The sources did not know what the officer approached by Dr. Lynne Fenton did with the information she passed along. They said, however, that the officer was recently interviewed, with an attorney present, by the Aurora Police Department as a part of the ongoing investigation of the shooting.

Fenton would have had to have serious concerns to break confidentiality with her patient to reach out to the police officer or others, the sources said. Under Colorado law, a psychiatrist can legally breach a pledge of confidentiality with a patient if he or she becomes aware of a serious and imminent threat that their patient might cause harm to others. Psychiatrists can also breach confidentiality if a court has ordered them to do so.

“For any physician to break doctor-patient confidentiality there would have to be an extremely good reason,” said Dr. Carol Bernstein, a psychiatrist at NYU Langone Medical Center and past president of the American Psychiatric Association.
