Canadian police identify 18-year-old woman as suspect in mass school shooting

Unlike the United States, school shootings are almost unheard of in Canada, and federal politicians initially struggled to maintain their composure.

The suspect in a deadly school shooting in western Canada was an 18-year-old woman with mental health issues who killed her mother and stepbrother before attacking her former school, police said on Wednesday, but investigators did not offer a motive for one of the worst mass slaughters in Canadian history.
