A psychiatrist who treated suspected movie-theater killer James Holmes reported unspecified concerns about him to a University of Colorado police officer before the July 20 attack at the Century Aurora 16, ABC News reported Monday, citing unnamed sources.

The report followed earlier disclosures that Dr. Lynne Fenton, identified in court documents as Holmes’ psychiatrist, had alerted a threat-assessment team at CU’s Anschutz Medical Campus to concerns about him.

The campus’ Behavioral Evaluation and Threat Assessment team took no further action after Fenton reported Holmes to several of its members in June, The Denver Post reported Friday.

University officials have repeatedly refused to answer questions about Holmes, citing a gag order.

Holmes, 24, faces 24 counts of first-degree murder and 116 counts of attempted murder in the attack, which was carried out early July 20 during the premiere of the new Batman film, “The Dark Knight Rises.”

Twelve people died, and 58 others were injured, several of them critically, in the incident.

It was not clear what the police officer who was contacted by Fenton did with the information, ABC News reported.

Sources told ABC News that the officer — who was not identified in the report — recently was interviewed by Aurora police detectives with an attorney.

As a medical doctor, Fenton would generally be bound to respect Holmes’ right to privacy — except in a case where she perceived a serious threat to others. Under a federal rule followed by psychiatrists, Fenton had a duty to take action if Holmes told her of a specific plan to harm others.

The revelation that Fenton was Holmes’ psychiatrist came in a motion by Holmes’ defense attorneys made public recently. That information has since been blacked out in the document posted on the Colorado State Judicial Branch’s website.

Holmes had sent a package with a notebook to Fenton before the attack, according to court papers made public last week.
