Story highlights Suspect Steven Jones is charged with first-degree murder, aggravated assault; bail is $2 million

All four shooting victims were members of the Delta Chi fraternity, organization says

(CNN) A freshman accused of shooting four fellow students at Northern Arizona University has been charged with one count of first-degree murder and three counts of felony aggravated assault.

Steven Jones, 18, said "Yes" when a Coconino County judge asked him over a video feed Friday afternoon if he understood the charges. Bail was set at $2 million.
