The RCMP plans to apologize to Amber Tuccaro's family this week, nine years after her disappearance.
An independent federal review of the Leduc RCMP's investigation into the 20-year-old Mikisew Cree Nation woman's disappearance found that police work in the case was "deficient."
Amber Tuccaro was last seen in Nisku on Aug. 18, 2010, a day after flying into Edmonton from Fort McMurray with her infant son.
Her remains were found on a farmer's field in rural Leduc County two years later. Her murder remains unsolved.
