“Police sources told ABC News the alleged killer, who resigned from Bronx-Lebanon Hospital Center in 2015 over allegations he sexually harassed a co-worker, went to the hospital’s 16th floor looking for the doctor against whom he held a grudge.
When he was told that the doctor wasn’t there, Bello opened fire, the sources said, wounding six people.
He then went to the 17th floor, where he encountered a female doctor in a hallway and fatally shot her, according to the sources….
Bello was a Nigerian national who went to medical school in the Caribbean, according to sources. He was not a licensed doctor in the U.S. but working under a limited state-issued permit. He had previously been issued a pharmacy technician license in California in 2006, around the time he was at University of Southern California, sources said.”
