Steven Jones has been sentenced to six years in prison after he pleaded guilty to manslaughter and three counts of aggravated assault in a 2015 deadly shooting in Flagstaff.
As part of the agreement, Jones must serve at least 85 percent of the sentencing before being considered for release.
Steven Jones, a Northern Arizona University student at the time, opened fire on a group of people in 2015 after he says he was attacked over a small prank between two rival fraternities.
The fight started after Jones and two pledges from his fraternity carried out a prank by ringing the doorbell of an apartment and running away. The prank set off a fight between Jones and students in the apartment from a rival fraternity. Jones got punched in the face during the altercation.
Jones had said he went back toward the group and fired his gun, but he didn't mean to hurt anyone. He testified he fired several shots "to stop the immediate threat that was coming at me."
Jones admitted to shooting and killing Colin Brough and wounding three other students but told police he did it out of self-defense. The prosecutors, however, said that Jones could have left the area and did not need to resort to using a weapon.
Jones will receive credit for the 212 days he has already been in custody.
