Chapter 242: Looking for clues

The Han family left in three.
On this cold winter night, their backs holding each other seemed so lonely and helpless, anyone could tell that the family was on the verge of destruction.
Liu Yanbo stood on the steps and watched, a pair of eyes gradually became cold and said: "Miss Gao, please one thing, help me to send them home safely."
Finally, regardless of whether Gao Waner wanted it, he turned and walked into the police building.
In the police station.
Is brightly lit, people are coming and going, everything looks so busy and promising.
Liu Yanbo walked in, and his face was very unfriendly, so he almost wrote the four characters "Don't be close to others" on his face. , Went straight to the second floor and broke into an office—
Deputy Director's Office.
In the office, not only Pan Yuyi, but also Zhou Ming and two other old policemen, they all looked at Liu Yanbo, who had broken into it impolitely.
"Qi team, you go out first."
After Gao Waner said this, the two old policemen just looked at it with some doubt, and then left silently, but Zhou Ming did not leave, and frowned and asked, "Liu Yanbo, you What are you doing here? "
"I want to watch all the surveillance videos of the city amusement park after 8 o'clock tonight, and all the road monitoring within five miles of the surrounding area." Liu Yanbo walked straight to Pan Yuyi and said.
"We have watched the surveillance video and found no problems. The child was lost outside the public toilet door of the amusement park, and there was no surveillance at all." Zhou Ming said: "Besides, our police force has rules and regulations, You are not a police officer and have no right to view those surveillance videos. "
This time, Vice Captain Zhou really did not intentionally target him Liu Yanbo.
Of course, no matter whether Zhou Ming ’s refusal was intentional at this time, Liu Yanbo would not care, let alone make sense, he just stared at Pan Yuyi
I must watch this surveillance video.
Pan Yuyi understood the meaning in his eyes and nodded: "Monitoring, I can show you, but you can only watch it here, not take it out, let alone copy it."
"Thank you."
Liu Yan said thanks, then took a call to Yin Hanruo before the surveillance video had been sent, saying he would not go back tonight.
Night City Amusement Park covers an area of ​​hundreds of acres, and there are hundreds of cameras in the park. In addition, the surrounding roads within five miles of the road monitoring may be thousands. With so many cameras, it is unlikely to be finished in one night?
Han Shuilan's mother and son arrived at the amusement park around 8pm. Han Chenxi was lost at 9:30 pm. There was a potentially dangerous period of nearly an hour and a half.
The police have already watched the video around the place where the incident happened, and there is no gain, which means that there is no direct clue and evidence on the video, then Liu Yanbo can only monitor the video within the one and a half hours in the middle. Read it all to see if you can find any clues.
First of all, he must determine one thing
The loss of Han Chenxi is premeditated or random.
If it is the former, there will inevitably be traces of the tracker in the video, and the range can be reduced a lot;
If it is the latter, it really means a little haystack.
After the video was sent, Liu Yanbo first looked at the scene where Han Shuilan and her mother and son appeared.
They don't go much places, but the amount of one and a half hours is still a bit large. Fortunately, Liu Yanbo has a pair of special eyes, which not only has good eyesight, but also has the ability to memorize and capture the moment.
The picture is five or six times faster than usual. It is dazzling like a horse lantern. In addition to Liu Yanbo, who is not attentive to any moment, Pan Yuyi, who planned to watch and analyze it at the beginning, has already given up. The errand of serving tea and pouring water.
The office became very quiet, and even Zhou Ming didn't say anything.
Master Zhou Da is usually a bit capricious, but he is also a clear-cut priority. Besides, Liu Yanbo's performance is more concerned with Han Shuilan, which is also good news for him.
Half an hour later, Liu Yanbo watched all the surveillance videos where Han Shuilan's mother and son appeared
Found no signs of being followed.
This is good news and bad news.
The advantage is that this shows that Han Chenxi ’s loss was not intentionally planned, which basically ruled out the direction of the Qiu family, and the child ’s life safety factor has temporarily increased a lot in theory;
The disadvantage is that--
Liu Yanbo can only find a needle in a haystack.
Hundreds of thousands of cameras, an hour or two of video recording, this is really not finished in one and a half.
But time will not wait for others.
According to popular opinion, the twenty-four hours after a person's disappearance is the prime time to find someone, but in Liu Yanbo's heart, the so-called prime time is only four hours at most ----
In the case of man-made disappearances, especially in such public places where people come and go, once the suspects succeed, they will naturally escape the scene according to the route planned in advance, but in order to avoid leaving, it does not appear unusual and does not cause The suspicion of others, they generally stay in the area near the scene seemingly normal for a period of time before leaving completely, the time spent here is usually within an hour;
After escaping from the scene, there will be the first transfer, to a place that I think is temporarily safe for preparations such as dressing up. The distance of this transfer will not be very long, but the distance will never be too short. The venue will be selected in a relatively remote place. The drive is estimated to be about an hour, but half of the experienced kidnappers will spend half in the middle. The hour or so is a circle in the city, used to make sure there is no tail;
After, it is a real transfer. This time, the destination of the suspects will be their final place, and they will basically go out of the city. If it is a coastal city, they will go to the sea. In order to prevent the matter from expanding to the point of full closure inspection, this must be within two hours. It is possible to complete this final transfer only if it is done within.
Four hours is the time required for a bureau to pass through all levels of application, find traffic control, and even the military and other units to help ... After all kinds of cumbersome procedures, it can probably complete the time required to complete the closure of the city.
These four hours are the prime time for the suspects to escape, that is, Liu Yanbo's prime time to find them.
After these four hours, an extra second is a variable that increases exponentially.
Two hours have passed since Han Chenxi was lost. In Liu Yanbo's heart, there are only two hours left in his prime time.
Thinking of this, he could not help but squeeze his eyebrows with some sadness and worry. Finally, he got up and said: "Captain Pan, can you do me a favor, and find a way to put all the video recordings of the cameras together."
