Nigerian-born doctor kills one, injures six at New York 120-year-old hospital before killing self

Two law enforcement officials say the doctor who opened fire at a New York City hospital where he used to work resigned in 2015 in lieu of being fired.
The law enforcement officials told The Associated Press that Dr. Henry Bello used an AR-15 to kill a fellow doctor and injure six other people at Bronx Lebanon Hospital on Friday afternoon.
Mayor Bill de Blasio says the Nigerian-born doctor had the weapon concealed in his white lab coat.
It was not immediately clear why he would have been fired.
The officials were not authorized to speak publicly and spoke to The Associated Press on condition of anonymity.
The 120-year-old hospital has nearly 1,000 beds and one of the busiest emergency rooms in New York City. It is about a mile and a half north of Yankee Stadium.
The gunman fatally shot himself after first trying to set himself on fire, they said.
Authorities described a chaotic scene at Bronx Lebanon Hospital as gunfire erupted at around 2:50 p.m., spreading terror throughout the hospital as employees locked themselves inside rooms and patients feared for their lives.
“I thought I was going to die,” said Renaldo Del Villar, a 55-year-old patient who was in the third-floor emergency room getting treatment for a lower back injury.
Law enforcement officials identified the shooter as Dr. Henry Bello, who was described on the hospital website as a family medicine physician.
He resigned from the hospital in 2015 after some sort of dispute, according to one law enforcement official, who said Bello used an AR-15 in the attack.
Ultimately, one female doctor was killed and six others wounded, de Blasio said.
“This was a horrible situation unfolding in a place that people associated with care and comfort, a situation that came out of nowhere,” de Blasio said.
The FBI tweeted that they had found “no nexus to terrorism” so far.
Shortly after receiving a 911 call about an active shooter, police officers went floor by floor, their guns drawn, looking for the gunman.
They learned just before 4 p.m. he was dead inside the building.
De Blasio confirmed that Bello killed himself, while Police commissioner James O’Neill said he tried to set himself on fire.
Employees and their loved ones described the horrifying moments as they scrambled for information.
Garry Trimble said his wife, hospital employee Denise Brown, called him from inside the hospital shortly after 3 p.m.
“She woke me up and told me there was a situation, somebody’s out there shooting people,” Trimble said as he waited for his wife to come out. “I could hear in her voice she was shaking and about to cry.”
Gonzalo Carazo described the scary scene to WCBS-TV. “I saw one of the doctors and he had a gunshot wound to his hand,” Carazo said.
“All I heard was a doctor saying, “Help, help!” Carazo locked himself in a room for about 15 minutes until police came and led him out of the hospital.
