Joseph Edward Duncan III is an American convicted serial killer/rapist and pedophile.

Background
Duncan was born on February 25, 1963, in Tacoma, Washington, where he was raised. In 1978, at the age of 15, he committed his first known sex crime, raping a nine-year-old boy at gunpoint, which he was arrested for. The following year, he was arrested again for driving a stolen car. Sentenced as a juvenile, he was sent to Dyslin's Boys' ranch, where he was assigned to hold meetings with a therapist. Released after a few months, Duncan stole several guns from a neighbor in 1980, later abducting, raping, and sodomizing a 14-year-old boy at gunpoint, later getting caught and sentenced to 20 years in prison. In 1994, fourteen years after his sentencing, he was paroled under the condition that he would not engage in any interaction with minors. Initially sent to a halfway house, Duncan began living in other locations in the Seattle, Washington area, and eventually violated his parole two years later, being arrested for marijuana usage and firearm possession. He was sent to jail for a full month but was paroled again, with newer restrictions. During his parole, it is believed that he murdered ten-year-old Anthony Michael Martinez of Indio, California, in 1997, as well as his alleged and suspected victims. On March 31, 1997, Duncan violated his parole again by stealing his girlfriend's car and traveled abroad, but was later arrested in Kansas and returned to prison. However, he was again released from prison, on July 14, 2000, for good behavior, and Duncan moved to Fargo, North Dakota. On July 3, 2004, Duncan molested two boys at a Detroit Lakes, Minnesota playground, which he would be arrested for and charged with on March 2005. A Fargo businessman who was an acquaintance of Duncan's helped him post his $15,000 bail, but Duncan skipped bail and went on the run. On June 1, 2005, a federal warrant was issued for Duncan's arrest for not showing up at his trial.

Modus Operandi
According to Shasta Groene, Duncan held the Groene family at gunpoint and used nylon zip-ties to restrain Brenda Groene, Mark McKenzie, and Slade Groene, all of whom he murdered by bludgeoning them to death with a hammer. He also molested Shasta and Dylan Groene, the latter of whom he killed through unspecified means. According to a confession given by Duncan, he molested Anthony Martinez as well and killed him by bludgeoning him with a rock.

On Criminal Minds
Though he wasn't mentioned or referenced in Criminal Minds, Duncan may have been mentioned alongside Thomas Dillon in the Season Eight episode The Apprenticeship. However, the details the BAU provided of the named criminal do not match official details given on Duncan. Additionally, his habit of killing the parents and the oldest child, dumping them together afterwards, and then killing one of the youngest children and dumping him in a separate location seems to be similar to Arthur Rykov's attack on the Yamada family.
