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.

Blackstone Inc. executive Wesley LePatner has been named as one of the four people killed in the mass shooting in New York on Monday evening.

The shooter, identified as Shane Devon Tamura, of Las Vegas, by the New York Police Department, also died via a self-inflicted gunshot wound after opening fire with an M4 rifle. Tamura shot multiple people in the lobby before taking the elevator to the 33rd floor, where he shot himself in the chest, N.Y.C. Police Commissioner Jessica S. Tisch said.
