James Holmes was given 12 life sentences plus 3,318 additional years for the crimes he committed at an Aurora, Colorado movie theater and the bombs in his home on July 20, 2012. Today, Colorado’s District Attorney Office released never-before-seen photos from that tragic day, and each one gives us a closer look into the troubled and twisted mind of the red-headed serial killer.

From boxes of ammunition to full body armor, James Holmes premeditated the entire tragedy, smiling with black contacts on in several photos. Some pictures show his house overfilled with bombs, while more morbid photos show blood stains from the crime scene.

Be advised, all of the photos are extremely graphic. Take a look at them all above.
