|Kojak: Last Rites for a Dead Priest (1974) [Clyde Brookner]: Shot in the stomach in a shoot-out with a police officer; he dies some time later while hiding out in a condemned building, while Jackie Cooper (disguised as a priest) tries to get Stanley to reveal where the stolen jewels are.
Monk: Mr. Monk Buys a House (2008) [Dr. Charles Kroger]: Dies (off-screen) of a heart attack, some time before the episode begins. (Stanley did not actually appear in this episode, as it was filmed after his real-life death; this episode establishes the character's death. Stanley's last actual appearance on the show was in the previous-season episode Mr. Monk Paints His Masterpiece.) (Thanks to PortsGuy and Neil)
