Colorado movie theater 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 theater 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.
