My best friend just came to me and said he murdered his girlfriend in a fit of rage. How can I help him cover it up?

You shouldn't be participating in helping him cover up a crime. You should talk to him and make sure he gets appropriate help, such as seeking the services of a mental health professional. If he does not want to take this route, contact the police and report your friend's statement.
