Detective from the future

Chapter 705 Clues
Qindao Medical College.

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

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, sorry for your disrespect."

"Director Wang, you're being polite." Han Bin shook hands with the other party, and suggested, "We want to go and have a look at the scene."

"Okay, this way please."

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

As soon as they entered the second floor of the basement, the surrounding air pressure felt low. Under the dim light, Yanzi, Xiaoyan, and Dahan all looked a little dignified.

The three of Han Bin did not change much. Most of the cases they handled were homicide cases. They had seen all kinds of death methods, and they had far more contact with the dead than the police at the police station.

Along the way, Han Bin was watching the cameras. He found that there were surveillance cameras at the entrance of the teaching and research building, in the lobby, and in the corridor on the second floor of the basement. These cameras might have caught the suspect.

When everyone walked to the house number 207, Ma Tao stopped, "This is the storage room for Mr. General."

Han Bin asked, "You were the first to discover that Teacher General was stolen?"

"Yes."

"Whether the door of the storage room was closed or open at that time, is there any sign of damage to the door lock?"

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

Han Bin took out a police flashlight and checked the lock carefully, but there was no obvious sign 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 others are in the General Affairs Department. I don't know how the General Affairs Department keeps them."

Han Bin turned his head and looked at Wang Jinliang, "Director Wang, are you from the Office of Academic Affairs?"

"Yes, I am the deputy director of the Academic Affairs Office."

Han Bin asked back, "I remember that 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, "The logistics is indeed managed by the General Affairs Office, but generally the teachers don't care about it, and I am responsible for it alone. After all, most people are afraid of this thing. Director Wang is mainly responsible for the curriculum arrangement of the students, and the anatomy class is generally in charge. It was the two of us who coordinated and arranged."

Han Bin nodded, "Then both of you, please contact the General Affairs Office. I want to know how the key to the storage room is kept."

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

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

"Wow..." Ma Tao shook the round key ring in his hand. It was covered with keys, each key was pasted with white tape, and the house number was written on the tape.

"My keys are all locked in a drawer. I always carry the keys in that drawer with me. Because there are many keys, I pay more attention. 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 nostrils, "Good guy, it really chokes your nose."

Ma Tao explained, "Human organs are prone to corruption, so they can only be soaked in liquid medicine to preserve them."

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

"Yes."

After entering the storage room, Han Bin looked at the environment inside. The room was full of glass jars containing various organs. If a timid person came in, he would be scared to death.

Han Bin's eyes fell on the surveillance camera above the door, and he frowned slightly, "General cameras are installed facing the door, and the thief can take pictures as soon as he enters the door. The camera in this storage room faces inside, and the thief After entering, you can completely cover the camera and then enter the storage room to steal, don't you feel awkward when the camera is installed?"

"We didn't think too much about it. In order to save money, we asked the school's maintenance personnel to install it. They thought it would save more wiring. Afterwards, I also found it a bit awkward, but the monitoring has been done and it is in normal use. If it is re-installed, it needs to be reported, and it is not a matter of a department... It will be like this later." Ma Tao's tone was a little helpless.

Han Bin didn't bother to care whether his helplessness was real or whether he was afraid of trouble.

"Apart from the male general teacher, was anything else stolen?"

"should not."

"Give me an accurate answer."

"I found that the general teacher was missing, and I was in a panic. I didn't bother to check it carefully." Ma Tao began to check in the storage room.

After a while, Ma Tao said firmly, "I didn't throw anything else."

"Are there any extra items?"

"No."

"Is there any other item in the storage room that has been moved or touched?"

"Not in my impression."

"Are you suspicious about the theft of Teacher General?"

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

"Who will benefit from this?"

"How should I say this? If I am dismissed, the person who replaces me will definitely benefit. But then again, my job is dealing with the general teacher all day long, and not many people want to do it."

Well, it's like saying nothing.

Han Bin searched the storage room carefully, but found no obvious clues, and ordered, "Leave two people to watch, wait for the people from the technical department to come, and the others will follow me to the monitoring room."

Xiaoyan and Dahan were left behind, watching the crowd leave helplessly.

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

"Have."

"Take us out the back door."

The dead can't walk. How the suspect transported the corpse out is also one of the issues Han Bin is thinking about now.

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

After leaving the teaching and research building, Han Bin went around the school again, and got a clear idea of ​​the structure and topography of the school.

Then he followed Ma Tao to the monitoring room.

Except for the teaching and research building, other surveillance equipment was installed before and can only store half a month of surveillance video. In other words, only the surveillance video in the teaching and research building can be used.

Han Bin asked people to call out the surveillance cameras at the main entrance, lobby, second-floor corridor, and back door of the teaching and research building, and everyone began to watch 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 7. You can check the surveillance video of that night to see if there is any abnormality."

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 cover tight? Did you capture the suspect's figure?"

Bao Xing watched the video before and after the blocking, and slowed down the video speed, "I didn't find anything, the blocking is very tight."

Han Bin straightened up, "Play it back again to see how he blocked the camera."

Bao Xing played the video backwards, slowing down the playback speed of the video again, his eyes fixed on the screen, "Balloon, it seems that the balloon is blocking the camera!"

Han Bin glanced at the others, "The rest of you also check the surveillance that night. Apart from the storage room and corridor, which camera is blocked."

Everyone began to check separately, while Han Bin took out a pen and paper and drew a rough 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 was also blocked, as if... it was also blocked by a balloon, and the balloon looked like it was 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, basically clearing the suspect's theft route.
