In the early morning hours of November 15, 1986, a devastating house fire tore through a rural property in Humboldt County, California. Inside the home were 16-year-old twins Jill Hansen and Julie Hansen, their parents Hans Hansen and Betty Hansen, and Hans’s 21-year-old stepson, Donny Hansen.
By the end of the investigation, two teenage girls were dead, one from the fire and one after weeks of hospitalization, and authorities determined this was no accident.
What first appeared to be a tragic fire quickly escalated into a homicide investigation when investigators discovered: evidence of an accelerant used inside the home, multiple spent 12-gauge shotgun shells at the scene, a shotgun hidden on the property that matched those shells, and gasoline purchased days earlier and stored in cans found near the fire’s origin As detectives pieced together the timeline, their focus narrowed to someone inside the house that night. Suspicion centered on Donny Hansen, who had recently returned to the property, purchased ammunition, filled a gasoline can, and later admitted to hiding the shotgun during the aftermath of the fire.
The case became one of the most closely watched trials in Northern California. Donny Hansen was charged with arson, the murder of Jill Hansen, and the attempted murder of Julie Hansen. After nearly 18 months in jail and a high-profile trial that was moved out of Humboldt County, a jury returned a shocking verdict: Not guilty.
In this episode, Ashley Flowers and Brit Prawat look at the case through court records, interviews with investigators, defense attorneys, and Donny’s surviving family, including his stepfather Hans Hansen, who still believes the truth has never fully come out.
Nearly 40 years later, Jill and Julie Hansen’s deaths remain officially unsolved. If you know anything about the deaths of Jill and Julie Hansen, please reach out to the Humboldt County Sheriff’s Department at (707) 268-2539 or fill out their online tip form on their website.
