A cardiac surgeon was shot inside Boston's Brigham and Women's Hospital Tuesday and later succumbed to his injuries, police said, and the suspected shooter was found dead in an examination room from an apparent self-inflicted gunshot wound.

"This evening, Dr. Michael J. Davidson, director of Endovascular Cardiac Surgery at Brigham and Women’s Hospital, has tragically died as a result of the gunshot wounds he sustained this morning during the shooting event at the Shapiro Cardiovascular Center," the hospital said in a statement late Tuesday.

The 44-year-old from Wellesley was shot twice, Boston Police Commissioner William Evans said in a midday news conference, before Davidson died.

"Dr. Davidson was a wonderful and inspiring cardiac surgeon who devoted his career to saving lives and improving the quality of life of every patient he cared for," the hospital statement added. "It is truly devastating that his own life was taken in this horrible manner."

Earlier Tuesday, Boston police identified the alleged shooter as Stephen Pasceri, 55, of Millbury.

Evans said the suspect asked for Davidson by name on the hospital floor.

"We know he came into the hospital, on the second floor, asking for this particular doctor," Evans said at the press briefing. "Why and for whatever reason, that's something we're looking into. But it wasn't clearly a case of a suspect coming in here, you know, just acting out."

Calls came in to police just after 11 a.m. for reports of a shooting in the hospital's Shapiro building. The building was then locked down by the hospital, before being reopened.

At the midday news conference, Brigham staff said they had trained for active shooter situations in the past.

Later in the day, some in the Boston hospital community told WBUR's Martha Bebinger that a training video they had watched had eerie similarities to the alleged circumstances of Tuesday's shooting.
