    "What can be done?" I asked curiously.

    "I just heard what you said and I think we can make an image overlay."

    "What? Image overlap? What kind of high-end thing is this?"

    Fat Lei lit a cigarette: "This Geng Tianqiu was in prison before. The prison is also a place with the most intensive video surveillance coverage. We can retrieve the video from the prison and intercept a video of Geng Tianqiu walking.  I then use processing software to mark the heads, limbs, torso and other positions of the two monitored figures as feature points to create a 3D simulation image. If the simulated images of the two monitored figures can overlap during walking, this will  It means that the suspect can be confirmed to be him. If it can be confirmed, then our remaining work is to find evidence around this person. The target is so clear, do you think it can still stump us professionals? "

    ¡°Oh my god, Brother Lei, you are so awesome. You know how to do such high-end things?¡± I gave him a thumbs up.

    ¡°That¡¯s right, Brother Lei, I am a genius in graphics, how can this trouble me?¡± The word humility has never been in Fat Lei¡¯s dictionary.

    "But Geng Tianchou has been released from prison for several years. Can the surveillance in the prison be preserved for such a long time?" Ye Qian's words poured out the small fire I had just lit until not even a spark was left.

    "That's right, Brother Lei, can't normal monitoring only be stored for one month? It's been several years, where can I adjust it?" My face was sometimes cloudy and sometimes rainy.

    "The prison's monitoring storage capacity is so large, it is definitely impossible to store it for a long time. Otherwise, how many hard drives would they need to store it? The monitoring is basically deleted on a regular basis!"

    "Brother Lei, are you kidding me?"

    "But!" As soon as I rolled up my sleeves, Fat Lei raised his hand to stop, and these two words came out of his mouth.

    "But what? Just tell me!" I urged from the side.

    "Ordinary surveillance must be deleted, but some special surveillance will be kept for a long time, such as seeing a doctor in prison, violating prison regulations, etc. If you want to find it, you can find it in such a large video network system.  There¡¯s nothing wrong with the picture at all.¡±

    "I'll go, why are you talking like Lao Xian now, and you like to breathe heavily, so what are we waiting for? Let's go quickly!"

    ¡°Okay, let¡¯s report this to Brother Ming, and we¡¯ll leave. Anyway, the prison is staffed 24 hours a day.¡±

    After Brother Ming learned the ins and outs of this incident, he immediately decided to go with us, leaving Lao Xian to look after the family in the department.

    In our province, there are basically two places for sentenced criminals, one is the Baihu Farm Prison in Guohu City, and the other is the Diesel Airport Prison in Liuhe City in the provincial capital.

    Some people may ask, why does this prison have such a strange name?  This is mainly because criminals serving their sentences in prison need to work on a daily basis. The so-called reform through labor, how can they be reformed without labor?

    Taking the Baihu Farm Prison in our province as an example, the labor reform for prisoners during their sentences was farming. Because there has been less and less arable land in recent years, Baihu Farm has been transformed into a handicraft industry.  And this diesel airport prison can be understood very literally.  Our province has a rule that serious criminals (more than ten years, life imprisonment, suspended death) are basically sent to Diesel Airport, while the remaining criminals serve their sentences at Baihu Farm, and the purpose of our trip is Baihu Farm.

    Our car drove directly to the administrative building outside the prison area. After submitting the relevant procedures, the police officer on duty led us into an ultra-high-end video surveillance room.  The wall facing the door of the monitoring room is divided into countless video screens. I'm not exaggerating. I can't count the number anyway.

    There are more than a dozen rows of hundreds of long tables in the room, and two computers are neatly placed on each table. Dozens of staff are wearing headphones to switch back and forth between the screens of the prison area.

    "Pang Lei seemed to be familiar with this kind of scene. He ran up to a police officer carrying a three-star bar on his shoulder very familiarly. After a few words of communication, the man stood up and made way for Pang Lei.

    When we saw this, we all gathered around.

    ??Pang Lei¡¯s two chubby hands skillfully operated the keyboard and mouse. It didn¡¯t take long for him to back up several clear images.

    ¡°Okay, that¡¯s enough!¡± Fat Lei pulled out the USB flash drive from the computer and said confidently.

    After we said goodbye to our colleagues in the prison system, we headed back to the unit without stopping.

    As soon as Fat Lei stepped into the courtyard of the department, he ducked into his office.  This kind of technology lives up to us.I wasn't too busy, so I planned to take this time to rest for a while. Unexpectedly, Brother Ming, who didn't miss any detail, closed another loophole in the clues - the stolen Suzuki motorcycle.

    No matter how good the comparison is with Fat Lei's video, it can only be a side piece of evidence. And that motorcycle has been in contact with the suspect for a long time. If fingerprints or DNA information can be extracted from it, then the case will be closed.  The case can be immediately announced as solved.  Sometimes I think about it, I really lost the watermelon and grabbed the sesame seeds. I couldn't figure out which end was heavier and which was lighter. Fortunately, Brother Ming was there to guide me in the general direction.

    ¡°Half an hour after Fat Lei got into the office, a small truck carrying the motorcycle came to the yard. Lao Xian and I had already prepared our professional tools early and were ready at all times.

    Motorcycles, the most common form of transportation, are not very difficult to handle. The entire extraction and processing work by Lao Xian and I only took more than an hour.

    While we were processing the traces, good news came from Fat Lei. The suspect's 3D simulated walking posture is 90% similar to Geng Tianqiu. From the side, we can basically prove that he is very likely to be  suspects.

    Because Geng Tianchou was once handled by the public security agency, his fingerprints, footprints, and DNA samples are all archived here. The rest of the work couldn't be easier. As long as Lao Xian and I can handle it on the motorcycle, we can do something about it.  If there is physical evidence linked to him, then we can close the net directly.

    But things did not go as smoothly as we imagined. All the fingerprints on the motorcycle were excluded, and the DNA detected by Lao Xian did not match Geng Tianqiu at all.

    With the support of Fat Lei¡¯s video overlay technology, Brother Ming immediately decided to summon Geng Tianchou to the criminal police team and then launch a search of his home.  This is the most immediate method. Just imagine, if we find stolen gold bars and jewelry in his home, or find the pair of shoes he wore in the deceased's home, any of these can directly convict him.

    But this method has a considerable drawback. If the evidence can be found, everyone will be happy; if not, Geng Tianchou will definitely be alert, and it will be more difficult to find enough evidence to solve the case in the future.

    However, as far as this case is concerned, there is no solution.  Because we have judged in advance that the suspects of the gold bars most likely did not sell the stolen goods, Ming's decision was not a reckless one.

    For people released from labor camps like Geng Tianqiu, the police station in their jurisdiction will carry out legal education from time to time, so with just a few phone calls, we found out exactly where Geng Tianqiu lives.

    In order to prevent any omissions in the search, we rushed to Geng Tianqiu¡¯s residence when the light was the strongest the next day.  One minute before we arrived, he had already been taken away by investigators from the criminal police team.  (Remember the website address: www.hlnovel.com
