Laundrie was the subject of an extensive manhunt. Human remains - and Laundrie's property - were found in a Florida park earlier this week, and, after a forensic investigation, and an examination of dental records, the remains were confimed to be those of Laundrie.
This news comes after Petito's cause and manner of death were confirmed to be homicide by strangulation, and brings to a close a case which has become a world-wide phenomenon.
