While everyone was still recalling Teng Jie's judgment, Bai Mo came to the whiteboard and picked up a pen.
Lu Wan had previously drawn a timeline when describing the case. The starting point was two days before Bai Mo attended the art exhibition. The murderer contacted Qin Peng and asked him to find Liu Mingxing to deliver the painting to the art exhibition.
These two key time points are the Sunday when Bai Mo discovered the painting. There is no key mark on the Saturday between Friday and Sunday. In Lu Wan's opinion, only one thing happened on that day - Liu Mingxing hung the painting.
But Bai Mo suddenly felt that something was wrong. He just thought of the simplest way. In order to make sure that no one noticed his paintings, the murderer would definitely go to the art exhibition for two consecutive days.
You know, there are not many paintings in the art exhibition. Even one day is enough to appreciate them carefully. There are very few people who go to the art museum for two consecutive days. So Bai Mo only needs to find people who go to the art museum for two consecutive days. That’s it?
The problem is naturally not that simple. It is impossible for the murderer not to consider this, so the murderer probably only chooses one day to go.
So is it Saturday or Sunday? After all, people who love painting generally choose to go there on Saturdays. They all can’t wait to participate in the art exhibition.
The same is true for Bai Mo. If it weren't for attending Teng Jie's autograph session, he would definitely go there on Saturday.
Bai Mo was shocked when he thought of his own reasons. The murderer was a fanatical fan of Teng Jie. How could he not attend Teng Jie's autograph signing?
If he went, he would definitely keep an eye on Teng Jie. Then would the murderer know that Teng Jie pretended to leave and came back on purpose, and would he see Bai Mo and Teng Jie drinking coffee?
Bai Mo drew a big asterisk on the timeline while describing his analysis.
"I didn't express much shock when I saw the painting that day. I went to the curator privately to investigate the painting. When I went to pick up the painting, it was after get off work on Friday. How could the murderer do it every day? Are you waiting at the entrance of the art museum?" Bai Mo's tone became excited.
yes! If the murderer goes to the art gallery every day to confirm his paintings, then he only needs to investigate the comings and goings of the art gallery.
"So!" Bai Mo took a deep breath, "He started paying attention to me when he saw me on Sunday, because he also saw me in the bookstore on Saturday!"
Sometimes solving a case is like this, looking for the most reasonable one among countless hypotheses. The convinced eyes of everyone prove that they all think Bai Mo's hypothesis is the most reasonable.
Lu Wan's expression became a little stiff, "There should be surveillance at the entrances of the bookstore and art museum, right?"
······
No one fell asleep that night. Lu Wan came to monitor the bookstore overnight, and Zeng Hao came to monitor the entrance of the art museum. There was a reference.
The art museum needs to watch videos throughout the day. Lu Wan divided the bookstore's surveillance into many groups according to time periods, and everyone grouped them for comparison.
Bai Mo's comparison speed is the fastest, and his comparison method is different from everyone else's.
He first looked at the museum's surveillance alone. The flow of people in the museum was relatively small, and there were rarely swarms of people at the entrance, which made it easier for him to remember faces.
After that, Bai Mo read the bookstore's surveillance at double speed. Due to Teng Jie's huge readership, the bookstore entrance has a large flow of people, but for Bai Mo, double speed is just right. If the flow of people is not large, he can use triple speed or four times. Play at double speed.
At four o'clock in the morning, when everyone was still counting faces in the art museum, Bai Mo had already finished watching a group. The main difficulty was monitoring the entrance of the art museum, because it needed to be viewed throughout the day, so everyone's time was wasted here.
Chen Xiaoxiao was in a group with Bai Mo. She was exhausted. Part of the reason was Bai Mo. Playing at twice the speed made her dizzy.
What's even more outrageous is that Bai Mo seems to have endless energy. After watching the time period between the two of them, he asked for Lu Wan's.
Snapped!
The sound of Bai Mo typing on the keyboard rang out throughout the office, followed by his excited voice, "Found it!"
This was the first time anyone had spoken so loudly in the office since one o'clock in the morning.
Zeng Hao, who had been napping on the table, straightened up suddenly, and even Teng Jie, who was resting in Lu Wan's small office, was woken up.
Everyone gathered around, but on Bai Mo's computer screen there was only the surveillance picture of the bookstore, a frozen surveillance picture.
Bai Mo pointed at one of the men in a suit and said, "That's him. He went to the art museum at almost ten o'clock the next morning."
The man in the picture looks to be in his thirties, has a Chinese character face, and looks rather fierce. He is crowded in the crowd, and only his chest can be seen.
Chen Xiaoxiao on the side quickly called up the entrance surveillance of the art museum and found this man in the surveillance screen at 9:50. The man was wearing a brown jacket and glasses, and he had exactly the same temperament as when he was wearing a suit. different.
"This person..." Teng Jie was still sleepy and his expression was a little dull.
It's no wonder that Teng Jie is not a professional criminal policeman. Staying up late is a big challenge for him.
Teng Jie yawned and shook his head, "This person probably didn't ask me for an autograph."
"Are you sure?" Lu Wan asked first, and then asked Chen Xiaoxiao to call up surveillance from other angles in the lobby on the first floor of the bookstore.
"Definitely not." Teng Jie had already sobered up a lot, and he thought: "He is older and has a distinctive appearance. If such a person asks me for an autograph, I will definitely be impressed."
Chen Xiaoxiao called up surveillance from other angles. As Teng Jie said, this person entered the elevator directly after entering the lobby.
"Is it a coincidence?" Chen Xiaoxiao murmured. Everyone had already determined that the murderer was a fanatical fan of Teng Jie. How could they not take this opportunity to have a close contact with Teng Jie? "
"Rewind the scene, I want to see his back." Teng Jie said in a deep voice, his tone had changed, it seemed that he had made a major discovery.
Chen Xiaoxiao quickly followed the instructions and found a picture of a man's back before entering the elevator.
"Suck-" Tengjie took a breath of cold air.
Lu Wan grabbed Teng Jie's arm with concern, and everyone else looked at Teng Jie.
Teng Jie looked at Bai Mo with a difficult expression, and Bai Mo was also looking at him.
"Remember the coffee shop on the eighth floor we went to?" Teng Jie said.
Bai Mo nodded slowly. He had vaguely guessed what Teng Jie had discovered.
"This man should be sitting next door to us. His back was to us. I only saw the back of his head." Teng Jie said, "The time should be around twelve o'clock. I pretended to leave and came back to find Bai Mo." , and then we went to the coffee shop on the eighth floor.”
Chen Xiaoxiao called up the surveillance camera at the time Teng Jie said. At the entrance, Teng Jie came and went, and then the man followed him in.
