"Thanks to the fact that it's daytime," Chen Feng hugged his arms and shuddered, "If it's night, I'll be scared by Team Ning's description." Pen Fun Pavilion www.biquge.info" Song Ming bumped Chen Feng with his shoulder and said, "Why are you getting smaller and smaller?" How soon to catch up with Jiang Xue. Ning Zhiyuan interrupted the frolic between the two and said, "Song Ming, you and Da Yang go to the operating room to ask the staff on duty yesterday, and ask Xiao Yuping every detail after he came out of the operating room." Chen Feng and I will go to the security department to watch the surveillance first, and when you are done, go there to meet us. ”

Ning Zhiyuan and Chen Feng came to the security department of the central hospital, just in time for the security officer Lao Liu to be on duty. The two explained their intentions, and Lao Liu hurriedly transferred the monitoring archive of the outpatient building to the screen of the outpatient hall before Xiao Yuping jumped off the building last night. Not long after, Xiao Yuping appeared in the picture. She entered through the main entrance of the outpatient building, with her hands in the pockets of her white coat, and walked quickly in the direction of the elevator hall, without any pause or hesitation.

Lao Liu adjusted the picture to the elevator again, Xiao Yuping did not press the floor button after getting on the elevator, but waited until he was almost down to press the number on the top floor. After the elevator reached the top floor, Lao Liu switched the picture again, Xiao Yuping walked out of the elevator and went straight to the stairwell, from where the door to the top of the building could be seen on the upper half of the stairs. Unfortunately, there were no surveillance cameras installed there, so Xiao Yuping disappeared after entering the stairwell.

"Is the door at the top of the building locked?" Ning Zhiyuan asked Lao Liu. Lao Liu nodded and said, "It's locked, the key is in our security department, and it will only be opened when the facilities on the roof need to be repaired." Ning Zhiyuan thought for a while and asked, "Have you repaired the facilities on the roof recently?" Lao Liu thought for a moment: "Some time ago, the neon sign was not very easy to use, and the installation company sent someone to repair it, and it took about two days to repair. ”

Ning Zhiyuan frowned: "When is it?" "It seems like half a month ago." Lao Liu thought about it and said, "After they repaired it, they sent the key back, and I went up to check it, the door was locked, and after that, no one came to get the key." Ning Zhiyuan took out a notepad and asked Lao Liu: "Do you know which installation company it is?" Is there their address and contact details? "No," Lao Liu shook his head, "The logistics side is responsible for these things, and that day they also called to say that someone from the installation company was coming to get the key to the roof." Why don't I ask the logistics guys? "Okay, then I'll bother you." Ning Zhiyuan said with a slight smile at Lao Liu.

The old man went to the desk next to him to make a call, and Ning Zhiyuan switched the monitoring screen to the outpatient hall again, and adjusted the time to half an hour before Xiao Yuping came in. There are many fewer people in the hall than in the morning, and there are no queues at the registration and collection windows, and occasionally people go to the collection office to pay the money. From the screen, you can see that the financial staff in the window has already begun to prepare before leaving work.

After 10 p.m., the hall was filled with more people. Although these people were dressed in civilian clothes, it was clear from the walking route that the day shift outpatient doctors of each department and the staff of each administrative department were off duty. People walked out of the outpatient building in groups of three or five, everything looked so normal, if they knew that someone would jump off the roof in about half an hour, would they still be so calm?

Until Xiao Yuping entered the screen, there was nothing unusual in the hall. Lao Liu handed a note with an address and phone number to Ning Zhiyuan: "Captain Ning, this is the address and phone number of the light box installation company." Ning Zhiyuan took the note and glanced at it, and put it in a notepad: "Thank you, Lao Liu." Please call up the monitoring of several other entrances to the outpatient building, and the time will start at half past four yesterday afternoon. ”

In addition to the main entrance, there are two entrances to the outpatient building of the city center, one is the back door across the hall from the main entrance, which leads to the backyard of the hospital, which is where the dormitory and boiler room are located. The other is a fire escape located on the side of the building. Outside the fire escape is a small road that can accommodate two vehicles side by side.

When Ning Zhiyuan and Chen Feng finished watching the surveillance at the back door and switched the screen to the fire escape, Song Ming and Dayang also came. Lao Liu enthusiastically moved the two chairs and said, "You guys take your time first, I'll go get some boiling water." Song Ming sat down next to Ning Zhiyuan and whispered, "We asked the person on duty in the operating room yesterday, Xiao Yuping has been quite normal when he had surgery yesterday afternoon. One nurse said that after she came out of surgery, she turned on her phone in the locker room and a text message came in, and she sat there and sent it for a while. The nurse also asked her if she was tired from the operation, and she said that she was a little tired and that she would have to go back and have a good rest. Later, someone came to inform her to go back to the department immediately, and she got up and left. ”

"Text message? That's an important piece of information. Ning Zhiyuan glanced at Song Ming, "Is there anything else?" "No," Song Ming shook his head, "Xiao Yuping didn't have a long time from coming out to leaving the operating room. "Team Ning, look." Chen Feng, who had been staring at the monitor screen, suddenly said, "This person looks a little strange. ”

The surveillance footage shows a person entering the outpatient building through the door of the fire escape. A black ankle-length down jacket envelops the whole person. Upon entering the building, the man removed the down jacket and hat from his head, revealing his head wearing a peaked cap with a brim pressed so low that the man's eyes were largely invisible from the monitor's perspective. Wearing a mask, the lower half of his face is also tightly covered. The whole person really looks like a person in a suit. He was carrying a large black bag, which seemed to be weighing a bit from his gait.

After entering the outpatient building, the person walked directly into the stairwell. There was no monitoring equipment in the stairs, so Ning Zhiyuan had to wait until Lao Liu came back from fetching water, and then called up the monitoring of each floor one by one. After checking layer by layer, this person's figure has not reappeared. "Damn, I must have gone straight to the roof." Chen Feng slapped the table. "Switch back to the fire escape, and push back twenty minutes." Ning Zhiyuan said to Lao Liu.

The surveillance footage returned to the door of the fire escape, and all eyes were focused on the screen of the monitor. Time passed little by little, and finally the black figure reappeared in the surveillance footage. Ning Zhiyuan looked at the time on the monitor, it was about ten minutes after Xiao Yuping jumped off the building. "Quick, cut to the camera in front of the hospital." Song Ming said to Lao Liu with some excitement. (To be continued.) )
