Lawrence Thomas "L.T." Horn (1939 – February 2017) was an American musician, record producer and chief recording engineer for Motown Records in Detroit and Los Angeles. He later served a life sentence for hiring a hit man to murder his ex-wife, Mildred Horn, their disabled son Trevor, and nurse Janice Saunders. The case quickly gained national interest, and went on to prompt a lawsuit with Paladin Press, the publishers of a book, Hit Man: A Technical Manual for Independent Contractors, which had been used as a how-to manual by the killer.
