Captain Wang reproached the two subordinates unhappily: "how do you do this work? If it wasn't for the song team, they wouldn't have known that you had made such a big mistake in your work before! "
Listen to his words, one side of the specific responsibility of the assistant police Xiao Zeng saw sweat came down.
Captain Wang said: "I admit that we may have been negligent in our work about whether the troublemaker died or not However, with regard to the traffic accident, we have all kinds of information and surveillance videos on hand. This is a mountain of irrefutable evidence. How can we fake it? "
Is all this wishful thinking broken by Chen Yanqiu's resurrection?
So who will be the real troublemaker and employer that night?
Dingbao chooses terminally ill patients who will die. With the evidence of surveillance video, even if Dingbao people retract their confession, they can't tell the whole truth. Once they die, everything will become a secret forever.
But that happened.
In a few hours, this kind of dispatching can find the top contractor, the accident car in disguise, and even sneak into the interior of the Transportation Bureau in exchange for important information. In addition, the shell subsidiary company will come forward and spend a lot of money to calm down the trouble. It is almost impossible to complete the task.
However, Lu Siyu and Song Wen exchanged their eyes for a moment. For a moment, they didn't say anything. The accident was not an ordinary case, but a premeditated, well planned and quickly completed case.
The office was quiet for a moment, and the traffic police of the accident department were busy preparing information.
Captain Wang said hastily: "well, if song team is not there, we thought the problem was not serious, so we said we should go through the process. Now it seems that the problem is very big, so we have to deal with special things. I will explain to the above. If the car involved in the accident is really a Porsche, there will not be too many such luxury cars, even in cities like Nancheng. You can call up the list and check one by one, so that the scope of finding the real culprit will be reduced. Later, we will cooperate with you to go to the old car yard to find the real accident vehicle. We must find out who actually killed Zhao Youlan. " Captain Wang said and raised his hand to make a gesture, and his little traffic police rushed to transfer more information.
The air froze again for a moment, and Song Wen coughed, "that, the information we want..."
Team Wang took a deep breath: "check all the information about the accident!"
The subordinate answered timidly: "we can't get through the phone. We are looking for other contact information..." The company of the other party is basically a subsidiary company temporarily used to deal with the accident.
"What about the legal person?" Wang said
After a while, a subordinate replied, "that company has been cancelled."
At this time, Captain Wang finally realized that something was wrong. He frowned and said, "please contact the person in charge of the company at that time and ask about the situation."
Lu Siyu said leisurely, "I know this just because I happened to have one of the same cars." Then he found the photo from his mobile phone and handed it to him. "If you can't believe it, you can find a technical expert to identify these videos."
Captain Wang looked at the two people in front of him like a monster: "how did you find this?" The eyes of these two criminal policemen are different from those of normal people. Are there cameras hidden in them?
The staff who retrieved the video enlarged the video and found that there were some subtle differences in the shapes of the two car decorations.
"The replacement car, that is, the car you tested at that time, is a fake of Porsche, called Zhongtai. Although the two models are almost the same, the details of Porsche can't be copied." Lu Siyu stopped for a moment, "and this car decoration is a special customization of the Porsche commemorative. The materials are all imported. In the other two videos, the car accessories in this part of the car are forged with similar black accessories, and the reflectance and shape are obviously different So Please get us a copy of the registration information of this kind of Porsche in our city. "
One side of the technical staff quickly enlarge the picture, you can see, in the second video, there is a black car body outside the decoration.
"The tires, the handlebars, the streamlines, and this exterior." Lu Siyu ordered the vehicles on the screen.
"Your judgment is based on..." Xiao Zeng asked.
He added a new one, which directly killed the facts.
Lu Siyu, rubbing his forehead, suddenly raised his head, sighed and interjected: "although the lighting is unknown, it can be seen from the video that the car in the second video is a Porsche. The first and third sections are similar to those of the Shanzhai Porsche, which is a Zhongtai car. The vehicles in these videos are not even one. "
"You mean these images have been altered? How could our system be hacked? Maybe Those noises are just coincidence... " Li Yiheng still refuses to accept this fact and insists.
"We feel that there are some problems in this traffic accident. Please cooperate with Captain Wang. All the information is submitted to us. " Song Wen said here, looking at team Wang, politely added, "it doesn't matter if we need to go through the process, we can wait."At that time, it happened that Zhang Rui was seriously ill and died. Chen Yanqiu came up with a way to revive his soul and escaped.
In other words, maybe the part-time job Chen Yanqiu received from there was to drive the car again along the route. He didn't notice the abnormality, but after he got the money, he found that there was a serious traffic accident on the relevant road that day, and he became a hit and run driver for no reason.
Song Wen shrugged his shoulders and said, "I think those who disguised the accident first found a similar car, then found the culprit, drove the car again along the route, then hacked into your system with hacker technology, replaced the relevant video, causing your misjudgment."
But Song Wen's words are well founded. In the face of such evidence, he can no longer say that there is no problem with the car accident.
Captain Wang's hand trembled: "this How could that be... "
Song Wen explained: "at night, there will be dust and flying insects in the air. These things form noise in front of the camera. The movement of the noise has a trajectory. Some people cut the video, but they can't completely fuse the noise. These noises are very small, and they are not prominent in the dark. Usually, you won't find any abnormalities, but when the pixels are high enough and the contrast is increased, frame skipping occurs. " Then he looked at the people in the Transportation Bureau, "so that even people who are not observant enough can distinguish them with their naked eyes."
Continue to play, the first and third video before and after a similar situation.
"Eh..." Li Yi couldn't believe what he saw and rubbed his eyes. Captain Wang also showed an incredible expression.
On the projection of the big screen, in the picture, suddenly move, the naked eye can see that the position of the white dot on the picture has changed. Later, Chen Yanqiu appeared in a car.
"Yes, that's it, and then play it." Song Wen said that the policewoman pressed the play button.
The female traffic police in charge of the information answered and started the operation as he said. After the contrast increased, the original dark image became darker, and some white spots appeared on the screen.
Song Wen was not impatient and said: "I remember last year, the road surveillance camera in Nancheng was upgraded in a large area. The pixels should be high enough. To prove what I said, it's actually very simple. You put the first and third images into the software, and then increase the contrast to the maximum."
Captain Wang snorted, his attitude was obviously not good: "the song team means that we are all blind, we can't see the difference, only you can see it?"
Song Wen said: "the street, which was originally empty, is at night, and the light is not clear, so it's easy to muddle through. But coincidentally, I like painting, so my observation is better than ordinary people, so I see some differences. "
Captain Wang called out directly, "it's impossible!"
"I mean, these images are not real-time images. The monitoring time may have been changed, or edited and stitched." Song Wen said this, the scene of the traffic police in an uproar.
"So What do you mean Captain Wang frowned.
Song Wen nodded: "it's true that monitoring can help us solve the case and restore the truth of the accident, but if we fully believe in monitoring, we may be cheated by the image."
Captain Wang shook his head and said: "but the monitoring time can be fully connected. We judge according to the distance between the second camera and the third camera and the driving speed. The time when the three videos appear in the images of each camera is in line with the situation of vehicles passing by. "
Song Wen added: "the first and third images can clearly see Chen Yanqiu, and even the first one can see the license plate number. But the second one of the collision, I can't see Chen Yanqiu's face clearly, and I can't see the license plate clearly. I suspect that these are two similar cars. "
Captain Wang shook his head: "the body was dragged for a long time, and then entered the blind area of monitoring. There was no relevant image. Finally, the body was found on the side of the road."
"Do you have any images of the body?" Song Wen asked again.
Captain Wang replied, "well Maybe he didn't find that he hit someone at first? "
How sharp are Song Wen's eyes? After only looking at it once, he found the problem: "Chen Yanqiu drove into a person. Why didn't her expression change or slow down and drive straight ahead?" Seeing now, he is more and more convinced that Chen Yanqiu is not the real killer who killed Zhao Youlan.
Captain Wang asked, "Oh? What's the problem? "
Song Wengang has been watching with great concentration. At this time, he turned his head and said, "Captain Wang, I feel that there are some problems in these videos."
After playing the video several times, Captain Wang pressed the pause, pointed to the screen and said, "the main evidence is that these three periods are completely consistent. We analyzed the screenshot. The driver is Chen Yanqiu, and the one who was dragged is Zhao Youlan."
In the third section, Chen Yanqiu is still driving. This time, he takes a profile from different angles. He drives out of the picture.
In the second video, the camera is high and overlooking. On the open road, a car passes at high speed and suddenly collides with Zhao Youlan's tricycle. Then, the car hooks Zhao Youlan and disappears from the picture.The main evidence is three videos taken by different cameras. In the first section, in the open intersection at night, in the monitoring screen, a car comes from the road, and the speed of the vehicle is not reduced. In the monitoring, you can clearly see the license plate number, and you can also see that the driver is Chen Yanqiu.
Wang team's staff quickly took out the video record of the day and played it on the monitor.
Song Wen said to him, "well, it's not urgent to transfer files when it's confirmed that there's a problem." It seems that they have to find some evidence from the video today, otherwise this case will be suffocated by the traffic bureau.
Team Wang originally wanted to temporarily suppress the video data and check internally to see if there was any problem, but he could not prevent Song Wen from accessing the data here.
Team Wang's expression was stiff: "well, you move chairs for team song, let's take a look at the video data first."
"Well, let's have a look here. Is that always OK?" Song Wen did not worry, asked with a smile.
Team Wang turned his head and looked at Song Wen, his face showing a trace of "Oh, this, I forgot the process in a hurry. Why don't you go back first? When the process comes down, we'll sort out the information for you. "
There was a policewoman who seemed to be in charge of video files and whispered: "but Team Wang, if you want to transfer files, you need to apply The director is not in the Bureau today. This... "
Captain Wang glared at Li Yiheng and Xiao Zeng, then turned his head and told several subordinates, "don't you cooperate with song team to find out the truth of the accident? The most important thing now is to restore the facts. " Then he winked.
There are many departments involved in this incident. It is estimated that there will be some wrangling in the future. They don't care how to deal with it. However, this traffic accident is related to their case and Chen Yanqiu's death, so we have to make clear what happened afterwards.
Song Wen also thought of this, pick eyebrow way: "this needs captain Wang let us access the accident video data at that time, we go back to check."
But how to explain the image? Lu Siyu stops thinking and looks at Song Wen. Now they just ask about Zhuo Zhuo and know about "working". It's hard for them to make a confession. If you want evidence, you have to look at the monitoring.
Then those people find a scapegoat through the intermediary of fish lady, and they call Chen Yanqiu. The body was badly damaged, so it's difficult to judge the time of death
The driver of the crash panicked, but then he calmed down. It was a deserted path with no passers-by around. Instead of calling the police, he called someone else for help
All kinds of Christmas decorations are hanging on the street, and it's hard to imagine the situation when the Christmas decorations are still hanging on the street. The air is cold. In this early morning, Zhao Youlan, an early sanitation worker, starts to work. She yawns and rides her cleaning car. Just then, a car light flashes and blood light suddenly appears
He was trying to figure out what he would do if he dealt with it?
"Two days is enough to disguise." Song Wen talks and looks at Lu Siyu. Lu Siyu's face is white and his eyebrows are lowered. He bites his fingers and doesn't speak for a moment.
Li Yiheng shook his head: "the driver escaped from the scene. It was a few days before we found the company we belonged to for inspection. The condition of the vehicle was consistent with the traces left at the scene of the accident. There are Chen Yanqiu's fingerprints and some hair marks on the Zhongtai car. There are bloodstains of the victim Zhao Youlan under the car and on the tires. "
Song Wen thought about it and then asked, "did you find anything unusual about the accident vehicle?"
At this time, team Wang came out again and said, "team song, maybe we didn't do our work well in the arresting process, so that the perpetrators could escape. But you said that Chen Yanqiu was not the real perpetrator of the traffic accident, but the culprit. This is another personality. After the traffic accident, we have been actively investigating and coordinating. At that time, the other party's company compensated 1.2 million for the families of the victims, and the families of the victims had no objection to the handling of the matter. It's all sealed up in the Bureau. If you want to investigate again, I'm afraid you have to find some actual evidence. Otherwise, we can't explain to several parties. "
Li Yiheng took another look at team Wang and stammered: "team song, what you said It's so strange that we need evidence... "
Song Wen nodded and said, "I understand that it's not that you don't have rich working experience, but that the criminals are too cunning."
Watching Song Wen speak more and more strange, Li Yiheng seems to be listening to the Arabian Nights: "Song team, I have been a traffic policeman for so many years, I have never heard of such a thing."
In a traffic accident, she found Chen Yanqiu to take the blame. A week later, she found her dead roommate to replace her. If Chen Yanqiu had not been registered to die at that time, then he would have faced the disaster of imprisonment.
Song Wen looked at the driver's employment contract presented by the company. The date on the contract was half a year before the accident: "this contract was forged. They found the terminally ill patient Chen Yanqiu only in the early morning of the same day. Maybe it was to answer the charge for the real troublemaker. There was no need to send clothes in the middle of the night, In short, the survey results presented in this accident are all what the other party wants you to find out. There may be problems with the information you have. "Does that employer have anything to do with Chen Yanqiu's death?
With the investigation of the case, there are more mysteries.
The author has something to say: there is an English play about video forgery called "truth capture". If you are interested, you can find it. The technology in it is more high-end. Net, net,...:
Please report us if you find any errors so we can fix it asap!
Captain Wang reproached the two subordinates unhappily: "how do you do this work? If it wasn't for the song team, they wouldn't have known that you had made such a big mistake in your work before! "
Listen to his words, one side of the specific responsibility of the assistant police Xiao Zeng saw sweat came down.
Captain Wang said: "I admit that we may have been negligent in our work about whether the troublemaker died or not However, with regard to the traffic accident, we have all kinds of information and surveillance videos on hand. This is a mountain of irrefutable evidence. How can we fake it? "
Is all this wishful thinking broken by Chen Yanqiu's resurrection?
So who will be the real troublemaker and employer that night?
Dingbao chooses terminally ill patients who will die. With the evidence of surveillance video, even if Dingbao people retract their confession, they can't tell the whole truth. Once they die, everything will become a secret forever.

In a few hours, this kind of dispatching can find the top contractor, the accident car in disguise, and even sneak into the interior of the Transportation Bureau in exchange for important information. In addition, the shell subsidiary company will come forward and spend a lot of money to calm down the trouble. It is almost impossible to complete the task. However, Lu Siyu and Song Wen exchanged their eyes for a moment. For a moment, they didn't say anything. The accident was not an ordinary case, but a premeditated, well planned and quickly completed case. The office was quiet for a moment, and the traffic police of the accident department were busy preparing information. Captain Wang said hastily: "well, if song team is not there, we thought the problem was not serious, so we said we should go through the process. Now it seems that the problem is very big, so we have to deal with special things. I will explain to the above. If the car involved in the accident is really a Porsche, there will not be too many such luxury cars, even in cities like Nancheng. You can call up the list and check one by one, so that the scope of finding the real culprit will be reduced. Later, we will cooperate with you to go to the old car yard to find the real accident vehicle. We must find out who actually killed Zhao Youlan. " Captain Wang said and raised his hand to make a gesture, and his little traffic police rushed to transfer more information. The air froze again for a moment, and Song Wen coughed, "that, the information we want..." Team Wang took a deep breath: "check all the information about the accident!" The subordinate answered timidly: "we can't get through the phone. We are looking for other contact information..." The company of the other party is basically a subsidiary company temporarily used to deal with the accident. "What about the legal person?" Wang said After a while, a subordinate replied, "that company has been cancelled." At this time, Captain Wang finally realized that something was wrong. He frowned and said, "please contact the person in charge of the company at that time and ask about the situation." Lu Siyu said leisurely, "I know this just because I happened to have one of the same cars." Then he found the photo from his mobile phone and handed it to him. "If you can't believe it, you can find a technical expert to identify these videos." Captain Wang looked at the two people in front of him like a monster: "how did you find this?" The eyes of these two criminal policemen are different from those of normal people. Are there cameras hidden in them? The staff who retrieved the video enlarged the video and found that there were some subtle differences in the shapes of the two car decorations. "The replacement car, that is, the car you tested at that time, is a fake of Porsche, called Zhongtai. Although the two models are almost the same, the details of Porsche can't be copied." Lu Siyu stopped for a moment, "and this car decoration is a special customization of the Porsche commemorative. The materials are all imported. In the other two videos, the car accessories in this part of the car are forged with similar black accessories, and the reflectance and shape are obviously different So Please get us a copy of the registration information of this kind of Porsche in our city. " One side of the technical staff quickly enlarge the picture, you can see, in the second video, there is a black car body outside the decoration. "The tires, the handlebars, the streamlines, and this exterior." Lu Siyu ordered the vehicles on the screen. "Your judgment is based on..." Xiao Zeng asked. He added a new one, which directly killed the facts. Lu Siyu, rubbing his forehead, suddenly raised his head, sighed and interjected: "although the lighting is unknown, it can be seen from the video that the car in the second video is a Porsche. The first and third sections are similar to those of the Shanzhai Porsche, which is a Zhongtai car. The vehicles in these videos are not even one. " "You mean these images have been altered? How could our system be hacked? Maybe Those noises are just coincidence... " Li Yiheng still refuses to accept this fact and insists. "We feel that there are some problems in this traffic accident. Please cooperate with Captain Wang. All the information is submitted to us. " Song Wen said here, looking at team Wang, politely added, "it doesn't matter if we need to go through the process, we can wait."At that time, it happened that Zhang Rui was seriously ill and died. Chen Yanqiu came up with a way to revive his soul and escaped. In other words, maybe the part-time job Chen Yanqiu received from there was to drive the car again along the route. He didn't notice the abnormality, but after he got the money, he found that there was a serious traffic accident on the relevant road that day, and he became a hit and run driver for no reason. Song Wen shrugged his shoulders and said, "I think those who disguised the accident first found a similar car, then found the culprit, drove the car again along the route, then hacked into your system with hacker technology, replaced the relevant video, causing your misjudgment." But Song Wen's words are well founded. In the face of such evidence, he can no longer say that there is no problem with the car accident. Captain Wang's hand trembled: "this How could that be... " Song Wen explained: "at night, there will be dust and flying insects in the air. These things form noise in front of the camera. The movement of the noise has a trajectory. Some people cut the video, but they can't completely fuse the noise. These noises are very small, and they are not prominent in the dark. Usually, you won't find any abnormalities, but when the pixels are high enough and the contrast is increased, frame skipping occurs. " Then he looked at the people in the Transportation Bureau, "so that even people who are not observant enough can distinguish them with their naked eyes." Continue to play, the first and third video before and after a similar situation. "Eh..." Li Yi couldn't believe what he saw and rubbed his eyes. Captain Wang also showed an incredible expression. On the projection of the big screen, in the picture, suddenly move, the naked eye can see that the position of the white dot on the picture has changed. Later, Chen Yanqiu appeared in a car. "Yes, that's it, and then play it." Song Wen said that the policewoman pressed the play button. The female traffic police in charge of the information answered and started the operation as he said. After the contrast increased, the original dark image became darker, and some white spots appeared on the screen. Song Wen was not impatient and said: "I remember last year, the road surveillance camera in Nancheng was upgraded in a large area. The pixels should be high enough. To prove what I said, it's actually very simple. You put the first and third images into the software, and then increase the contrast to the maximum." Captain Wang snorted, his attitude was obviously not good: "the song team means that we are all blind, we can't see the difference, only you can see it?" Song Wen said: "the street, which was originally empty, is at night, and the light is not clear, so it's easy to muddle through. But coincidentally, I like painting, so my observation is better than ordinary people, so I see some differences. " Captain Wang called out directly, "it's impossible!" "I mean, these images are not real-time images. The monitoring time may have been changed, or edited and stitched." Song Wen said this, the scene of the traffic police in an uproar. "So What do you mean Captain Wang frowned. Song Wen nodded: "it's true that monitoring can help us solve the case and restore the truth of the accident, but if we fully believe in monitoring, we may be cheated by the image." Captain Wang shook his head and said: "but the monitoring time can be fully connected. We judge according to the distance between the second camera and the third camera and the driving speed. The time when the three videos appear in the images of each camera is in line with the situation of vehicles passing by. " Song Wen added: "the first and third images can clearly see Chen Yanqiu, and even the first one can see the license plate number. But the second one of the collision, I can't see Chen Yanqiu's face clearly, and I can't see the license plate clearly. I suspect that these are two similar cars. " Captain Wang shook his head: "the body was dragged for a long time, and then entered the blind area of monitoring. There was no relevant image. Finally, the body was found on the side of the road." "Do you have any images of the body?" Song Wen asked again. Captain Wang replied, "well Maybe he didn't find that he hit someone at first? " How sharp are Song Wen's eyes? After only looking at it once, he found the problem: "Chen Yanqiu drove into a person. Why didn't her expression change or slow down and drive straight ahead?" Seeing now, he is more and more convinced that Chen Yanqiu is not the real killer who killed Zhao Youlan. Captain Wang asked, "Oh? What's the problem? " Song Wengang has been watching with great concentration. At this time, he turned his head and said, "Captain Wang, I feel that there are some problems in these videos." After playing the video several times, Captain Wang pressed the pause, pointed to the screen and said, "the main evidence is that these three periods are completely consistent. We analyzed the screenshot. The driver is Chen Yanqiu, and the one who was dragged is Zhao Youlan." In the third section, Chen Yanqiu is still driving. This time, he takes a profile from different angles. He drives out of the picture. In the second video, the camera is high and overlooking. On the open road, a car passes at high speed and suddenly collides with Zhao Youlan's tricycle. Then, the car hooks Zhao Youlan and disappears from the picture.The main evidence is three videos taken by different cameras. In the first section, in the open intersection at night, in the monitoring screen, a car comes from the road, and the speed of the vehicle is not reduced. In the monitoring, you can clearly see the license plate number, and you can also see that the driver is Chen Yanqiu. Wang team's staff quickly took out the video record of the day and played it on the monitor. Song Wen said to him, "well, it's not urgent to transfer files when it's confirmed that there's a problem." It seems that they have to find some evidence from the video today, otherwise this case will be suffocated by the traffic bureau. Team Wang originally wanted to temporarily suppress the video data and check internally to see if there was any problem, but he could not prevent Song Wen from accessing the data here. Team Wang's expression was stiff: "well, you move chairs for team song, let's take a look at the video data first." "Well, let's have a look here. Is that always OK?" Song Wen did not worry, asked with a smile. Team Wang turned his head and looked at Song Wen, his face showing a trace of "Oh, this, I forgot the process in a hurry. Why don't you go back first? When the process comes down, we'll sort out the information for you. " There was a policewoman who seemed to be in charge of video files and whispered: "but Team Wang, if you want to transfer files, you need to apply The director is not in the Bureau today. This... " Captain Wang glared at Li Yiheng and Xiao Zeng, then turned his head and told several subordinates, "don't you cooperate with song team to find out the truth of the accident? The most important thing now is to restore the facts. " Then he winked. There are many departments involved in this incident. It is estimated that there will be some wrangling in the future. They don't care how to deal with it. However, this traffic accident is related to their case and Chen Yanqiu's death, so we have to make clear what happened afterwards. Song Wen also thought of this, pick eyebrow way: "this needs captain Wang let us access the accident video data at that time, we go back to check." But how to explain the image? Lu Siyu stops thinking and looks at Song Wen. Now they just ask about Zhuo Zhuo and know about "working". It's hard for them to make a confession. If you want evidence, you have to look at the monitoring. Then those people find a scapegoat through the intermediary of fish lady, and they call Chen Yanqiu. The body was badly damaged, so it's difficult to judge the time of death The driver of the crash panicked, but then he calmed down. It was a deserted path with no passers-by around. Instead of calling the police, he called someone else for help All kinds of Christmas decorations are hanging on the street, and it's hard to imagine the situation when the Christmas decorations are still hanging on the street. The air is cold. In this early morning, Zhao Youlan, an early sanitation worker, starts to work. She yawns and rides her cleaning car. Just then, a car light flashes and blood light suddenly appears He was trying to figure out what he would do if he dealt with it? "Two days is enough to disguise." Song Wen talks and looks at Lu Siyu. Lu Siyu's face is white and his eyebrows are lowered. He bites his fingers and doesn't speak for a moment. Li Yiheng shook his head: "the driver escaped from the scene. It was a few days before we found the company we belonged to for inspection. The condition of the vehicle was consistent with the traces left at the scene of the accident. There are Chen Yanqiu's fingerprints and some hair marks on the Zhongtai car. There are bloodstains of the victim Zhao Youlan under the car and on the tires. " Song Wen thought about it and then asked, "did you find anything unusual about the accident vehicle?" At this time, team Wang came out again and said, "team song, maybe we didn't do our work well in the arresting process, so that the perpetrators could escape. But you said that Chen Yanqiu was not the real perpetrator of the traffic accident, but the culprit. This is another personality. After the traffic accident, we have been actively investigating and coordinating. At that time, the other party's company compensated 1.2 million for the families of the victims, and the families of the victims had no objection to the handling of the matter. It's all sealed up in the Bureau. If you want to investigate again, I'm afraid you have to find some actual evidence. Otherwise, we can't explain to several parties. " Li Yiheng took another look at team Wang and stammered: "team song, what you said It's so strange that we need evidence... " Song Wen nodded and said, "I understand that it's not that you don't have rich working experience, but that the criminals are too cunning." Watching Song Wen speak more and more strange, Li Yiheng seems to be listening to the Arabian Nights: "Song team, I have been a traffic policeman for so many years, I have never heard of such a thing." In a traffic accident, she found Chen Yanqiu to take the blame. A week later, she found her dead roommate to replace her. If Chen Yanqiu had not been registered to die at that time, then he would have faced the disaster of imprisonment. Song Wen looked at the driver's employment contract presented by the company. The date on the contract was half a year before the accident: "this contract was forged. They found the terminally ill patient Chen Yanqiu only in the early morning of the same day. Maybe it was to answer the charge for the real troublemaker. There was no need to send clothes in the middle of the night, In short, the survey results presented in this accident are all what the other party wants you to find out. There may be problems with the information you have. "Does that employer have anything to do with Chen Yanqiu's death? With the investigation of the case, there are more mysteries. The author has something to say: there is an English play about video forgery called "truth capture". If you are interested, you can find it. The technology in it is more high-end. Net, net,...:
