Right before closing time just outside of new york city, at least one shot was fired bringing hundreds of area law enforcement officers to the scene. Good evening to you. No injuries reported so far. That's the headline and the good news. But officers are still trying to figure out what happened here. Witnesses say they saw a shooter wearing an all black biker helmet and they heard a gunshot. Police were able to find one single shell casing inside this mall somewhere near the nordstrom store but again we don't know exactly what happened here, why that gunman would have done this. So lots to figure out here. Thank you for that. Abc will stay on the story overnight and have the latest on good morning america.
