(KGTV) - A judge has ruled a mistrial in the case of a former Northern Arizona University student accused of killing a classmate in 2015.
Jurors Tuesday were not able to reach an agreement on charges against Steven Jones, 20, including murder, manslaughter, and negligent homicide, according to our ABC-affiliate in Phoenix.
Jones was charged with killing Colin Brough and aggravated assault in the wounding of students Kyle Zientek, Nicholas Piring, and San Diego-native Nicholas Prato following the late-night brawl on Oct. 9, 2015.
The shooting occurred following an argument as students left a party near campus. The fight ended when Jones reportedly retrieved a gun from his car and fired on the group.
Jones claimed self-defense, while prosecutors argued otherwise.
