An off-duty New York City police officer and an executive at an investment firm were among the four people killed by a gunman at a Manhattan office tower.
The officer, Didarul Islam, 36, was working a corporate security detail Monday at the midtown skyscraper that is home to the headquarters of both the NFL and Blackstone, one of the world’s largest investment firms. Wesley LePatner, a senior managing director at Blackstone, also was fatally shot, the firm confirmed. A labor union identified a security officer killed in the shooting as Aland Etienne. Authorities haven't identified the other person killed in the attack.
