Colo. suspect's family: 'Hearts go out to' victims

When the smoke 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. They saw a silhouette of a person in the haze near the screen, first pointing a gun at the crowd and then 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 of ties to any terrorist groups.

Holmes had an assault rifle, a shotgun and two pistols, a federal law enforcement official said, speaking on the condition of anonymity to discuss the ongoing investigation.

FBI agents and police used a hook and ladder fire truck to reach Holmes' apartment in Aurora, police Chief Dan Oates said. They put a camera at the end of a 12-foot pole inside the apartment, and discovered that the unit was booby trapped. Authorities evacuated five buildings as they tried to determine how to disarm flammable and explosive material.

Victims were being treated for chemical exposure apparently related to canisters thrown by the gunman. Some of those injured are children, including a 4-month-old baby who was released from the hospital.

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.

Police released a written statement from Holmes' family: “Our hearts go out to those who were involved in this tragedy and to the families and friends of those involved.”

The movie opened across the world Friday with midnight showings in the U.S. 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 the U.S. since the Nov. 5, 2009 attack at Fort Hood, Texas, when an Army psychiatrist killed 13 soldiers and civilians and more than two dozen others wounded.

In Colorado, it was the deadliest since the Columbine High School massacre on April 20, 1999, when two students opened fire at the school in the Denver suburb of Littleton, killing 12 classmates and a teacher and wounding 26 others before killing themselves.

The mall in Aurora, the state's third-largest city, has been the scene of violence before.

In July 2001, two men were shot and wounded inside the mall following an argument. In June 2005, a woman was killed and her boyfriend and a bystander were wounded following an argument inside the mall. Two men were arrested in that case, at least one of whom was sentenced to life in prison.
