Daniel Rene Dumigan was 28 when he vanished from Edmonton, Alberta, in the summer of 1975. The last contact with his family was in July of that year. He was described as five feet nine inches tall, about 150 pounds, with black hair and brown eyes. Specifics about his last known whereabouts and what he was wearing are undocumented.

A tip passed to the family suggested he planned to leave for Vancouver, British Columbia, but there is no record of his arrival or any confirmed sightings there. The case is filed with the Edmonton Police Service under file number 76-13568 and remains open. Little else is known about his final movements, leaving family and investigators with unanswered questions.

If anyone knew Daniel, saw him in Alberta or British Columbia in 1975, or has information that could help, please come forward.
