Centennial (Colorado): A student shot at least one other student at a Colorado high school Friday before he apparently turned the gun on himself, authorities said.
The student was wounded when he confronted the gunman at Arapahoe High School in Centennial, a Denver suburb, said Arapahoe County Sheriff Grayson Robinson.
Officers found another injured student while securing the school, Robinson said.
A student was taken to a hospital in critical condition, said Jason Dunkel, spokesman for Littleton Adventist Hospital.
