Criminal Investigation Notes

Captain Wang scolded the two subordinates unhappily: "How did you do this work? If it weren't for Team Song, you wouldn't know that you had missed your work and stabbed such a big basket!"

Listening to what he said, Xiao Zeng, the responsible police officer on the side, saw Khan and came down.

Captain Wang spoke again: "I admit that we may be negligent in our work regarding whether the perpetrator is dead... But with regard to the car accident, we have all kinds of information and surveillance videos on hand. This is hard evidence. Maybe cheating?"

Song Wen flipped through the driver employment contract presented by that company. The employment date on it was half a year before the accident: "This contract is forged. They only temporarily found the terminally ill patient Chen Yanqiu early in the morning, probably to give the real cause of the accident. There is no need to go in the middle of the night for the so-called sending of clothes. Simply put, the results of the investigation presented in this car accident are all that the other party wants you to find out. There may be problems with the information you have. "

In a traffic accident, Chen Yanqiu was found to commit the crime, and a week later, Chen Yanqiu found a deceased roommate to replace him.If Chen Yanqiu had not been registered to die at that time, then he would face jail later.

Seeing Song Wen's words getting more and more bizarre, Li Yiheng seemed to be listening to the fantasy: "Song Team, I have been a traffic policeman for so many years, and I have never heard of such a thing."

Song Wen nodded and said, "I understand, it's not that you don't have rich work experience, but the criminals are too cunning."

Li Yiheng glanced at the Wang team again, and stammered: "Team Song, what you said...this thing is too bizarre and needs evidence..."

Team Wang came out again at this time to complete the game: "Team Song, maybe we did not do our job properly in the arrest process later to allow the perpetrator to escape, but you said Chen Yanqiu was not the real perpetrator of this traffic accident, but the crime. Yes, this matter is of another nature. After this traffic accident happened, our side has been actively investigating and coordinating. At that time, the other company compensated the victim's family with a total of 1.2 million yuan, and the victim's family also There is no objection to the handling of the matter. The case is now closed and filed in the bureau. If you want to investigate it again, I am afraid you have to find some actual evidence. Otherwise, we can't explain to several parties."

Song Wen thought for a while and asked: Did you find any abnormalities about the vehicle that caused the accident?"

Li Yiheng shook his head: "The driver escaped at the scene. When we followed the license plate number to find the company for inspection, it was already a few days later. The condition of the vehicle was consistent with the traces left at the scene of the accident. The Zotye car had Chen Yanqiu's fingerprints and some Hair marks. There are blood stains of the victim Zhao Youlan on the bottom of the car and tires."

"Two days are enough to pretend." Song Wen looked at Lu Siyu while speaking. Lu Siyu's face was pale, his eyebrows drooped, and he bit his fingers and said nothing.

He was thinking hard, what would he do if he handled this matter?

It is not difficult for him to imagine the situation at that time: Christmas Eve is over, Christmas is approaching, the business is closed, the dating couples have also dispersed, on the empty streets, there are various decorations hanging on the street, and they are falling off the road. With colored paper printed with Santa Claus.The air is cold. In this early morning, Zhao Youlan, a sanitation worker who got up early, started to work. She yawned and rode her cleaning car. At this moment, a car flashed by and blood flashed...

The driver of the crash was panicked, but then he calmed down. It was a small road with no pedestrians around.Instead of calling the police, he called someone for help...

Then those people temporarily found a scapegoat through Yu Niangniang's intermediary, and they called Chen Yanqiu.The body was seriously damaged, so it is difficult to judge the time of death...

But how should the matter of images be explained?Lu Siyu stopped thinking and looked at Song Wen.They just asked Zhuozhuo about the "part-time job", and it was hard to confess all this.If you want evidence, you must look at the monitoring at the time.

Song Wen also thought of this and raised his eyebrows and said: "This requires Captain Wang to ask us to retrieve the image data of the accident at that time. Let's go back and verify it."

There are many departments involved in this incident. It is estimated that there will be ridicules behind. They can’t do it on their behalf, and they don’t care how to deal with it here. But this traffic accident is related to their case and Chen Yanqiu’s death. Figure out everything that follows.

Captain Wang glared at Li Yiheng and Xiao Zeng, then turned his head and told several of his subordinates: "Isn't it time to cooperate with Team Song to find out the truth of the accident? The most important thing now is to restore the facts." He said, but winked.

There was a little policewoman who seemed to manage the video files, and whispered: "But...the king team, we need to transfer the files and apply for it... The director is not in the bureau today, this..."

Team Wang turned to look at Song Wen, with a trace of embarrassment on his face: "Oh, this, I forgot about the process in a hurry. Should you go back to Team Song? When the process is down, we will sort out the information for you. ?"

"Then let's take a look here, it's always okay, right?" Song Wen asked with a faint smile in not anxious.

The Wang team's expression froze: "Okay, you can move a chair for the Song team to sit down, let's look at the video data first."

The Wang team originally wanted to temporarily suppress the video data and investigate internally to see if there is a problem, but he couldn't stop Song Wen from checking the data here.

Song Wen replies to him: "Well, don't change the gear until you are sure that there is a problem." It seems that they must find some evidence from the video today, otherwise the case will probably be bored by the Transportation Bureau.

The men of the Wang team hurriedly retrieved the video recording 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 surveillance picture, a car is coming from the road, and the speed of the vehicle has not decreased. During the surveillance, the license plate number can be clearly seen, and it can be clearly seen that the driver is Chen Yanqiu.

Then the second video, immediately following the previous one, the camera is higher at this place, looking down, an empty road, a car driving at high speed, suddenly collided with the tricycle that Zhao Youlan was riding, and then, The vehicle hooked Zhao Youlan and disappeared from the screen.

In the third paragraph, Chen Yanqiu was still driving in the car. This time he shot a silhouette from a different angle. He drove out of the frame.

The video was played several times. Captain Wang pressed the pause and pointed to the screen and said: "The main evidence is these three segments. The time is completely coherent. We analyzed the screenshots. The driver was Chen Yanqiu, who was dragged. It is the deceased Zhao Youlan."

Song Wen had been watching with great concentration just now, and he turned his head and said: "Captain Wang, I feel that there are some problems in these videos."

Captain Wang asked: "Oh? Where is the problem?"

How sharp are Song Wen's eyes?After just reading it once, he found the problem: "Chen Yanqiu drove into someone, why didn't his expression change or slow down, so he just drove forward?" Seeing now, he became more and more sure that Chen Yanqiu was not real. Killed Zhao Youlan's murderer.

Captain Wang replied: "Then... maybe he didn't realize that he hit someone at first, right?"

"Then do you have any relevant images of the body found?" Song Wen asked again.

Captain Wang shook his head: "The corpse was dragged for a long time, and then it entered the blind spot of surveillance. There was no relevant video. Finally, the corpse was found on the side of the road."

Song Wen said again: "The first and third lines of the image can clearly see Chen Yanqiu, and even the first one can clearly see the license plate number. But the second one in the collision can not see Chen Yanqiu's face. I can’t see the license plate. I suspect that these are two similar cars."

Captain Wang shook his head and said: "But these monitoring times can be fully connected. We judged based on the distance between the second camera and the third camera and the driving speed. The time when the three video images appeared on each camera , In line with the situation of vehicles passing by."

Song Wen nodded: "It is true that surveillance can help us solve the case and restore the truth of the accident, but if we fully believe in the surveillance, we may be fooled by the image."

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

"I mean, these images are not real-time images. The monitoring time may have been changed, or edited and spliced." Song Wen said this, and the traffic police at the scene were in an uproar.

Captain Wang even called out directly, "This is impossible!"

Song Wendao: "Originally empty streets, at night, the light is not clear, it is easy to get confused. But by coincidence, I like painting, so my observation ability is better than ordinary people, so I can see There are some differences."

Captain Wang snorted, his attitude was obviously not good: "The Song team means that we are all blind and can't see the difference. Only you can tell?"

Song Wen said in a hurry, "I remember that last year, the road surveillance cameras in Nancheng had undergone a large-scale upgrade. The pixels should be high enough. To prove what I said, it is actually very simple. You take the first and third images Put it in the software and increase the contrast to maximum."

The female traffic policeman in charge of the information 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." Song Wen said, the policewoman pressed the play button.

On the projection of the big screen, the picture suddenly moved, and the naked eye could see that the position of the white dot on the picture had changed.Then, Chen Yanqiu appeared in the car.

"Huh..." Li Yi couldn't believe what he saw, rubbing his eyes.Captain Wang also showed an unbelievable expression.

Continue to play, similar situations appeared before and after the first and third videos.

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 trajectory. Some people cut the video, but These noises cannot be completely integrated. These noises are very small and do not stand out in the dark. Normally, you will not find anomalies, but when the pixels are high enough, after the contrast is increased, frame skipping occurs." Then he looked at the people from the Transportation Bureau, "In this way, even people who are not strong enough in observation can be distinguished with the naked eye."

Captain Wang's hand trembled: "This... how is this possible..."

But Song Wen's words are well-founded. Faced with such evidence, he can no longer say that there is no problem with the car accident.

Song Wen shrugged and said: "I think those people who pretended to be in a car accident first found a similar car, then the person who had committed the crime, drove the car again along the route, and then used hacker technology to hack into yours. The system replaced the related video, which caused your misjudgment."

In other words, perhaps the part-time job content that Chen Yanqiu received from there was to drive the car again along the route.He didn't notice the abnormality, and after getting the money, he discovered that a serious car accident occurred on the relevant road that day, and he somehow became an escape driver.

At that time, Zhang Rui happened to be seriously ill and died, and Chen Yanqiu figured out how to borrow the corpse to recover his soul and escaped.

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

"You mean, these images have been altered by others? How could our system be hacked? Maybe...the noise is just a coincidence..." Li Yiheng still refused to accept this fact, insisting.

Lu Siyu, who was 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 paragraph and The third paragraph is a similar model of a copycat Porsche, which is a Zotye car. The vehicle in these videos is not even one."

He added one more item and directly pressed the facts to death.

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

"Tires, handles, streamlines, and this exterior car decoration." Lu Siyu nodded the car on the screen.

The technician on the side hurriedly zoomed in and zoomed in on the picture, and you can see that in the second video, there is a black exterior trim on the body.

"The replacement car, that is, the car you tested was a copy of Porsche, called Zotye. Although the two models are almost the same, the details of Porsche cannot be imitated." Lu Siyu paused a little, "and This car decoration is a special order for the Porsche commemorative model, and the materials are all imported. In the other two videos, the car decoration of this part of the car is forged with similar black car decorations, and the reflectance and shape look obviously different ...So... please send us a copy of the registration information of this Porsche in this city."

The staff who requested the video zoomed in on the video and found that the shapes of the two car ornaments were slightly different.

Captain Wang looked at the two people in front of him as if looking at a monster: "How did you discover this?" The eyes of these two detectives, I'm afraid they are different from normal people, there are cameras hidden in them, right?

Lu Siyu said leisurely: "I understand this, just because I happened to have one of the same car." Then he found the photo from the phone and handed it over, "If you still don't believe it, you can ask a technical expert to appraise it. Download these videos."

Captain Wang finally realized that something was wrong at this time, frowned and turned around and said: "You quickly contact the person in charge of that company at the time and ask about the situation."

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

The king team said: "What about the legal person?"

The subordinate replied cowardly: "The phone cannot be reached, we are looking for other contact methods..." The other party's company is basically a shell company temporarily used to deal with the accident.

The Wang team took a deep breath: "Check all the information about this accident!"

The air solidified again for a while, and Song Wen coughed, "Well, the information we want..."

Captain Wang hurriedly said: "Well, where is the Song team, we thought that the problem was not too serious, so we said that we need to go through the process. Now it seems that the problem inside is very big. Naturally, we have to deal with special things. I will explain to the above. If the car in the accident is really a Porsche, this kind of luxury car, even in a city like Nancheng, there will not be too many cars. You can call out the list and investigate one by one to find the real murderer. The scope suddenly narrowed. Looking back, we will cooperate with you to find the real vehicle that caused the accident. We must find out who really killed Zhao Youlan." Captain Wang raised his hand and made a gesture. The little traffic policeman hurried to adjust more information.

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

However, Lu Siyu and Song Wen exchanged their eyes and said nothing for a while. This car accident topping case was not an ordinary topping case, but a premeditated, planned, well-planned topping case completed quickly.

This kind of dispatching, within a few hours, found the top packager, the disguised accident car, and even hacked into the traffic bureau in exchange for important information, and the shell company came forward and spent a lot of money to settle the matter. It is almost impossible. Possible tasks.

But unfortunately, such a thing happened.

Dingbao chooses terminally ill terminal patients who are dying. With the evidence of surveillance video, even Dingbao people cannot tell the whole truth. Once they die, everything will become secret and will be sealed forever.

So who was the real perpetrator and employer of the incident that night?

Has all this wishful thinking been broken by Chen Yanqiu's resurrection?

Is that employer related to Chen Yanqiu's death?

As the case was solved, more mysteries appeared.
