The judge in the Aurora shooting case in CO has entered a "not guilty" plea on gunman James Holmes' behalf.
The plea was entered today by default after Holmes' attorney said he wasn't ready to enter a plea by the judge's deadline.
The judge said Holmes -- who now has long hair and a giant beard -- may change his plea to not guilty by reason of insanity at a later date if he chooses.
Holmes is charged with 142 crimes stemming from the Colorado shooting -- including 24 1st degree murder counts, and 116 counts of attempted murder. If convicted, he faces life in prison ... or execution.
