"The third screen in the first row, rewind to 6:45:37 AM, the seventh screen in the first row, rewind to 6:47:02."
Jiang Liu directs the policewoman who controls the surveillance video.
"The first screen in the second row, adjust the time to 6:49:31, and the second screen in the second row, adjust the time to 6:49:33."
"It's Xu Bo who lied!"
After giving such an order, Jiang Liu decisively gave such a conclusion. Not only did Niu Hung and Qian Dua who followed him get confused, but the few policemen beside him were also dazed.
"Hey, no, Jiang Liu, how did you see that Xu Bo was lying?"
Qian Duo leaned over to Jiang Liu and asked in a low voice. After getting along for a while, he found that Jiang Liu, just like him, had a little hobby of pretending to be X, but it also depends on the occasion when he pretends to be X.
Just what he did just now, does he really think he is a genius detective in a detective drama, a pair of eyes can monitor more than a dozen screens at the same time, and still remember every video in a short period of time
He's pretending to be X too much!
"Mr. Jiang, how did you come to the conclusion that Xu Bo was lying? Our colleagues in the bureau have already checked these dozens of video materials hundreds of times, and we have not found any evidence after repeated investigation and comparison, including the fact that you now let us Do these suspended pictures help this case?"
The police officers present are not familiar with these dozens of videos. They are almost skilled enough to recite the time when different scenes appear, so now Jiang Liu hastily came to such a conclusion, which is very absurd in their opinion, and also for those of them. Hard day mockery.
"The two videos in the first row recorded Liu Yanan and Xu Bo walking and cycling towards the crime scene respectively."
Jiang Liu pointed to the two videos that he first asked people to pause. He walked over to the policewoman, took the controller, and started playing from the time he ordered the pause, until they could no longer be captured in the video. Pause after the figure.
"It's a math problem."
As a top mathematician, Jiang Liu's mental arithmetic ability has long been terrifying to be comparable to a calculator. Almost at the same time as watching the video, he calculated the speed of the two's movements.
Liu Yanan walked very slowly, just as she told her. Generally speaking, unless there are special circumstances, an old man would not suddenly change the frequency of his actions in a short period of time. Based on her walking speed, Jiang Liu deduced that she was walking to the scene of the crime. The time of the location is 6:49:30, there may be a few seconds difference before and after.
As for Xu Bo, this kid is riding too fast. If he maintains the speed in the video, when he reaches the turning point at the time of the crime, the time should be around 6:49:30.
Of course, because both of them had a blind spot for a few minutes during their respective journeys, no one could be sure whether they had changed their speed within a few minutes of being in the blind spot. There are still some loopholes in Jiang Liu's algorithm.
It's just that Jiang Liu has two other pieces of evidence to prove that his inference is correct.
"The first screen in the second row magnifies the rotating cylinder in front of the hair salon, and the second screen magnifies the small round mirror in the upper right corner."
Before Jiang Liu's so-called math problems, everyone was confused, but they vaguely felt that Jiang Liu was still reliable, so after he gave the next instruction, they immediately cheered up and took a closer look at the two long parts. picture of.
"Nothing!"
Niu Hung was impatient. His eyes were tired when he saw these two pictures, and he couldn't see any evidence related to the case.
"Now the technology of the police station can display the reflective picture on this rotating barrel to the extent that it can be adjusted to me."
Jiang Liu looked at the technical policewoman and said.
Under the operation of the policewoman, the blurred reflective image soon became clearer, and at least the outline could be seen.
This is a video shot of a fly shop opposite the hair salon shop. The location of this shop is very close to the three-way intersection where the incident occurred, but the camera angle just avoided the incident location.
What's surprising is that the rotating barrel at the entrance of the hair salon, the reflection on the glass mirror after magnification and special treatment, actually restores the picture of Xu Bo passing by on a bicycle at that time.
In this framed picture, Xu Bo was riding a bicycle and was preparing to cross the three-way intersection, but at this time, there was no old lady who fell down on the ground.
"Look carefully at this location."
Jiang Liu clicked a certain position in the somewhat blurred and distorted reflection, "Look at this shape like a shoe toe, but it is blocked by the wall at the corner, if I guess correctly, this should be what Liu Yanan wore that day. Shoes, when Xu Bo was about to cross the three-way intersection, she should be coming from the other direction."
"And the state of Xu Bo displayed on the screen!"
Although the picture is blurry, Da Zishan can also make out an outline. At that time, Xu Bo, who was riding a bicycle, was just like the old lady said. Ringing the bell or braking when passing a fork in the road.
"And this picture."
Jiang Liu pointed to another picture that had been temporarily zoomed in. The reflection of this picture was much clearer than the previous one.
Some people like to hang a mirror at the door of their house. In Feng Shui, this is to prevent the robbery and the evil, and give the bad things that should have entered their home to other people's homes. The host in this video is obviously superstitious. There is a plastic round mirror with two dollars on the side of the street hanging on the door of the house, and it happens to be the mirror hanging on the nail, which reflects the terrified expression of the old lady who fell in a hurry to avoid the bicycle that suddenly rushed out.
Now it's clear, everything is just like what Liu Yanan said, she was walking normally, but a high school student on a bicycle who was driving too fast and didn't ring the bell suddenly sprang out from the other side of the turn, scaring her. Dodging, fell to the ground.
Although there was no direct collision, Xu Bo was responsible for the old lady's wrestling.
However, in order to evade responsibility, Xu Bo changed his tune after sending the old lady to the hospital, claiming that he saw the old man fall and did good deeds to send the old man to the hospital, but was blackmailed by the old man instead.
He didn't mention the circumstances at the time of the incident. He insisted that the old man had already fallen when he came over by bicycle. Taking advantage of his stillness as a minor, and the current public dissatisfaction with blackmailing the old man, he reversed right and wrong, and framed wrongs. an innocent old man.
Even after Liu Yanan's sullen death, neither he nor those indiscriminate public opinion promoters could be called innocent.
Of course, there are still those who did not give the old lady a clean slate, and they should also say sorry to the old lady.
At this time, everyone present was speechless.
Part of it is an apology to the innocent old lady, and part of it is an admiration for Jiang Liu.
The first point he pointed out was considered by the police, but because of the existence of a blind spot for a few minutes, it was not included in the scope of evidence, but then the two points of evidence were ignored by the police.
But maybe it's no wonder the police, because they are not like Jiang Liu, who have a brain whose reflexes and observations are almost developed to the extreme.
The police have also studied the reflection of the glass drum in the hair salon, which can be used as decisive evidence, but the reflection is affected by the light and the surrounding environment. At that time, they did not capture the picture from the glass drum that could restore the picture at that time. , with the naked eye, without any technical restoration, record the screen time that only lasts more than one second.
"At that time, Mrs. Liu took my hand and said she didn't deceive anyone."
The deputy captain of the traffic police brigade who was in charge of the case had a rough voice and clenched his fists tightly.
Why didn't he watch this video hundreds of times at that time, if he found out, wouldn't there be such a tragedy.
"And Uncle Xu, he said that his lover would never lie."
The young policeman on the side took off the police cap on his head and sat beside him in frustration.
The old man Xu mentioned in his mouth was Liu Yanan's husband. He suffered successively from losing his daughter, going to his wife, and being infatuated.
If it hadn't happened, if Xu Bo hadn't lied, and if the police could have been more forceful, would this old couple still be able to live happily in their old age, with firewood, rice, oil, salt, sauce, vinegar, and tea.
However, if something happens, there is no chance to regret it.
This is like a question that Jiang Liu sometimes thinks about, is justice belatedly still justice
However, he himself could not give himself an answer.
