Incident Report: On May 2, 2021, at approximately 12:45PM, Ms. Shea returned from her lunch break to discover that her jar of raffle tickets was missing from her desk and a mysterious note was left in its place. The authorities have been notified and will be arriving on the scene shortly to collect evidence. They don't have much information yet, but because Ms.Shea's classroom door was locked when she left, the police have a hunch that the thief is someone with access to her keys or classroom. They have begun compiling a list of potential suspects, but they will need the help of an elite Forensic Science unit to narrow down the suspect list and hopefully track down the raffle ticket thief.
