Oliver Leo Green, 51, vanished after leaving his Oklahoma City home on April 8, 1982. He told his wife he had forgotten something at his office, Torque Master, and drove off; that was the last time she saw him. His company truck was later found unlocked in the parking lot near Wilshire Boulevard and North Rockwell Avenue, which was out of character since he normally locked the vehicle to protect his tools.

Three days after his disappearance an anonymous caller demanded a $300,000 ransom for his safe return; that demand was never followed up and no money changed hands. Mr. Green was described at the time as 5 feet 8 inches, 160 pounds, with blue eyes, greying brown crewcut hair, a scar on his left bicep, a scar on his left wrist, and a tattoo of the initials L.G. on his right upper arm. He was last seen wearing a grey Stetson hat, gold-rimmed glasses, a yellow and brown plaid western-style shirt or a heavy blue shirt, blue jeans, brown cowboy boots, and a belt buckle inscribed T.M.

The case remains open and unresolved, leaving his family without answers about what happened after he left home that April day. If anyone knew Oliver, his routines, his workplace, or has information about the parking lot near Wilshire and North Rockwell in April 1982, please come forward with what was remembered.
