Terror at Blackstone: The Harrowing Hours at 345 Park Avenue

President Jon Gray calls the past day ‘brutal’

The alarm reached Jon Gray on the 44th floor, in his C-suite office high above Park Avenue: An active shooter was in the building.

In the lobby below, a gunman had opened fire, killing a uniformed police officer and two others who worked in the office tower. Then, the shooter fired at the turnstile, boarded an elevator and headed up.
