|Stripped to Kill II (Live Girls) (1989) [Something Else]: Throat slit (off-screen) by the killer. As I recall, her body is shown above the skylight of Maria Ford's apartment, then crashing through. (It's been a long time since I've seen this movie.)
Mortal Kombat: Annihilation (1997) [Sheeva]: Crushed to death when an iron cage falls on her. We only see her screaming as the cage falls, and do not see her body afterwards.
Star Trek: Deep Space Nine: Empok Nor (1997) [Stolzoff]: Thrown off of a balcony by a Cardassian soldier. (Thanks to Neil)
John Carpenter's Vampires (1998) [Female Master #6]: Killed (off-screen) during James Woods' final battle with the vampires. We don't see what happens to Marjean specifically, but it's pretty clear that they were all wiped out.
Thursday (1998) [Pregnant Woman]: Shot repeatedly in the chest and stomach by Thomas Jane and Aaron Eckhart after she shoots at them during a drug deal gone bad.
Ghosts of Mars (2001) [Young Woman]: Shot by Natasha Henstridge after Marjean attacks Ice Cube. We only see Natasha firing, not Marjean being hit, but her body is shown lying on the floor afterwards.
Hostage (2005) [Officer Carol Flores]: Shot in the shoulder and back by Ben Foster outside Kevin Pollak's home; she dies after managing to crawl into Bruce Willis' jeep. (Thanks to Tal)
