Thousands of mourners last night attended an open-air vigil for the 12 victims of the Colorado shootings.
Cheers rang out as the names of the victims were read out and many carried banners and released balloons in tribute.
The other 11 victims were 26-year-old navy veteran Jon Blunk, student AJ Boik, 18, sports journalist Jessica Ghawi, 24, sailor John Larimer, 27, cinema-worker Matt McQuinn, 27, Subway sandwich worker Micayla Medek, 23, bartender Alex Sullivan, 27, psychology graduate Alexander Teves, 24, Air Force reservist Jesse Childress, 29, businessman Gordon Cowden, 51 and 32-year-old Rebecca Wingo.
Holmes has reportedly been moved into solitary confinement for his own protection.
Police said the rampage was planned with “calculation and deliberation”.
For months James Holmes received deliveries that authorities believe armed him for battle and were used to rig his flat with dozens of bombs.
Experts have now made Holmes' booby-trapped suburban Denver home safe.
It was rigged with bombs and dangerous chemicals and some of these materials were taken to a remote location and detonated in controlled explosions.
On Sunday President Barack Obama flew to Denver to meet with the victims’ families.
In an address to the nation, he described the massacre as a “heinous crime”.
