|Deadly Games (The Eliminator; Who Fell Asleep) (1982) [Chris Howlett]: Buried alive by Steve Railsback. She passes out from fright after he chases her through the woods, then regains consciousness beside a makeshift grave; she then falls in, and the scene fades out as Steve starts throwing dirt into the grave.
Loving (1995; I don't know the exact date) [Gwyneth Alden]: Reportedly commits suicide with a poisoned needle. (I haven't seen this episode myself.) (Thanks to Richard)
