David Allan Chevrier, a 25-year-old Indigenous man, went missing from North Bay, Ontario, in June 1994. Reports differ on whether he was last seen on June 22 or June 23. At the time he lived in a group home on McIntyre Street West and was last seen leaving, possibly heading toward the Centre of Friends in downtown North Bay.

David lived with schizophrenia and an intellectual disability from a prior car accident, described as having the cognitive function of a young child. He was known to wander, talk to himself and squint. He was about six feet tall, 160 pounds, with a dark complexion, brown eyes and black hair in a crew cut. He was wearing a black t-shirt or sleeveless top and grey track pants when last seen. Searches by the North Bay Police Service, including an Ontario Provincial Police helicopter search of the Lake Nipissing shoreline, turned up no trace. A possible sighting near the government dock was followed up but not confirmed.

The case has remained open; investigators have tried to match him to unidentified remains and renewed appeals for information in 2016 included his sister Pauline, who fears he may have met with foul play and has voiced concern about the case receiving lower priority because he was poor, mentally ill and Indigenous. Anyone with information about David’s disappearance is asked to come forward.
