"The record has been deleted! What should I do? I'll find someone to restore it."
Zhan Yi couldn't help but frown, and the record was deleted. It was really planned long ago.
"It seems to have been forcefully deleted, and it seems difficult to recover." The teacher who helped adjust the monitoring frowned and shook his head.
"Boss, why aren't you in a hurry?"
Zhan Yi was still thinking about whether to find a professional to take a look. When he turned to look at Ye Bai, he saw Ye Bai sitting leisurely on the chair, as if it didn't matter to him.
"Why are you anxious? The records have been deleted, why should I be anxious?" Ye Bai shrugged, saying that he was also anxious, but it seemed that no matter how anxious he was, it was of no use.
"It's just that the surveillance records have been deleted, so we should be anxious! Not to mention locking in the suspect, we won't even know when the suspect committed the crime."
Zhan Yi really felt a headache, as if this matter was not so simple and he could get along with it.
"We don't need to know when the crime was committed. It's meaningless. Anyway, it was from the time after the holiday on Friday to Sunday."
"It doesn't matter at what point it was done."
Ye Bai was still very calm, she didn't focus on the surface, her thoughts were deeper.
"That's true, but the key point is that the surveillance records have been deleted, isn't it?"
Zhan Yi actually still didn't understand what Ye Bai meant by what he said just now: "Without the record, wouldn't we have lost all clues?"
"That's impossible to say."
Ye Bai's lips curled up slightly and he said something meaningful.
"Who said there were no clues?"
Um
Zhan Yi looked at Ye Bai with some confusion. Could it be that the information he and Ye Bai received were different
For Ye Bai, the key to this whole thing is not who did it, but who deleted the record.
As long as you can find this person, you can easily find out who did this.
Comparatively speaking, the person who deleted this monitoring record is relatively easy to find.
"Does your work in the monitoring room ensure that there is someone at every time?" Ye Bai curled his lips, looked at the two people who were helping to investigate and monitor, and asked an unclear question.
"Yes." The two men looked at Ye Bai and replied. They didn't know what Ye Bai meant by asking this question.
Ye Bai reached out and took out a schedule they had taped on the wall and shook it: "It's very clear who deleted the surveillance records."
Zhan Yi looked over the schedule from Ye Bai's hand for a long time, but didn't see anything.
"Do you mind lending me a piece of paper and a pen?"
Ye Bai felt that it seemed more complicated to explain directly, so it would be clearer if he wrote it down.
After successfully using pen and paper, Ye Bai began his own analysis and calculation.
"Judging from the schedule, there are eight staff members in the control room, working in pairs, for a total of four groups."
"Replace the eight people with the letters A to H. AB, CD, EF, and GH are fixed groupings, and their duty hours are also fixed at three time points, which are morning shift 6:00-14:00, The afternoon shift runs from 14:00 to 22:00, and the last night shift is from 22:00 to 6 a.m. the next day.”
"Judging from the shift schedule, from the beginning of the shift change after the holiday on Friday afternoon to now, there are 8 shifts."
Ye Bai analyzed everything in an orderly manner.
