Dr. Michael Davidson, a cardiovascular surgeon who was shot twice on the second floor of Brigham and Women’s Hospital this morning, has died. The suspected shooter, Stephen Pasceri, died earlier of a self-inflicted gunshot wound.

Davidson, 44, of Wellesley, was shot at the hospital’s Carl J. and Ruth Shapiro Cardiovascular Center. The incident began just after 11 a.m., when police say Pasceri came into the building asking for Davidson. Police said they don’t yet know what the suspect’s motive was.

“There’s something in the past that upset this guy to come in looking for this particular doctor,” Police Commissioner William Evans said at a press conference.
