Bonnie Joan Thomas, 30, disappeared after leaving a St. Patrick’s Day dance on the evening of Friday, March 17, 1978. She had driven from Rollingdam, just outside St. Stephen, New Brunswick, to the American Legion Hall in Calais, Maine, and was returning alone in her red 1973 Volvo station wagon. At the Canadian border crossing her car struck the customs booth and sustained minor damage; the last official sighting places her speaking with a Customs Officer at that point.

Her husband reported her missing the morning of March 18, and later that day her red Volvo was found abandoned on a remote logging road near the St. Croix River. The vehicle’s purse was missing. Thomas was described as 5 feet tall, 185 pounds, with long black hair, brown eyes, a scar on her forehead, visible tooth decay, and wearing faded denim pants and brown leather shoes.

Decades of inquiries have not produced definitive answers, and no suspects have been publicly named. Does anyone have information about Bonnie’s movements that night or recall seeing her car after she left the border crossing?
