|Deadtime Stories (Freaky Fairytales) (1986) [Magoga]: Heart torn out by Scott Valentine while she's trying to strangle him. After the story ends, we see an "alternate ending" in which she comes back to life and kills both Scott and Kathy Fleig, after Brian DePersia complains about the "happy ending" and Michael Mesmer changes the story. (Lisa's face was covered with ugly "witch" make-up for this role.)
White Hot (Crack in the Mirror) (1989) [Carlos' Girl]: Neck snapped by a thug in an alley, after his partner shoots Michael Marisa Ornstein.
(Note: As a professional stunt performer, Lisa has probably "died" in place of other actresses, though I don't know any specific examples.)
