The remote town of Tumbler Ridge, British Columbia, is reeling after 18-year-old Jesse Van Rootselaar carried out one of the deadliest mass shootings in Canadian history. The rampage began at a private residence where the suspect killed her own mother and 11-year-old step-brother before moving to the local high school and opening fire in the library. Nine people are dead, including five students and a teacher, leaving a small community to grapple with the horror of a tragedy that investigators say involved a suspect with a history of mental health concerns.
