Joseph Edward Duncan III

Joseph Edward Duncan III (February 25, 1963 – March 28, 2021) was an American convicted serial killer and child molester who is known for his 2005 kidnappings of two children from Coeur d'Alene, Idaho, following the murders of their family members. Duncan's crimes spanned decades and he was convicted of multiple offenses, including the 1997 murder of a 10-year-old boy in Beaumont, California. His life and crimes have been the subject of extensive media coverage and have sparked discussions on the death penalty in the United States, child safety, and the management of sex offenders in the community.

Early Life

Joseph Edward Duncan III was born in Tacoma, Washington. From an early age, Duncan exhibited violent tendencies and was diagnosed with antisocial personality disorder. His criminal activities began in his adolescence, leading to his first arrest at the age of 15 for raping a younger boy at gunpoint.

Crimes

In 1997, he was convicted of the rape and murder of a young boy in California, a crime for which he received a life sentence. However, Duncan's most notorious crimes occurred in 2005, when he murdered Brenda Groene, her boyfriend Mark McKenzie, and her son Slade Groene in their home in Coeur d'Alene, Idaho. Following these murders, Duncan kidnapped the two youngest children of the family, Dylan and Shasta Groene. He held them captive at a remote campsite in Montana, where he continued to abuse them until Shasta was rescued and Duncan was arrested at a Denny's restaurant in Coeur d'Alene.

Trial and Conviction

Duncan was charged with multiple state and federal offenses, including kidnapping, child molestation, and murder. He initially pleaded guilty to the murders in Idaho in exchange for the death penalty being taken off the table for the state charges. However, he was later sentenced to death for the federal charges related to the kidnappings and murders. Duncan's trial and subsequent appeals received widespread media attention, highlighting the brutality of his crimes and the legal complexities of prosecuting serial crimes across state lines.
