The attacker, 45-year-old Henry Bello, went to the hospital with an AR-15 rifle. He concealed his weapon by using a lab coat, The New York Times reported.

What police know about the gunman

Bello worked at the hospital for six months before sexual harassment accusations surfaced. He was hired in August of 2014 and left by February 2015. He resigned due to the workplace sexual harassment report.

Ten years before the 2014 sexual harassment claim, Bello was arrested and charged with sex abuse and unlawful imprisonment. During the 2004 incident, a 23-year-old woman told police he grabbed her near the crotch area outside a building in Manhattan. He also tried to penetrate the woman through her underwear after he allegedly lifted her up in the air. Bello later pleaded guilty to the unlawful imprisonment charged and was punished with community service. The sexual abuse charge was no longer in force.

Gunman’s target was not at work, shot another doctor

Bello apparently wanted to shoot 48-year-old Dr. Kamran Ahmed. According to Daily Mail, Bello looked for Ahmed and accused the latter of ruining his career.

Aside from the female doctor killed, six others were badly injured from the shooting rampage by Bello. The female doctor was identified as Tracy Sin-Yee Tam.
