A Fort Resolution, N.W.T., man has been charged with manslaughter in the death of Mary Laboucan.
Staff Sgt. Brad Kaeding said RCMP arrested Steven Sayine, 38, Thursday morning. He says Sayine was in a domestic relationship with Laboucan.
"He was known to the investigators from the beginning and once the evidence was at hand sufficiently to determine an offence has been committed, he was arrested," Kaeding said.
Kaeding said an autopsy will be done to determine the cause of Laboucan's death. He said as far as they know, no weapons were involved in her death.
She was treated at the health centre in Fort Resolution for unknown injuries on Saturday and died Tuesday in hospital in Edmonton.
Laboucan's sister Susan Firth said she will remember her kindness and generosity. Once, while visiting in Alberta, Firth said Laboucan took off the jacket she was wearing and gave it a homeless person.
Laboucan was born in Saskatchewan and lived in Alberta but made the Northwest Territories her home.
Firth said Laboucan had lived in the N.W.T. for the past 15 years in Fort Resolution, Hay River and Yellowknife.
She worked for De Beers at the Snap Lake Mine.
There are no plans for a funeral service in the territory. Firth said the family will hold a private memorial in Alberta at a later date.
She said friends who wish to make donations in Laboucan's name are welcome to choose a charity of their choice.
