Blackstone Staff Return to Park Avenue a Week After Tragedy

Blackstone Inc.’s Steve Schwarzman walked into the company’s headquarters at 345 Park Ave., through the lobby that a week ago had been the scene of horror and chaos when a gunman killed one of its rising stars and put scores of employees in lockdown.

Michael Chae, the firm’s chief financial officer, came through too, stopping to shake hands with three staff stationed outside the door, and then inside had a huddle with Bill Rudin, whose family owns the Midtown skyscraper and also lost an employee last Monday. Schwarzman, Blackstone’s chief executive, and firm President Jon Gray also stood in the lobby, greeting people as they walked in.
