A New York City office building where a gunman killed four people then himself has reopened a week after the deadly shootings. On Monday, workers trickled back into 345 Park Avenue in Midtown Manhattan, a skyscraper home to high-profile tenants including the NFL and asset management firm Blackstone.

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.
