The widow of a cardiac surgeon shot and killed at a Boston hospital by his patient's son has given birth to a baby girl less than three months after the doctor's death.

Brigham and Women's Hospital announced Monday that Mikaela Jane Davidson was born April 4.

Mikaela's father, Dr. Michael Davidson, was killed at the hospital on Jan. 20, leaving behind his wife, Dr. Terri Halperin, daughters age 10 and 8 and a 2-year-old son.

Halperin said in a statement, "At a time when my children and I are completely heartbroken over the loss of Michael, we are finding joy in Mikaela's arrival."

Police say Davidson was shot by Stephen Pasceri, who then killed himself. Relatives say Pasceri may have held Davidson responsible for the death of his mother.
