A national college fraternity based in Evanston, Ill., is involved in the investigation of a campus shooting in Flagstaff, Arizona.
Sigma Chi Fraternity has confirmed that 18-year-old Steven Jones was seeking membership in the Sigma Chi chapter at Northern Arizona University.
The fraternity’s executive director, Michael Church, also said in a statement that the NAU chapter's operations in Flagstaff have been suspended while the fraternity investigates the shooting.
Jones is accused of killing Colin Brough, of Castle Rock, Colo., and wounding three other students last Friday.
Jones told authorities that one of the victims punched him in the face during a confrontation in a parking lot outside an NAU residence hall. Jones then got a gun from his car, authorities said, and began shooting.
All four victims were members of the Delta Chi Fraternity chapter at NAU. That fraternity, based in Iowa City, Iowa, has said there is no connection between the incident and any fraternity activity.
Jones is being charged with first-degree homicide and three counts of aggravated assault.
Sigma Chi fraternity does not have an active chapter at Northern Illinois University.
