Pickle was last seen watching television at her family's residence on the Santiam Pass in Sweet Home, Oregon at 10:00 a.m. on July 10, 1990. She has never been heard from again. Her mother was at work at the time of her disappearance. Pickle's stepfather, John Arthur Ackroyd, is the last person known to have seen her. He said he came home during a break from work and asked Pickle if she wanted to accompany him to his job at the Oregon Highway Patrol. She said no and he left. When he returned to the house, Pickle had vanished.

Foul play is suspected in Pickle's disappearance. Ackroyd is the prime suspect in her case. A photo of him is posted belowt his case summary. He is currently serving five life sentences in prison for the unrelated murder of Kaye Jean Turner, who was abducted and murdered in 1978. Ackroyd found her body eight months later and was under suspicion in her case for many years, but he wasn't convicted in her death until 1994. He is also a suspect in the deaths of two other young women. Ackroyd has not been charged in connection with Pickle's disappearance, but her family believes he murdered her. Her case remains unsolved.
