After looking at the surveillance video around the commissary, I found a problem that made our detection work very unfavorable. That is, the commissary is actually in the blind spot of monitoring all the monitoring.

Lao Lu was very surprised and said: "This murderer is too cunning, he actually chose this commissary in the blind spot of monitoring in this downtown area, it seems that he was in charge of the work before." ”

I frowned and looked at the screen, pondered for a while and said, "No, I think the murderer just stepped on the point and knew that the commissary did not install a monitoring probe, and he didn't know that this was the blind spot of all monitoring." Because to determine if this is a blind spot, a lot of surveillance must be investigated. I believe that the murderer of this kind of murder cannot have such strength. It's just a coincidence, and we can only blame it on bad luck. ”

Lao Lu pouted and nodded with a dissatisfied expression. Of course, his dissatisfaction is not with my analysis, but with the current situation in this blind spot.

Although the murder scene is a blind spot for surveillance, it does not stop our investigation.

Because since the murderer entered the commissary to commit the crime, then he must have passed through the surrounding monitoring probes, so the surrounding monitoring probes must have captured the murderer's figure.

After three days of investigation, we identified three suspicious people from a large number of surveillance videos. And these three people, without exception, are all young lads.

The first young man was a young man with a middle point and a black jacket.

The reason why we suspect him is because he has a very unusual behavior in the surveillance outside the Internet café. And the time of this act coincides with the time of the crime and its coincidence.

On the day of the crime, at 10:49 a.m., the suspect walked out of the door of the Internet café. When he came out, he stood on the steps in front of the Internet café and looked across the road, and the direction he looked was the commissary across the road.

At this time, he quickly ran out of the surveillance screen. Judging by the direction in which he ran, it was to cross the street. So did he cross the street and get to the commissary? This is not known.

The surveillance time was displayed at 10:57, and the suspect reappeared in the surveillance footage outside the Internet café. But this time he didn't stop, but went straight to the Internet café.

So what exactly did he do in those seven minutes?

I went to the Internet café to find out the situation and found that this suspect has a characteristic, he is a frequent customer of this Internet café, and he is a typical Internet worm. It can be said that he spends 20 hours a day in that Internet café.

I retrieved the surveillance video from the network, and found the suspect in the video for many days. And I learned from the webmaster that this suspect has a characteristic, that is, his spending habits are very strange.

This person sometimes spends a lot of money, smokes Chinese cigarettes, and eats takeaway with big fish and meat. But sometimes I eat a bowl of instant noodles a day, or even don't eat them.

From this circumstance, I deduced that the suspect had no regular source of income. Therefore, his consumption habits can show that when he has a lot of money, he spends lavishly, and when he has no money, he lives very poorly. But no matter how tight he is, he will also free up the money to go online. Then the question is, he spends all day in Internet cafes, where does the money come from? Could it be that he has stolen or robbed the money? This is a big suspicion.

So how did the second suspect come into our sights?

The suspect was a young man with a flat head and wearing a white sports coat.

In the surveillance footage of the time period of the crime, he appeared to behave very strangely.

First, we found the suspect in the bank surveillance next to the commissary. Of course, there was nothing obvious wrong with his actions at first, and like other passers-by, he just leisurely passed through the surveillance footage. The time he passed through the surveillance footage was 10:56.

At 11:02, the suspect reappeared on the surveillance footage. However, his appearance this time was very inappropriate.

He ran in a hurry, and he came from the scene of the murder. He ran under the surveillance probe and suddenly stopped, of course, he was not pretending to be calm because the bank had a surveillance probe. Outside the gate of the bank, there was a black SUV parked, and he was standing at the back of the SUV, looking out. The location he looked at was the scene of the murder. And this kind of look of his is not to look all the time, but to look twice, and then he retracts his head, pokes his head out again, and looks twice.

His action lasted about a minute, and then he ran across the road, and the direction he ran in was the Internet café opposite.

In the surveillance of the Internet café gate, we once again extracted the figure of this suspect.

He stood on the steps of the Internet café, looked back at the scene of the murder, and then paced back and forth on the steps, looking very nervous, and looked in the direction of the commissary from time to time.

After pacing back and forth like this for about 3 minutes, he walked into the Internet café. However, after about 2 minutes, he came out of the Internet café again, and quickly disappeared from the surveillance.

In the surveillance video inside the café, I understood why the suspect left the café after 2 minutes. Because after he walked into the Internet café, he was still staring intently at the other side of the road through the glass door of the Internet café.

He had a small gesture that caught my attention. After entering the Internet café, he took out his mobile phone and put it to his ear.

But this action of him was not to answer the phone and make a call, because when he took out his mobile phone from his pocket, he did not dial the phone, did not answer the phone, and did not even glance at the screen of the phone. Then I deduce that this action of his is just an illusion. He just used the posture of talking on the phone to hide people's eyes and ears to hide his inner fear and nervousness.

The last suspect appeared at the intersection not far from the commissary, a young man with a stylish hairstyle and a floral plaid jacket.

The surveillance of the intersection belongs to the high-definition probe, so the person's facial features and behavior are clearly photographed.

He appeared in the surveillance screen very quickly in the form of running, his left hand covering his stomach, and quickly disappeared into the picture. The time he appeared was 10:51, which coincided with the time of the deceased's death.

Later, in the surveillance on the other side of the intersection, we saw the figure of this person again. However, this surveillance probe is not high-definition, and the shooting distance is long. I could faintly see the man hurrying into a supermarket, and when he came out of the supermarket, his left hand had a noticeable white reflection. And the direction after he walked out of the supermarket was to walk out of the public toilet not far from the street.

Could it be that he ran and covered his stomach because of a stomachache? The white reflection on his hand after entering the supermarket is the toilet paper he bought?
