A psychiatrist, who once treated accused cinema gunman James Holmes, described him as having had "homicidal thoughts" five weeks before he allegedly killed 12 moviegoers.
Dr. Lynne Fenton, from the University of Colorado, told a campus police officer that Holmes had threatened her in email and text messages, according to disclosed court documents.
Her statement has been released as one of numerous court documents unsealed by the judge assigned to the case earlier this week.
Defence lawyers have previously disclosed that Holmes had been a psychiatric patient of Fenton, who was then medical director for student mental health services at the University of Colorado-Denver Anschutz Medical Campus.
Fenton was also a member of the campus-based behavioral assessment and threat assessment team, which helps faculty and staff deal with "individuals who may be threatening, disruptive or otherwise problematic," according to that group's website.
It was not clear whether Fenton was caring for Holmes under the threat-assessment programme or under routine counseling she provided to students on campus.
Holmes, now 25, is accused of opening fire inside a packed cinema in the Denver suburb of Aurora on July 20, 2012, during a midnight screening of the Batman film "The Dark Knight Rises."
Prosecutors in the case of James Holmes, who is accused of killing 12 people in the 'Batman cinema shooting' in the US last July, have said that defence lawyers have not made a legitimate offer for him to plead guilty, according to reports.
Court papers had suggested that Holmes would be prepared to plead guilty in return for avoiding the death penalty – but prosecutors say the offer cannot be considered.
"The prosecution indicated that it could not consider such an offer without specific additional information, which the defense refused to provide," prosecutors said in their motion, according to the Denver Post newspaper.
