Kathryn-Mary Herbert, age 11, was abducted on September 24th 1975, in Abbotsford, British Columbia and likely murdered the same day. She was on her way home from a friend’s place on a school night, and last seen at the intersection of Townline Road and Marshall Road close to the Abbotsford airport around 9 pm. Her body was found almost two months later on November 17, 1975 under some rotting boards from a collapsed outhouse on the Matsqui Indian Reserve north of Abbotsford. Kathryn-Mary’s case has been linked by police to two other murders, that of Theresa Hildebrandt, age 15, also killed in the Abbotsford area (1976) and Monica Jack, age 12, killed near Nicola Lake, BC (1978). Kathryn-Mary’s mother Shari has always believed the case could be solved and together with filmmaker David Ridgen, she undertakes some surprising investigation of her own.
