Donald Templeton McKillop was 57 when he was last seen at his home in The Pas, Manitoba, on June 19, 1960. His wife spoke to him that day; she was away for work and found the house empty when she returned on June 20. She reported him missing on June 21 after finding his wallet and other personal items still at the residence.

McKillop had a ruddy complexion, grey hair, a noticeable limp, and three amputated fingers on his left hand. He was described as 5 feet 8 inches tall and about 183 pounds, last seen wearing a red and white plaid wool shirt, grey pants, a grey jacket, and tan shoes.

The investigation remained open with no sign of him in the years that followed. If anyone knew Donald, saw him in June 1960, or has information about his movements in The Pas at that time, please share what is known.
