On the Crime And Investigation Network (used to be on A&E), there is this show called "The Rookies". It follows rookie police officers from the time the graduate the police academy, and their first few weeks on the job with their FTO until they get cut loose to patrol on their own.
This episode followed Officer Josh Norris, of the Jefferson County Sherriffs Office in Louisianna. He was 22 years old, and had struggled with his FTO, Officer Danny Bostic who was not impressed at first with Josh. He seemed at the end to improve on all the issues and earn the respect of his FTO, and was cut loose on his own to patrol. At the end of the episode, the screen gave a little background on Officer Josh Norris, including that he proposed to his high school sweetheart on July 4th.
After that, his FTO comes on, looking visibly shaken. While responding to a domestic disturbance call a few weeks after being cut loose on the night shift, Josh was fatally shot when a perp opened fire on him upon arrival at the scene. His backup was his FTO, Officer Bostic, who found Josh face down in a pool of blood and unconcious. He stated he heard the shot and then dead silence. It was said that one bullet killed Josh. It was the first time in 11 years a Deputy in Jefferson Parish had died in the line of duty.
Quite a shocking and sad end to that espisode that showed a promising young man who would have grown to become a great police officer.
