Centennial, Colorado (CNN) - A student opened fire Friday inside a suburban Denver high school, injuring at least three people before turning the gun on himself, authorities said.
The shooting began after the student entered Arapahoe High School in Centennial with the intention of confronting a teacher, Sheriff Grayson Robinson told reportera. The sheriff declined to identify the dead gunmen.
"I want to again repeat to you the suspect has been found inside the school and he has deceased as a result of what appears to be a self-inflicted gunshot wound," Robinson said.
