We have been called in by Colby’s Security Department to help them recover a PS3 that was stolen from their office at approximately 9:00 PM while the officer on duty was called away from a game of Grand Theft Auto to investigate a potentially illegal gathering in one of the residence halls. The officer noted five suspicious persons on his way out of Roberts. Fortunately, the culprit left behind a clue in the form of a crumb of food. We will conduct an analysis of the snack food eaten by each suspect to try to match it to the culprit’s crumb.
