Thomas William Buck was 63 when he left his St. Catharines home at about 9:00 a.m. on May 30, 1993, and never returned. His vehicle was later found abandoned in a parking lot in Niagara Falls, Ontario, and that abandoned car is the chief physical clue in the case.

The record does not identify the parking lot, say how long the vehicle had been there, describe anyone seeing Buck arrive or leave the car, or offer a confirmed sighting of him after he left home. He was described as about 5 feet 11 inches, 181 pounds, with grey hair, blue eyes, a distinctive deformity of his nose, a vasectomy scar, and wearing a gold ring.

His disappearance is recorded under RCMP case number 2014004044 and Niagara Regional Police Service reference 1993-57623. No publicly detailed explanation for what happened to him has been released. Did anyone in St. Catharines or Niagara Falls in 1993 see Buck or his vehicle that morning?
