While Jimmy was struggling with the direction of the investigation, Mark and Wright were not idle either. Although they weren't in charge of the case, they had handled many cases before, so they were quite experienced. Trapped on the island with not much else to do but make phone calls, they both involuntarily worked overtime to re-check the surveillance videos they'd viewed earlier. Then Mark discovered a seemingly insignificant issue in the surveillance.
"Knock knock..." Holding a laptop, Mark got up and went to Jimmy's room to knock on the door. Jimmy walked over, opened the door, and asked, "What's up?"
Mark, looking pleasantly surprised, said, "I found a problem; a surveillance video has been tampered with."
