Third Watch is an American television drama series which first aired on NBC from 1999 to 2005 and followed the lives of an ensemble cast of characters portraying police officers of the New York City Police Department (NYPD) and firefighters and paramedics of the New York City Fire Department (FDNY). Chronology of the characters along the series Maurice 'Bosco' Boscorelli Maurice Louis "Bosco" Boscorelli is a fictional NYPD police officer on the television series Third Watch. He was played by Jason Wiles. 'Bosco' was one of the few cast members to stay on the show for its entire six season run. Only his mother and his girlfriends ever call him "Maurice", while his brother calls him "Mo"; otherwise, he is known as "Boz", "Bosco" or "Boscorelli" to everyone else.

As an officer, Bosco tends to behave as a stereotypical macho "hard ass" male, ignoring "boring" calls in favor of wanting top jobs to play "super cop" on, staking out crime hotspots to watch suspects scope out cars and waits for a theft to occur so he could then charge in and make an arrest. He shows a disregard for orders, often ignores the radio, and puts his best friend and police partner Faith Yokas into difficult situations with him; leading to regular trouble with colleagues and superiors.
