Gunman posted his plans to psychiatrist

The package allegedly from the suspected shooter, James Eagan Holmes, 24, remained unopened in a mailroom, perhaps for as long as a week before its discovery on Monday, FoxNews.com said, citing a law enforcement source.
The FoxNews.com report said FBI agents and police were called to the Anschutz medical campus of the University of Colorado in Aurora on Monday morning after a psychiatrist, who is also a professor at the school, reported receiving a package believed to be from the suspect.
