Yu Zerun continued: Also, the administrator is also there, so this thief, he almost can't avoid being seen during the day. ”

Fan Keqin nodded and said, "Have you collected your fingerprints?" ”

Yu Zerun shook his head and said, "I didn't leave any fingerprints, but ...... On the south window sill on the first floor, we found two footprints, but nothing else. ”

Fan Keqin said: "When were the footprints discovered? ”

Yu Zerun said: "At 2:15 during the review, it was found that the safe had been moved, and after the director came at 2:20, he immediately ordered that the people in this building were not allowed to move. The number of guards doubled, and there were guards on all sides of the perimeter, and then we conducted an internal search. Nothing suspicious was found, only two footprints on the south window sill on the first floor, but the footprints were not clear. ”

Fan Keqin asked: "Then, did you take pictures for evidence and protect the scene?" ”

"Yes." Yu Zerun said: "The No. 1 safe, as well as the footprints, has been guarded and sealed since the accident. ”

Fan Keqin said: "If I can, I want to go to the No. 1 safe and go to the window sill on the south side of the first floor." Also, bring me the photos you took at that time. ”

"No problem." It is not the same as Zerun to speak, Xiang Renjian said directly: "Zerun, your task now is to accompany Director Fan and fully cooperate with him." I'm talking about full cooperation, understand? ”

"Understood." Yu Zerun replied: "Don't worry, Director Fan is here to help us catch ghosts, and he will cooperate unconditionally." ”

"Hey." Xiang Renjian nodded, got up and reached out again to shake Fan Keqin's hands, and said, "It was supposed to be me accompanying Brother Keqin, but now that this has happened, I don't know when Shangfeng will call me to find me, I can only stay here, I'm really embarrassed." But Brother Keqin can rest assured that Chief Inspector Yu has been involved in everything from beginning to end, and what you need, just look for Zerun. He's definitely going to do whatever he wants. ”

"Thank you, Director." Fan Keqin smiled slightly and said, "Without further ado, Inspector Yu and I will go over now." ”

"Good. I'll send you. Xiang Renjian spoke, took a step and sent Fan Keqin and the others to the door, and said a few polite words again, and then turned around.

Fan Keqin took Zhuang Xiaoman, Lao Qi and another security bureau agent, led by Yu Zerun, to the first floor again.

The building of the confidential office is very interesting, it is flat and boxy, and the interior is a circular corridor. It's like a hollow zigzag. The offices of various departments and personnel are located on both sides of the corridor.

The location where the confidential documents are stored, that is, Safe No. 1, is in the confidential documents management room, which is located in the lower right corner of the opening in the middle of the hollow shape.

When the group arrived at the place, Yu Zerun led the team, so they ignored the two guards guarding the door with guns on their backs, opened the door and walked in.

When Fan Keqin entered the door, he also asked, whether the fingerprint extraction technology was used in the doorknob and other places, Yu Zerun nodded directly, and replied: "I have used it all, it should be that this ghost is very careful, maybe he is wearing gloves, and there are no effective fingerprints left." In addition, it was afternoon, and although there were a few fingerprints, they were all left by the administrator of the office. ”

After everyone entered, Fan Keqin said: "Be careful, don't destroy the scene." ”

The others confessed and began to divide the search. In fact, Fan Keqin also knew that if what the other party said to him before, if it was true, then the scene had actually been destroyed. What do you mean? That is, they only discovered the ghost at 2:15 p.m. that day. But the time of this ghost's crime cannot be determined, but it may be nighttime, and the details are not clear. However, there is still an administrator working in the office during the day, so the scene must be different from the scene after this ghost completed the crime.

However, Fan Keqin still mentioned it for the sake of rigor. After finishing speaking, regardless of others, he came to the No. 1 safe that Yu Zerun pointed out to him. I didn't move immediately, but I took a closer look.

This safe is about one meter by eighty medium to large safes. On the right is the password knob, and on the left is the keyhole, which is embedded in the wall. The whole is made of all-steel, which looks very strong. Fan Keqin carefully inspected the surface and said, "Brother Zerun, when you opened the door, was the password correct?" Or is it deranged? ”

Yu Zerun said on the side: "Confused, I am now right with the password, and then I opened the door with the key." ”

"Hmm." Fan Keqin looked at the safe and said, "Is there a magnifying glass and a flashlight?" ”

"Yes." Yu Zerun agreed, turned his head to the door and said loudly: "Guard, go to the internal office and bring a hand-held magnifying glass and flashlight." Run forward! ”

"Yes!" One of the guards replied and quickly ran to the right. After a while, he ran back again, and wanted to enter the house but was stopped by Zhuang Xiaoman, who directly took the things in his hand and handed them to Fan Keqin.

Fan Keqin just took the magnifying glass, and then said: "You shine a flashlight on the keyhole, I want to check the situation inside." Remember, when irradiating, you should draw circles, but you should draw circles very slowly and gently, and you should not irradiate them at fixed points. Do you understand? ”

"Understood." Zhuang Xiaoman leaned down, turned on the flashlight switch, shone the light beam at the position of the keyhole, and then softly, slowly drew a circle clockwise. Fan Keqin was holding a magnifying glass, and with Zhuang Xiaoman's movements, he was also drawing circles slightly. When Zhuang Xiaoman's flashlight was in the direction of twelve o'clock, he was at six o'clock. When Zhuang Xiaoman was in the direction of three o'clock, he was at nine o'clock.

This is so because the keyhole is too small and the inside is not straight yet, and the light enters the interior and only partially can be seen if you don't move. But if you adjust the arc slightly, then the inside will be dark and intersecting, changing back and forth, but the whole picture can be seen clearly.

However, under normal circumstances, ordinary people can't see anything, and even the vast majority of professionals can't understand it. Unless it is violently vandalized and the entire door is opened, the inspection can see the inside of the keyhole.

But Fan Keqin has excellent eyesight, you must know that he was a very good criminal policeman in his previous life, and he has been a veteran criminal policeman for nearly 20 years. Among them, there are many major theft cases, and the experience is extremely rich.

And the safes of later generations are much more advanced than in this year. What electronic sensing, voice recognition, fingerprint recognition, pupil recognition and the like are not unusual. The technology content is really very high.
