2015 Northern Arizona University shooting

Jones' trial began on April 5, 2017, at the Coconino County Superior Courthouse in Flagstaff, Arizona.[6] Thirty-eight witnessess, all three surviving victims, and Jones himself testified.[7] The jury began deliberation on April 25, though they were unable to reach a verdict,[8] and a mistrial was declared on May 2.[9]

A retrial was originally scheduled for August 1, but five delays postponed it until February 2020.[10] In December 2017, prosecutors agreed to reduce the charge to second-degree murder, in part to avoid double jeopardy.[11] On January 9, 2020, Jones pleaded guilty to one count of manslaughter and three counts of aggravated assault, one month prior to the scheduled retrial. On February 11, he was sentenced to six years in prison. Jones is currently located at the Red Rock Correctional Center in Eloy, Arizona.[12]

Nicholas Acevedo, one of the 38 witnesses in the original trial, died of suicide on March 4, 2018,[13] prior to the retrial's scheduled date.[14] His parents, Steve and Karen Acevedo, believed that the trial had contributed to his suicide.[15]

On June 30, 2017, a civil lawsuit for negligence was filed against Jones and his parents by Piring, Prato, and Brough's parents, Douglas and Claudia Brough.[16] The case was dismissed in January 2018, after the parties reached a confidential settlement.[17]
