Joseph Edward Duncan III (February 25, 1963 – March 28, 2021) was an American convicted serial killer and child molester who was on death row in federal prison in conjunction with the 2005 kidnappings and murders of members of the Groene family of Coeur d'Alene, Idaho. He was also serving 11 consecutive sentences of life without parole in conjunction with the same crimes as well as the 1997 murder of Anthony Martinez of Beaumont, California. Additionally, Duncan confessed to — but had not been charged with — the 1996 murder of two girls, Sammiejo White and Carmen Cubias, in Seattle. At the time of the attack on the Groene family, Duncan was on the run from a child molestation charge in Minnesota. He spotted Shasta and Dylan Groene playing outside as he drove past their house on Interstate 90.
