Eighteen-year-old Terry Anthony Zubko vanished from the grounds of North Bay Psychiatric Hospital in North Bay, Ontario, in the summer of 1982. On the morning of July 21 he was given a supervised one-hour walk on hospital grounds but did not return; staff searched the immediate area and a nearby highway and later reported him missing to police that afternoon.

Terry was described as a Caucasian male, 5 feet 8 inches to 5 feet 9 inches, about 125 pounds, with straight long brown hair and hazel eyes. Clothing reports vary but may have included blue jeans, a blue shirt, a brown and beige striped v-neck sweater and blue running shoes, or brown cords and an off-white long-sleeved pullover with a black stripe on the collar. He had a slight scar on his upper left nostril and a 12-inch scar on his inner arm.

Family members from Sault Ste. Marie recall Terry as kind and fond of animals, sports, stamp collecting, biking and fishing. They say he feared hospitals and question how he was able to walk away from the facility without money or identification just weeks before a transfer to a higher-security unit. Police searched the hospital grounds and surrounding bush and followed up on reported sightings, but Terry has not been found. Anyone who knew Terry or has information about his disappearance is asked to come forward.
