A court document filed Friday revealed Holmes was a patient of University of Colorado psychiatrist Lynne Fenton before the attack.

Sources told KMGH that Fenton contacted several members of a “behavioral evaluation and threat assessment” team to say Holmes could potentially be a danger to others, the station reported.

The “BETA” team consists of “key” staff members from various university departments who have specific expertise in dealing with assessing potential threats on campus, the school says on its website.

Holmes was a doctoral student at the university’s Anschutz Medical Campus until June, when he withdrew from the program.

Sources told KMGH that university officials never contacted Aurora police with Fenton’s concerns before the July 20 killings.
