A shooter unleashed horror in a remote town in northeastern British Columbia, Canada, on Tuesday — killing 9 people and wounding 25 others in what’s now the third-deadliest mass shooting in the country’s history.

6 victims were found dead in Tumbler Ridge Secondary School, and another died while being transported to the hospital, the Royal Canadian Mounted Police said in a statement. The shooter was also found deceased from what they believe to be a “self‑inflicted injury.”

Approximately 27 people injured in the shooing, two of whom were airlifted to a hospital with “serious or life‑threatening injuries.”

The deadly attack has shaken the small Canadian town of Tumbler Ridge, which has a population of just 2,400 people. The secondary school hosts about 160 students from Grades 7 to 12, according to its website. The school touts its “tremendous sense of community” and “strong and enduring relationships among staff and students.”
