Colorado theater shooter James Holmes has been found guilty of murder in the first degree.
Confessed gunman James Holmes faces the death penalty for the violent midnight attack at a Colorado movie theater in 2012.
Holmes, 24, has confessed to walking into the Century 16 movie theater in Aurora, Colorado, on July 20, 2012, wearing protective gear and armed with an assault weapon, other guns and gas canisters.
The theater he entered was showing “The Dark Knight Rises.” Holmes told the crowd he was the Joker before opening fire, killing 12 dead and wounding 70.
His defense team tried to convince jurors that Holmes was insane at the time of the attacks, but the jury did not agree.
Holmes was charged with 24 counts of first-degree murder (2 counts for each victim) and 116 counts of attempted first-degree murder, along with weapons charges.
Judge Carlos A. Samour Jr. has overseen the lengthy trial, which has included almost three months of testimony from over 250 witnesses and 22 hours of videotaped interviews of Holmes, according to The Associated Press.
Prosecutors provided evidence of the detailed planning that Holmes made to carry out the attack, including the booby traps Holmes set up in his apartment to divert law enforcement from assisting at the theater.
Defense attorneys brought in high-profile mental health experts who have diagnosed Holmes with a variety of illnesses, including schizophrenia, and have declared him legally insane.
Holmes will be sentenced either to death or life in prison without the possibility of parole.
