The psychiatrist treating suspected Aurora gunman James Holmes was so concerned about her patient’s behavior that she contacted University of Colorado police six weeks before the shooting, ABC News reports.

Dr. Lynne Fenton became so alarmed with the 24-year-old Ph.D candidate in early June that she contacted campus police and reached out to the chairman of the university’s Behavioral Evaluation and Threat Assessment team, Denver’s ABC7-TV reported.

ABC News did not know how the officer responded to the information, but confirmed that the officer was recently interviewed by the Aurora (Colo.) Police Department as part of an investigation of the July 20 shooting.
