Blackstone told employees on Friday it will reopen its New York headquarters on August 4, a week after shuttering it in the wake of a shooting that killed four people including one of its executives.

A gunman opened fire inside the Manhattan skyscraper that is the headquarters of private-equity firm Blackstone and the NFL, killing four people, including a police officer, before fatally shooting himself on Monday evening, authorities said. Another person was in critical condition, and others suffered less serious injuries.
