Qingdao Medical College.
When Han Bin and the others arrived at the school, they were greeted by Wang Jinliang, the deputy director of the Academic Affairs Office, and Ma Tao, the director of the Anatomy Teaching and Research Office.
Guo Tianxu gave them a brief introduction.
Wang Jinliang took the initiative to shake hands with Han Bin. "Captain Han, sorry for not recognizing you."
"Director Wang, you're welcome." Han Bin shook hands with him and suggested, "We'd like to go to the crime scene."
"Sure, this way please."
Under Wang Jinliang's lead, the group once again arrived at the storage room of the teaching and research building.
As soon as they entered the second floor of the basement, the surrounding air pressure felt low. Under the dim light, Yanzi, Small Eye, and Big Fool all looked a little grim.
Han Bin and the other two didn't seem to have changed much. Most of the cases they handled were murder cases, and they had seen all kinds of deaths. They had far more contact with the dead than the police officers in the police station.
Along the way, Han Bin observed the cameras. He found that there were surveillance cameras at the entrance of the teaching and research building, the hall, and the corridor on the second floor of the basement. These cameras might have captured the suspect.
When they walked to the door number 207, Ma Tao stopped. "This is the storage room where the cadavers are kept."
Han Bin asked, "Were you the first to find out that the cadavers were stolen?"
"Yes."
"Was the door of the storeroom closed or open at the time? Did the lock show any signs of damage?"
Ma Tao thought for a moment. "I didn't pay much attention to it at the time. I just opened the door normally and didn't find anything unusual."
Han Bin took out the police flashlight and carefully looked at the lock. There were no obvious signs of it being pried open, which meant that the suspect either had a key or a professional lock picking tool.
"Who has the key to this door?"
Ma Tao answered, "I have a key here, and the rest are in the General Affairs Office. I'm not sure how the General Affairs Office keeps the keys. "
Han Bin turned to look at Wang Jinliang. "Director Wang, are you from the Academic Affairs Office?"
"Yes, I'm the deputy director of the Academic Affairs Office."
Han Bin retorted, "I remember that logistics should be managed by the General Affairs Department. Why are you here instead of the people from the General Affairs Department?"
Ma Tao took over the conversation. "The general affairs department is in charge of the logistics, but they don't care about the cadavers. I'm in charge of them alone. After all, most people are afraid of them. Director Wang is mainly responsible for the students' curriculum arrangements. Anatomy classes are usually coordinated and arranged by both of us. "
Han Bin nodded. "Then I'll have to trouble the two of you to contact the General Affairs Department. I want to know how the key to this storeroom is kept."
"Sure, I'll contact them." Wang Jinliang didn't want to stay here, so he found an excuse to leave first.
Han Bin then looked at Ma Tao, "Director Ma, how do you usually keep that key?"
"Clatter …" Ma Tao shook the round key ring in his hand, which was full of keys. Each key was covered with white tape with the house number written on it.
"My keys are locked in a drawer. I always carry the key in that drawer with me. Because I have more keys, I'm more careful. I can guarantee that the key has never been lost or used by others."
Han Bin opened the door with gloves on, and a strong smell of medicine hit his nose. "Oh my god, it really chokes my nose."
Ma Tao explained, "Human organs decay easily, so they can only be soaked in medicine to preserve them."
Han Bin turned his head and told everyone, "Don't touch anything in the room. Sister Li, call the technical department and ask them to come and investigate the scene."
"Yes."
After entering the storeroom, Han Bin looked at the environment inside. The room was full of glass jars with all kinds of organs in them. 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. "Generally, the camera is installed facing the door, so the thief can be captured as soon as he enters the door. The camera in this storeroom is facing inside. After the thief comes in, he can completely block the camera and enter the storeroom to steal. Didn't you feel awkward when you installed the camera? "
"We didn't think too much about it. At that time, to save money, we asked the school's maintenance staff to install it. They thought that it would be more economical to wire it. After that, I also found it a little awkward, but the surveillance had been installed and used normally. If we reinstalled it, we would have to report it, and it was not a matter of the same department … That's it. "Ma Tao's tone was a little helpless.
Han Bin didn't care whether his helplessness was real or he was afraid of trouble.
"In addition to the male cadaver, was there anything else stolen?"
"I don't think so."
"Give me an accurate answer."
"I found that the cadaver was missing, and I panicked. I didn't have time to check carefully." Ma Tao began to check in the storeroom as he spoke.
After a while, Ma Tao said with certainty, "Nothing else was lost."
"Are there any extra items?"
"No."
"Are there any signs that the other items in the storage room have been moved or touched?"
"I don't think so."
"Do you have any suspects for the theft of the cadaver?"
Ma Tao sighed. "I don't think so."
"Who will benefit from this?"
"How should I put this? If I'm dismissed, the person who replaces me will definitely benefit. But then again, I deal with cadavers all day long, and not many people want to take my job."
Well, this was as good as not saying anything.
Han Bin searched the storeroom carefully and did not find any obvious clues. "Leave two people to keep an eye on it and wait for the people from the technical department to come. The rest of you, follow me to the surveillance room."
Small Eye and Big Fool were left behind, and they watched the crowd leave.
Han Bin took a few steps and stopped. "Is there a back door here?"
"Yes."
"Take us out from the back door."
The dead could not walk. How the suspect transported the body was one of the questions that Han Bin was considering now.
It was necessary to understand the layout of the teaching and research building.
After leaving the teaching and research building, Han Bin walked around the school again to figure out the structure and terrain of the school.
Then, he followed Ma Tao to the surveillance room.
Other than the teaching and research building, the other surveillance equipment had been installed before and could only store half a month's worth of surveillance footage. In other words, only the surveillance footage in the teaching and research building could be used.
Han Bin asked someone to pull up the surveillance footage at the entrance of the teaching and research building, the hall, the corridor on the second floor, and the back door. Everyone began to look at the footage separately.
In order to improve the efficiency of looking at the footage, Han Bin reminded them, "The female body was stolen on the night of July 16th. You can check the surveillance footage that night to see if there is anything unusual."
After a while, Bao Xing shouted, "Captain Han, I have a situation here. The surveillance camera in the corridor is blocked."
Han Bin moved closer to the screen. "Is the blocking tight? Did you capture the suspect's figure?"
Bao Xing watched the footage before and after it was blocked and slowed down the speed of the video. "I didn't find anything. The blocking is tight."
Han Bin straightened up. "Replay it again and see how he blocked the camera."
Bao Xing rewound the video and slowed it down again. His eyes were glued to the screen. "Balloon! It seems like the balloon blocked the camera!"
Han Bin glanced at the others. "The rest of you check the surveillance footage that night. Other than the storage room and the corridor, which other cameras were blocked?"
Everyone began to look at the surveillance footage separately. Han Bin took out a pen and paper and drew a rough topographic map of the teaching and research building.
After a while, Yan Zi shouted, "On my side, the surveillance camera at the back door of the teaching and research building is also blocked. It seems … it was also blocked by a balloon. The balloon looks red."
Han Bin drew a line on the topographic map of the teaching and research building, connecting the storage room, corridor, and back door. Basically, he knew the suspect's route of theft.
