The suspect in the Colorado cinema massacre posted a notebook "full of details about how he was going to kill people" to a psychiatrist, it has been reported.
The advance warning of the mass killing - sent to the member of staff at the University of Colorado - lay unopened in a post room for as long as a week before its discovery on Monday, a police source told Fox News.
It is claimed that FBI agents were called to the university's 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.
It turned out to be from someone else, but a search of the post room on the campus uncovered another package sent to the psychiatrist with Holmes’ name in the return address, the broadcaster reported.
