CENTENNIAL, Colo. - Colorado movie theatre shooting suspect James Holmes faces arraignment Friday.
That comes after a judge on Thursday night ruled he should stand trial on all 166 counts against him.
But his attorneys say they're not ready to enter a plea.
District Judge William Sylvester ruled that prosecutors had presented sufficient evidence to proceed with charges alleging Holmes killed 12 people and injured 70 others at a suburban Denver movie theatre July 20.
Holmes is charged with multiple counts of first-degree murder and attempted murder.
If convicted of first-degree murder, he could face the death penalty.
