suddenly called.
Without saying a word, Gu Chen picked up the mobile phone on the desk, directly crossed the answer button, and clicked hands-free: "Feng Gaochuan, what are the survey results over there?"
"As you wish." Maple takakawa yawned and said weakly, "I have extracted the blood in the gap of the UAV."
"As like as two peas, Wang Baocheng and He Jun's blood are the same as those detected and contrasted."
"It can be said that the UAV was stained with the blood of two people."
"That's right." Gu Chen was delighted when he got the reply from Feng takakawa and said, "with this result, Zhang Wenkai's sophistry is futile."
"Feng takakawa, please send me the test report immediately. I'll rush to the scene immediately."
The voice fell, but there was no movement.
Gu Chen looked at his colleagues. He was also curious, so he asked, "Maple takakawa, are you listening?"
"Listen." takakawa Feng's response seemed strange.
Gu Chen was puzzled and asked, "what's the matter with you?"
"That's what." I felt it necessary to make it clear to Gu Chen, so takakawa Feng also took the initiative to explain:
"It was almost 4 a.m. yesterday. Ding Liang and Huang Zunlong from your Furong Branch sent the evidence and called me to wake me up, causing me to test you all night."
"Hard work, maple takakawa." knowing that maple takakawa is also very hard, Gu Chen also quickly thanked and comforted.
But Gao Chuanfeng said, "that's what. They said they owed me two chicken leg takeout. When they borrowed the dummy model, they didn't mention it."
"If they don't mention it, you have to remember. After all, I'm also very hard. You Gu Chen is responsible for whether you can have a takeout meal with chicken legs this noon and evening."
"Ha ha, well, I'll convey it to them." I feel it's really interesting to talk to Feng takakawa. Gu Chen simply promised to come down first.
After a brief exchange, they both hung up.
And takakawa Maple soon sent his test results in the form of documents.
And Gu Chen has evidence, and there is no need to stay in the police station.
Immediately let everyone clean up and prepare to go to Tianlu Yaju construction site.
……
……
8 a.m.
When most workers have come to the construction site to prepare for the day's work.
Gu Chen several people drove the police car over.
Ding Liang, Huang Zunlong and two other auxiliary police arrived at the scene in advance.
Bully Liu Shuheng, accountant Hu Xudong and Zhang Wenkai were all temporarily called outside.
We put the dummy at the crime scene and then set up a cordon around.
Zhang Wenkai obviously felt that he had been controlled by the police early this morning.
Since he came to the periphery of Tianlu Yaju construction site, he has been standing around Zhang Wenkai with Ding Liang and Huang Zunlong's two auxiliary policemen.
Until Gu Chen's arrival, Zhang Wenkai didn't know why. He hurriedly asked Gu Chen, "Comrade police, I said it. Before, it was a misunderstanding."
"Even if I'm sorry for my girlfriend, it's an emotional problem between me and my girlfriend, so I hope you don't intervene too much."
Pointing to himself, Zhang Wenkai said, "I know I'm wrong now. I'll change it later. Also, I want to apologize to you for my irrationality last night. After all, I'm not a murderer, and you don't have to be so alert to me."
"Zhang Wenkai." see Zhang Wenkai up to now, but still put on a hypocritical face.
Gu Chen walked up to him, but he didn't have a good way: "do you know the purpose of calling you here today?"
"Purpose?" Zhang Wenkai looked around and saw two dummy models placed at the crime site. He immediately hesitated and said, "I don't know. Are you investigating the case?"
"In fact, we all know who the murderer is." Lu Weiwei didn't have a good airway when she saw Zhang Wenkai's fine upper body.
Zhang Wenkai sneered back at Lu Weiwei and said, "Comrade policewoman, you should be responsible. Don't you slander me by saying so?"
"Moreover, I made it clear in the hospital ward yesterday that the death of Wang Baocheng and He Jun had nothing to do with me. I also feel sorry for them. I......"
"Zhang Wenkai, you can really pretend." officer Wang can't see it anymore. He feels that if he doesn't stop this Wen Kai outfit, this guy really kicks his nose and face.
Zhang Wenkai replied coldly, "what do you say? Why should I pretend? You policemen are really interesting. If you can't solve the case yourself, you are always suspicious. Everyone looks like a criminal."
Pointing to himself, Zhang Wenkai also said righteously: "I Zhang Wenkai really don't have time to play with you. My leg injury hasn't recovered yet. I have to go back and cultivate for a few days."
The voice fell, and Zhang Wenkai turned around to leave.
But he was pushed back by two auxiliary policemen in an instant.
Two steps backward, Zhang Wenkai was very angry at the moment. He also opened his voice and roared, "what do you people want?"
"We just want to have a good chat with you." Gu Chen didn't talk nonsense. He took out his mobile phone directly and Liang said in front of Zhang Wenkai: "you should be very familiar with this backpack? Do you look familiar?"
Hearing Gu Chen's speech, Zhang wenkaidun took back his anger. He was also stunned and hurried to Gu Chen.
Looking at the backpack in the picture of the mobile phone, Zhang wenkaidun was surprised and was at a loss: "this... What is this?"
"This is your travel bag hidden in an alley." Lu Weiwei also walked forward righteously, pointed to Gu Chen's mobile phone picture and said:
"The night before yesterday, when Wang Baocheng and He Jun died, you suddenly changed into a black dress, carried this travel bag and came to the periphery of Tianlu Yaju construction site."
Glancing across the river, Lu Weiwei immediately said, "Oh, yes, it's the area opposite. I don't know where it is. It should be here anyway."
"You..."
I felt that my whereabouts were exposed. Zhang wenkaidun was a little crazy. It seemed that his arrogance last night made him unable to stand down now.
