Detective from the future

Chapter 706
The whereabouts of the suspect after entering the teaching and research building were basically found out.

However, the monitoring outside the teaching and research building can only be kept for half a month, and the whereabouts of the suspect outside the teaching and research building cannot be found through monitoring.

The biggest problem with stealing corpses is how to get them out.

Moving out of the teaching and research building from the storage room is one stage, and moving out of the teaching and research building from the school is another stage.

Moreover, this case is not as simple as theft.

It is impossible for the female teacher surnamed General to appear out of thin air. It should have been transported to the school from outside, and placed in the formalin pool for a period of time, and then moved out after the corpse was embalmed.

This behavior is somewhat intriguing. What is the ultimate goal of the suspect?
If it's just for anti-corrosion, just find a hidden place, so why bother to bring it into the school?

How did the suspect transport the corpse into the school, and then transport the corpse away?

Han Bin felt that the suspect was either audacious or had internal support in the school.

"Director Ma, are there many students on campus in July?"

Ma Tao thought for a while, "Hey, I really don't know much about this. The situation of each department is also complicated."

"Director Ma, you should have noticed that this case is not a simple theft case. It may be more complicated than we imagined. I want to have a more comprehensive understanding of the school and want to meet the senior leaders of your school."

Ma Tao showed a wry smile, "I can't decide this situation, I need to report to the school leaders."

"It should." Han Bin took out a business card, "It has my phone number on it, you can contact me directly."

"Okay." Ma Tao took the business card, greeted everyone, and left the monitoring room.

After that, Han Bin also left the monitoring room, and took Guo Tianxu and Bao Xing back to the back door of the teaching and research building, while Li Qin and Yanzi stayed in the monitoring room and continued to check the video to see if they could find more clues.

Han Bin returned to the back door of the teaching and research room, first to see if the suspect had left any clues, and second, to check the suspect's route in and out of the school.

Han Bin started from the entrance of the teaching and research building and walked around the school, but found no obvious traces.

In fact, it's normal to think about it. More than a month has passed, and even if there are clues, they are almost destroyed.

"Captain Han, you are here, I finally found you." Wang Jinliang, the deputy director of the Academic Affairs Office, walked over panting, followed by a 40-year-old woman.

"Let me introduce you, this is Director Sun Yuefen of the General Affairs Department."

Sun Yuefen took the initiative to say hello, "Captain Han, hello."

Han Bin said politely, "Director Sun, please make a special trip."

Sun Yuefen spoke very frankly, "It should be, it's all for the school's business, if you have anything to say, just say it."

"The key to the storage room No. 207 on the second floor of the Teaching and Research Building, do you have a backup in the General Affairs Office?"

"Yes, the keys to most of the school's rooms are backed up in our General Affairs Office."

"Where are the keys?"

"There is an office in the General Affairs Department, which is specially used to store keys and materials. The doors of the office are usually locked, and the storage measures are very strict."

"Do you still have the key to Room 207?"

Sun Yuefen took out four keys that were intertwined with each other from her pocket, "Yes, I heard what Director Wang said, so I brought the keys along, there are four keys in total, including Director Ma's one, exactly five. "

Han Bin handed the key to Bao Xing, "Go and see if it works."

Bao Xing took the key and ran away.

Han Bin took advantage of the situation and asked, "Director Sun, is there any staff in your General Affairs Department on duty during the vacation?"

"Yes, the General Affairs Office manages a lot of things, no one can do it. Usually there will be one or two people on duty."

Han Bin nodded. As Ma Tao said just now, there are many departments in the school, and each department has a different division of labor. Most of them have employees left behind, so it is difficult to count.

"Dinglingling..." At this moment, Han Bin's cell phone rang.

Han Bin took out his mobile phone and looked at it. An unfamiliar number was displayed on the screen.

"Hi, I'm Han Bin."

"Captain Han, I'm Ma Tao. I'm here in the administration building. Principal Chen Huafeng, who is on duty at the school today, heard that you came to the school to investigate the case. He also wants to see 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 the phone.

Wang Jinliang on the side said, "Captain Han, what do you want to do in the administration building?"

"Principal Chen Huafeng asked me to meet."

Wang Jinliang persuaded, "Yo, then you can go quickly, we just wait here for that police officer Bao."

Sun Yuefen also echoed, "Captain Han, you go, we'll wait here."

Han Bin nodded, "Then I will trouble you two."

"You're welcome."

Han Bin sent a message to Bao Xing to explain the situation, and then went to the administrative building with Guo Tianxu.

Principal Chen Huafeng looked about 50 years old, wearing gold-rimmed glasses, with a faint smile on his face, and a bookish temperament. He was very enthusiastic after meeting Han Bin.

"You are Captain Han, right? You are young and promising, please come in." Chen Huafeng led Han and Bin into the office, and invited them to sit on the sofa.

Chen Huafeng's office is very simple, and Han Bin's deepest impression is that there are a lot of books, the two cabinets are full of books, and there are two stacks of thick books on the desk.

After Ma Tao introduced each other, he left the principal's office, leaving only Han Bin and the other three in the room.

"Captain Han, I have heard from Director Ma about the general situation. If you need anything, just tell me. The school and I will do our best to help."

"Thank you." Han Bin was not polite, and said straight to the point, "I would like a list of your school's staff on duty during the vacation."

Chen Huafeng frowned slightly, "Is it limited to the teaching and research building, or is it a list of all those who come to the school on duty?"

"A list of all those who come to the school on duty."

Chen Huafeng sighed, "The school vacation is relatively long this time. Each department has its own arrangements and responsibilities, and there are more people on duty. This is a big project."

Han Bin said, "It's because it's not easy, so I trouble you. If it's a trivial matter, I'll ask Director Ma and Director Wang to help."

"Okay, I'll inform you and let the various departments report the list of on-duty personnel, but I'm afraid it will take some time."

"It's okay, when it's done, you just need to contact me."

"Yes." Chen Huafeng responded, "Do you have any other requests?"

Han Bin thought for a moment, "Does your school hire anyone with a history of stealing?"

Chen Huafeng said in a firm tone, "No, the qualifications and background of our school teachers have to be strictly checked. If there is a criminal record, we will not use it."

Han Bin explained, "I'm not only referring to teachers, but also other staff, such as cleaners, security guards, back kitchens, etc., including all those who work in the school."

Chen Huafeng scratched his chin, "This... I really don't know much about it."

"Then please help me to verify."

Chen Huafeng nodded, "No problem, I will ask the HR Office to assist in the investigation."

Han Bin changed the subject, "Has there been a theft case in your school before?"

"How should I put it? There are more students in the school, and the situation is more complicated. Petty theft is inevitable, but it is generally the first time that a teacher has been stolen."

"How did that male general teacher come from?"

"Donation of remains."

Han Bin suggested, "I need a profile of a male general teacher."

"This is no problem. I will ask Director Ma to send it to you in a while."

Han Bin asked a few more questions, but left without asking any more clues.

As soon as he left the administrative building, he saw Bao Xing standing at the door smoking a cigarette.

Bao Xing snuffed out the smoke and came over, "Team Han, Police Chief Guo, I tried to open the door with the keys, all four keys can open the door, and they should all be original keys, no problem."

"When I came back, I met Director Sun of the General Affairs Department, and I returned the key to her."

Han Bin nodded, "Is the person from the technical department here?"

"Here we are, investigating the scene."

Han Bin returned to the storage room on the second floor of the teaching and research building. A total of three people came from the technical department. The team leader was Ma Xiwen, who looked in his 30s and was already a little bald with a thick spectacle frame.

"Brother Ma, did you find anything?"

Ma Xiwen pushed his glasses with his elbow, "There are no obvious footprints at the scene, but some fingerprints have been collected, and we are going to take them back for comparison."

"In addition, we extracted the antiseptic solution in the pool and will take it back to test the ingredients."

Han Bin thought for a while and said, "Part of the school's surveillance video can only be stored for half a month, but the suspect stole it a month ago. Can you try to restore the previous video?"

Ma Xiwen pursed his lips, "Let's try, but the possibility of recovery is not high, and the video clarity will also be affected to a certain extent."

"Thanks for your hard work."
