12 people were killed and at least 50 others were wounded early Friday when a gunman wearing a bulletproof vest opened fire during a midnight premiere screening of the latest Batman movie The Dark Knight Rises near Denver, authorities and witnesses said.
The apartment of the suspect in custody, named as James Holmes, 24, who had been a student at the University of Colorado Medical School, had been booby-trapped with what police described as sophisticated explosives or flammable material, and officers were trying to determine how to defuse the device or devices, Aurora Police Chief Dan Oates said.
The area had been evacuated, and police were expected to remain on the scene “for hours or days,” he said.
Police said there was no evidence of additional suspects.
“We’re pretty confident he acted alone,” Officer Frank Fania told TODAY.
