On Monday afternoon, Sebije Nelovic, a cleaner at 345 Park Avenue in Midtown, Manhattan, began her daily sweep of the glassy high-rise building where she has worked for 27 years. Two hours into her shift, she heard gunshots. "Suddenly, the glass door was shaking. It started falling down – boom. And this guy came in the middle of the door, and pointed his gun at me," she said in the statement. "He started shooting around me. I put my hands up and said, 'I'm a cleaning lady. I'm a cleaning lady.'"
