The psychiatrist treating James Holmes told a University of Colorado police officer that she was worried about her patient weeks before he allegedly killed 12 people in an Aurora movie theater.
The allegation that Dr. Lynne Fenton warned authorities about Holmes' potential to harm others -- reported by ABC News -- is the second time she told others he was possibly dangerous.
Fenton, a member of the university's threat assessment team, reportedly told other committee members that Holmes, a Ph.D neuroscience student potentially jeopardized campus safety.
Though ABC's anonymous sources said Fenton took her concerns to the university officer "several weeks before" the July 20 rampage that wounded 58 others, it's unknown how the cop handled the tip.
Fenton talked with several members of the Behavioral Evaluation and Threat Assessment team, too, but the full committee never launched an investigation into Holmes because the 24-year-old dropped out of the doctoral program about six weeks before the attack.
Doctors in Colorado can break confidentiality rules with patients if they become aware of imminent risks to others, Reuters reported.
Police say Holmes burst into the midnight premier of "The Dark Knight Rises" wearing riot gear, setting off smoke devices and firing indiscriminately into the audience. After being apprehended, he allegedly informed detectives that his home was booby trapped.
Holmes has been charged with 142 crimes, including 12 counts of first-degree murder with deliberation and 12 counts of first-degree murder with extreme indifference.
