Massacre suspect bought 6000 rounds, police focus on booby-trapped home
A day after a gunman opened fire at a packed midnight showing of the new "Batman" film in a Denver suburb, killing 12 people and wounding 59 more, police on Saturday prepared to neutralise explosives in the suspects booby-trapped apartment.
Dozens of law enforcement officials arrived at the apartment of suspect James Holmes at dawn, but it was not immediately clear if they planned to detonate the suspected explosives using a robot. Police have evacuated five nearby buildings and created a perimeter of several blocks.
Meanwhile, a memorial of flowers and candles has been set up at the Aurora shopping mall where the shooting rampage at a showing of "The Dark Knight Rises" turned a movie screening into a chaotic scene of dead or bleeding victims. A handwritten sign read: "7/20 gone not forgotten."
The gunman -- armed with an assault rifle, a shotgun and a pistol, and wearing a full suit of tactical body armour, a helmet and a gas mask -- set off two smoke bombs before opening fire in the dark theatre.
Police said 30 people remained hospitalised on Saturday, 11 of them in critical condition.
Officers who arrived on scene within 90 seconds of the first emergency calls quickly took Holmes, 24, into custody in a parking lot behind the cinema, where he surrendered without a fight, Aurora Police Chief Dan Oates said.
Holmes, a graduate student who authorities said had his hair dyed red and called himself "the Joker" in a reference to Batman's comic-book nemesis, was due to make an initial court appearance on Monday.
Authorities were unable to enter Holmes' apartment, on the top floor of a three-story building, saying he had booby-trapped it with what appeared to be sophisticated explosives.
Police declined to say what, if anything, Holmes said to them following his arrest. During an emotional press conference, Oates would not comment on possible motives for the massacre that stunned the community and the nation.
President Barack Obama called the shootings a reminder that life is fragile and promised that the federal government stood ready to do all it could to seek justice for the "heinous crime."
"Even as we come to learn how this happened and who's responsible, we may never understand what leads anyone to terrorise their fellow human beings," Obama said in his weekly radio and Internet address, which was broadcast on Saturday.
Witnesses at the movie theater told of a horrific scene, with dazed victims bleeding from bullet wounds, spitting up blood and crying for help. Among those taken to hospitals as a precaution was a baby boy just a few months old.
"I slipped on some blood and landed on a lady. I shook her and said, 'We need to go; get up,' and there was no response, so I presumed she was dead," said Tanner Coon, 17.
The suspect may have blended in with other moviegoers who wore costumes as heroes and villains, and some witnesses said they believed at first that his appearance was a theatrical enhancement to the film.
"It was just straight chaos," said Jennifer Seeger, 25. "Everybody was starting to scream and run at that point. He went straight from here to here with a gun in my face at that point. That rifle was in my face and I honestly didn't know what to think."
The shooting evoked memories of the 1999 massacre at Columbine High School in Littleton, 27 km from Aurora, where two students opened fire and killed 12 students and a teacher.
It also resonated in the U.S. presidential race. Both Obama and his Republican rival, Mitt Romney, toned down their campaigns, pulled their ads from Colorado and dedicated their scheduled events to the victims.
The gunman was armed with an AR-15 assault rifle, a 12-gauge shotgun and a Glock .40-caliber handgun, Oates said. Police found an additional Glock .40-caliber handgun in his car, parked just outside the theatre's rear emergency exit, he said.
Holmes had purchased the weapons legally at three area gun stores in the last 60 days and had bought 6,000 rounds of ammunition, Oates said.
A law enforcement official who asked to remain anonymous said the suspect had purchased a ticket, entered the theatre and propped open the emergency exit while he slipped out to "gear up" and return armed.
The portrait of Holmes that emerged in the hours following the shooting remained fuzzy, with only a speeding ticket on his record and nothing to suggest he was capable of an outburst of gun violence.
Holmes' family issued a statement of sympathy for the victims, saying: "Our heart goes out" to their loved ones, while they also asked for privacy from the media while they "process this information."
