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

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

The bank monitoring room is about 20 to 30 square meters, and the entire wall is made into a monitoring screen. A staff member is watching the monitoring.

Each sub-screen is a corner of the bank. Different cameras shoot from 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 responsible for checking the monitoring.

Han Bin is not very familiar with the situation here, and the number of monitoring is too much, which looks a little dazzling. With the help of the bank staff named Xiao Wu, he figured out the location of the surveillance shooting.

Theoretically speaking, the bank's surveillance is indeed without blind spots, and every location can be monitored by cameras.

Han Bin investigated the surveillance on August 2 and first checked Li Shiwei's route to and from the bank, and brought up all surveillance that could capture him, and temporarily excluded other surveillance.

There are nine cameras that captured Li Shiwei's trajectory, and the workload of comparing them one by one is not small.

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

Li Shiwei’s camera was the first to be photographed outside the bank. A Jinbei car was parked in a parking space at the bank’s entrance. A man in a police uniform walked down. Then Li Shiwei and Lin Zhengyi walked down. A police officer should have stayed in the car.

Next, the police officer who got off stood at the door of the bank to observe the surrounding situation. Only Li Shiwei and Lin Zhengyi entered the bank. After communicating with the lobby manager, the two were directly invited to the lounge, checked their identity information and began to load money.

Han Bin checked it several times and found that there was no problem with this process. There were three bank staff responsible for withdrawing money, loading money, and checking. They were carried out under the supervision of Li Shiwei and Lin Zhengyi. The suspicion of bank staff can basically be eliminated. .

After watching the monitoring at this stage, it was noon. Bao Xing went out and bought two boxes of lunch. After lunch, the two continued to check the monitoring.

The money loading is carried out in the VIP room. It can be said that there are no blind spots throughout the process, and the abnormality can basically be eliminated.

After that is the stage of leaving with money.

At this stage, Li Shiwei and Lin Zhengyi separated. Lin Zhengyi left the bank first and walked to the door of the bank to talk to the police officer.

Han Bin used his lips to roughly figure out why Lin Zhengyi left.

After withdrawing the money, Li Shiwei asked him to notify the police officer at the police station to check the surrounding situation. If there is no abnormality outside, Li Shiwei will go out with the cash box.

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

However, shortly 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 lobby of the bank and met with Lin Zhengyi and the police at the door of the bank. During this time, 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 it was a natural departure after withdrawing the money.

If it is not determined that Li Shiwei has a major suspicion, there is no problem with Li Shiwei just watching this video, and there is no special abnormality.

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

However, Han Bin checked several cameras and compared the monitoring content from various angles and found a problem. When Li Shiwei passed the lobby, he would pass by a counter. This counter was about one meter high and there was no staff inside. It was specially used for customers to fill in the information. of.

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

A dead corner of surveillance is formed between the counter and the stone pillars. This dead corner of surveillance is only about one meter high. When people pass by, they will still be captured by the surveillance in the direction of the counter, but when the box passes by, it happens to be blocked by the counter. The stone pillar obstructed the surveillance on the other side.

During this journey, Han Bin couldn't see the box for a moment. This time was very short, maybe only about one second.

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

Han Bin repeatedly checked this surveillance video and came up with a bold conjecture. There was originally a box placed between the counter and the column. This box was exactly the same as the one held by Li Shiwei. When passing through the blind spot of surveillance, Li Shiwei took it. He left the box prepared in advance, leaving the box with cash.

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

Han Bin continued to check the surveillance and found a man not far from the counter. This man was wearing a peaked cap and a mask. The man was wearing a blue T-shirt on his upper body and a pair of casual trousers on his lower body. He was sitting next to a stool not far from the counter. It seems to be waiting for business.

Han Bin observed carefully. After entering the bank, the man had been looking around. After Lin Zhengyi and Li Shiwei appeared, the man made an obvious bowing movement, but his eyes followed the two.

Han Bin focused the surveillance on this man, and checked all the surveillance of him entering and leaving the bank.

This man arrived at the bank at about nine ten ten. He also pushed a suitcase when he entered the bank. This suitcase was similar in size to the suitcase with money, except that there was a blue suitcase outside, so the color of the suitcase was not clear.

After entering the bank, the man pushed the box to the counter, and then sat on a stool not far away. During this period, the man only stood up twice, once when Lin Zhengyi left the lobby, and once when Li Shiwei left the lobby.

Han Bin thinks that the other person standing up is probably just changing the box.

Soon after Li Shiwei left, the man also left with a suitcase. He did not handle any business during this period, nor consulted the bank staff.

Moreover, the man consciously avoided the camera, adding a cap and a mask, almost invisible to his appearance, obviously a little guilty in conscience.

At this time, the case has become clear, the man pushing the box is most likely an accomplice of Li Shiwei.

Han Bin continued to check the whereabouts of the man. From the surveillance at the door of the bank, he could see 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 noted Volvo's license plate number: Lu B343HD.

Then he took out his cell phone and made a call.

"Hey, Team Han." Li Qin's voice sounded in the phone.

"How's your investigation going?"

"I asked the technical department to check the mobile phone numbers under the names of Li Shiwei and Wang Zhixiang, but did not find that they were in direct contact, nor did they have a common contact." Li Qin paused and suggested, "Would you like to expand it? Check the scope to see if the mobile phone numbers of their family members are connected."

"Sister Li, let's put aside the investigation of mobile communication for now. You can check a license plate number Lu B343HD."

Li Qin took down the license plate and asked, "Team Korea, is there any problem with this license plate?"

"We checked the bank surveillance and found that Li Shiwei might have replaced the cash box in the bank. One of the men suspected of his accomplice was driving this black Volvo car."

"I know, I'll check it now."

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