William O'Connell

Television Deaths[]

The Outer Limits: The Chameleon (1964) [The Creature]: Playing one of two aliens, he is presumably killed with a laser weapon by Robert Duvall (who had been transformed into an alien himself). Since one of the aliens survives, and since both William and the other actor were wearing heavy alien makeup, it is unclear whether or not it was William who was killed.
Star Trek: Journey to Babel (1967) [Thelev]: Commits suicide by taking a poison pill, in order to avoid being taken prisoner. He dies while being escorted off the Enterprise bridge (when he discovers said toxin is a lot more fast acting).
Mannix: Licence to Kill - Limit Three People (1968) [John Burke]: Shot to death (off-screen) by Wright King. We learn of his death when Mike Connors informs Karen Black.
