Kotodo Medical College.

Han Bin and others rushed to the school, and they were still received by Wang Jinliang, deputy director of the school's Academic Affairs Office, and Ma Tao, director of the Analysing Teaching and Research Department.

Guo Tianxu gave them a brief introduction to each other.

Wang Jinliang took the initiative to shake hands with Han Bin, "It turned out to be Captain Han, disrespectful and disrespectful." ”

Director Wang was polite. Han Bin shook the other party's hand and proposed, "We want to go to the scene to have a look." ”

"Yes, here, please. ”

Under the leadership of Wang Jinliang, the group rushed to the storage room of the teaching and research building again.

As soon as I entered the second floor of the basement, the air pressure around me felt low, and the faces of Yanzi, Xiaoyan, and Dahan were a little dignified in the dim light.

Han Bin and the three have not changed much, most of the cases they handle are homicide cases, they have seen all kinds of deaths, and they have far more contact with the dead than the police at the police station.

Along the way, Han Bin was observing the cameras, and he found that there were surveillance cameras at the entrance of the teaching and research building, in the hall, and in the corridor on the second floor of the basement, and these cameras may have captured the suspect.

Everyone walked to the house number 207, and Ma Tao stopped, "This is the storeroom where the general teacher is stored." ”

Han Bin asked rhetorically, "You were the first to find out that the general teacher was stolen?"

"Yes. ”

"Was the door to the storage room closed or open, and did the lock show any signs of being broken?"

Ma Tao thought for a while, "I didn't pay much attention to it at the time, I just opened the door normally and went in, and I didn't find anything abnormal." ”

Han Bin took out a police flashlight and carefully checked the lock, and there was no obvious trace of being picked, which means that the suspect either had a key or a professional lockpicking tool.

"Who has the key to this door?"

Ma Tao replied, "I have a key here, and the rest are in the general affairs office." I don't know how the General Affairs Office keeps it. ”

Han Bin turned his head to look at Wang Jinliang on the side, "Director Wang, are you from the Academic Affairs Office?"

"Yes, I'm the Deputy Director of Academic Affairs. ”

Han Bin asked rhetorically, "I remember that the logistics should be managed by the General Affairs Office, why didn't the people from the General Affairs Office come, but you came?"

Ma Tao took over the conversation, "Logistics is indeed in charge of the General Affairs Office, but I am solely responsible for the teachers regardless of them, after all, most people are afraid of this thing." Director Wang is mainly responsible for the students' course arrangement, and the two of us generally coordinate and arrange the anatomy class. ”

Han Bin nodded, "Then please contact the General Affairs Office, I want to know about the preservation of the key to this storage room." ”

"Yes, I'll get in touch. Wang Jinliang didn't want to stay here either, so he just found a reason to leave first.

Han Bin looked at Ma Tao again, "Director Ma, how do you keep that key?"

"Bang la......" Ma Tao shook the round key ring in his hand, which was full of keys, and each key was pasted with white tape, and the house number was written on the tape.

"My keys are locked in a drawer, and I always carry the keys to that drawer, because there are more keys, and I pay more attention, and I can guarantee that the keys have not been lost or used by others. ”

Han Bin opened the door with gloves on, and a strong smell of potion came to his nose, "Good guy, it's really choking." ”

Ma Tao explained, "Human organs are prone to decay and can only be soaked in potions for embalming. ”

Han Bin turned his head and told everyone, "Don't touch the things in the house, Sister Li called the technical department and asked them to come over to investigate the scene." ”

"Yes. ”

Entering the storage room, Han Bin looked at the environment inside, the room was full of glass jars, and the jars contained all kinds of organs, if a timid person came in, he would have to be scared half to death.

Han Bin's eyes fell on the surveillance camera above the door, frowning slightly, "The general camera is installed on the door, and the thief can be photographed as soon as he enters the door." The camera in this storage room is facing inside, and the thief can completely block the camera after entering the storage room to steal, don't you feel awkward when this camera is installed?"

"We didn't think too much about it, and at that time, in order to save money, we asked the school's maintenance staff to install it, and they thought that it would be more economical to wiring it this way. Afterwards, I also found that it was a little awkward, but the monitoring has been done and used normally, and if you reinstall it, you have to declare, and it is not a department's business...... And so it ended. There was some helplessness in Ma Tao's tone.

Han Bin didn't bother to care if his helplessness was true, or if he was afraid of trouble.

"Has anything else been stolen besides the male teacher?"

"Probably not. ”

Give me an accurate answer. ”

"I found that the teacher was lost, and the whole person panicked, and I didn't bother to check it carefully. With that, Ma Tao began to check in the storage room.

After a while, Ma Tao's tone was firm, "I didn't lose anything else." ”

"Are there any more items?"

"Nope. ”

"Are there any signs that the other items in the storage room have been touched or touched?"

"I don't have the impression of it. ”

"Do you have any suspicions about the theft of the teacher?"

Ma Tao sighed, "I can't think of it." ”

"Who will benefit from this?"

"How do I say that, if I am removed, the person who replaces me will definitely benefit, but then again, I have a job that deals with teachers all day long, and there are not many people who want to do it. ”

Yes, this is equivalent to not saying it.

Han Bin searched the storage room carefully, but did not find any obvious clues, and ordered, "Leave two people to keep an eye on, wait for the people from the technical department to come over, and the others will follow me to the monitoring room." ”

Xiaoyan and Dahan were left behind, watching everyone leave.

Han Bin took a few steps and stopped, "Is there a back door here?"

"Yes. ”

"Took us out the back door. ”

Dead people can't walk, and how the suspect transported the body out is also one of the issues that Han Bin is considering now.

It is necessary to find out the topography of the teaching and research building.

Out of the teaching and research building, Han Bin went around the school again and figured out the structure and topography of the school.

Only then did he follow Ma Tao to the monitoring room.

In addition to the teaching and research building, the other monitoring equipment was previously installed, and it can only store half a month's surveillance video, in other words, only the surveillance video in the teaching and research building can be used.

Han Bin asked people to call up the monitoring of the main entrance, hall, corridor on the second floor, and back door of the teaching and research building, and everyone began to check the video separately.

In order to improve the efficiency of viewing the video, Han Bin reminded, "The time when the female body was stolen was the night of July 16, you can check whether the surveillance video of that night is abnormal." ”

After a while, Bao Xing shouted, "Team Han, there is a situation on my side, the surveillance camera in the corridor is blocked." ”

Han Bin leaned over to the screen, "Is the blocking tight, and has the suspect been photographed?"

Bao Xing watched all the videos before and after the blocking, and slowed down the video, "I didn't find anything, and the blocking was very tight." ”

Han Bin straightened up, "You play it back again and see how he blocked the camera." ”

Bao Xing played the video backwards, slowed down the video playback again, and stared at the screen with his eyes, "Balloon, it seems that the balloon is blocking the camera!"

Han Bin's gaze swept to the others, "The rest of you also check the surveillance that night, except for the storage room and the corridor, which cameras are blocked. ”

Everyone began to look separately, but Han Bin took out a paper and pen and drew a general topographical map of the teaching and research building.

After a while, Yanzi shouted, "On my side, the surveillance at the back door of the teaching and research building has also been blocked, as if it ...... It is also covered with balloons, which look like they are red. ”

Han Bin drew a stroke on the topographic map of the teaching and research building, connecting the storage room, the corridor and the back door, and basically knew the suspect's theft route.
