RCMP in Tumbler Ridge, B.C., say they don't know where the primary gun used in a mass school shooting earlier this week came from.
They say the attacker used an unregistered shotgun to kill her mother and sibling at their home before using different firearms at the school.
RCMP Deputy Commissioner Dwayne McDonald says a shotgun was the main firearm used in the mass shooting at the school and it had never been seized by the RCMP.
McDonald says they don't know the origin of the shotgun and police are trying to identify its owner and the source of all four firearms used in both locations.
He says investigators believe the killer was not specifically targeting people, but was instead "for lack of a better term, hunting," victims.
McDonald says the killer was prepared and engaging anybody and everybody she could come in contact with.
