Robert Plumb, known as Bob, was 55 when he vanished from Clackamas County, Oregon. He was last seen on June 3, 1984. At the time he was described as a white male, five feet, seven inches tall, about 160 pounds, with blue eyes and gray or partly gray hair.

Very little else is publicly known about his disappearance. No specific location within Clackamas County, no account of his last activities, clothing, or whether he had access to a vehicle has been reported. The case is handled by the Clackamas County Sheriff’s Office and remains listed among Oregon’s missing persons.

If anyone knew Robert Plumb, where he worked, lived, or might have been in early June 1984, can you share what you remember with investigators?
