Post Mortem | Cati Blauvelt: Death of a Soldier’s Wife 

48 Hours Correspondent Peter Van Sant and Field Producer Kat Teurfs discuss John Blauvelt, a one-time military recruiter who went on the run with his teenage girlfriend after stabbing his wife, Cati, to death. When U.S. Marshals finally tracked him down six years later, he was using a different name and living with a new girlfriend across the country. They discuss the murder weapon, the pirate tattoo authorities used to identify Blauvelt, and the journal where he wrote "I did it."
