Isabelle Brooks, 68, vanished after leaving her Markham, Ontario home on foot the night of March 4, 1972. She shared the house with her husband Aubrey at the southwest corner of Highway 7 and the 10th Concession (now Reesor Road). Her husband said she put on a black or maroon coat and a bandana-style scarf and told him she would be back in about a week.

Isabelle was petite, 4 feet 11 inches and about 115 pounds, with grey hair, hazel eyes, a ruddy complexion, a mole on the top of her head, some gold teeth and prescription glasses. The area around the former house remains rural and overgrown. Investigators later treated the case as a cold case and, because of the unusual circumstances of her departure, consider the possibility of foul play. Her dental records have been checked against unidentified remains from the region with no matches.

Does anyone have memories of that Markham area in 1972 or information about Isabelle Brooks’s movements that night?
