The connection line on the surveillance camera was inexplicably disconnected, and it was at the key node before Chen Qian's death, no matter from the time, place or means, it is impossible to cover up with a simple accident, in this case, Li Yiting and Chen Tianyu are even more unlikely to easily learn about Chen Qian's death by suicide.

For Beiting, Chen Qian's death is a relatively simple one of the death cases they have encountered, there is a lot of time interval between the discovery of the body and the investigation of the scene, and although there are no witnesses, there are still people who have seen her shortly before the deceased's death, and the crime scene is easy to determine, and the cause of death has been deduced early, and all kinds of evidence can be connected, and everything is in accordance with the rules. But under Li Yiting's insistence and suspicion, all kinds of contrary doubts emerged one after another, telling them that this was not as simple as a suicide jumping off the building, and the collision of the positive and negative aspects of this entry and exit gave them a little headache.

In order to clear his suspicions, Director Qi did not wait for Li Yiting and them to continue to ask, and said, "The monitoring was found to be broken when I was at work, and then I arranged for someone to overhaul it and restore it in the afternoon." I was at home before I went to work, and I didn't arrive at the unit until almost eight o'clock, and many people can testify that I was not in the hospital before that, so if someone broke the cable, it must have been before eight o'clock, and I didn't have the time to commit the crime. ”

Li Yiting looked at him silently, what Director Qi said was reasonable, since the alibi was provided by himself, there would basically be no problem if he went to verify, otherwise the other party would not ask for trouble. But Li Yiting did not respond to this, the whole Chen Qian jumping case is very weird, there is evidence in any detail, but there are contrary clues, and now everything is unknown. Director Qi's attitude was actually unusual, Beiting didn't say anything, this person was eager to defend himself, which was a manifestation of weakness. Besides, it is true that the connection line was broken before going to work, but it is not necessarily before 8 o'clock in the morning, and it may have broken the night before, when it was the dead of night, who can prove it?

Liu Zichen thought of an idea at this time, "By the way, we can check the fingerprints on the monitoring connection line and see if we can extract clues from relevant personnel?"

Now Li Yiting spoke, but he said that there was no need, "No need, isn't it overhauled? Even if there are fingerprints, they have been destroyed by the restoration personnel, and if someone really deliberately cuts the line, they will not be stupid enough to touch it with their hands and leave traces." ”

"Director Qi, what time is the specific time for monitoring to be bad?" Chen Tianyu on the side suddenly asked.

"It must have been eight o'clock, no, maybe earlier, because I was busy with other things when I went to work, and then I noticed that the surveillance screen was missing the oncology department. Director Qi replied truthfully.

"I need to retrieve all the surveillance footage of the other floors and the hospital gate in the twelve hours before 8 o'clock, and I hope you can cooperate. Chen Tianyu continued.

"Twelve hours?" Director Qi was a little surprised, but he didn't ask much, and immediately agreed, "Okay, no problem, I'll copy it out when I go to the hospital tomorrow." ”

"It's too late tomorrow, go now, thank you. ”

Li Yiting immediately understood what Chen Tianyu meant, he naturally wouldn't wait until tomorrow, the night was long and dreamy, and after this night passed, he didn't know what would happen. And although they secretly brought Director Qi, it is difficult to guarantee that they will not be discovered by other people with ulterior motives, and the current Sixth Hospital gives people the feeling that it is a place of right and wrong, with various interests intertwined, and many things cannot be careless.

Director Qi had no choice but to comply, Li Yiting and Liu Zichen took him again, sat in Director Qi's car, and then returned to the hospital. Bringing him to the Wen family was mainly to allow him to accept inquiries calmly, and also to allow Chen Tianyu and them to communicate with him face-to-face, and now he has really gained something.

On the way, Li Yiting told Director Qi that this matter should still be kept secret, and he could not disclose Beiting's investigation of surveillance to anyone. Although Li Yiting is worried about their behavior, especially the investigation in the hospital office, which has attracted the attention of those who have a heart, it is still necessary to remind appropriately, what should be said on the surface still has to be said, at least let the director and Beiting's hearts be on the same line, after all, the insiders here are all objects worthy of suspicion.

Xiang Wen's home area was very close to the Sixth Hospital, and after a few words, he returned again, and the car came to the entrance of the hospital, and the gate had been closed. Director Qi pressed the car window, and the fat security guard at the door came up, "It's Director Qi, why did you come back so late?"

Director Qi smiled politely, "Lao Yao, I have something left in the unit, come back to pick it up, and help me open the door." ”

"What a ......"

Because it was his own person, the security guard only asked symbolically and opened the door. Li Yiting noticed that the door of the car was closed after work, while the small door next to it was always open, after all, there were family members of hospitalized patients who still needed to enter and exit. That is to say, but whoever wants to enter the hospital, within a dozen hours after work, has to show his head in front of the small door, so that the camera on it should be able to shoot, if it is a car, then there is also monitoring and the security guard should have asked, he secretly noted this.

Director Qi parked the car directly downstairs, and took Li Yiting and Liu Zichen up, the outpatient building at night was empty, and the lights were not turned on, which seemed a little infiltrating. Naturally, they are not afraid, but they feel a little uncomfortable, as if they have a pair of eyes, staring at themselves in the dark, but it is difficult to detect them in the dark.

When Director Qi returned to the office, he went to retrieve the video saved in the computer by himself, however, a shocking scene appeared.

"This, how is this possible?" Director Qi screamed in surprise.

"What's wrong?" asked Liu Zichen.

"All the footage is gone!" Director Qi replied loudly.

Hearing this, Li Yiting chuckled in his heart, and all his doubts became a reality at this moment. He won't believe that this is still a coincidence, how can he say that the automatically saved video is gone?

They watched Director Qi rummage through the computer, and there was indeed no surveillance video, the strange thing was that everything else was still there, and what was lost was only the surveillance record. Li Yiting is no longer suspicious, but sure, this must be a pair of invisible black hands doing the trick, from the damage of the camera to the disappearance of the surveillance, could it be that the surveillance will really provide evidence related to Chen Qian's death?
