CASA GRANDE — A Casa Grande man who was involved in a fatal head-on accident that killed four people near Flagstaff has been sentenced to 24 years in prison.

According to Coconino County Superior Court records, Carlos Quinonez, 21, was convicted by a jury in mid-October of negligent homicide, endangerment, criminal damage and misdemeanor driving under the influence. It is unclear when he was sentenced following his conviction.

He was originally charged with four counts of manslaughter, four counts of endangerment, one count of criminal damage, one count of driving under the influence and one count of driving under the influence with a blood alcohol count of 0.08 percent or higher.

His attorney has filed a motion for a new trial.

According to the Arizona Department of Public Safety, Quinonez was driving a Jeep the wrong way in the northbound lanes of Interstate 17 south of Flagstaff at 4:12 a.m. on Aug. 18, 2017, when he collided with a Nissan. The Nissan was carrying four friends from California who were on their way to the Grand Canyon.

The four occupants of the Nissan were killed in the crash. They were identified as Christen Ebert, 26, Richard Chum, 30, Gary Sindhu, 29, and Kouang Saefong, 30.
