Other mistake: When the killer and the girl's body fall out of the window she's barefoot. Given she'd been dug up she should've been wearing shoes.

1 other mistake
Directed by: Herb Freed
Starring: Christopher George, E. Danny Murphy, E.J. Peaker, Patch Mackenzie
Continuity mistake: The actress playing Dolores is suddenly played by scream queen Linnea Quigley. The original was recast due to the actress having problems with the nudity, and shots of her were cut out as much as possible.
Roberts: All right, look. Whoever it is, I know who you are.
