Shootings 'planned for months'
Deliveries received by the man accused of committing a cinema massacre at a Denver-area premiere of the new Batman film suggest months of "calculation and deliberation" leading up to the shooting rampage that killed 12 people, police said.
Aurora Police Chief Dan Oates discussed the shipments as local and federal authorities completed the painstaking process of disarming suspect James Holmes' apartment, which was found booby-trapped with explosive devices after the shooting at a multiplex theatre several miles away.
Yesterday, the local coroner's officer released the names of the 12 people killed. As evening fell, residents gathered at a local high school to mourn the passing of a classmate who graduated in May.
"We've become aware that the suspect over the last four months received a high volume of deliveries to both his work and home addresses," Mr Oates said.
"This begins to explain how he got his hands on all the magazines and ammunition.
"We also think it begins to explain some of the materials he had in his apartment," Mr Oates said.
"What we're seeing here is evidence of some calculation and deliberation."
A gunman wearing a full suit of tactical body armour, helmet and gas mask opened fire at a packed midnight showing of The Dark Knight Rises early on Friday morning, killing 12 people and wounding 58.
Mr Holmes (24) was arrested minutes later in a parking lot behind the cinema.
Among the dead were a 6-year-old girl who had just learned to swim, a young man celebrating his 27th birthday and an aspiring sportscaster who missed by minutes being on the scene of a Toronto mall shooting earlier this summer.
Jessica Ghawi, also known as Jessica Redfield, had blogged at length about surviving the June 2nd Eaton Centre mall shooting in Toronto that killed two people and injured several others.
Friday’s mass shooting stunned the nation, evoking memories of the 1999 massacre at Columbine High School in Littleton, 27km from Aurora, where two students opened fire and killed 12 students and a teacher.
It also reverberated in the US presidential race.
Both US president Barack Obama and his Republican rival, Mitt Romney, toned down their campaigns on Friday, pulled ads from Colorado and dedicated scheduled events to the victims.
Mr Obama was scheduled to travel to Colorado today to honour the shooting victims, an administration official said.
Pope Benedict expressed dismay and sadness at the shooting."I was deeply shocked by the senseless violence which took place in Aurora, Denver," he said in his regular Sunday Angelus address."I share the distress of the families and friends of the victims and the injured, especially the children," he said.
Those who witnessed the shooting told of a horrific scene, with dazed victims bleeding from bullet wounds, spitting up blood and crying for help.
"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).
When police arrested Holmes, he was armed with an AR-15 assault rifle, a 12-gauge shotgun and a Glock .40-caliber handgun, Mr Oates said.
Police found an additional Glock .40-caliber handgun in his car, parked just outside the theatre's rear emergency exit, he said.
Police said Mr Holmes had purchased the weapons legally at three area gun stores in the last 60 days and bought 6,000 rounds of ammunition online, including a 100-round drum magazine for an assault rifle.
Arapahoe County Sheriff Grayson Robinson said the suspect was being held in solitary confinement to protect him from other prisoners, a routine move in high-profile cases.
Mr Holmes, who authorities said had dyed his hair red and called himself "the Joker" in a reference to Batman's comic-book nemesis, was due to make an initial court appearance tomorrow.
Little has surfaced from Mr Holmes's past to suggest he was capable of such violence.
Until last month, he was studying for a doctoral degree in neuroscience at the University of Colorado's Anschutz Medical School, a few blocks from his apartment.
A top student, he had earned a prestigious federal grant from the National Institutes for Health to support his studies.
The grants are intended for "outstanding neuroscientists and academicians who will make significant contributions to neurobiology," university spokeswoman Jacque Montgomery said.
Mr Holmes had spent a year in the doctoral program, where a fellow student described him as quiet and studious, before he abruptly withdrew from the university last month. He gave no reason for his departure.
Mr Holmes kept a low profile off campus as well. He was not active under his own name on social media sites like Facebook and both the landlord and fellow tenants of his red-brick apartment building said they knew little about him.
Neighbours who met him in the local bar described him as relaxed and friendly, though a few recalled him displaying brief flashes of anger over seemingly trivial exchanges.
The University of Colorado Hospital, which treated some of the shooting victims, said 10 people had been released and five remained in critical condition.
The Medical Center of Aurora said four of its seven patients remained in the intensive care unit, while three others were on the main trauma floor.
A memorial of flowers, candles and stuffed animals quickly sprung up where the shooting rampage took place.
A handwritten sign read: "7/20 gone not forgotten."
At the evening memorial service at Gateway High School, shooting victim and recent graduate AJ Boik was remembered as beloved former student and talented artist who was bound for college in the fall.
"He was a very big part of this community," said Tami Avery, whose son played sports with Boik.
"He will be dearly missed."
After the shooting rampage, police went to Mr Holmes' apartment, where they found booby traps that prevented investigators from entering for two days and forced officials to evacuate the apartment complex and five nearby buildings.
Sources familiar with the investigation said that some 30 shells filled with gunpowder were spread through the 800-square-foot apartment and wired to a control box in the kitchen.
There were also at least two containers filled with "incendiary liquids" intended to fuel a fire from the initial explosions, and an undetermined amount of bullets meant to ricochet around the apartment.
"Given the amount of explosives that were there, if they detonated ideally, you would have had a very ample explosion with an ensuing thermal effect from the incendiary liquids that would have destroyed that apartment complex," a law enforcement official said.
Local and federal bomb experts used a remote-controlled robot to disable two trip wires, then detonated a tube known as a "water shot" to disable the control box.
By yesterday afternoon, police had removed the last of the devices, packed them in sand in a dump truck and drove them away.
Authorities said they were working carefully to preserve any evidence in the apartment, which could shed light on the motives for a crime that stunned Aurora and much of the nation.
