James Holmes, who was accused of fatally shooting 12 people and injuring 70 others at a theater in Aurora, Colorado three years ago, has been found guilty of all 165 charges, including 24 counts of murder the first degree.

“This has been an emotional and difficult time for the victims, their families, loved ones and friends,” Colorado Governor John Hickenlooper in a statement. “My hope is that this step brings some peace to each of them, and begins the healing process for all of Colorado.”

After less than 13 hours of deliberation, a jury rejected Holmes’ insanity defense for every one of the charges against him, which also included 140 counts of attempted murder and one count of possessing an explosive device.

During the trial, two prosecution psychiatrists testified that Holmes was legally sane when he carried out the attack while two defense psychiatrists contested that assessment, arguing Holmes suffered from schizophrenic delusions and was not culpable for the crimes.

In Colorado, all of Holmes’ murder charges carry the possibility of the death penalty, a punishment the prosecution has previously pushed for.

According to KUSA, the trial’s sentencing phase will begin next Wednesday and is expected to last about a month.
