New details are emerging about James Holmes, , the suspect in the Aurora movie theater shooting that left 12 dead and 58 injured, and exactly when he decided on plotting the horrific attack.
Fox News reports that Holmes mailed planned details of his rampage to a University of Colorado psychiatrist before the July 20 attack. Law enforcement sources say the unopened package sat in a mailroom for a week before it was discovered on Monday, July 23.
Police and FBI were called to the University's Anschutz Medical Campus on Monday after the psychiatrist reported receiving the package from Holmes.
The initial package turned out to be harmless, however, a search turned up another package. The second package contained a notebook documenting the details of Holmes's planned attack.
The drawings were detailed and reportedly depicted his every planned move.
"There were drawings of what he was going to do in it - drawings and illustrations of the massacre," a source told the network.
