Patricia Lynn Swanberg, 34, vanished from Corvallis, Oregon in the late summer of 1992. The last confirmed sighting was August 10, when a colleague saw her leave work to use a pay phone. Two days later her employer reported her missing after she failed to show for a shift.

Police found her car abandoned and unlocked in downtown Corvallis the day she was reported missing; her purse and personal items were inside. Her apartment was also searched and all clothing and possessions remained, suggesting she did not plan to leave. Family members say she had been in an abusive relationship and had sought a restraining order; her ex-husband was questioned and denied seeing her after the day before she disappeared.

The Corvallis Police Department keeps the investigation active. The family believes she is no longer alive, and officers identified a major person of interest who has since died. Does anyone who knew Patricia or lived in Corvallis in 1992 have information that could help explain what happened?
