A photo has been published online of James Holmes, the suspect in the mass shooting at a movie theater in Aurora, Colorado on Friday.
The 24-year-old man is being held in custody for gunning down 12 people in a mass shooting spree during a midnight screening of "The Dark Knight Rises."
In addition to 12 deaths, 50 people have sustained wounds from the gunshots.
Colorado news outlets have revealed an aerial video of police cautiously searching Holmes' apartment just miles from the Century Aurora 16 theater where explosives were located.
Survivors of the shooting said that Holmes appeared in the theater about 20 minutes into the movie with a rifle, handgun, and gas mask. First, he threw a canister which released a gas-like substance, and after shooting at the ceiling, opened fire into the crowded theater audience.
"We were maybe 20 or 30 minutes into the movie and all you hear, first you smell smoke, everybody thought it was fireworks or something like that, and then you just see people dropping and the gunshots are constant," witness Christ Jones said, according to ABC Denver's associate KMGH.
"I heard at least 20 to 30 rounds within that minute or two," he added.
Little is known about the shooter aside from his being a drop-out student at the University of Colorado, Denver. Holmes' parents reportedly live in San Diego, Calif., and have offered their condolences to the families of the victims of the tragic shooting.
There was no immediate word of any motive for the attack. Federal law enforcement officials were briefed on the attack, but at this point there is no indication that it is terrorist-related, according to CBS.
