The death toll is now two in a Boston hospital shooting.

Police said late Tuesday the doctor who was gunned down at Brigham and Women's Hospital has died.

Dr. Michael Davidson succumbed to his injuries hours after a man walked into the hospital and asked to speak with Davidson.

The gunman, who has been identified by police as Stephen Pasceri, fired two shots at the doctor.

Pasceri was later found dead of what's believed to be a self-inflicted gunshot wound.

Detectives are still looking into a possible motive.
