A few minutes later, Lee returned to the lounge and agreed to Han Bin's request.

Han Bin and Bao Xing were taken to the monitoring room.

The bank control room is about twenty or thirty square meters, and the entire wall has been made into a monitoring screen, and there is a staff member watching the monitoring.

Each sub-screen is a corner of the bank, different cameras shoot different angles, Han Bin has also checked the surveillance in many places, and no one can match the degree of rigor.

Li Jinying took the two to the monitoring room and left, leaving only Han Bin, Bao Xing, and the bank staff member in charge of checking the surveillance.

Han Bin was not very familiar with the situation here, and the number of surveillances was too much, and he looked a little dazzled. With the help of the bank staff named Xiao Wu, he figured out the location of the surveillance camera.

Theoretically, there is indeed no blind spot in the monitoring of this bank, and every position can be monitored by cameras.

Han Bin investigated the surveillance on August 2, first checked the route of Li Shiwei in and out of the bank, and put forward all the surveillance that could be filmed on him, and other surveillance was temporarily excluded.

There are nine cameras that have captured Li Shiwei's movements, and it is not a small task to compare them one by one.

Han Bin divided the video into three stages, the first stage Li Shiwei came to the bank, the second stage withdrew money, and the third stage left.

The first camera to capture Li Shiwei was outside the bank, a Jinbei car was parked in the parking space at the entrance of the bank, a man in a police uniform walked down, and then Li Shiwei and Lin Zhengyi walked down, and a police officer should have stayed in the car.

Next, the police officers who got out of the car stood at the door of the bank to observe the surrounding situation, only Li Shiwei and Lin Zhengyi entered the bank, and after communicating with the lobby manager, the two were directly invited to the lounge, checked the identity information and began to load money.

Han Bin checked it several times, and there was no problem with this process, there were three bank staff members who were responsible for withdrawing money, loading money, and checking it, and it was carried out under the supervision of Li Shiwei and Lin Zhengyi, and the suspicion of the bank staff could basically be ruled out.

After watching this stage of monitoring, it was already noon, Bao Xing went out to buy two boxed lunches, and after lunch, the two continued to check the monitoring.

The money is loaded in the VIP room, which can be said to be free of dead ends throughout the whole process, and can basically rule out abnormalities.

After that, it's time to take the money and leave.

At this stage, Li Shiwei and Lin Zhengyi separated, Lin Zhengyi walked out of the bank first, walked to the door of the bank and said a few words to the police.

Han Bin roughly figured out the reason for Lin Zhengyi's departure with his lips.

After withdrawing the money, Li Shiwei asked him to notify the police officers at the police station to check the surrounding situation, and if there was nothing abnormal outside, Li Shiwei would go out with a box containing cash.

Originally, this situation was normal, and people couldn't find fault with it.

However, not long after Lin Zhengyi left the lounge, Li Shiwei also pushed the box out of the lounge, and refused to be escorted by the bank staff.

Li Shiwei pushed the box through the bank lobby and went to the bank door to meet Lin Zhengyi and the police officers, during which Li Shiwei had been alone with the cash box.

Han Bin checked the monitoring during this period of time several times, and did not intuitively see any problems, as if he was leaving naturally after withdrawing the money.

If it weren't for the fact that Li Shiwei was a major suspect, there would be no problem with Li Shiwei just looking at this video, and there would be nothing particularly abnormal.

After all, he just pushed the box from the VIP room to the door of the bank, and in the eyes of ordinary people, there is no safer place than the bank.

But Han Bin checked several cameras and compared the monitoring content from all angles and found a problem, Li Shiwei would pass by a counter when passing through the hall, this counter is about more than a meter high, there is no staff inside, and it is specially used for customers to fill in information.

There is also a huge circular load-bearing stone pillar diagonally opposite the counter.

A monitoring blind spot is formed between the counter and the stone pillar, this monitoring blind corner is only about one meter high, and people will still be photographed by the monitoring in the direction of the counter when they pass by, but when the box passes by, it happens to be blocked by the counter, and the stone pillar blocks the monitoring on the other side.

As he passed through this journey, Han Bin couldn't see the box for a moment, which was very short, maybe only about a second.

Han Bin saw the box again and found that the distance between the position of the box and Li Shiwei's right foot had become larger, and this change was not very obvious from the surveillance, but Han Bin's observation power was far beyond ordinary people, and he could still see the abnormality.

Han Bin repeatedly checked this surveillance video and came to a bold speculation that there was originally a box between the counter and the cylinder, which was exactly the same as the box held by Li Shiwei.

If this speculation is correct, then Li Shiwei should have an accomplice in the bank, and this accomplice placed a fake box in advance, and after a successful exchange, he will take away the box containing cash.

Han Bin continued to check the surveillance and found a man not far from the counter, this man was wearing a cap and mask, a blue T-shirt on the upper body, and a pair of casual trousers on the lower body, sitting on a stool not far from the counter, looking like he was waiting for business.

Han Bin took a closer look, the man had been looking around since he entered the bank, and after Lin Zhengyi and Li Shiwei appeared, the man had an obvious downward movement, but his gaze kept following the two.

Han Bin focused on the man, and checked all the surveillance of his entry and exit from the bank.

The man arrived at the bank at about 9:10, and when he entered the bank, he was also pushing a suitcase, which was similar in size to the box containing money, but there was a blue sleeve on the outside, and the color of the box itself could not be seen clearly.

After the man entered the bank, he pushed the box to the counter, and then sat on a stool not far away, during which the man only stood up twice, once when Lin Zhengyi left the lobby and once when Li Shiwei left the lobby.

Han Bin felt that the other party standing up was probably changing the box cover.

Not long after Li Shiwei left, the man also pushed the box and left, during which he did not handle any business and did not consult the bank staff.

Moreover, the man consciously avoided the camera, adding a cap and a mask, and his face was almost invisible, obviously a little thief-minded.

At this time, the case has become clear, and the man who pushed the box is most likely Li Shiwei's accomplice.

Han Bin continued to check the man's whereabouts, and from the surveillance at the bank gate, it could be seen that the man walked out of the bank to a black Volvo car, put the cash box in the trunk of the car, and then drove the car away.

Han Bin zoomed in on the surveillance video and wrote down Volvo's license plate number: Lu B343HD.

Then he took out his phone and made a call.

"Hey, Team Han. Li Qin's voice rang on the phone.

"How's your investigation going?"

"I asked the technical department to check the mobile phone numbers in the names of Li Shiwei and Wang Zhixiang, and did not find that the two had direct contact, nor did they find that the two sides had a common contact. Li Qin paused and proposed, "Do you want to expand the scope of inquiries to see if the mobile phone numbers of their families are connected?" ”

"Sister Li, let's put the investigation of mobile phone communication for the time being, you go and check a license plate number Lu B343HD. ”

Li Qin wrote down the license plate and asked, "Team Han, is there anything wrong with this license plate number?"

"Through the investigation of the bank's surveillance, we found that Li Shiwei may have changed the boxes containing cash in the bank, and one of the men suspected to be his accomplices was driving this black Volvo car. ”

"I see, I'm going to look it up. ”

As long as the suspicious man is found, the whereabouts of the stolen money can be found.
