CENTENNIAL, Colo. – The photos were chilling and enigmatic, just like their subject. In the pictures, taken on his iPhone hours before the Aurora movie theater massacre, accused gunman James Holmes mugs for the camera, sticks out his tongue and smiles as he holds a Glock under his face and displays his arsenal arrayed on his bed.

Prosecutors who displayed the pictures at a hearing that ended Wednesday argued the photos display “identity, deliberation and extreme indifference.”

Holmes’ attorneys – who have been setting up an insanity defense and said they might present testimony about the defendant’s mental health – decided not to call any witnesses.
