Colorado shooting: 'James Holmes threatened professor'
Denver: The suspect in the deadly Colorado theater attack threatened a professor and was banned from his university campus before one of the worst mass shootings in US history, prosecutors said on Friday.
Newly released court documents gave an important look at a case whose details have been kept largely out of public view.
James Holmes faces 152 charges in the July shooting at a midnight premiere of the latest Batman movie that killed 12 people and injured 5.
His lawyers argue he is mentally ill, raising the possibility that Holmes will plead not guilty by reason of insanity. The defense has a psychiatry expert on its defense team and plans to use him as an expert, the documents show.
The documents say the threats to the professor are why the University of Colorado revoked Holmes' access to campus. The name of the professor Holmes threatened has been blacked out. Prosecutors say the professor reported the threats to the university.
That conflicts with the university's statements that Holmes was denied access to non-public parts of the campus because he had withdrawn from school.
University officials did not immediately return a message seeking comment.
Just minutes before the shooting, Holmes tried unsuccessfully to call his university psychiatrist, defense attorneys have said.
Holmes also mailed a notebook to psychiatrist Lynne Fenton, a professor at the school, including violent descriptions of an attack, attorneys said.
She never received the package addressed to her, and it wasn't discovered in a university mail room until after the shooting.
Defense attorneys don't want the notebook to be used as evidence, saying it's protected by doctor-patient privilege. Prosecutors have said the doctor-patient relationship ended on June 11, weeks before the attack, when Fenton last saw Holmes professionally.
In other court documents, defense attorneys say the prosecutors' allegations are false, based on university statements. The university has said Holmes was denied access to non-public parts of the campus because he had withdrawn from school.
