Yu Zerun continued: "Also, the administrator is also there, so this little thief can hardly avoid being seen during the day." "
Fan Keqin nodded and said, "Have the fingerprints been collected?"
Yu Zerun shook his head and said: "No fingerprints were left, but... we found two footprints on the south window sill on the first floor, but nothing else."
Fan Keqin asked: "When were the footprints discovered?"
Yu Zerun said: "During the review at 2:15, it was found that the safe had been tampered with. After the director came at 2:20, he immediately ordered that no one in this building was allowed to move. The number of guards was doubled, and the number of guards around the perimeter was There were also guards on guard, and then we conducted an internal search. We didn’t find anything suspicious. There were 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 photos to collect evidence and protect the scene?"
"Yes." Yu Zerun said: "Safe No. 1 and the footprints have been guarded and sealed since the accident."
Fan Keqin said: "If possible, I would like to take a look at safe No. 1, and go to the window sill on the south side of the first floor. In addition, please bring over the photos taken at that time."
"No problem." Instead of Zerun speaking, Xiang Renjian said directly: "Zerun, your task now is to accompany Director Fan and fully cooperate with him. I mean fully cooperate, do you understand?"
"Understood." Yu Zerun replied: "Don't worry, Director Fan is here to help us catch ghosts. I will definitely cooperate unconditionally."
"Hey." Xiang Renjian nodded, stood up and stretched out his hand to shake Fan Keqin's hand again, and said: "Originally, I was supposed to accompany Brother Keqin, but now that this happened, I don't know when we will go up to the peak." Call me, I can only stay here, I'm really sorry. But brother Keqin, don't worry, Chief Inspector Yu has been involved in everything from beginning to end. If you need anything, just ask Zerun. He will definitely respond to your request."
"Thank you, Director Xiang." Fan Keqin smiled slightly and said, "That matter should not be delayed. Inspector Yu and I will go over now."
"Okay. I'll see you off." Xiang Renjian said, took Fan Keqin and others to the door, said a few polite words again, and then turned around.
Fan Keqin brought Zhuang Xiaoman, Lao Qi and another Security Bureau agent, led by Yu Zerun, back to the first floor.
The building of the confidential office is very interesting. It is flat and square, with a circular corridor inside. It's like a back shape. The offices of various departments and personnel are on both sides of the corridor.
The place where the confidential documents are stored, that is, safe No. 1, is in the confidential document management room. This management room is in the lower right corner of the opening in the middle of the back shape.
When the group arrived, they were led by Yu Zerun, 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 fingerprint extraction technology was used on door handles and other places. Yu Zerun nodded directly and replied: "I have used it all. The mole must be very careful, maybe wearing gloves. There were no valid 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 not to damage the scene."
The others made their confessions and began to divide their work and search. In fact, Fan Keqin also knew that if what the other party told him before was true, then the scene had actually been destroyed. What's the meaning? That is to say, they didn’t discover the ghost until 2:15 that afternoon. However, the time when this ghost committed the crime cannot be determined. It may be at night, but the specifics are unclear. However, there were still administrators working inside during the day, so the scene must be different from the scene after the ghost committed the crime.
However, Fan Keqin still mentioned it for the sake of rigor. After saying that, without caring about anyone else, he came to the safe No. 1 pointed out to him by Yu Zerun. He didn't move immediately, but observed it in detail.
This safe is about one meter by eighty meters, a medium to large safe. On the right is the password knob, and on the left is the keyhole, which is built into the wall. The whole thing is made of steel and looks very strong. Fan Keqin checked the surface carefully and said, "Brother Zerun, when you opened the door, was the password correct? Or was it wrong?"
Yu Zerun said from the side: "What's wrong is that I corrected the password and then opened the door with the key."
"Yeah." Fan Keqin looked at the safe and said, "Do you have a magnifying glass and a flashlight?"
"Yes." Yu Zerun agreed, turned to the door and shouted loudly: "Guard, go to the internal office to get 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. He took what was in his hand and handed it to Fan Keqin.
Fan Keqin just took the magnifying glass, and then said: "You shine the keyhole with your flashlight, I want to check the situation inside. Remember, when shining the light, you have to draw a circle, but you have to draw the circle gently and extremely slowly. No fixed-point irradiation. Do you understand?"
"Understood." Zhuang Xiaoman leaned down, turned on the flashlight switch, shined the beam on the keyhole, and then gently and slowly drew circles clockwise. Fan Keqin held a magnifying glass and followed Zhuang Xiaoman's movements, drawing slight circles. 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.
The reason for this is because the keyhole is too small and the inside is not straight, and the light enters the inside and you can only see part of it if you don't move. But if you adjust the arc slightly, the interior will be dark and dark, changing back and forth, but the whole picture can be seen clearly.
But under normal circumstances, ordinary people can't see anything, and even most professionals can't understand it. Only after violent destruction, the whole thing is opened, and the situation inside the keyhole can be clearly seen through inspection.
But Fan Keqin has excellent eyesight. You must know that he was an excellent criminal policeman in his previous life, and he has been an experienced criminal policeman for nearly twenty years. He has encountered many major theft cases and has extremely rich experience.
And the safes of later generations were much more advanced than these days. Electronic sensing, voice recognition, fingerprint recognition, pupil recognition and the like are no longer uncommon. The technological content is really very high.
