At least 12 people are reported dead and 50 others are wounded in a shooting that broke out during a midnight showing Thursday of "The Dark Knight Rises" in suburban Denver, according to media reports.
Suspect James Holmes, 24, is in custody, according to Aurora, Colo., police.
Witnesses at the Century 16 movie theater said the gunman, wearing military-type fatigues and gas mask, set off a smoke bomb and then made his way through the theater, gunning people down.
Bullets went through the theater wall, injuring people in the screening next door, as well.
The Huffington Post reported that some 250 police officers responded to the scene and found the suspect near a car at the back of the theater. He was carrying a knife, handgun and rifle and wearing a bulletproof vest.
Police originally announced that 14 people had died in the attack, but revised the death toll around 7:45 a.m., NBC News reported.
The latest in the "Batman" movie series premiered Thursday nationwide, including Gwinnett County.
"Our hearts and prayers go out to all the victims and their familes in this senseless tragedy," he said. "I don't think any of us can understand what drives a person to do such evil. Things like this can drive us to fear and despair, but I hope they drive us instead to faith and courage. It is the Lord's help me need more than any in this nation. Evil will not triumph where faith is strong."
AMC, the second-largest movie theater chain in the country, with a nearby location at Discover Mills, said this in an email statement:
