Karl Heinz Behr was 27 when he was last seen after leaving a family gathering in Edmonton, Alberta, on December 25, 1981. He left the event intending to return to his residence but never arrived. His green parka and winter boots were missing from his home, suggesting he may have been wearing them when he disappeared.

Karl is described as a Caucasian male, 6 feet 2 inches tall, about 176 pounds, with blonde hair, blue eyes and a slight German accent. There were no signs of struggle or forced entry at his home, and no witnesses have come forward about his movements after he left the family function.

The case remains an open investigation with the Edmonton Police Service and the family continues to seek answers about what happened that Christmas night. If anyone remembers seeing Karl, his parka or boots, or has information about his movements on December 25, 1981, please come forward.
