Manitoba chief says healing needed after 11-year-old girl's killer sentenced

WINNIPEG — A Manitoba grand chief says a remote northern First Nation is still healing after the gruesome killing of an 11-year-old girl.

A 17-year-old boy — who cannot be named — was sentenced on Monday to 10 years for first-degree murder in the 2015 death of Teresa Robinson.

Grand Chief Sheila North Wilson, who represents northern Manitoba First Nations, says many lives were ruined by the killing on the Garden Hill First Nation about 600 kilometres north of Winnipeg.

Robinson disappeared after a children's birthday party and her remains were found in a wooded area six days later.

North Wilson says her heart goes out to the community which she says is still suffering.

She says the "heinous crime" shows more must be done to fund services for children on reserves.
