managed to save him. What looked like a simple accident was soon revealed to be deliberate - John Parker's quality of life was slipping away and he wanted to die. Eventually, Doc helped his father to die. Doc and Sara later broke up in 2001 when she accepted a job in Philadelphia and he wished to stay in New York. Doc was nominated for "Paramedic Of The Year" in 2002, but was caught on camera (he was being filmed by a documentary crew) performing medical procedures that almost paralyzed a young man. Doc felt guilty over this. Later, when an explosion killed Alex Taylor and Lt Johnson, Doc took the news very badly as his guilt increased. He accepted a promotion to a desk job, but was demoted back down to normal paramedic after beating up the guy whom Alex had replaced on the day she died. Doc left the series in 2004 when a new captain was assigned to the firehouse, replacing Jimmy Doherty. The new captain had a reputation for closing down firehouses. Doc snapped and shot him. He intended to hold him hostage for the length of time it would take a paramedic to reach the neighbourhood if the station was shut down. It soon become apparent that the true cause of Doc's actions, in addition to the sum of all the painful and traumatic events in his life, was his inability to deal with the horror of the September 11, 2001 terrorist attacks, even three years later. Once his good friend NYPD officer John Sullivan convinced him to surrender, Doc was arrested and sent to Bellevue Hospital Center, where he remained until the end of the show.
