We continued to pull tapes, steadily closing in on when the crime occurred until we narrowed it down to around 3 p.m. on a Wednesday. So we loaded the final tape and settled back to catch the thief in the act.
As the tape played, we saw team members leaving the area, one at a time, to go to a meeting until the entire area was empty. It was the perfect opportunity for our criminal.
Then, at 3:17 p.m., the modem was suddenly gone, having disappeared before our eyes with no perpetrator in sight. Was this an X-Files thief with superhuman speed? Only after replaying the tape in slow motion did we discover the truth: I watched in horror and embarrassment as the modem rocked slightly in the air-conditioning breeze, then slid smoothly off the back of the PC and down behind the desk.
There was no thief, only a messy desk and gravity at work. Red-faced, I frantically apologized to the physical security team before rushing to the desk, where, sure enough, I found the modem hanging in the back in a mess of wires.
