John Archibald Mcallister, 57, was last seen leaving his Tofield, Alberta home on May 7, 1973. He was described as slender, six feet tall, about 163 pounds, with short grey hair and a fair complexion. On the day he vanished he wore green pants, a green jacket, a tan hat, and brown boots.

A troubling development came when his truck was found abandoned near the remote Lodgepole, Alberta area, a considerable distance from his residence. The Tofield detachment of the Royal Canadian Mounted Police opened an investigation, but no further leads or trace of McAllister emerged and the file went cold.

The family and community have been left without answers about what happened that spring. If anyone knew John, saw him around Tofield or Lodgepole in May 1973, or has information that might clear up his movements that day, please share what is known.
