NEW YORK: A man with a rifle killed an off-duty New York City police officer and three other people before taking his own life at a Manhattan office tower on Monday, according to officials. Law enforcement officials were working to unravel what took place and why this location may have been targeted in a city that had recently announced it was on pace to have its fewest people hurt by gunfire than any year in recent decades. What happened? A man exited a double parked BMW with an M4 rifle and then walked toward the building on Monday evening, according to surveillance video.

Police responded to reports of armed suspect and warned those around Park Ave in Manhattan to shelter-in-place
