(Centennial, CO)  --  Accused Colorado theater shooter James Holmes will plead not guilty by reason of insanity.  He's charged with killing a dozen people and wounding dozens more during a midnight showing of the latest Batman film last summer. 

A Denver-area judge entered his not guilty plea on his behalf in March just weeks ahead of a report which said his attorneys would agree to a guilty plea to avoid the death penalty.  Prosecutors declined to pursue the offer.
