 NEW YORK (AP) — A doctor angry that his career was derailed at a New York City hospital toted an assault rifle past security in search of a colleague he was going to hold responsible. When that person wasn't there, he opened fire anyway, killing a doctor who was only there covering a shift as a favor, authorities said Saturday. 
  
 The new details of Dr. Henry Bello's rampage emerged along with an email rant against colleagues he blamed for forcing him to resign from Bronx Lebanon Hospital amid sexual harassment allegations two years earlier. The email was sent to the New York Daily News just two hours before the shooting Friday afternoon that left six other people wounded and Bello dead from a self-inflicted shot. 
  
 "This hospital terminated my road to a licensure to practice medicine," the email said. "First, I was told it was because I always kept to myself. Then it was because of an altercation with a nurse." 
  
 He also blamed a doctor for blocking his chances at practicing medicine. 
  
 Bello had warned his former colleagues when he was forced out in 2015 that he would return someday to kill them. 
  
 A law enforcement official told The Associated Press that Bello arrived at the hospital with the assault rifle hidden under his lab coat and asked for a specific doctor whom he blamed for his having to resign, but the physician wasn't there at the time. The official spoke on anonymity because the person was not authorized to discuss an ongoing investigation. 
  
 It was not clear if Bello knew Dr. Tracy Sin-Yee Tam, 32, who was killed in the shooting on the 16th and 17th floors of the hospital and was, like him, a family medicine doctor. Hospital officials said that Tam normally worked in one of the hospital's satellite clinics and was covering a shift in the main hospital as a favor to someone else. 
  
 "It makes you think that anything can happen to anybody," said Tam's neighbor, Alena Khaim, 23, who saw Tam's sister outside the home Friday night overcome with grief, shaking and unable to walk. "She was such a sweet girl. You would never think something like that would happen but it happened." 
  
 Judy Beckles-Ross, 46, said she's not surprised Tam volunteered to cover the shift. 
  
 "She never said no," said Beckles-Ross, a friend from medical school who knew her for 11 years. "She had a good heart. Anybody that needed help, she would help them." 
  
 The six others who were injured — a patient, two medical students and three physicians — largely suffered gunshot wounds to the head, chest and abdomen. One physician remained in critical condition and the rest were stable, officials said Saturday. 
  
 Hospital vice president Errol C. Schneer said his staff responded heroically. 
  
 "Many of our staff risked their own lives to save patients," Schneer told reporters at the hospital where the 16th and 17th floors remained closed, and staffers were still recovering from the rampage that sent people diving for cover and huddling in patients' rooms while the gunman was on the loose. Adding to the chaos, authorities said, was a fire alarm that went off when Bello attempted to set himself ablaze, the flames extinguished by sprinklers, shortly before he shot himself. 
  
 Detectives searched the Bronx home where Bello was most recently living and found the box where the gun came from. Investigators were checking serial numbers and trying to determine where it was purchased. 
  
 His former co-workers described a man who was aggressive, loud and threatening. 
  
 "All the time he was a problem," said Dr. David Lazala, who trained Bello as a family medicine doctor. When Bello was forced out in 2015, he sent Lazala an email blaming him for the dismissal. 
  
 Dr. Maureen Kwankam told the New York Daily News that "he promised to come back and kill us then." 
  
 According to New York State Education Department records, Bello graduated from Ross University and had a permit to practice as an international medical graduate that was issued on July 1, 2014, and expired last year on the same day. 
  
 In 2004, the doctor pleaded guilty to unlawful imprisonment, a misdemeanor, after a 23-year-old woman told police Bello grabbed her. He was arrested again in 2009 on a charge of unlawful surveillance, after two different women reported he was trying to look up their skirts with a mirror. That case was eventually sealed. 
  
 Schneer told the New York Times that the hospital did not know about Bello's criminal history when he was hired. 
  
 "At that time, and as a result of a human resources and security department background check, which includes fingerprinting, there was no record of any conviction for sexual abuse," he said.

Output:
Two hours before he stormed through the Bronx-Lebanon Hospital, killing a female doctor and wounding six other people, Henry Bello sent an email to the New York Daily News outlining his disgruntlement that "this hospital terminated my road to a licensure to practice medicine. First, I was told it was because I always kept to myself. Then it was because of an altercation with a nurse." Bello names two doctors by name, saying he emailed one "congratulating her for my termination after she sent out an email to everybody telling them to file complaints against me so I can be terminated for being rude to her." He told her "it remains to be seen if my life is meaningless or disposable." Bello's email to the Daily News never explicitly threatened violence, notes Reuters. Bello asked for a doctor by name, notes the AP; when that person wasn't there, he opened fire anyway.
