|Zombie Campout (2002) [Zombie]: Appears as a zombie, having died some time before her first appearance.
Prison-A-Go-Go! (2003) [Boom Boom]: Accidentally run over by a car driven by Rhonda Shear during a prison escape; we only hear the impact as Rhonda wonders what she hit. (Played for comic effect.)
A Four Course Meal (2006) [Victim at the Office Party]: Presumably killed by zombies. (I haven't seen this film, but the IMDB's identification of her role seems to give away her fate.)
