There was this movie I saw a long time ago (mid nineties) and here is how the story goes... These two guys (one was a bigger black man) break into a really nice house to steal stuff and they find the man whom, they think, lives there. This guy pretends to be the owner of the house (a wealthy doctor I think) but later in the movie we find out that the little white guy who appears to be the owner, was actually a murderer who broke into the house and killed the residents. There is also a latino girl in the movie who plays the black guys girlfriend, and she ends up running off with the murderer guy midway in the movie. This one may be tough.
