Rear Window
One example of a forensics scene from the movie rear window is the scene where Jefforys is watching his neighbor the morning after the rainy night. He notices that his wife is no longer in the apartment, but what really gets his attention is when his neighbor takes out a very long saw, and a very long knife out from the sink, wraps them in news paper, and packs them in a suit case. When he does finally get a glimpse of the bed room where his neighbors wife used to reside, the mattress is all rolled up, as if something extremely messy had happened on it, and their is a large crate in the room. This sends Jefforys, who has been locked in his room for 7 weeks with nothing to do, into a fervor. He becomes obsessed with finding out what really happened to his neighbors wife because he has convinced him self that she was murdered.
