BOSTON — A man stabbed a doctor while being treated at a psychiatric office at a Boston medical building Tuesday and was fatally shot by an off-duty security guard who happened by, police said.
The attack took place at a high-rise affiliated with Massachusetts General Hospital.
The doctor, identified by hospital officials as Dr. Astrid Desrosiers, was in serious but stable condition. Police said the man died of gunshot wounds. He was identified as Jay Carciero, 37, of Reading, Mass.
"During the course of the stabbing incident an off-duty security officer who was armed interceded. He produced a weapon and ordered the suspect to drop the knife. And when the suspect did not comply, he shot the suspect," said Boston Police Commissioner Ed Davis.
The security guard was not affiliated with the hospital and just happened to be on the fifth floor where the attack occurred, according to Bonnie Michelman, the hospital's security director.
"Certainly heroic -- we are happy he was here," Michelman said.
Carciero's sister-in-law, Lisa Carciero, said the family was devastated by the news and would not make public comments.
The attack took place at the Massachusetts General Hospital Bipolar Clinic & Research Program, in a building near the main hospital. The program provides clinical care, conducts research and educates the community about bipolar disorder, according to its website.
David Wert, who lives near the medical building, was home with his infant daughter when he saw the commotion outside and became worried about his wife, Alicia, who works on the second floor.
"We came out to see if Mommy was OK," said Wert, who was carrying his child. Police did not allow him in the building, but his wife called about five minutes later to say she was all right.
