Students grieve as they leave a memorial honoring AJ Boik, who was killed when a gunman opened fire on moviegoers in Aurora, Colorado July 21, 2012. James Holmes, the man accused in a shooting rampage at a Denver-area premiere of the new "Batman" film, received a high volume of deliveries in recent months, police said on Saturday, parcels they believe contained ammunition and bomb-making materials and showed evidence of "calculation and deliberation."
