The Vancouver man accused of murdering eight people by ploughing a vehicle into a crowded street celebration on Saturday night had been grappling for months with the impact of his brother's murder.

VANCOUVER, British Columbia — A 30-year-old man was charged with multiple counts of murder on allegations he killed 11 people when he rammed a crowd of people at a Filipino heritage festival in Vancouver, as hundreds attended vigils across the city for the victims and the Canadian prime minister visited the site on the eve of a federal election.

The incident, which took place at a Filipino street festival, was unlikely to be a terrorist attack, police said. The suspect, a 30-year-old man, was known to police from prior mental health calls.
