|Pushed to the Limit (1992) [Fighter]: Back possibly broken by Christl Colven during a death-match. (Because hardly any of the fighters are referred to by name in the movie, it's extremely difficult to identify who played which part. The scene in question shows Christl killing an Asian woman in the ring, but I'm not 100% sure that it's Catherine.)
Cyber Bandits (1995) [Hotel Clerk]: Shot to death (off-camera) by Nils Allen Stewart and another thug after she pulls a shotgun on them in her hotel. We only see the start of the shoot-out, but since the thugs later turn up again without a scratch, we can assume that they won.
