Update: 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.
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, affiliated with Harvard Medical School, said in a statement the shooting took place in its Shapiro building, a cardiovascular care and research center.
