CSI: Miami Season 7 Episode 12

A man, wanders through Miami covered in blood but claiming total amnesia, except that he had killed someone. The blood is from insider trading-accused Mitch Crawford, his wife and their daughter, who were seen leaving by car early that day by courier Walter Leeson, who 'borrowed' their luxury pool. The amnesiac's only memories allow Eric to guess the triple knife murder site. His bloody wallet identifies Doug Benson, whose hammer on site wasn't the murder weapon. Using victim shots as a memory stimulus links with Doug's youth trauma. Horatio finds and links two other suspects.
