Canada's worst mass shooting erupted from an argument between the gunman and his girlfriend, who survived the attack, a police official said.
The official confirmed to The Associated Press late Thursday that the weekend shooting rampage in Nova Scotia stemmed from a domestic dispute involving the couple. The official, who spoke on condition of anonymity, said more details would be provided at a news conference Friday.
Police have said 51-year-old Gabriel Wortman acted alone in the shooting spree that killed at least 22 people across northern and central Nova Scotia. There are 16 crime scenes in five different rural communities throughout northern and central Nova Scotia.#####
