Management loves to jump to conclusions. But there is that possibility that they were already looking to get rid of the guy. Yes the seriousness of the matter should have been turned over to the police, yes the guy should have the time to explain and understand what was happening to him. Ultimately I would have thought they would have suspended him pending an investigation, and make sure no one talks, then if guilty - Fire his ass and hope he gets lots of PMITA prison time. Otherwise if cleared, make a full apology with back pay, issue a new laptop and let him go about his job.
