Now it would appear that Holmes sent a package to a University of Colorado Psychiatrist that sat in their mail room UNOPENED since July 12th (it wasn't opened until this Monday when it was discovered while investigating another package that turned out not to be from him):

James Holmes Sent Notebook to Psychiatrist Before Shootings


What was inside the package you ask? None other than a notebook complete with his plans, diagrams, and drawings on how he was going to go on the murderous rampage that he ultimately did. DEFINITELY looks like a REAL opportunity was missed to prevent this from happening.
