Laser experts are not easy to find, especially those related to weapons. Xu Zheng thought about it and borrowed two technical policemen from the technical investigation department to prepare an on-site simulation to study the path of the laser that burned Ding Xin.
First determine which car it is.
The laser emits from the laser transmitter used by the murderer exceeds the range specified by the toy factory and is a lethal weapon. Xu Zheng and the others could not find such laser weapons for a while.
So they just bought a few toy laser transmitters, like small flashlights, which Xu Zheng had played with when he was a child.
The simulation is actually very simple, that is, the two cars in front and behind are equipped with intelligent assistance systems at the same time, the speed is set to 80 yards, and then lasers are fired from the back seat of the front car, with the target naturally being the eyes of the driver in the back seat.
Xu Zheng personally participated in the simulation. He was driving the car behind and wore double-layered glasses. Sure enough, after the technical policeman from the car in front adjusted the direction several times, he really hit Xu Zheng's face with the laser.
Because the direction is changed manually, there are always errors, so the simulation experiment can be done to this extent.
After it was over, technical police officer Lao Zhou opened the surveillance camera at the time of Ding Xin's car accident and pointed at a black Volvo 20 meters away from the right front of Ding Xin's Mercedes-Benz. "Xiao Xu, I analyzed it from the angle and distance because the laser distance is harmful. , the murderer should be this car."
This Volvo was not part of the investigation team before, mainly because the two cars were twenty meters apart, and there were four or five cars sandwiched between them.
Unexpectedly, the laser emitted by the laser transmitter was so far away. Xu Zheng turned his head and asked Long Chuchu to contact the Map Reconnaissance Corps and ask them to provide full route monitoring of the Volvo car.
But as soon as he finished speaking, he suddenly stopped Long Chuchu again, touching his chin with his hand, and he had the concept of Mohu in his mind.
Previously, Xu Zheng felt that the people behind the scenes were able to act in front of the special team step by step. If the members of the special team and several leaders who knew the news were excluded, then there were still two departments in the system that could detect Xu Zheng. their movements.
The first is the inspector. Although the inspector did not monitor the meeting room of the special team, they have ownership of several surveillance cameras on the floor where the meeting room is located.
The camera at the door, for example, is mainly used to monitor the clothing, conversation, and other bad behaviors of colleagues in the office building.
If the inspector uses these cameras, he can indeed notice Xu Zheng and the others coming and going.
In addition, the inspector also has the right to mobilize the driving recorder on the police car and the law enforcement recorder used for office operations. As long as he is willing, he can completely monitor Xu Zheng's mission route.
The other department is naturally the Pictorial Investigation Corps, or even the Municipal Bureau's Pictorial Investigation Detachment. These two departments can call the city's cameras. If someone has the authority, they can easily monitor Xu Zheng and the others.
In fact, the best and easiest thing is to monitor Xu Zheng's mobile phones. However, mobile phones used within the police force are basically not subject to surveillance, no matter how big the leader is.
Thinking of this, Xu Zheng was thinking about how he could obtain full surveillance of the Volvo at the time of the car accident without alerting the two units of the Provincial Pictorial Detective Corps and the Municipal Pictorial Detective Detachment.
It seems that we need to contact the traffic police in Xuanwu District and ask them to ask the city's picture investigation team for a copy of the surveillance of the vehicles one hundred meters in front and behind Ding Xin when he was involved in a car accident.
But if that's the case, another problem arises. The above are just his suspicions. It's impossible for the leader to be suspicious of a certain leader in the investigation and inspection because of his suspicions, right?
Moreover, if it really involves a certain leader, he has no authority to investigate them.
It had to be reported, and it had to be handed over to Gu Liangjun in the end, and it might even alert the director of the hall, Deputy Governor Zheng.
It's better to keep quiet for the time being and investigate this Volvo first. I just thought that if the person behind the scenes is really hiding among the detectives and inspectors, then he will have to do things more secretly.
Xu Zheng turned his head and looked at the two technical police officers, "Brother Zhou, Brother Li, I would like to thank you two for everything today, but there is one more thing I need to trouble you with. After you go back, no matter if anyone asks you, you You can’t tell the truth, and you have to pretend that you’re upset that things haven’t been resolved.”
Brother Zhou was very experienced. He didn't ask any more questions out of curiosity and just nodded, then left here with Xiao Li.
Xu Zheng saw the backs of them leaving and knew that what they did today might not be able to be hidden from anyone who was interested.
But even if he couldn't hide it, he could confuse the audience first. Thinking of this, he turned to Long Chuchu and said, "You stay in the conference room and ask about the task progress of each group. See when Zhou Fangben will come back. I'll go out."
Xu Zheng went directly to Peng Wanyou's office and notified Jian Xueqing and Liao Hai on the way. Since they were both at the provincial office, they arrived very quickly.
After listening to Xu Zheng's guess, the three leaders began to think deeply. Peng Wanyou took off his glasses and rubbed the corners of his sore eyes, "You know how to give us problems.
Individuals on the picture detective side have the authority to mobilize the city's cameras, and they also have to be cadres above the division level. Others have no authority to use the Sky Eye system to serve themselves privately.
Not to mention checking your whereabouts.
However, if someone really pretends to be doing something for personal gain and secretly uses permissions, the backend of the Sky Eye system can check it.
It's just a pity that the consequences of the Sky Eye System will require a meeting of the Standing Committee of the Provincial Department.
Therefore, if you just rely on guesswork, the leader will not agree to open the back door. "
Liao Hai smiled and said: "The Sky Eye system can't check the background, so just check this Volvo."
Well, the Criminal Investigation Corps happened to go to Xuanwu District to supervise a case. I asked my colleagues who were supervising to take the opportunity to ask the Xuanwu District Traffic Police Brigade for a copy of the surveillance video of key road sections in the district yesterday.
In this case, try to avoid the attention of detectives and inspectors. "
Anyone can check the owner information of the Volvo car, but it is important to know who was driving the car that day.
And whether Volvo's license plate is a set or not has not been determined.
Liao Hai did what he said and picked up his cell phone to make a call. Half an hour later, someone sent him several surveillance videos.
It was the surveillance video of the Volvo within five minutes before and after the accident.
Four people gathered around the computer and analyzed the driver of the car frame by frame.
What was unexpected was that the driver turned out to be a woman with long hair, wearing a hat and a mask. The surveillance cameras at several intersections did not capture the woman's face.
Apparently this was intentional on the part of the woman.
Unfortunately, the Volvo car window model is very good, and the people in the back seat were not found in these videos, including the laser transmitter.
Jian Xueqing stopped the video at the scene of the woman driving and asked Xu Zheng, "Can you draw a woman like this?"
"No." When Xu Zheng was watching the video just now, he discovered that this woman did not show any face in the video, including her face shape. The mask and hat basically blocked the camera's view.
Liao Hai sighed upon hearing this, "How about we go to the city bureau's map reconnaissance detachment to retrieve the driving route of this Volvo yesterday, and then find this car first."
Xu Zheng did not expect that the driver would be so cautious and only used the power of the reconnaissance detachment. If the people behind the scenes were really reconnaissance and inspectors, he would probably notice this.
But if you don't use a picture detective, you won't be able to investigate further.
Peng Wanyou saw the sad look on Xu Zheng's face, smiled and encouraged: "Didn't you say that when the car accident happened, there were four or five other cars between Ding Xin's Mercedes-Benz and the Volvo, then apply to the Detective Corps to investigate these few car.
If the person behind the scenes gets rid of the female driver and the person in the back seat again, it will also prove that your guess is correct. This person is most likely to be the leader of the detective or the inspector. "
There is no better way at the moment. Xu Zheng nodded reluctantly and prepared to follow the instructions of Director Peng, "Director Peng, why don't we wait until Zhou Fangben and the others come back and then apply to the Scout Corps. I was thinking that after I apply, I will get the news. Let's check a few other cars first to stall for time, just to show off.
Secretly, Zhou Fangben was asked to fully mobilize the Volvo and the female driver. "
Xu Zheng still made this arrangement secretly with Chen Cang, but he didn't know if he could hide the person behind the scenes.
At three o'clock in the afternoon, Zhou Fangben rushed back from Qingliu City without stopping. Xu Zheng immediately applied to the Scout Corps for access to all the surveillance videos of the four or five cars yesterday, including the Volvo.
The Graphic Investigation Corps, as a department that supports video surveillance of various police types, quickly sent relevant videos to the special team. Xu Zheng had a hundred police officers prepared by Liao Hai for him. After the video was sent over.
These 100 police officers became temporary detectives, focusing on investigating the female Volvo driver to see if they could find out the footage of her face and her final location.
The female driver of the Volvo was difficult to check, but the drivers of the other four cars were easy to check. Based on their license plates, the current locations of the four cars and the status of the drivers were quickly determined.
It can be seen at a glance that there is not much problem with this information. They are all private cars, and the owner and driver are the same person. However, the owner of the Volvo car is a man, but the driver is a woman, and she is also a woman who does not reveal her true face.
Obviously, this woman in this car is very suspicious.
But after Xu Zheng found out the owners and locations of the four cars, he took Long Chuchu directly to investigate one of them, and the other three were also investigated by members of the special team.
As for Zhou Fangben being kept by Xu Zheng, he planned to pretend that he had not found the Volvo. In fact, his main task was to find the female driver.
Unfortunately, after an hour of investigation, no footage of the woman's appearance was found in the surveillance video. However, with the help of the Sky Eye system, the current location of the car has been locked.
"Xiao Xu, the location of the Volvo has been locked by the Sky Eye system. The owner of the car, Ruan Zichen, has no criminal record, and his license plate is not a fake. The car is currently parked in the underground garage of his community. I will take people to Ruan Zichen's community now."
Xu Zheng had a suspicion, "Brother Zhou, first ask Ruan Zichen if he drove a Volvo out yesterday and if he knows the female driver?"
Zhou Fangben responded quickly, "You are saying that the car was stolen by the female driver yesterday and then drove back after completing the mission, is that right?"
"It should be like this. If that's the case, you can try to find useful fingerprints and hair tissue in the car." Xu Zheng didn't expect that the special team had obtained all the cameras on the Volvo drive, but none of the women were captured. Appearance, "Also, check the surveillance video of the underground parking lot in the community where the car owner lives and see if this woman's appearance is captured."
After the call between the two ended, Xu Zheng and Long Chuchu also arrived at their destination, Gulou Beihai Road, health and epidemic prevention station. The owner of the Volkswagen Passat worked here, and the car Xu Zheng wanted to check was parked in the parking lot of the epidemic prevention station.
Since no signs of foul play were found in this car, after completing the procedures and copying yesterday's driving recorder, Xu Zheng and the others headed back home.
Before he could return to the provincial office, Zhou Fangben's call came in. As soon as Xu Zheng answered the call, he heard good news.
"Xiao Xu, we didn't find the woman's face in the Volvo car owner's underground parking lot, but we visited several cars next to the Volvo and found that before the woman stole the car, the driving recorder of one car captured her profile."
It turned out that Ruan Zichen did not drive this Volvo yesterday. He went on a business trip early in the morning in a company car and only got home this morning. When his car was stolen yesterday, the car anti-theft app did not remind him for some reason.
If Zhou Fangben hadn't suddenly come to his door today, he really wouldn't have known that his car had been secretly driven out.
Zhou Fangben didn't get any useful information from Ruan Zichen, so he checked the surveillance of the community parking lot, and only found the female driver. Unfortunately, she was wearing a hat and mask the whole time, and her appearance was not photographed.
Fortunately, Zhou Fangben was experienced and checked several cars parked next to the Volvo yesterday. There was indeed a car whose driving recorder captured a frontal photo of a woman.
The female driver was still wearing a mask and hat, but this time her eyes and forehead were exposed.
Xu Zheng received the photo sent from Zhou Fangben, and with just one glance, he was sure he could draw the woman's appearance. He was happy and curious at the same time and asked: "Brother Zhou, what is this car for? Why didn't it turn off in the parking lot? "
"What else can he do?" Zhou Fang said without curiosity: "Either he is having an affair or he is preparing for an affair. Fortunately these days, everyone is witnessing it. This man's car is not turned off, otherwise his driving recorder can only monitor it for a few hours. That’s all.”
"In that case, come back quickly after checking the fingerprints and hair in the car." Xu Zheng got down to business, "I'm going to start making a simulation portrait now, and I think I'll be able to identify the female driver soon."
It was indeed very fast. Before Long Chuchu drove to the provincial office, Xu Zheng drew the appearance of the female driver. This woman had double eyelids cut on her eyes, her eyebrows were tattooed, her forehead was not wide, and her head was small, along her forehead and eyebrows. He guessed the shape of her face.
Then based on the height of the bulge at the top of the mask, Xu Zheng was 90% sure about the height of her nose, except for the mouth, which was difficult to determine.
After drawing a simulated portrait of the female driver, Xu Zheng took a photo with his mobile phone and sent it to Gu Jia, who was staying in the conference room. Soon, he found the woman in the system, Rong Teng, 26 years old, employed by the city bureau's special police detachment office. Auxiliary police...
When Xu Zheng received the news from Gu Jia, he was dumbfounded. Sure enough, the matter was getting more and more complicated. Could it be that the person behind the scenes was really a detective or inspector?
Rong Teng is from the special police detachment of the city bureau. Although she is an auxiliary police officer, she has worked for three years. However, she does not know whether her group was recruited through the security company or the city bureau itself.
