Gunman saw self as victim

To his dying breath, Dr. Henry Bello saw himself as the one true victim — even as the linoleum floors of Bronx-Lebanon Hospital turned red with the blood of his casualties.

“Why didn’t you help me out when I was in trouble?” Bello (right), 45, demanded as he pulled his assault rifle from his white lab coat and took aim at a doctor he felt had slighted him more than two years ago.

“Gun! Gun! Gun!” Dr. Roger Green yelled, fleeing as Bello fired and missed — the first salvo of Friday’s rampage, which left one dead and six wounded.

Bello had been forced to resign as a family-medicine doctor at the busy Bronx hospital in February 2015 — due to his own behavior.

He had been confrontational and was impossible to work with, according to multiple accounts.

“He was a hothead,” said one source. “He picked fights with his co-workers.”

One colleague accused him of sexual harassment, another said.

The hospital, alarmingly, didn’t know the worst of it. In 2003, a woman accused him of grabbing her by the crotch and arms and dragging her.

Bello pleaded guilty to misdemeanor unlawful imprisonment in 2004, and was sentenced to community service, a case hospital officials on Saturday claimed had not shown up on his record when they hired him.

“All the time, he was a problem,” said Bronx-Lebanon’s Dr. David Lazala, who helped train the Nigerian-born Bello, who received his medical degree in Dominica.

At previous jobs, Bello had also blamed everyone but himself for any bad fortune. He had lost a radiology technician position at Metropolitan Hospital in 2012 after he mishandled medication.

“He took medication to the wrong floor and violated safety procedures,” recalled his former lawyer, David Wims. Still, Bello could be charming. “I was so impressed with him,” Wims told The Post. “We discussed the possibility of setting him up [on a date] with my assistant. I told her, ‘You should go out with him. He’s a doctor.’ ”

Two years after losing the Metropolitan position, Bello lost a pharmacy-technician job.

But it was losing his next job, the Bronx-Lebanon residency, that most rankled him.

In the months after leaving, he fired off threatening e-mails, texts and calls to former colleagues, in particular dementia specialist Mohammed Ahmed, 48, who he believed had somehow barred his path from hospital resident to New York-licensed physician.

Bello would even tell his tale of woe at the Midtown homeless shelter where he lived for a time this year, again painting himself as a victim of others’ senseless vendettas.

“People were doing him wrong,” Tony Tompkins, 57, said his neighbor on the fourth floor the East 30th Street shelter would tell him, in explaining why a doctor could be homeless.

“Doing him dirty.”
