The man accused of killing a dozen people at a midnight screening of the 'The Dark Knight Rises' sent a journal detailing the rampage to a University of Colorado psychiatrist prior to the attack, only for it to go untouched in a campus mailroom, 

The diary of 24-year-old James Holmes -- "full of details about how he was going to kill people" -- was discovered Monday by authorities investigating another package at the school's Anschutz medical campus in Aurora, a law enforcement official told the network. The source also said that the package had been in the mailroom since July 12.
