Mark Wayne Clarke was 34 when he was last seen around noon on January 29, 2013, at the corner of Aberdeen Street and Main Street in Kentville, Nova Scotia. A friend had dropped him there; from that moment he vanished and was reported missing to the Kings District RCMP on February 4, 2013. At disappearance he was described as a white male, five-foot-ten, about 160 pounds, with brown hair, blue eyes, a full goatee and long sideburns. He was wearing a canvas winter coat, jeans, gloves and brown hiking boots.

Investigators carried out ground and aerial searches, took statements and followed numerous tips and possible sightings, but none proved to be valid. Police note he sometimes travelled by foot and could be transient, which has complicated efforts to fix a starting point for searches. The RCMP has kept the investigation open while the family continues to search for answers.

If anyone saw Mark in Kentville or the surrounding area around January 29, 2013, or has information about his movements after he was dropped off at Aberdeen and Main, please contact the Kings District RCMP.
