TORONTO (AP) — A Canadian police official says the country’s worst mass shooting erupted from an argument between the gunman and his girlfriend, who survived the attack. The official confirmed to The Associated Press late Thursday that the weekend rampage stemmed from a domestic dispute involving the couple. The official said more details will be provided at a new conference Friday. The suspect was shot to death Sunday morning, about 13 hours after the attacks began. Police have identified him as 51-year-old Gabriel Wortman. They say he acted alone.
