Police say a doctor was shot inside a prestigious Boston hospital before the gunman killed himself.
Boston Police Commissioner William Evans says the physician was shot twice and suffered life-threatening injuries.
Evans says police were on the scene at Brigham and Women's Hospital within seconds after getting the first calls at about 11 a.m. Tuesday. The hospital is affiliated with Harvard Medical School.
Officers conducting a room-by-room search found the suspect dead of a self-inflicted wound in an examination room. The gun was also found.
No names have been released, and Evans did not disclose a motive. He said the suspect wasn't a patient of the doctor.
The hospital said in a statement the shooting took place in its Shapiro building, a cardiovascular care and research center.
