274. Gradient and human witness

It was 9 p.m. when I got back to the team, and most of them had already left work.

Ordered a few takeaways to fill their stomachs, Xiao Ran and Zhang Lei went to the technical department, and Li Fangfang transferred to the lounge, he had a duty task tonight.

Naturally, there will be no one in the technical department who works overtime all year round, and the visual detectives in the audio-visual examination room are still checking the surveillance of Chen Ang's residence and Ruan He's community, supplementing the evidence as much as possible.

As for the surveillance footage around Chen Ang's store, it is relatively chicken, and no one cares about it for the time being after it is transferred.

However, from the perspective of Xiao Ran and Zhang Lei, the significance of these monitoring is much more important, after all, their current target is Ruan He, not Chen Ang.

Zhang Lei is going to come to the relevant monitoring, and after the split, Xiao Ran said: "I go from the front to the back, you go from the back to the front, first focus on the 29th of last month, after all, the memory card was taken away that day." ”

Zhang Lei made an 'OK' gesture, Xiao Ran also sat down, and began to look at the surveillance in Chen Ang's store on December 1, which was transferred at the earliest.

For example, a bubble tea shop around a cosmetics store, although there is an external camera, but due to the small storage and high monitoring pixels, you can only see the monitoring content within half a month.

Chen Ang uses a large-capacity hard disk in the store, and the content that can be recorded is naturally relatively extended, just enough to see the situation in the store a month ago.

However, Chen Ang's store uses an ordinary camera, which can only see the situation in the store, and the situation on the side of the road in front of the store can not be seen in the monitoring blind spot.

According to Chen Ang, the first time Ruan He went to his store to buy cosmetics was at the beginning of last month, and I can't remember the specific time, but it was probably the 1st and 2nd.

As for the transcript of the interrogation of Ruan He as an eyewitness, when the investigator mentioned this issue, Ruan He was also vague and did not give an accurate time.

The picture on the display screen is changing rapidly, and the time in reality is passing little by little, and before you know it, it is close to zero, and only Xiao Ran and Zhang Lei are left in the huge audio-visual inspection room, with sour eyes, always paying attention to the doubts that may jump out of the picture.

Xiao Ran had already watched the store and road surveillance for the first three days of last month, but there was no shadow of Ruan He in it, and it was obvious that what Chen Ang said was not accurate.

It wasn't until 5:20 p.m. on the 4th that Ruan He's figure appeared on Wufang Road for the first time.

In the picture, Ruan He got out of the car wearing a white coat, holding a handbag, and although his facial expression was not checkable, he walked into Chen Ang's shop naturally.

This is the situation on the road, and then Ruan He's back appears in Chen Ang's store, which can be seen from the surveillance, at this time Chen Ang is sitting at the counter looking down at his mobile phone, there are not many customers in the store, and a shopping guide sees Ruan He coming in and greets him.

The shopping guide smiled and said a few words to Ruan He, then turned around and knocked on the glass counter in front of Chen Ang.

Chen Ang then raised his head, and when he saw Ruan He, he was obviously stunned for a few seconds, then he stood up with a smile, exchanged a few words with Ruan He, and then took Ruan He to the storage room behind the counter.

Xiao Ran didn't know what happened in the storage room, but from Chen Ang's expression at the first time, combined with the subsequent situation explained by Chen Ang, it can be inferred that this should be Chen Ang's first contact with Ruan He.

After about seven or eight minutes, Ruan He followed Chen Ang out of the storage room with a box of 'C' masks, and Ruan He in the picture looked beautiful, but Xiao Ran's eyes tightened and he paused the video.

Xiao Ran enlarged Ruan He's face partially, and after a closer look, Ruan He's makeup at this time was still different from her subsequent makeup, although it had the shadow of a good face, but it was not as similar as after.

Could it be that Ruan He's makeup is gradually moving closer to Zhang Hao? If so, then what is the purpose of her doing this?

Before Zhang Hao's arrival, he took the lead in bringing out the suppressed sinful thoughts in Chen Ang's heart, so that when Zhang Hao arrived, Chen Ang completely strengthened his determination to commit crimes? Or did he gradually change his makeup and not show it so abruptly, so as not to attract the attention of the people around him, thus leaving flaws?

It seems that it is possible, and with its careful scheming, it is reasonable to do a good job of foreshadowing in advance.

After Xiao Ran made a mark here, he didn't delve into it further, and was about to continue to look down after restoring the picture, but he heard Zhang Lei next to him shouting in surprise: "Look, Xiao Ran, look at it!"

Xiao Ran moved his chair and looked at the screen in front of Zhang Lei, which showed the road surveillance at 8 o'clock in the evening on the 29th of last month, the day after Wang Xiaomei was killed.

I saw that in the picture frozen by Zhang Lei, a man wearing a military coat and holding something was squatting by the garbage can on the side of the road in front of Chen Ang's store, stretching out his right hand to grope for something under the garbage can.

"It's ......"

Xiao Ran's eyes widened, although the location of the man in the picture was relatively dark, but through the bright lights in the cosmetics store, Xiao Ran recognized this person at a glance: it was the uncle they sent back not long ago, known as Lao Ran!

"This ...... That uncle and Ruan He are in the same group? He is pretending to be crazy?"

Zhang Lei also recognized it, but because he was too excited, his thoughts diverged too quickly for a while: "But if he pretended, why did he keep sitting at the door of Chen Ang's store? Is he guarding against us, but looking at the place where he lives, he doesn't look like a normal person......"

"No, maybe someone asked him to help take the memory card when he wasn't confused. Xiao Ran shook his head slightly and said solemnly.

Zhang Lei took a deep breath, but he still couldn't suppress the excitement in his heart: "The 'someone' you are talking about, could it be Ruan He?"

If it's Ruan He, then he's a witness who has seen Ruan He! As long as he can prove that it's the memory card that Ruan He took from him, we will have a reason to act against Ruan He!"

"Look down. ”

Xiao Ran asked Zhang Lei to continue to play the surveillance footage, although the uncle named Lao Liang is suspected of being an intermittent mental patient, but he can still be used as a witness in his waking stage, but who can prove that he has the ability to think when he saw the person who asked him to take the memory card?

The screen continues to play, and the old latch in the surveillance feels the memory card at the bottom of the trash can, first looks at it in front of his eyes for a while, and then stands up and walks straight towards the path where he lives.

Judging from the surveillance, the old man should have the ability to think at this time, but the focus is on the uncertainty of the old man, the video is only his personal behavior, and some mental patients look no different from ordinary people when they are sick.

Monitoring alone is not enough, if you want to establish the identity of the witness of the old bar, you also need to look for someone who can prove that the old man was awake at the time.

Alternatively, there is other direct evidence.

Xiao Ran rubbed his fingertips, looked at Zhang Lei and said leisurely: "This uncle's cat is dead, right?"
