James Holmes Mugshot

James Holmes will stand trial in the Aurora, Colorado movie theater shooting.

A judge ruled there is enough evidence for charges and he will be formally arraigned on the 166 counts of murder, attempted murder and other crimes on Friday morning.

The murder charges are 24 counts of first-degree murder and 140 counts of attempted murder.

All of the charges are from the July 20 shooting rampage at the opening of "The Dark Knight Rises" in Aurora, a suburb of Denver, Colorado.

The Associated Press reports the defense in the case is not ready to enter a plea.

According to the wire service, "defense attorneys filed papers Thursday afternoon saying he's not ready to enter a plea," and added the lawyers "are likely to appear in court Friday to ask for the arraignment to be delayed."
