a.k.a. Monique Gata Dupree, a.k.a. Tha Original Gata
|Skeleton Key 2: 667, Neighbor of the Beast (2008) [Posh]: Drowned when an unseen creature pulls her under in the swimming pool. (Note: She returned in the 2011 sequel Skeleton Key 3: The Organ Trail; since I haven't seen that, I don't know whether it's revealed that she survived this, or whether she returns as a ghost or zombie.)
Bikini Bloodbath Christmas (2009) [Dungaree]: Throat torn out by Matt Ford in the restroom.
Cottonmouth (2009) [The Bloated Ghost]: Dies (off-screen) of toxic shock syndrome, some time before the story begins; she appears as one of a group of ghosts who return to get revenge on John Brodie. (I haven't seen this short film, but I have read the original story on which it was based.)
The Lovecraft Chronicles: Dumas (2010) [Vampire Bride]: I don't know the circumstances of her death (though I'm assuming a stake through the heart), but her IMDB page includes a promotional photo of her death scene.
