Hours after the shooting, a bomb robot was deployed to search James Holmes car, a white Hyundai Coupe that was parked at the rear of the cinema complex.
However, no bombs were found inside the vehicle.
Dozens of police were at the scene, and the authorities evacuated the area while they checked for any explosive devices.
The police chief said the suspect told investigators he had multiple explosives at his residence in a North Aurora apartment building, and investigators later found the apartment booby-trapped with flammable and explosive materials. Residents at five nearby buildings were ordered out of their residences as authorities sought to disarm the dangerous site.
Chandler Brannon, 25, who had been watching the movie with his girlfriend, said that about 20 minutes into the movie he saw a smoke bomb go off and heard what sounded like fireworks. He later realized they were a rapid volley of gunshots.
“I told my girlfriend to just play dead,” he told Reuters, adding that he never got a full view of the gunman. “All I could see was a silhouette.”
When the gas began to spread, some moviegoers thought it was a stunt that was part of the “The Dark Knight Rises,” one of the most highly anticipated films of the summer.
The suspect was taken into custody and identified by federal law enforcement officials as 24-year-old James Holmes. The officials spoke on condition of anonymity to discuss an ongoing investigation.
James Eagan Holmes, 24, maniacally laughed at cops like Batman’s archenemy and declared, “I am the Joker” after he was arrested outside the Century 16 theater in the quiet Denver suburb of Aurora at about 1:30 a.m. yesterday, police sources told The Post.
12 people were killed and Fifty-eight other people were injured.
