Who was the hospital gunman?

A former Bronx-Lebanon Hospital employee named Dr. Henry Bello returned with a rifle hidden under his white lab coat and opened fire Friday, killing a female doctor and wounding six others before taking his own life, according to police sources. Dr. Bello was a family medicine physician at the hospital until he resigned in 2015 in lieu of being fired over sexual harassment allegations, law enforcement officials told the Associated Press. It is unclear why he was still listed on the hospital's website on Friday afternoon.
