Police may have been tipped off about James Holmes’s behavior weeks before the 24-year-old opened fire at a Colorado movie theater, killing 12 people, ABC News reports. Dr. Lynne Fenton, the psychiatrist who treated Holmes at the University of Colorado, where he was a student, reportedly told a university police officer that she had concerns about his behavior. Under Colorado law, a psychiatrist can break patient confidentiality if he or she believes the patient is a serious and imminent threat. “For any physician to break doctor-patient confidentiality there would have to be an extremely good reason,” says Dr. Carol Bernstein, a psychiatrist at NYU Langone Medical Center.
