On July 24, 1993, 37-year-old Lori Ann Duncan was killed in Mason City, Iowa, along with her daughters Kandace, 10, and Amber, 6, and her boyfriend Gregory Nicholson. To prevent that testimony, Honken and his girlfriend Angela Jane Johnson allegedly carried out a planned attack.

Johnson reportedly gained entry to Nicholson’s home posing as a lost saleswoman. Once inside, she and Honken subdued and bound Nicholson and Lori Duncan, then deceived the children with a promise of a surprise trip. The family was forced into a vehicle at gunpoint and driven to a remote wooded area outside Mason City, where all four were executed.

The victims’ remains were not found at the time. If anyone knew Lori, Kandace, Amber, Gregory, or saw anything unusual around Mason City in July 1993, please share what might help clarify those last movements.
