Original story:

At least five people were killed and two others were injured in school shooting Friday in Saskatchewan, Canadian Prime Minister Justin Trudeau confirmed to the Associated Press. A suspect in the shooting at La Loche School is in custody, according to officials.

Police were called Friday afternoon to the school, which is located in a remote part of the Canadian province. A student told CBC News that he heard several gunshots before escaping the building.

"I ran outside the school," Noel Desjarlais said. "There was lots of screaming. There was about six, seven shots before I got outside. I believe there was more shots by the time I did get out."
