Carl Charles Raun was 31 when he vanished from Red Deer, Alberta, in the summer of 1975. He was reported missing on July 28, 1975, and was never heard from again. At the time he was described as a Caucasian male, 5 feet 8 inches, about 163 pounds, with brown hair and blue-grey eyes.

A fused spine required Raun to wear a brace, and he had a four-inch scar on his back just above his buttocks from prior surgery. Few details about the day he disappeared, his clothing, or possessions have been made public. Authorities have said they suspect foul play, but that has not been confirmed. The Red Deer City RCMP continue to list him as a missing person, and the case remains unsolved.

If anyone knew Carl, his movements in Red Deer in 1975, or has information that could help his family find answers, please come forward.
