|Terror Firmer (1999) [Pregnant Woman (Death by De-Fetustration)]: Dies of shock/blood loss after Sheri Wenden performs a "manual caesarean-section" while Oakley is lounging on a rooftop. (The scene ends with Oakley still alive and screaming, but a newspaper headline and the closing credits establish that she dies.)
The Dead Hate the Living! (2000) [Zombie Corps]: Plays a zombie (though I don't know whether or not she "dies" a second time).
The Gravedancers (2006) [Haunted Woman]: Hanged after a ghost pushes her off of a balcony. (Thanks to Lauren)
