A school shooting in the western Canadian province of Saskatchewan on Friday left four dead and others wounded, according to the the Royal Canadian Mounted Police.

The shooting occurred at the 900-student La Loche Community School, which teaches students from kindergarten through high school, around lunch time. The shooter, whom The New York Times is reporting to be an unidentified male, now taken into police custody.

The shooter also reportedly chatted a friend about his intentions just before he went to the school with a gun. From the Canadian Press:

Desjarlais-Thomas forwarded to The Canadian Press a screenshot of a chilling exchange that had taken place on social media a short time before the shooting between a young male and his friends.

“Just killed 2 ppl,” wrote the young male. “Bout to shoot ip the school.”

“Why?” asked a friend. “Why?”
