After collecting a circle of teacher's fingerprints, a few people left the school, Wei Zengmai was still chatting with Chen Shi all the way, "Uncle, Yueyue has such good grades, do you usually open small stoves?"
"It's mainly about eating well, I usually cook, and I don't make a heavy meal."
"Wow, do you cook by yourself? That's amazing!"
"Show off in disguise!" Lin Dongxue smiled, "Old Chen, I have something to tell you."
Chen Shi said to Tao Yueyue: "You and Mary go buy an ice cream."
Tao Yueyue understood and took Wei Zengmali away. Lin Dongxue said, "Among those teachers, do you have any doubts?"
"nothing now."
"Actually you still have them, just for fear of misleading me."
"Haha, Dongxue who knows me too."
"But the date of Teacher Lin’s disappearance, now everyone agrees that it is October 1. When she received her parents just now, his father mentioned that he asked Lin Xiaoxiao to go home for dinner that day. Lin Xiaoxiao entered the community and gave him a box. , Saying that he couldn't eat because of something, so he left."
"What box?"
"It's just a footwashing machine for my parents."
"What about the time?"
"At around four o'clock in the afternoon, that is to say, her father was the last to see her."
"As a result, on October 1st, three eyewitnesses proved that she was alive."
"Yes!"
Chen Shi always feels a bit weird. It's all eyewitness testimony. Wouldn't it be the best for Teacher Lin to set off on September 30
She went to school on October 1st and did nothing. It seems to be just to be "seen". What's more abnormal is that she dropped her mobile phone to leave information, which can be replaced by a piece of paper. .
Abnormal!
The three eyewitnesses on October 1 are all questionable.
Chen Shi said: "I want to look at the surveillance at the school and her neighborhood to verify these eyewitness testimonies."
"Didn't you promise to stay with Yueyue tonight?"
Chen Shi looked helpless. At this time Tao Yueyue and Wei Zengmai came back with three chocolate ice creams. Tao Yueyue handed one of them to Lin Dongxue. Lin Dongxue said gratefully, "Thank you!"
"Yueyue, I have to work overtime tonight." Chen Shi said.
Tao Yueyue was very calm, "Oh, then I'll go to Mary's home to do my homework!"
Wei Zengmali said happily: "Just eat at my house. By the way, you can help me with my homework."
"Mary, I'll trouble you... Yueyue, do you still have pocket money? I'll transfer it to you!"
"Uncle Chen!" Tao Yueyue said in a reminding tone.
"Yes, forget it!" Chen Shi smiled, remembering his previous promise, hugged Tao Yueyue, patted her on the head, "I will pick you up at night."
"Don't come back too late."
Then Lin Dongxue and Tao Yueyue hugged, and the two children walked side by side. Only then did Chen Shi drove away with Lin Dongxue.
After getting the monitoring of the community where Teacher Lin’s father lived, the two returned to the bureau. Many people in the second team were working overtime today to watch the monitoring. Xu Xiaodong was eating a cup of noodles at the computer, and Chen Shi patted him on the shoulder from behind. "What did you find?"
"Although there was no monitoring on October 1, but on the evening of the 30th, Teacher Lin did leave the school normally."
"Let me see."
Xu Xiaodong went back to that section, and indeed there was a scene of Teacher Lin walking out side by side with another female colleague. It was six o'clock in the evening.
Everything is so natural.
Chen Shi found a computer, played the surveillance of the community, and watched. Suddenly an object flew in the screen, the screen vibrated, and then the whole screen turned to the other side, and the entrance of the community was not photographed at all. All of the pictures are bushes.
"What's going on?" Lin Dongxue said.
"I'll go back."
Rewind to that paragraph, pause, and then play frame by frame, and pause again at a certain frame. The suspicious object in the picture is already very close, and there are some regular geometric patterns on it. Lin Dongxue said: "This shouldn't be a Football?"
"It seems to be so. This is a coincidence. I don't know which teenager Zidane kicked the camera head with a kick. The key pictures were not taken."
"It is estimated that the monitor is still crooked, and the security hasn't noticed it."
Chen Shi was silent, and said for a long time: "Let's take another look at the school's surveillance on September 30."
When Chen Shi played the segment, Lin Dongxue stared at the screen and said, "What are you doubting? Why did you watch this segment of surveillance? On October 1st, many surveillances near the school were also recovered."
"I'll talk about it later!"
Chen Shi had a vague guess. Someone played a trick at the time. He reached out and pressed the space, and the scene stopped at the scene where Teacher Lin and his colleagues walked out side by side.
After thinking about it for a while, Chen Shi turned the monitor forward. A large number of students were walking out. The picture was messy and the pixels were a bit blurry.
Lin Dongxue didn't know what he was looking for, and got up to pour him a glass of water, but Chen Shi suddenly grabbed her hand, "Here!"
"What's wrong?"
Chen Shi zoomed in and pointed to a little girl, "This is Tao Yueyue."
Lin Dongxue smiled, "So you were looking at her."
"Tao Yueyue wears jeans, but this pair of jeans was splashed and dirty by a car on the way from school on September 29. I washed it by myself. She was wearing a plaid skirt on September 30."
"Could it be..."
"Someone used the previous day's monitoring to cover the September 30th monitoring."
"But this time shows that it is September 30th."
Chen Shi pointed to the upper right corner, "This '1' is a bit vague and has been tampered with. Just make a layer on the video editing software and cover it, export it, and change the name. It becomes September 30. Video of the day."
"I'm going to look for surveillance on September 29!"
Lin Dongxue found the monitor and played the two at the same time. She was surprised to find that the monitors for the two days were exactly the same except for the date.
"Everyone, a major discovery!" Lin Dongxue slapped her hands.
Everyone gathered around and expressed surprise at the discovery. One police officer said ashamed: "I'm paralyzed. I read both paragraphs, but I didn't expect them to be the same."
"The monitoring of the school entrance looks the same every day at first glance, don't blame you!" Chen Shi said.
"But why change the monitoring on September 30? Isn't the missing time October 1st?"
"This shows what happened on September 30. Maybe this day is the date when Teacher Lin really disappeared."
"No, there were three people who witnessed Teacher Lin on October 1. Even if the school worker and Teacher Liu lied, it's impossible for her father!" Xu Xiaodong said.
Chen Shi was also silent, how did this happen!
He became more and more convinced that this was by no means an ordinary case. The murderer used some means to postpone the time of disappearance by one day. It can be seen that the starting point of the incident may be an emergency, which cannot be changed by itself, so the murderer must be in time. Do tricks.
After a long silence, Chen Shi asked, "Who is the criminal who stole Chinese cigarettes?"
