Newly-released images show more than 20 bombs in the booby-trapped apartment of Aurora theater shooter James Holmes, who was sentenced last month to life behind bars.
The 27-year-old used soda bottles and wires to rig his apartment with home-made explosives and incendiaries that had to be made safe by experts with the help of a robot.
Buildings surrounding his suburban Denver apartment had to be evacuated in the hours after the July 21, 2012, shootings in which he opened fire during a midnight screening of Batman film "The Dark Knight Rises," killing 12 people.
Holmes was formally sentenced on Aug. 27 to one life term in jail for each victim, plus 3,318 years for the attempted murder of dozens of others. He was convicted after the trial judge rejected his insanity plea.
