AURORA, Colo. (AP) – A gunman in a gas mask barged into a crowded Denver-area theater during a midnight premiere of the Batman movie on Friday, hurled a gas canister and then opened fire, killing 12 people and injuring at least 50 others in one of the deadliest mass shootings in recent U.S. history.
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. Then they saw a silhouette of a person in the smoke near the screen, first pointing a gun at the crowd and shooting.
“There were bullet (casings) just falling on my head. They were burning my forehead,” Jennifer Seeger said, adding that the gunman, dressed like a SWAT team member, fired steadily except when he stopped to reload.
“Every few seconds it was just: Boom, boom, boom,” she said. “He would reload and shoot and anyone who would try to leave would just get killed.”
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.
Authorities did not release a motive. The FBI said there was no indication that the shooting is tied to any terrorist groups.
Victims are being treated for chemical exposure apparently related to canisters thrown by the gunman. Some of those injured are children, including a 3-month-old infant who was shot.
Aurora police spokesman Frank Fania on ABC's “Good Morning America” said he didn't know yet if all the injuries were gunshot wounds. He said some might have been caused by other things such as shrapnel.
The movie opened across the world Friday with midnight showings in the U.S. Guards were at a screening at a movie theater in New York's Times Square. The shooting prompted officials to cancel the Paris premiere, with workers pulling down the red carpet display at a theater on the famed Champs-Elysees Avenue.
President Barack Obama said he was saddened by the ”horrific and tragic shooting,” pledging that his administration was “committed to bringing whoever was responsible to justice, ensuring the safety of our people, and caring for those who have been wounded.”
It was the worst mass shooting in Colorado since the Columbine High School massacre on April 20, 1999. Students Eric Harris, 18, and Dylan Klebold, 17, opened fire at the school in the Denver suburb of Littleton, about 15 miles west of Aurora, killing 12 classmates and a teacher and wounding 26 others before killing themselves.
Friday's attack began shortly after midnight at the multiplex theater at a mall in Aurora, the state's third-largest city.
The film has several scenes of public mayhem – a hallmark of superhero movies. In one scene, the main villain Bane leads an attack on the stock exchange and, in another, leads a shooting and bombing rampage on a packed football stadium.
It was the final installment of the “Dark Knight” trilogy directed by Christopher Nolan, starring Christian Bale as Batman. The series has a darker tone than previous Batman incarnations. It is the follow-up to “The Dark Knight,” which won Heath Ledger a posthumous Oscar for his searing portrayal of The Joker.
The gunman released a gas that smelled like pepper spray from a green canister with a tag on it, Seeger said.
“I thought it was showmanship. I didn't think it was real,” she said.
Seeger said she was in the second row, about four feet from the gunman, when he pointed a gun at her face. At first, “I was just a deer in headlights. I didn't know what to do,” she said. Then she ducked to the ground as the gunman shot people seated behind her.
She said she began crawling toward an exit when she saw a girl about 14 years old “lying lifeless on the stairs.” She saw a man with a bullet wound in his back and tried to check his pulse, but “I had to go. I was going to get shot.”
Then the man began firing, starting with a shot toward the ceiling.
Witness Shayla Roeder said she saw a young teenage girl on the ground bleeding outside the theater. “She just had this horrible look in her eyes …. We made eye contact and I could tell she was not all right,” Roeder said.
Police, ambulances and emergency crews swarmed on the scene after frantic calls started flooding the 911 switchboard, officials said. Officers came running in and telling people to leave the theater, Salina Jordan told the Denver Post. She said some police were carrying and dragging bodies.
Hayden Miller told KUSA-TV that he heard several shots. “Like little explosions going on and shortly after that we heard people screaming,” he told the station. Hayden said at first he thought it was part of a louder movie next door. But then he saw “people hunched over leaving theater.”
Officers later found the gunman near a car behind the theater.
“A gas mask, rifle, handgun (and) at least one additional weapon (were) found inside,” Aurora police Chief Dan Oates said, adding that there was no evidence of any other attackers. The suspect spoke of “possible explosives in his residence. We are dealing with that potential threat,” Oates said.
A large truck lettered “bomb squad” arrived near an Aurora apartment complex where the suspect is believed to have lived, about four miles from the theater. Dozens of police squad cars, vans and other vehicles were already at the scene, along with black-clad officers carrying automatic weapons.
Police evacuated residents of the building. Oates did not say whether any explosives had been found. He said police also checked for explosives in the parking lot and at the Century 16 theater and secured those areas.
At least 24 people were being treated at Denver area hospitals.
“Warner Bros. and the filmmakers are deeply saddened to learn about this shocking incident. We extend our sincere sympathies to the families and loved ones of the victims at this tragic time,” the studio said.
The youngest victim reported was a 6-year-old being treated at Children's Hospital Colorado, where a total of six victims were taken. Their condition wasn't known. Two people in critical condition were rushed to nearby Swedish Medical Center, a spokeswoman said.
