It's a big case, in addition to all the members of the criminal investigation team, as the deputy director in charge of criminal investigation, Yang Junwei also arrived at the scene for the first time.

Several senior police officers will not let go of any possible clues at the scene.

In particular, the lessons learned from the "bus disappearance serial case" some time ago, the main person in charge of the investigation did not let go of even a speck of dust.

However, as a result, at the scene of the crime, the perpetrator left no trace, as if he had disappeared out of thin air. This overwhelmed the entire police force.

If it is said that the last case was indeed not meticulous enough, resulting in a mistake in the early detection work, then what about this time?

The head of the criminal investigation team reported the investigation of the scene to Yang Junwei in a comprehensive and detailed manner.

Yang Junwei's eyes stared at the empty glass cabinet that originally contained important cultural relics, and his heart was not even more uncomfortable.

After listening to the report, Yang Junwei said: "Let's find out if the cultural relics in this glass cabinet were opened by the staff and forgot to close them before they were stolen." ”

The captain of the criminal investigation team agreed, turned around and ran out, and after a while, he ran over with a middle-aged man over half a hundred years old.

"Yang Bureau, I am Zhou Ling, the leader of the working group responsible for the custody of cultural relics, and I dare to tell you responsibly that this cabinet has never been opened. Zhou Ling was slightly excited to explain his work to Yang Junwei.

The responsibility of the cultural relics preservation work is like the bank's vault management work, not only the security arrangement around the cultural relics exhibition hall is very tight, there is only one entrance and exit, and once the entrance and exit is closed, three staff members need to be present at the same time to open.

Entering the interior of the exhibition hall, the monitoring is no dead end, and the glass cabinet where the cultural relics are placed is made of bulletproof and explosion-proof technology, and the glass cabinet needs to be opened, and the three keys of the three staff members are also in place at the same time to open.

At this moment, a man ran in breathlessly at the entrance of the pavilion.

This person Yang Junwei knows, it is the director of the museum and his cousin: Yang Qi.

Yang Qi was in a meeting in the field in the past few days, and when he heard the news of the theft of the cultural relics in the exhibition hall, he immediately rushed back.

"Junwei, have you found any clues?" he asked eagerly as soon as they met.

Originally, on such a formal occasion, no matter what the relationship was, it was usually called according to the position, but he obviously ignored it.

Yang Junwei understands his mood at this time, his cousin, an old party member, is also diligent in his work, and the key point is that he can't hold his breath, so he has been staying in this museum all these years.

"Director Yang, there are no clues yet, but there is a job that requires your cooperation, all the personnel related to this museum, please arrange it, and they must go to the criminal investigation team for investigation. Yang Junwei patted his cousin on the shoulder, explained some things to the captain of the criminal investigation team, and then returned home.

"Dad, do you have to be so busy on weekends?" As soon as she entered the door, her daughter Yang Ling asked.

As soon as the open class ended, Yang Linger took Zhang Yang home. As soon as I got home, I realized that my father was busy with some cases.

"Your uncle's museum has been stolen and an important artifact has been lost. And this is not an ordinary cultural relic, but it is something that the emperor of the Tang Dynasty, Li Shimin, once used, is priceless. Yang Junwei replied, and at the same time asked, "Zhang Yang, is your open class over?"

"Yes, uncle. Zhang Yang said with a smile. Then he asked, "When did you just say that the museum artifacts were stolen?" he asked casually.

"According to our analysis, it should be this Wednesday. Yang Junwei smiled and said, "Zhang Yang, do you have any suggestions?" Because of the last case, he looked at his future son-in-law differently.

"As soon as I got home, I talked about the case, and asked Zhang Yang, you should be Zhang Yang is your policeman!" Xu Dujuan immediately interrupted Yang Junwei's speech.

"Mom, Zhang Yang can do it, in the last case, he made some suggestions, and Dad successfully solved the case. At this time, Yang Ling'er said a word.

Yang Junwei laughed and said, "It's still my baby daughter who understands me!"

Xu Dujuan glared at him, turned around and greeted Zhang Yang, "Zhang Yang, it's time to eat." ”

Zhang Yang answered, but he was thinking in his heart, isn't Wednesday the seventh day of our open class, that is, the day he found out that Ying Bu was missing?

So, during the meal, he asked Yang Junwei: "Uncle, have you checked some surveillance videos before the disappearance of cultural relics, such as public exhibitions?"

"I checked the video of the last time, which is this Monday, but it is normal, all the tourists who come, until the museum closes, the cultural relics have been there. ”

"Oh, then in the next few days, I don't know if the surveillance has been videotaping. Or is there a pause in between?" Zhang Yang continued.

Yang Junwei nodded, he had already explained this matter to the captain of the criminal investigation team before leaving just now. said: "There should be news tomorrow morning." ”

There was nothing to say all night, and early the next morning, Yang Junwei received a call from the captain of the criminal investigation team, saying that the surveillance video of a few days was normal, that is, before the cultural relics were found and disappeared, the video seemed to be a little stuck, but no abnormality was found.

At breakfast, he exchanged the report of the criminal investigation captain with Zhang Yang.

Zhang Yang thought about it and felt that he didn't see the video, so he didn't have the right to speak at all, so he asked, "Uncle, can I watch the video in the past few days?"

"Yes, of course!" Yang Junwei said. He had made a phone call to the head of the criminal investigation team and asked him to send a copy of the video to his home.

Later, when I thought that this would be more time-consuming, I asked Zhang Yang to follow him to the police station, because with Zhang Yang, the bicycle was too slow, so I asked my eldest son to drive it.

Yang Ling'er didn't expect to go, but when she heard that her eldest brother drove over, she was the first to get in the car.

After a while, the car stopped in the internal parking lot of the police station, and Yang Junwei and the four pushed open the office of the criminal investigation team on the second floor.

The surveillance video on the opening day of the exhibition hall did not find any abnormality, but Zhang Yang found an acquaintance among the visitors: Ying Bu.

Immediately, he thought, wasn't Ying Bu listening to a public class, why did he have this leisure to come and see cultural relics?

Immediately afterward, he discovered the anomaly of the video stuttering.

If you change to any person, you may not be able to find anything, but after Zhang Yang appeared in the blurry video of his No. 001 reconnaissance plane during the summer vacation, he repeatedly studied the reasons for this and found a solution to this phenomenon, and at the same time, he also understood that the reason for this phenomenon was the interference of external forces.

The phenomenon of video jamming is actually the simplest way in science and technology, which is to access a stem called GFW on the monitor

AO device will do.

Judging from the external performance, the surveillance seems to be still in the normal video, but in fact it is stuck in the GFW dry

Information before the AO is accessed.

He told Yang Junwei all of his discoveries.

The captain of the criminal investigation team, who had been standing on the side without a sound, opened his mouth wide, who is this, there are more cows than "Mr. Di"!

The next work is much simpler, the first thing to start with: to check all the internal personnel on duty that day, and the second to do things, to investigate all the movements of Ying Bu in the past few days.

On the third day, not only did the case come to light, but even Ying Bu, who Zhang Yang had been trying to find, was also arrested, and his co-defendants in the same case were Ying Bu's two apprentices and a staff member on duty that day who was sold by Ying Bu in the museum.

Even Ying Bu himself didn't expect that his two crimes fell into the hands of the same college student. Not long after, because of Yang Junwei's meritorious work in solving the case, and the transfer of the former director to the city bureau, he was directly promoted to the director of the Dongzhen County Police Department.
