Three cases are highlighted from "The First 48" archive that feature stories of friendship gone wrong: in New Orleans close friends fight over money and one of them ends up dead; in Broward County, Florida, an elderly man makes a fatal mistake with some new friends; and in Dallas, childhood friends have a wild night that ends in tragedy.

In Memphis, Tenn., a man is killed when he tries to break up a fight; in Miami, a well-intended kid is shot at a nightclub; in Tulsa, Okla., a young woman loses her life for something she had nothing to do with.
