The suspect's whereabouts after entering the teaching and research building were basically known.
However, the surveillance outside the teaching and research building could only be kept for half a month. It was impossible to trace the suspect's whereabouts outside the building through the surveillance.
The biggest problem in stealing a corpse was how to transport it out.
Transporting it from the storage room out of the teaching and research building was one stage, and transporting it out of the school was another.
Moreover, this case was not as simple as a theft.
The female cadaver could not have appeared out of thin air. It should have been transported to the school from outside and placed in a formalin pool for a period of time, waiting for the body to be embalmed before being moved away.
This behavior was somewhat intriguing. What was the suspect's ultimate goal?
If it was purely for embalming, he could have found a hidden place. Why did he have to transport it to the school?
How did the suspect transport the body to the school and then transport it away?
Han Bin felt that the suspect was either extremely daring or had a mole in the school.
"Dean Ma, are there many people on campus in July?"
Ma Tao thought for a moment. "Aiyo, I'm not sure about that. The situation of each department is quite complicated."
"Dean Ma, you should have noticed that this is not a simple case of theft. It may be more complicated than we thought. I want to have a more comprehensive understanding of the school and would like to meet the school's senior management."
Ma Tao smiled bitterly. "I can't make the decision. I need to report to the school's leaders."
"It's my duty." Han Bin took out a business card. "My phone number is on it. You can contact me directly."
"Okay." Ma Tao took the business card, greeted everyone, and then left the monitoring room.
After that, Han Bin also left the surveillance room and returned to the back door of the teaching and research building with Guo Tianxu and Bao Xing. Li Qin and Yanzi stayed in the surveillance room to continue watching the video to see if they could find more clues.
Han Bin returned to the back door of the teaching and research building to see if the suspect had left any clues. Secondly, he wanted to check the suspect's route in and out of the school.
Han Bin set off from the entrance of the teaching and research building and walked around the school. He did not find any obvious traces.
In fact, it was normal. More than a month had passed. Even if there were any clues, they would have been destroyed.
"Captain Han, you're here. I finally found you." Wang Jinliang, the Deputy Director of the Academic Affairs Office, walked over while panting. Beside him was a woman in her forties.
"Let me introduce you. This is Director Sun Yuefen of the General Affairs Department."
Sun Yuefen took the initiative to greet him, "Hello, Captain Han."
Han Bin said politely, "Director Sun, sorry to trouble you to make a trip here."
Sun Yuefen was straightforward. "Of course. It's all for the school. If you have anything to say, just say it."
"Does the General Affairs Department have a copy of the key to storage room No. 207 on the second floor of the teaching and research building?"
"Yes, we have a backup of the keys to most of the rooms in the school."
"Where are the keys kept?"
"There is an office in the General Affairs Department that is used to store keys and information. The office door is usually locked, and the security measures are very tight."
"Do you still have the key to Room 207?"
Sun Yuefen took out four keys from her pocket. "Yes. I heard about it from Director Wang, so I brought the keys. There are four keys in total. Including Director Ma's key, there are five."
Han Bin handed the keys to Bao Xing. "Go and see if it works."
Bao Xing took the keys and ran away.
Han Bin asked, "Director Sun, is there anyone on duty in the General Affairs Department during the holidays?"
"Yes, the General Affairs Department is in charge of a lot of things. We can't do without people. Usually, there are one or two people on duty. "
Han Bin nodded. Just like what Ma Tao said, there were many departments in the school. Each department had a different division of labor. Most of them had employees on duty, so it was difficult to keep track of them.
"Ring ring ring …" At that moment, Han Bin's phone rang.
Han Bin took out his phone and saw an unfamiliar number on the screen.
"Hello, I'm Han Bin."
"Captain Han, I'm Ma Tao. I'm at the Administration Building. Principal Chen Huafeng, who is on duty today, heard that you came to the school to investigate a case. He also wants to meet you."
"Okay, I still have something to do here. I'll go to the Administration Building when I'm done."
After explaining the situation, Han Bin hung up.
Wang Jinliang said, "Captain Han, why do you want to go to the Administration Building?"
"Principal Chen Huafeng wants to meet me."
Wang Jinliang persuaded, "Oh, then hurry up. We'll wait here for Officer Bao."
Sun Yuefen also added, "Captain Han, you go ahead. We'll wait here."
Han Bin nodded, "Then I'll have to trouble you two."
"You're welcome."
Han Bin sent a message to Bao Xing to explain the situation and then went to the Administration Building with Guo Tianxu.
Principal Chen Huafeng looked about fifty years old. He wore a pair of gold-rimmed glasses and had a faint smile on his face. He had a scholarly temperament and was very enthusiastic when he saw Han Bin.
"You must be Captain Han. You're young and promising. Please come in." Chen Huafeng led Han Bin and Sun Yuefen into the office and invited them to sit on the sofa.
Chen Huafeng's office was very simple. What impressed Han Bin the most was that there were a lot of books. The two cabinets were filled with books and there were two thick stacks of books on the desk.
After introducing each other, Ma Tao left the office, leaving only Han Bin and the other two in the room.
"Captain Han, I heard from Director Ma about the general situation. If there's anything you need, please let me know. The school and I will do our best to help."
"Thank you." Han Bin did not stand on ceremony and went straight to the point. "I want a list of the on-duty personnel during the school's vacation."
Chen Huafeng frowned slightly, "Is it limited to the Teaching and Research Building or do you want a list of all the on-duty personnel who come to the school?"
"A list of all the on-duty personnel who come to the school."
Chen Huafeng sighed, "The school's vacation period is longer this time. Each department has their own arrangements and responsibilities. There are also more on-duty personnel. This is a big project."
Han Bin said, "It's because it's not easy. That's why I'm troubling you. If it's a small matter, I'll ask Director Ma and Director Wang to help me."
"Okay, I'll inform each department to submit a list of on-duty personnel. However, I'm afraid it will take some time."
"It's okay. You can contact me when it's ready."
"Okay." Chen Huafeng responded, "Do you have any other requests?"
Han Bin thought for a moment, "Does your school hire anyone with a criminal record of theft?"
Chen Huafeng's tone was firm, "No. Our school's teachers have to go through a strict review of their education and background. If they really have a criminal record, we won't use them."
Han Bin explained, "I'm not just talking about teachers. It also includes other staff such as cleaners, security guards, kitchen staff, etc. Everyone who works in the school is included."
Chen Huafeng scratched his chin, "This … I'm really not sure."
"Then, please help me verify it."
Chen Huafeng nodded, "No problem. I'll ask the personnel department to help with the investigation."
Han Bin changed the topic, "Has your school ever had a theft case before?"
"How should I put this? There are more students in the school and the situation is more complicated. Petty theft is inevitable, but it's the first time a cadaver has been stolen. "
"How did the male cadaver come about?"
"The cadaver was donated."
Han Bin suggested, "I need a copy of the male cadaver's information."
"No problem. I'll ask Director Ma to send it to you later."
Han Bin asked a few more questions, but he didn't get any more clues, so he took his leave.
As soon as he left the administrative building, he saw Bao Xing standing at the door smoking.
Bao Xing extinguished his cigarette and walked over, "Captain Han, Officer Guo, I tried opening the door with the keys. All four keys worked, and they should be original keys. There's no problem."
"I met Director Sun from the general affairs department on my way back, so I returned the keys to her."
Han Bin nodded, "Are the people from the technical department here?"
"Yes, they're investigating the scene."
Han Bin returned to the storage room on the second floor of the teaching and research building. There were a total of three people from the technical department, led by Ma Xiwen. He looked to be in his thirties, wore thick glasses, and was a little bald.
"Brother Ma, did you find anything?"
Ma Xiwen pushed his glasses with his elbow, "There are no obvious footprints at the scene, but we collected some fingerprints. We're going to take them back for comparison."
"In addition, we extracted the embalming fluid from the pool, and we'll take it back for testing."
Han Bin thought about it and said, "Some of the school's surveillance videos can only be stored for half a month, but the suspect's theft happened a month ago. Can we try to recover the previous video?"
Ma Xiwen pursed his lips, "We'll try, but the possibility of recovery is not high, and the clarity of the video will be affected."
"Thank you."
