Konrad C. Murach was 42 when he vanished from Ottawa, Ontario after last being seen by family on December 15, 1983. He is described as a Caucasian male, 5 feet 6 inches tall, about 170 pounds, medium build, light complexion, short curly brown hair, and grey eyes. A distinguishing detail noted was stained teeth.

There was no contact from him after that December day and no confirmed sightings. The initial investigation produced no significant leads and the case went cold; police renewed a public appeal in March 2008 but no breakthrough has been reported. The last confirmed contact in the official record remains the family sighting on December 15, 1983.

If anyone knew Konrad, saw him around Ottawa in December 1983, or has information that could help explain his disappearance, please come forward.
