A Colorado jury agreed to consider capital punishment today (August 3) as Holmes's murder trial moves into its final penalty phase.
In July, Holmes was convicted of 24 counts of first-degree murder, 140 counts of attempted first-degree murder, and one count of possessing explosives.
His legal team and family had argued that he was not guilty by reason of insanity prior to the verdict being rendered on July 16.
Holmes killed 12 and injured 70 others when he opened fire at a late-night screening of The Dark Knight Rises on July 20, 2012.
If sentenced to the death penalty, Holmes's execution will make him the first person put to death in the state of Colorado since the 1997 lethal injection of convicted murderer and rapist Gary Lee Davis.
