Joseph Edward Duncan’s criminal history began in Tacoma, more than two decades before he was finally incarcerated for good. In 1978, he sexually assaulted a young boy at gunpoint. Duncan was only 15 years old. This would begin a series of violent crimes of a sexual nature, which Duncan seemed to be very proud of. He told a therapist that by the age of 16 he had sexually abused more than a dozen young boys.

In 1980, Duncan was sentenced to 20 years in prison after kidnapping and sexually assaulting a teenager in Tacoma. He had also stolen firearms from nearby homes. Duncan would be released for six years in early 1994. Duncan is believed to have killed three people while still on parole, including two young girls from Seattle. He will return to prison in 1997 to be released again in 2000. They should have kept him behind bars.

When Duncan was released in 2000, he moved to North Dakota. He was in police custody again in 2005, when he was charged with assaulting two boys while in Minnesota. After being released on bail, Duncan left town and a federal warrant was issued. While traveling through Idaho, Duncan spotted two children playing in the yard. He would inspect the house.

Shasta says she and her older brother Dylan were lucky they never saw their family murdered, having been taken away in a red Jeep Cherokee moments before. It was six long weeks on the road with their abuser, as Shasta and Dylan were victims of multiple sexual abuse. Dylan was tragically murdered, having been shot in the stomach and head, although Duncan claims the first shotgun blast was an accident.

Shasta was nearly murdered herself. According to accounts, after killing Dylan, Duncan gave him two choices: death by gunshot or death by strangulation. She begged Duncan, calling him by his nickname until he stopped. He took Shasta back to Cour d’Alene, where she would be rescued and returned to her biological father.
