Burke's Law - Season 2 Episode 14 : Who Killed the Swinger on a Hook? 1966

Someone seems to be systematically killing a group of individuals on a list. One name on the list - Amos Burke. What is the connection between these people? One possible suspect (who's name also appears on the list) is badly beaten, and Burke finally discovers that the solution comes from a case many years ago when he was just starting out on the police force. Can he trap the killer before he becomes the next victim? After one attempt on his life fails, Burke is kidnapped, but leaves his phone line open to the station so that Les and Tim can track where he's being taken. The case ends with a fight in an abandoned mine shaft.
