The father of a two-year-old girl who died after she was starved and neglected has pleaded guilty to manslaughter and failing to provide the necessaries of life.

The little girl, known as "M", was taken off life support in September 2012  in a case that went to the Supreme Court of Canada.

He also pleaded guilty to aggravated assault against his other twin daughter, known as “S.”.

Both twins, just over two years old at the time, were removed from the family home in May 2012. Both were found to be severely emaciated and covered in cuts and bruises.

Child “M” had stopped breathing and had no pulse after she received a blow to the head. She died just over two hours after being removed from life support.

Her sister was found to have delayed motor skills and was unable to stand without help, but survived the emotional and physical abuse and was made a ward of the province.

The couple’s four-year-old son was found to be well-fed and had not been physically abused.

The father, who was appeared in the orange coveralls worn by Remand Centre inmates, bowed his head and wept as the agreed statement of facts was read out.

He told the court that he and his wife were the children’s only caretakers. He said he failed his legal duty as a parent when the girls were “too weak to protect themselves from physical abuse.”

The parents, both 35, cannot be named under Alberta law because their two surviving children are wards of the province. The children have now been placed with other caregivers.

The children’s mother is scheduled to appear in court next month. The father will likely face sentencing in May or June.
