The three members of the Han family left.

On this cold winter night, their backs supporting each other seemed so lonely and helpless, anyone could see that the family was on the verge of destruction.

Liu Yanbo stood on the steps, watched, his eyes gradually became cold, and said, "Miss Gao, please trouble you, help me send them home safely." ”

After speaking, he didn't care whether Gao Wan'er wanted to or not, turned around and walked into the police station building.

In the police station.

The lights are bright, people come and go, and everything seems to be so busy and productive.

Liu Yanbo walked in, his face was very unfriendly, he almost wrote the four big words "don't approach the living" on his face, he didn't respond to the polite inquiry received by the front desk, and he didn't pay attention to Zhao Li, who met him again on the way, went straight to the second floor and broke into an office-

Office of the Deputy Director.

There was not only Pan Yuyi in the office, but also Zhou Ming and two other old policemen, who all looked at Liu Yanbo, who was very rude and broke in.

"Team, you guys go out first. ”

After Gao Wan'er said this, the two old policemen just looked at it a few times with some confusion, and then left silently, but Zhou Ming didn't leave, and asked with a frown: "Liu Yanbo, what are you doing here?"

"I'm going to watch all the surveillance footage of the Sleepless City Amusement Park after eight o'clock tonight, as well as all the road surveillance within a five-mile radius around it. Liu Yanbo walked straight to Pan Yuyi and said.

"We've seen the surveillance footage and we haven't found anything wrong, the child was lost outside the public toilet door of the amusement park, where there is no surveillance at all. Zhou Ming said: "Besides, our police force has rules and regulations, you are not a police officer, and you have no right to view those surveillance videos." ”

This time, Vice Captain Zhou really didn't want to deliberately target him Liu Yanbo.

Of course, regardless of whether Zhou Ming's refusal at this time was intentional or not, Liu Yanbo didn't care, let alone bothered, he just stared at Pan Yuyi-

I must watch this surveillance footage.

Pan Yuyi understood the meaning in his eyes, nodded and said, "Monitoring, I can show you, but you can only watch it here, you can't take it out, and you can't re-record it." ”

"Thank you. ”

Liu Yanbo thanked him, and then took advantage of the gap before the surveillance video was sent to call Yin Hanruo and say that he would not go back tonight.

The Sleepless City Amusement Park covers an area of hundreds of acres, and there are hundreds of cameras in the park, plus the surrounding road monitoring within a radius of five miles, there may be thousands, so many cameras, it is unlikely that you can watch them in one night, right?

Han Shuilan's mother and son arrived at the amusement park at about eight o'clock in the evening, and Han Chenxi was lost at half past nine in the evening, and there was a potentially dangerous period of nearly an hour and a half in between.

The police have already seen the video around the place of the incident at the time of the incident, and there is no gain, which means that there are no direct clues and evidence on the video, so Liu Yanbo can only watch all the surveillance videos in the middle of the hour and a half to see if he can find any clues.

The first thing he had to do was to determine one thing -

Regarding Han Chenxi's loss, was it premeditated or random.

If it is the former, there will inevitably be traces of the stalker in the video, and the scope can be narrowed down a lot;

If it's the latter, then it's really a bit of a needle in the bottom of the sea.

After the video was sent, Liu Yanbo first looked at the picture of Han Shuilan and her mother and son appearing.

There aren't many places they go, but an hour and a half is still a bit large, but fortunately, Liu Yanbo has a pair of special eyes, not only good eyesight, but also the perverted ability to remember and capture a moment.

The picture is five or six times faster than usual, like a marquee, dazzling, except for Liu Yanbo, who concentrates on not letting go of any moment, Pan Yuyi, who planned to follow and analyze together at the beginning, has already given up and started the errand of serving tea and pouring water.

The office became unusually quiet, and even Zhou Ming didn't say anything more.

Young Master Zhou is usually a bit willful and arrogant, but he is also a master who can distinguish priorities, and the more Liu Yanbo cares about Han Shuilan, it is also good news for him.

Half an hour later, Liu Yanbo watched all the surveillance videos with Han Shuilan's mother and son-

No signs of being followed have been found.

This is good news and bad news.

The advantage is that this shows that Han Chenxi's loss was not deliberately planned by someone, and it basically ruled out the direction of the enemy's actions, and the child's life safety factor was theoretically temporarily increased a lot;

The downside is that-

Liu Yanbo can only look for a needle in a haystack.

With hundreds of cameras and an hour or two of video, it's really not something that can be watched in a moment and a half.

But time doesn't wait for anyone.

According to the popular saying, the twenty-four hours after a person disappears is the golden time to find someone, but in Liu Yanbo's heart, the so-called golden time is only four hours at most-

In a man-made disappearance case, especially in such a crowded public place, once the suspect succeeds, he will naturally flee the scene according to the pre-planned route, but in order to avoid leaving without appearing abnormal and arousing the suspicion of others, they will generally stay in the area near the scene for a period of time before leaving completely, and the time taken here is usually within an hour;

After escaping the scene, there will be a first transfer, moving to a place that you think is temporarily safe to prepare for dressing up. The distance of this transfer will not be very long, but the distance will never be too short, the place 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 an extra half hour or so in the middle of the city to make sure that there is no tail;

After that, it's time for the real shift. The destination of this transfer of suspects will be their final place, and they will basically go out of the city, or if it is a coastal city, they will go to sea, and in order to prevent things from expanding to the point of full lockdown inspection, this must be done within two hours to complete this final transfer.

Four hours, a district bureau is applying at all levels, looking for traffic management, and even the military and other units to help...... After all these kinds of cumbersome procedures, it will probably take time to complete a complete lockdown.

These four hours are the golden time for the suspects to escape, that is, the golden time for Liu Yanbo to find them.

After these four hours, one second more is an exponential variable.

Two hours have passed since Han Chenxi was lost, and in Liu Yanbo's heart, there are only two hours left for him to have the golden time left.

Thinking of this, he couldn't help pinching his eyebrows a little sadly and worriedly, and finally, he got up and said, "Captain Pan, can you do me another favor and help me find a way to release all the camera footage together." ”
