A teen mother and her mother face charges of criminal negligence causing death after a dog mauled and killed a newborn girl on Montreal's south shore on Monday.
The pair was arrested after emergency workers were called to a house in Saint-Barnabé-Sud, near St-Hyacinthe, on Monday afternoon.
Paramedics found the baby girl covered in deep bite marks and scratches. Police said she had been left strapped in her car seat on the second floor of the house when she was attacked.
There was sufficient evidence to arrest both the mother and grandmother, said Quebec police Sgt. Ronald McInnis. Both had left the infant inside to go look at the yard and neither took "care of the baby," he said.
Two Husky dogs live on the property and were roaming freely when the mauling happened, McInnis added.
Both women will appear in court on Tuesday to face charges of criminal negligence causing death.
