James Holmes, the suspect in the shooting that killed 12 and injured 58 in a Colorado movie theater, spent $15,000 on weapons, ammunition and other equipment over the past several months and had 90 packages delivered to his workplace, a law-enforcement official said.
A search of Holmes’s apartment in Aurora, Colorado, revealed 30 improvised hand grenades and several containers filled with gunpowder and gasoline and an additional 10 gallons of fuel, said the official, who asked for anonymity because he was not authorized to speak about the investigation. The official said he was briefed on the matter.
Holmes, 24, is being held at the Arapahoe County jail and awaits arraignment Monday morning.
Police are investigating deliveries to both Holmes’s apartment and workplace at the University of Colorado, where Holmes was a graduate student in neurosciences, said Jacki Kelley, a spokeswoman for the multi-agency investigation. She declined to confirm the contents of Holmes’ apartment, which she said police are continuing to search.
University of Colorado-Denver spokeswoman Jacque Montgomery didn’t immediately respond to a phone call.
CBS News earlier reported on Holmes’s spending and deliveries.
