Criminal Investigation Notes

Captain Wang reproached the two subordinates with displeasure: "how do you do this work? If the song team didn't come here, I didn't know that you had made such a big mistake in your work before! "

Listen to his words, a side of the specific responsibility of the small police have seen sweat down.

Captain Wang said again: "I admit that our work has been negligent in the matter of whether the perpetrator is dead or not However, with regard to the traffic accident, we have all kinds of information and surveillance videos on hand, which are irrefutable evidence. How can it be falsified? "

Song Wen looked through the driver's employment contract presented by the company. The employment date on it was half a year before the accident: "this contract is forged. They found Chen Yanqiu, a terminally ill patient, in the early morning of the same day. It may be to make a confession to the real troublemaker, such as sending clothes or so, There is no need to go in the middle of the night. Simply put, the investigation results presented by the accident are all what the other party wants you to find out. There may be problems with the information you have. "

In a traffic accident, Chen Yanqiu was asked to take his place. A week later, Chen Yanqiu found a roommate who died of illness to replace him. If Chen Yanqiu had not been registered to die, then he would have been in prison.

Looking at Song Wen saying 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."

Song Wen nodded his head and said, "I understand that it is not that you are not experienced in work, but that the criminals are too cunning."

Li Yiheng took another look at the Wang team and stammered, "Song team, what you said It's so weird. We need evidence... "

At this time, team Wang came out to play the game again: "Song team, maybe we didn't do a good job in the following arrest process, so that the perpetrators could escape. But you said that Chen Yanqiu was not the real troublemaker of the traffic accident, but he was the one who committed the crime. This matter is another personality. After the traffic accident, we have been actively investigating and coordinating. At that time, the company of the other party compensated the victim's family a total of 1.2 million yuan, and the victim's family 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'll have to find some practical evidence. Otherwise, we can't explain to several parties. "

Song Wen thought about it and asked: did you find anything unusual about the vehicle that caused the accident

Li Yiheng shook his head: "the driver escaped from the scene. It was a few days since we found the company we belonged to according to the license plate number. The vehicle condition is consistent with the traces left at the scene of the accident. There are fingerprints and some hair traces of Chen Yanqiu on Zhongtai car. There was the blood of the victim Zhao Youlan on the bottom of the car and on the tires. "

"Two days, enough time for camouflage." Song Wen talks and looks at Lu Si Yu, whose face is white and droops his eyebrows. For a moment, he bites his finger and doesn't speak.

He was trying to think, what would he do if he had dealt with it?

It was not difficult for him to imagine what it would be like at that time: Christmas Eve was over, Christmas was coming, businesses were closed, and dating couples were scattered. On the empty street, decorations were still hanging on the street, and colored paper with Santa Claus on it was dropped. The air is cold. In such an early morning, Zhao Youlan, an early sanitation worker, starts to work. She yawns and rides her own cleaning car. At this time, a car light flashes and blood light suddenly appears

The driver of the crash panicked, but then he calmed down. It was a small, inaccessible road with no passers-by. Instead of calling the police, he called someone else for help

Later, those people found a scapegoat through the intermediary of the fish lady. They called Chen Yanqiu. The body is badly damaged, so it is difficult to determine the time of death

But how to explain the image? Lu Si Yu stopped thinking and looked at Song Wen. Now they only ask about Zhuzhuo and know about "working". It is difficult to make a confession. If you want evidence, you have to look at the monitoring.

Song Wen also thought of this point and raised his eyebrows and said, "this requires captain Wang to let us take down the video data of the accident at that time, and we will go back and verify it."

There are many departments involved in this incident. It is estimated that there are some disputes behind. They don't need to take over their responsibilities and do not care about how to deal with it. However, this traffic accident is related to their case and Chen Yanqiu's death, so we can't help but understand everything that follows.

Captain Wang glared at Li Yiheng and Xiaozeng, and then turned his head and told his subordinates: "don't you cooperate with song team to find out the truth of the accident? Now the first thing is to restore the facts. " He winked as he spoke.

There was a little policewoman who seemed to be managing the video files and whispered, "but Team Wang, we need to transfer out the files and apply The director is not in the Bureau today

Wang team turned to look at Song Wen, his face showed a trace of: "Oh, this, I forgot the process in a hurry. Do you want song team to go back first? When the process is finished, we will arrange the data for you? "

"Well, let's have a look here. Is it always possible?" Song Wen was not in a hurry and asked with a smile.

Wang team expression a stiff: "well, you move a chair for song team, we first look at the video data."Wang team originally wanted to temporarily suppress the video data, internal check to see if there is a problem, but he can't stop Song Wen from reading the information here.

Song Wen returned to him: "well, it's not urgent to adjust the file until there is a problem." It seems that they must find some evidence from the images today, otherwise the case will be stuck in the traffic bureau.

Wang's men quickly retrieved the video record of the day and played it on the monitor.

The main evidence is three videos taken by different cameras. In the first section, at an open intersection at night, in the monitoring picture, a car comes from the road, and the vehicle speed is not reduced. During the monitoring, you can clearly see the license plate number, and you can also see clearly that the driver is Chen Yanqiu.

In the second video, the camera is high and overlooking. On the open road, a car drives by at high speed and suddenly collides with the tricycle Zhao Youlan is riding. Then, the vehicle disappears from the picture with 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.

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 have analyzed the screenshots. The driver is Chen Yanqiu, and the one dragged is Zhao Youlan."

Song Wengang has been watching with great concentration. At this time, he turned his head and said, "Captain Wang, I feel there is something wrong with these videos."

Captain Wang asked, "Oh? What's the problem? "

How sharp is Song Wen's eyes? After only looking at it once, he found out the problem: "Chen Yanqiu hit someone in his car. Why didn't Chen Yanqiu's expression change or slow down, just drive straight ahead?" See now, he more and more confirm that Chen Yanqiu is not the real murderer who killed Zhao Youlan.

Captain Wang replied, "well Maybe he didn't find out he hit someone at first, did he

"Do you have any images of the body?" Song Wen asked again.

Captain Wang shook his head: "the body was dragged for a long time, and then entered the surveillance blind area. There was no relevant image. Finally, the body was found on the roadside."

Song Wen also said: "the first and third images can clearly see Chen Yanqiu, and even the first one can see the license plate number. But for the second one, Chen Yanqiu's face and license plate can't be seen clearly. I suspect that these are two similar cars. "

Captain Wang shook his head and said, "but the monitoring time can be fully connected. We judge it 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 consistent with the situation of vehicles passing by. "

Song Wen nodded: "it is true that monitoring can help us solve the case and restore the truth of the accident, but if we fully believe in the monitoring, it is likely to be deceived by the images."

"So What do you mean? " Captain Wang frowned.

"What I mean is that these images are not real-time images, and the monitoring time may have been changed or, in other words, edited and spliced." Song Wen said this sentence, the scene of the traffic police in an uproar.

Captain Wang called out directly, "it's impossible!"

Song Wen said: "it's night when the streets are empty, and the light is not clear, so it's easy to get confused. But coincidentally, I like to draw, so my observation is better than that of ordinary people. Therefore, I see some differences in them

Captain Wang snorted, and his attitude was obviously bad: "the song team means that we are all blind and can't see the difference. Only you can see it?"

Song Wen said: "I remember last year, the road monitoring cameras in Nancheng were upgraded in a large area, and the pixels should be high enough. To prove what I said, it's very simple. You put the first and third images into the software, and then increase the contrast to the maximum."

The female traffic police officer in charge of the data responded. As he said, the operation started. After the contrast increased, the originally dark image became darker, and some white spots appeared on the screen.

"Yes, that's it. Then play it." Song Wen said that the policewoman pressed the play button.

On the projection of the big screen, in the picture, suddenly move, the naked eye can see that the position of the white point on the picture has changed. Later, Chen Yanqiu appeared in a car.

"Eh..." Li Yi couldn't believe what he saw and rubbed his eyes. Captain Wang also showed an incredible expression.

Continue to play, the first and third video before and after a similar situation.

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 these noise points has a motion track. 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, so we can't find any abnormality at ordinary times. However, when the pixels are high enough and the contrast is increased, there will be frame skipping phenomenon. " Then he looked at the people at the Transportation Bureau, "so that even those who are not observant enough can be identified with the naked eye."Captain Wang's hand trembled: "this How could this be... "

However, 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 accident.

Song Wen shrugged: "I think those who camouflage the accident first found a similar car, and then found the culprit, drove the car again along the route, and then hacked into your system, replaced the relevant video, causing your misjudgment."

That is to say, 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 section that day, and he somehow became a hit and run driver.

At that time, it happened that Zhang Rui was seriously ill and died. Chen Yanqiu came up with a way to revive his soul by borrowing a corpse and escaped.

"We feel that there are some problems in this traffic accident. We also ask captain Wang to cooperate more. All the information is submitted to us. " Song Wen said here, looking at the Wang team, politely added, "it doesn't matter if we need to go through the process. We can wait."

"You mean the images have been altered? How could our system be hacked? Maybe That noise is just a coincidence... " Li Yiheng still refuses to accept this fact, and he is adamant.

Lu Si Yu, rubbing his forehead, suddenly raised his head, sighed and interposed: "although the light 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 versions of the counterfeit Porsche, which is a Zhongtai car. The vehicles in these videos are not even one. "

He added another one, and it just killed the facts.

"Your judgment is based on..." Xiao Zeng asked.

"Tires, handles, streamlines, and this exterior trim." Lu Si points to the vehicles on the screen.

One side of the technician quickly enlarged the picture and then zoomed in. You can see that in the second video, there is a black exterior decoration on the body.

"The replacement car, that is to say, the car you tested at that time was a counterfeit model of Porsche, called Zhongtai. Although the two models are almost the same, the details of Porsche can not be copied." The Luxi language pauses for a moment, "and this decoration is specially customized for the commemorative model of Porsche, and the materials are all imported. In the other two videos, the decoration of this part of the car is forged with similar black decoration, and the reflectance and shape look obviously different So Please send us a copy of the registration information of the city's Porsche. "

The staff who took the video enlarged the video and found that there were some subtle differences in the shape of the two car decorations.

Captain Wang looked at the two people in front of him like a monster: "how did you find out?" The eyes of these two policemen are different from those of normal people. Are there cameras hidden in them?

Lu Si Yu said leisurely, "I know these things just because I happen to have one of the same models." If you have a few photos in the video, you can find out from the video

At this time, Captain Wang finally realized that there was something wrong with the situation. He frowned and turned around and said, "please contact the person in charge of that company at that time and ask about the situation."

After a while, a subordinate replied, "that company has been cancelled."

Wang said, "what about the legal person?"

Some of the subordinates timidly replied: "the phone can't get through, we are looking for other contact information..." The company of the other party is basically a shell company used to deal with the accident temporarily.

Wang took a deep breath: "check all the information about this accident!"

The air froze for a while, and Song Wen coughed, "that, the information we want..."

Captain Wang quickly said, "well, where is song team? We thought that the problem was not too serious, so we said we should go through the process. Now it seems that there is a big problem in it. Naturally, we need special services. I will explain it to the above. If the car causing the accident is really a Porsche, there will not be many such luxury cars even in cities like Nancheng. You can call up the list and check them one by one, so that the scope of finding the real culprit will be narrowed down. Later, we will cooperate with you to go to the old garage to find the real accident vehicle. We must find out who really killed Zhao Youlan. " Wang captain said raised his hand to make a gesture, under the small traffic police quickly to transfer more information.

The office was quiet for a while, and the traffic police in the accident department were busy preparing materials.

However, Lu Siyu and Song Wen exchanged their eyes and did not speak for a moment. The top package case of this traffic accident was not an ordinary top package case, but a premeditated, well planned and quickly completed top package case.

In a few hours, this kind of dispatch can find the top contractor, find the disguised accident car, and even sneak into the interior of the traffic bureau, in exchange for important information, and some shell subsidiary companies come forward and spend a lot of money to make peace, which is almost impossible to complete.

But it happened.Top bag chooses terminally ill patients who are going to die. With the evidence of surveillance video, even if the top bag person retracts his confession, it can't tell the whole truth. Once they die, everything will become a secret, forever sealed.

So who was the real troublemaker that night and who was the employer?

Is all this wishful thinking broken by Chen Yanqiu?

Does that employer have anything to do with Chen Yanqiu's death?

With the detection of the case, there are more mysteries.
