AURORA, CO (WKOW) – The University of Colorado said it's investigating whether shooting suspect James Holmes used his position as a graduate student to order deadly booby trap material found in his apartment.
Police said Holmes received deliveries over a span of four months to his home and school. The police have not identified the contents.
University spokeswoman Jacque Montgomery said the school is looking into those packages received at school.
Police said Holmes opened fire in a theatre during a packed midnight showing of the new Batman movie early Friday, killing 12 and injuring 58. Authorities said it took hours for bomb experts to dismantle a complicated web of trip wires and explosives located inside Holmes apartment.
Montgomery said Holmes withdrew from the university's Ph.D. neuroscience program without giving a reason.
