Bello thereupon produced an Anderson Arms AR-15 assault rifle with a standard magazine. He began firing at the nurse’s station and then into an adjoining office.
“He’s aiming for and aiming at doctors,” a police official reports.
Bellow then took out a Gatorade bottle that he had filled with gasoline. He used it to set a fire before heading up to the 17th floor. He there encountered a female doctor. He shot her multiple times.
Another female doctor who had gotten to the 17th floor moments before took refuge and escaped his notice. She would later speak of the threats Bellow had uttered two years before about returning to kill.
