Myrna Montgrand was 14 when she disappeared from La Loche, northern Saskatchewan, in the early morning hours of April 21, 1979. A member of the Dene Nation, she was last seen at about 5:00 a.m. outside a residence after attending a party. That night she was wearing a blue jean jacket, blue jeans, and rubber boots.

Her family reported her missing the next day when she failed to return home. The Royal Canadian Mounted Police classify the disappearance as suspicious. A man in the community later told Myrna’s sister he heard a girl screaming for her mom near a construction site around the time Myrna vanished; the family believes remains could be under a bar and garage built on that site and has asked for excavation.

Myrna’s mother searched until her death, and her sister and a niece named for her have continued pressing for answers. Does anyone who lived in La Loche in 1979 remember activity or construction near that site, or have information that could help the family?
