Mario Casey The backstory: Wauwatosa's city assessor reported that several pieces of mail containing checks had been stolen from a U.S. Postal Service mailbox outside City Hall. The suspect's car - a red Chrysler - was seen near the mailbox on nine different occasions, eight of which happened in March, between 2 a.m. and 4 a.m., according to a criminal complaint. One person would get out of the driver's door, sometimes joined by a passenger. They'd go over to the mailbox, use a mail key to open it, and remove the mail. Police determined more than $100,000 was stolen. Wauwatosa police set up an operation to arrest the suspect on April 4. The red Chrysler pulled into the City Hall parking lot and stopped at the mailbox shortly after 3 a.m. Mario Casey was alone in the car and was arrested. An officer found the mailbox key in his jacket pocket.
