On July 20, 2012, a mass shooting occurred inside a Century 16 movie theater in Aurora, Colorado, during a midnight screening of the film The Dark Knight Rises.
A gunman, dressed in tactical clothing, set off tear gas grenades and shot into the audience with multiple firearms.
Twelve people were killed and 70 others were injured, the largest number of casualties in a shooting in the United States until the Orlando nightclub shooting four years later.
This also was the deadliest shooting in Colorado since the Columbine High School massacre in 1999.
The official story is that a local University of Colorado student James Eagan Holmes purchased a ticket to the am showing, sat in the front row of the theater 9 and then about 20 minutes into the movie left through an emergency door to the rear of the theater where his car was parked out back.
He then is said to have donned protective gear and loaded up with weapons, then returned to the theater through the same door ten minutes later at approximately am, tossed a couple of cans of gas into the crowd and began shooting.
Horrific: Seen from the air, blood-stained footprints dot the back of the Century 16 movie theater where suspect James Holmes went on a shooting rampage during on July 21, 2012 in Aurora, Colorado.
Arapahoe County prosecutors sought the death penalty for Holmes. He was convicted of 24 counts of first-degree murder, 140 counts of attempted first-degree murder, and one count of possessing explosives on July 16.Harrowing accounts from survivors dominated the first week of Colorado's movie theater massacre trial, but amid the tears a much more detailed picture emerged of gunman James Holmes, his personal life, and his deadly plan.Prosecutors seeking the death penalty for the 27-year-old former neuroscience graduate student, and his public defenders, have filled in many of the gaps left when a judge sealed much of the key evidence in the 2012 mass shooting case.Mr Oates was clear to mention that while they were still trying to determine the circumstances leading up to the fatal attack - and what, if any, motive the young man had - he said that police are confident in saying that he acted alone.The first time that police began to think that there may have been an accomplice was when a local officer received a threatening electronic message Saturday evening, demanding that Holmes be released from custody or else the sender would become violent.
