Bob Crane from Hogan’s Heros also.
Way to weird.
From Wiki:
On a late night in 1978, Crane allegedly called Carpenter to tell him that their friendship was over. The following day, Crane was discovered bludgeoned to death with a weapon that was never found (but was believed to be a camera tripod) at the Winfield Place Apartments in Scottsdale, Arizona.
Bob Crane was "beaten" to death, by someone else.
