It was this Idaho city near the Washington border that was the last known location of Patricia Otto, according to details shared by Season of Justice. "Patty" was 24-years-old, married, and had two daughters at the time she voluntarily left her home after a reported argument with her husband.

Human remains were discovered in Oregon not far from where Patricia lived years ago, but following testing, no definitive identification was made due to the condition of the remains, which were believed to be similar to those of a woman that may have matched the missing mother's physical characteristics.
