Police Radio Transmissions Raise The Possibility There Were Multiple Shooters In The 'Dark Knight' Massacre (Business Insider)
At a July 20 press conference Aurora police Chief Dan Oates said investigators were confident that James Holmes acted alone in the largest mass shooting in U.S. history by casualties and that authorities were "not looking for any other suspects."

But doubters are citing official evidence to question that Holmes was the only shooter, or a shooter at all.

The argument of the skeptics can be split into three categories: the discovery of Holmes, the real-time testimony on police radio transmissions and the extra evidence at the scene.
