Monitoring and monitoring is Jiang Hao's specialty and he will not accept any refutation.
Jiang Hao pulled out the surveillance video copied from the Wave Bar and used his office computer to pull the video.
When the original video was copied back, the size was nearly 500G. Four or five technical detective colleagues watched it for two days and almost vomited, but no valuable clues were found.
Not all of these 500G videos are about Deng Yi. There are also many useless videos that need to be deleted. At this time, what Jiang Hao got was a streamlined version of the useless videos that his colleagues in the technical investigation had deleted, which could save a lot of time.
.
As per the old rules, the four screens are separated and played at 16x speed. Deng Yi’s every move in the bar quickly appears on the screen.
"Hey! Where are you playing? It's so fast, can you see clearly the jumps?"
Originally, the lighting in the bar was more complicated. Sometimes the monitor screen was reflected by the light tube, and nothing could be seen. Then there were colorful lights again, and the embellished video was even clearer. Now Jiang Hao actually fast forwarded.
Watch it sixteen times.
Anyway, after Hou Fan watched for a while, his eyes couldn't stand it anymore and he retreated in defeat.
"It's okay. I can barely see clearly. I'll do it again for the time being. I'll slow down if there's anything suspicious."
Jiang Hao said without looking back, his eyes fixed on the surveillance video. Jiang Hao, who was close to the limit, did not dare to relax his concentration, otherwise he would really miss it. After all, the speed of sixteen times is not a joke.
"Okay, then you take your time and watch, I'll get busy first."
Hou Fan was so dazzled by this speed that he simply ignored him and turned around to do his own thing.
Jiang Hao's efficiency is really fast. Any suspicious place will be slowed down and read again. After careful inspection, if there is no doubt, he will continue to read.
"Here he finished his drink and put a glass down on the bar. The bartender took it back and, oh, washed it off."
These bartenders were very diligent. Deng Yi immediately cleaned his glass after he put it down, so the fingerprints on it were gone.
"Huh?"
Suddenly, Jiang Hao noticed a detail, so he quickly rewound the video and watched it carefully.
"That's right! A lunch box?! Come here."
Jiang Hao called Hou Fan and motioned for him to come over. He had made a new discovery.
"What's wrong, Xiaojiang?"
"Look."
Jiang Hao pointed to the video and said to Hou Fan.
"Huh? I bumped into it, nothing unusual?"
Hou Fan said with some doubts.
"Look at his hands." Jiang Hao reminded again.
"Oh shit, important discovery, I'll report it to Team Miao immediately."
That's right, in the video, Jiang Hao discovered that Deng Yi was hit by someone once and almost fell down. As a reflex, he grabbed the high chair next to him and stabilized his body.
There is likely to be Deng Yi's fingerprints on this chair, which would be an important discovery.
Miao Xiaofeng rushed over after hearing the news, and then took the technical team and Jiang Hao to the scene to extract fingerprints.
The Wave Bar is still under seal, with a seal on the door.
Carefully peel off the seal and put it aside until you're done and put it back on again.
"Xiaojiang, which chair?"
Everyone looked at Jiang Hao because he was the one who discovered it first.
Jiang Hao observed the surrounding environment and found the area illuminated by the camera that was originally taken, and then walked over, with everyone following behind.
"The location of the video should be in this area. I can't tell which one it is specifically for the past few days. There are only a few high chairs in this area. Let's take a look."
As Jiang Hao spoke, he walked to one of the chairs, pointed to the key position, and gestured: "He grabbed it like this at the time, so the approximate range of the fingerprint is also in this position. Please help me look for it."
, can you extract the fingerprints?"
Professional matters were left to professionals. Jiang Hao didn't know how to extract fingerprints, so he naturally gave up his position to colleagues from the technical team.
Sure enough, after a while, three fingerprints were actually extracted from one of the chairs.
Everyone at the scene was very happy. After so many days, no useful clues were found about this mysterious Deng Yi. Now his fingerprints were finally extracted. Just compare them in the public security fingerprint database to know his identity.
Who is his true identity?
"I really want the technical detectives to study hard. They are also watching videos. How could such important clues be missed?"
"Lunch box, be careful what you say and don't affect internal unity. My colleagues in the technical investigation department are also working very hard. Just watching so many videos is enough for you."
After hearing what Hou Fan said, Miao Xiaofeng reminded him that Hou Fan was not a bad person, but sometimes he spoke bluntly and blurted out without thinking carefully. He could easily offend people if he was not careful.
"Yes, Captain Miao, that's not what I meant." Hou Fan wanted to explain that he really didn't have that consciousness. He just wanted to express that such an important clue could be missed. The words did not convey the meaning and he misunderstood.
"We ourselves know that you don't mean this, but what about the people who don't know you? Okay, pack up and go back and take a look."
After returning, everyone worked non-stop to take the three newly collected fingerprints, enroll them in the system, and start comparing them.
As long as they have a criminal record or are entered on their own initiative, there will be data in the fingerprint database of the public security system across the country. As long as they are compared, the same two fingerprints can be found.
As time goes by, different fingerprint models are constantly being refreshed on the computer screen, but none of them can match.
"It's not in the system, right?"
Hou Fan on the side was very anxious. If the fingerprints he finally found could not be matched, wouldn't his hard work be in vain?
"I can't say for sure. Maybe he is the first offender and there is no information about him in the system, but such a sophisticated method is really not like what the first offender has done."
Miao Xiaofeng also lowered his head and pondered. It was not easy to collect Deng Yi's fingerprint. If it is not in the system, it means there is no clue.
Sure enough, the system matching results came out and the same fingerprint data was not found.
However, Miao Xiaofeng was the team leader and could not dissuade the team members. He took the initiative and said, "It's okay. It's not without gain. At least we collected his fingerprints and we will definitely be able to find him next time."
Although Miao Xiaofeng encouraged everyone, Jiang Hao still felt a little frustrated.
All along, since I got this system, I changed my job to a policeman. Whether it is the skills of a policeman or my martial arts, it has brought great changes to me.
And every time he encounters a case, he always solves it quickly, and every case will be solved within three days.
Therefore, I am still very proud inside, as if there is no case in this world that I cannot solve.
However, reality gave him a blow. The enemy's cunning was not at the same level as before. Faced with high intelligence and detailed crimes, Jiang Hao felt quite helpless.
