Schools across the area in Colorado near Arapahoe High School were put on lockdown following a shooting on Friday.
The shooting left two students injured. The gunman killed himself, the Arapahoe County Sheriff said.
Schools in Littleton, Elizabeth, and Aurora were placed on lockdown, reported ABC.
Cherry Creek schools had outer doors locked, while Douglas County schools were put on lockout, which means all doors were locked.
All the schools are expected to release students soon since the suspected gunman is dead.
