FoxNews is reporting that the man accused of killing 12 people and injuring more that 50 in the Aurora, Colorado theater shooting may have sent his plan of action to a psychiatrist. The reports says James Holmes mailed a notebook "full of details about how he was going to kill people" to a University of Colorado psychiatrist before the attack.

According to the FoxNews report, Holmes mailed a package to the doctor, but it remained unopened in a mailroom for as long as a week before its discovery Monday.  The FoxNews.com report said Police and FBI agents were called to the University of Colorado Anschutz medical campus in Aurora on Monday morning after the psychiatrist, who is also a professor at the school, reported receiving a package believed to be from the suspect.
