Laser experts are not so easy to find, especially experts related to weapons, Xu Zheng thought about it, or borrowed two technical policemen from the technical detective, and prepared to simulate the route of the burning Ding Xin laser on the spot.

Let's find out which car it is.

The laser emitter used by the murderer emitted a laser that exceeded the range specified by the toy factory and was a lethal weapon, and Xu Zheng and the others could not find this kind of laser weapon for a while.

So they just bought a few toy laser emitters, like small flashlights, which Xu Zheng played with when he was a child.

The simulation is actually very simple, that is, the front and rear cars are set up with an intelligent assistance system at the same time, the speed is set to 80 yards, and then the laser is fired in the front and back seats, and the target is naturally the eyes of the driver in the back seat.

Xu Zheng personally participated in the simulation, he drove the car behind him, wearing double-layer glasses, and sure enough, after the technical police in front of him adjusted the direction a few more times, he really hit Xu Zheng in the face.

Because it is a manual change of direction, there is always an error, so the simulation experiment can be done to this extent.

After the end, the technical police officer Lao Zhou turned on the monitoring at the time of Ding Xin's car accident and pointed to a black Volvo twenty meters away from the right front of Ding Xin's Mercedes-Benz, "Xiao Xu, I analyzed the angle and distance, because of the laser distance injury, the murderer should be this car." ”

The Volvo had not been part of the task force 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 this laser emitter was so far, Xu Zheng turned his head sideways and asked Long Chuchu to contact the Graphic Investigation Corps and ask them to provide the whole route monitoring of the Volvo car.

But as soon as he finished speaking, he suddenly stopped Long Chuchu again, touched his chin with his hand, and had a concept of a lake in his heart.

Before, Xu Zheng felt that the people behind the scenes could pinch the point and act in front of the special group step by step, if the members of the special group and several leaders who knew the news were excluded, then there were still two departments in the system that could detect Xu Zheng's movements.

One is the Inspector, although the Inspector does not monitor the conference room of the special group, they have the ownership of several surveillance cameras on the floor where the conference room is located.

Like the camera at the door, it mainly monitors the bad behaviors of colleagues in the office building, such as dressing, talking, and playing.

If the Inspector had made use of the cameras, he would indeed have been able to notice Xu Zheng and them going in and out.

In addition, the inspector also has the right to mobilize the tachograph on the police car and the law enforcement recorder used to handle the police, as long as there is a heart, it is completely possible to monitor the route of Xu Zheng's mission.

The other department is naturally the Graphic Investigation Corps, and even the Municipal Bureau Graphic Investigation Detachment, these two departments can call the city's cameras, and if someone has permission, they can casually monitor Xu Zheng's traces.

In fact, the best and most trouble-free thing is to monitor Xu Zheng's mobile phone, but the mobile phone used within the police force basically has no possibility of being monitored, no matter how big the leader is.

Thinking of this, Xu Zheng was thinking about how he could not alarm the two units of the Provincial Graphic Investigation Corps and the Municipal Graphic Investigation Detachment to get the whole process monitoring of this Volvo at the time of the car accident.

It seems that they have to contact the traffic police in Xuanwu District and ask them to ask the city graphic investigation team for a copy of the monitoring of the vehicles 100 meters before and after Ding Xin's car accident on the grounds of handling the eucalyptus.

It's just that in this case, another problem has arisen, the above are just his suspicions, and the leader can't be suspicious of a certain leader of the detective and inspector because of his suspicions, right?

Besides, if a certain leader is really involved, he has no authority to investigate people at all.

has to be reported, and in the end it has to be handed over to Gu Liangjun, and even if it doesn't matter, it will alarm the hall chief, Vice Provincial Zheng.

It's better to keep quiet for the time being, check this Volvo first, but I just think that if the person behind the scenes is really hidden in the detectives and inspectors, then he has to do things more secretively.

Xu Zheng turned his head and looked at the two technical policemen, "Brother Zhou, Brother Li, thank you two for today's matter, but there is still one thing to trouble you, that is, after you go back, no matter whether anyone asks you or not, you can't tell the truth, and you have to pretend that things haven't been done and are annoyed." ”

Brother Zhou is experienced, he didn't ask more because of curiosity, just nodded, and left here with Xiao Li.

Xu Zheng saw the back of them leaving, and knew that what they did today might not be able to hide from those who had a heart.

But even if you can't hide it, you can confuse the public first, thinking of this, he turned his head sideways and said to Long Chuchu: "You stay in the conference room to ask about the task progress of each group, and see when Zhou Fangben will come back, and I will go out." ”

Xu Zheng went directly to Peng Wanyou's office, and informed Jian Xueqing and Liao Hai on the way, because they were both in the provincial hall, the two came quickly.

After listening to Xu Zheng's speculation, the three leaders began to ponder together, Peng Wanyou took off his glasses and rubbed the corners of his sour eyes, "You kid knows how to give us a problem."

Individuals on the map detective side have the authority to mobilize the city's cameras, and they also have cadres at or above the department level, and others have no authority to privately use the Tianyan system to serve themselves.

Not to mention checking your whereabouts.

However, if someone really pretends to be public and secretly uses authority, the background of the Tianyan system can be checked.

It's just a pity that the consequences of the Tianyan system have to open a meeting of the Standing Committee of the Provincial Department.

So, if you only guess, the leader will not agree to open the back door. ”

Liao Hai said with a smile: "The background of the Tianyan system can't be checked, so just check this Volvo."

In this way, the Criminal Investigation Corps happened to go to Xuanwu District to supervise a eucalyptus, and I asked my colleagues who went to supervise it to take the opportunity to ask the Xuanwu District Traffic Police Brigade for a surveillance video of yesterday's key road sections in the whole district.

In this case, it is not possible to avoid the attention of the detective and the inspector as much as possible. ”

Anyone can check the owner information of the Volvo car, but it is important to know who was driving that day.

And whether Volvo's license plate is a deck or not, these have not been determined.

Liao Hai said just do it, directly picked up his mobile phone to make a call, and after half an hour, someone sent him several surveillance videos.

It was the Volvo's surveillance footage in the five minutes before and after the accident.

Four people gathered around the computer, analyzing the driver of the car frame by frame.

Unexpectedly, the driver turned out to be a woman, with long hair, a hat and a mask, and the surveillance at several intersections did not capture the woman's face.

Apparently this is an intentional act on the part of the woman.

Unfortunately, the Volvo window model is very powerful, and the footage does not reveal the person in the back seat, including the laser emitter.

Jian Xueqing stopped the video at the shot of the woman driving, and asked Xu Zheng sideways, "Can you draw the appearance of a woman like this?" ”

"I can't." When Xu Zheng watched the video just now, he found that the woman did not show a trace of her face in the video, including the face shape, and the mask and hat basically covered the camera's view.

Liao Hai sighed when he heard this, "Why don't we go to the graphic investigation detachment of the city bureau and get the driving route of this Volvo yesterday, and find this car first." ”

Xu Zheng didn't expect the driver to be so cautious, just using the power of the graphic reconnaissance detachment, if the person behind the scenes was really a detective and inspector, this would probably be detected by him.

But if you don't use the graphic detective, there is no way to check the eucalyptus.

Peng Wanyou saw Xu Zheng's face full of sadness, and encouraged with a smile: "Didn't you say that when the car accident happened, there were still four or five Mercedes-Benz cars in Ding Xin's car and Volvo, then apply to the Graphic Investigation Team to check these cars."

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 conjecture is right from the side, and this person is likely to be the leader of the detective or the inspector. ”

There is no better way at the moment, Xu Zheng nodded a little reluctantly, ready to follow Peng Hall's instructions, "Peng Hall, or wait for Zhou Fangben and them to come back and then apply to the Graphic Investigation Corps, I was thinking, after the application, we will get the news, let's check a few other cars first, delay the time, and make a show."

Secretly asked Zhou Fangben to do his best to adjust the Chavolvo and the female driver. ”

Xu Zheng's arrangement is still secret, but he doesn't know if he can hide it from the people behind the scenes.

At three o'clock in the afternoon, Zhou Fangben rushed back from Qingliu City without stopping, and Xu Zheng immediately applied to the Graphic Investigation Corps to access the four or five cars yesterday, including all the surveillance footage of Volvo.

As a department that supports the video surveillance of various police types, the graphic investigation corps soon sent relevant videos to the special group, Xu Zheng has a hundred police forces prepared for him by Liao Hai, and the video is transmitted.

These 100 police forces have become temporary investigators, focusing on investigating the female driver of Volvo to see if they can find the picture of her face and the final destination.

The female driver of the Volvo is not easy to check, but the drivers of the other four cars are easy to check, and according to their license plates, the current location of the four cars and the driver's situation are quickly locked.

These information can be seen at a glance that there is not much problem, they are all private cars, the owner and the driver are the same person, and the Volvo owner information is a man, but the driver is a woman, or a woman who does not show her true face.

It is clear that this woman is very suspicious of this car.

But after Xu Zheng found out the owners and locations of the four cars, he directly took Long Chuchu to investigate one of them, and the other three were also members of the special team to investigate.

As for Zhou Fangben being left behind by Xu Zheng, he pretended to find this Volvo unless, in fact, his main task was to find this female driver.

It's a pity that after an hour of investigation, no footage of the woman's appearance was found in the surveillance video, but with the help of the Sky Eye system, the current location of the car has been locked.

"Xiao Xu, Volvo's location has been locked by the Tianyan system, the owner Ruan Zichen, no criminal record, and his license plate is not a deck, the car is now parked in the underground garage of his community, I will take people to Ruan Zichen Community now."

Xu Zheng had a suspicion, "Brother Zhou, you first ask Ruan Zichen if he drove a Volvo out yesterday, and if he knew a female driver?" ”

Zhou Fangben reacted quickly, "You mean that the car was stolen by the female driver yesterday, and then drove back after the mission, isn't that so?" ”

"It should be like this, and if that's the case, you can see if you can find useful fingerprints and hair tissue in the car." Xu Zheng didn't expect that the special team got all the cameras of the Volvo ride, but they didn't capture the woman's appearance, "Also, you check the surveillance video of the underground parking lot in the community where the owner is located to see if you have captured the woman's appearance." ”

At the end of the call between the two, Xu Zheng and Long Chuchu also rushed to their destination, Gulou Beihai Road, the health and epidemic prevention station, the owner of the Volkswagen Passat went to work here, and the car that Xu Zheng was going to check was parked in the parking lot of the epidemic prevention station.

Because the car found no signs of eucalyptus in the surveillance, so, after completing the procedure and copying yesterday's dashcam, Xu Zheng and the others went home.

Before he returned to the provincial hall, Zhou Fangben's phone called, and Xu Zheng heard a good news as soon as he connected it.

"Xiao Xu, we didn't find the woman's appearance in the Volvo owner's underground parking lot, but we visited several cars next to the Volvo and found that before the woman stole the car, the dashcam of a car photographed her side face."

It turned out that Ruan Zichen did not drive this Volvo yesterday, he was on a business trip early in the morning in the company's car, and he only arrived home this morning, and 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 the door today, he really didn't know 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 parking lot in the community, but found the female driver, but unfortunately she was wearing a hat and mask the whole time, and she didn't take pictures of her appearance.

Fortunately, Zhou Fangben has a lot of experience, and he checked a few cars parked next to Volvo yesterday, and there was really a car dashcam that took a frontal photo of the woman.

The female driver is still wearing a mask and a hat, but this one shows her eyes and forehead.

Xu Zheng received the photo from Zhou Fangben, and with just one glance, he was sure that he could draw the appearance of this woman, and asked curiously at the same time: "Brother Zhou, what is this car for, why is it not turned off in the parking lot?" ”

"What else can you do" Zhou Fangben said curiously: "It's either cheating or preparing for cheating, but fortunately, it was witnessed by the whole people in this year, this person's car didn't turn off, otherwise his dash cam could only monitor it for a few hours." ”

"In that case, you guys should come back quickly after checking the fingerprints and hair in the car." Xu Zheng got down to business, "I'll start making a simulated portrait here, and it is estimated that I will soon be able to lock the identity of this female driver." ”

It was indeed very fast, before Long Chuchu drove to the provincial hall, Xu Zheng drew the appearance of the female driver, the woman's double eyelids were cut, the eyebrows were tattooed, the forehead was not wide, the head shape was small, and her face shape was speculated along the forehead and eyebrows.

and then guess the height of her nose according to the height of the bulge above the mask, except for the mouth that is not easy to determine, the others Xu Zheng is ninety percent sure.

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 stayed in the conference room, and soon, he found this woman in the system, Rong Teng, 26 years old, a service auxiliary police officer hired by the special police detachment office of the city bureau...

When Xu Zheng received the news from Gu Jia, he was directly dumbfounded, sure enough, this matter is getting more and more complicated, is the person behind the scenes really the person in the detective or the inspector?

Rong Teng is a member of the special police detachment of the city bureau, although she is a service auxiliary policeman, she has also worked for three years, but I don't know if she was recruited by the security company or by the city bureau itself.
