Three teen suspects have been charged as adults in the parking lot shooting at Hinkley High School that sent three students to the hospital.

The Arapahoe County District Attorney's Office filed charges Tuesday in connection to the Nov. 19 shooting, according to a DA's news release. All three 16-year-old suspects face multiple felony charges.

Larry Renee Jefferson, Dalen Lenale Brewer and Diego Flores have been charged with four counts of attempted first-degree murder and one count of first-degree assault, second degree-assault, and possession of a weapon on school grounds.

Jefferson faces the felony charge of using a prohibited large-capacity magazine during a crime, the release said. Jefferson and Brewer have status conference hearings scheduled in court on Dec. 15. A status conference hearing is scheduled for Flores on March 7. All three suspects face two crime-of-violence sentence enhancers as part of the charges.

The Hinkley students who were shot are both 17, a male and a female, and an APS Avenues student is a 16-year-old male, according to authorities.

A school security officer returned fire when the shooting started around noon, police said, and applied a tourniquet to one of the wounded students. One of the three was taken by ambulance to a hospital, the other two were "self-transported." The shooting stemmed from a fight in the school's parking lot.
