An eighteen year old student walked into the school, carrying a shotgun, and began asking for the whereabouts of one of the school's staff members.
Word quickly reached the staff member and, following active shooter protocols, he left the building.
When the student realized his target was gone he fired two or three shots, from the shotgun, seriously wounding a seventeen year old student.
Police arrived within minutes and as they closed in the shooter took his own life.
Officers found his body as well as two Molotov cocktails, one of which had been detonated, causing smoke issues for the first responders.
At this time it has not been confirmed what the student's motive was in wanting to kill the staff member, or why he shot the female student.
The wounded seventeen year old student was taken to Littleton Adventist Hospital, where she underwent surgery, and is in critical condition.
