A 17-year-old boy was charged with four counts of first-degree murder and seven counts of attempted murder in a mass shooting at a school and home in a remote aboriginal community in western Canada, officials said. Police said the male suspect can't be named under Canada's Youth Criminal Justice Act. Royal Canadian Mounted Police Supt. Grant St. Germaine said nine people were shot in the school, including a female teacher's aide who died at the scene and a male teacher who died in a hospital. He said seven people wounded in Friday's shooting at the school are hospitalized, AP reported. Two brothers, 17-year-old Dayne Fountaine and 13-year-old Drayden, were shot and killed in a home before the gunman headed to the grade 7-12 La Loche Community School, police said. Police responded to a call of shots fired at the school shortly after the lunch hour. Royal Canadian Mounted Police Commanding Officer Brenda Butterworth-Carr said when officers arrived at the school they saw the front door had been shot open. They entered the school, spotted the suspect and gave chase before apprehending him. He is due in court next week. Police said Saturday that they were not aware of a motive and declined to say what type of gun was used.
