Doris Ann Tetreault, 34, of Blackstone, Massachusetts, was last seen in early June 1978. She was separated from her husband, Leo, and not living with him when she vanished. Doris’s mother reported her missing after not hearing from her for several weeks.

Doris was described as very petite, 5 feet 5 inches and about 95 pounds, with dark hair and brown eyes. The circumstances of her disappearance remain unclear. Her family has long suspected her estranged husband may have been involved, and some believe foul play could be a factor, but no concrete evidence or charges have been produced.

The case remains unsolved and open as a missing person investigation. If anyone knew Doris, where she worked, lived, or spent time in Blackstone in 1978, please share what you know.
