US Man Killed Doctor Over Mom's Death

              
Boston - A man who walked into a leading hospital, asked for a cardiac surgeon by name and fatally shot him outside an examination room had been upset about his mother's death and had blamed the doctor for it, relatives said.

Gunman Stephen Pasceri entered Brigham and Women's Hospital, which is associated with Harvard University, on Tuesday morning seeking Dr Michael Davidson and then shot him twice, police said. He then killed himself, and officers found his body with the weapon shortly afterward.

Pasceri's sister and brother said on Wednesday they were shocked by his actions and believe he held Davidson responsible for the November death of their mother, who had heart and lung problems.

Marguerite Joly told the Boston Herald her mother, Marguerite Pasceri, was Davidson's patient and her brother and the doctor had had "a fine relationship." She said she doesn't know why her brother snapped.
"I think it comes down to the fact that my brother thought it was the doctor's fault that my mother died," Joly said.
