One NYPD officer and at least four civilians are confirmed dead after gunman opened fire in office building.
A Blackstone employee who was on their way to the lobby of the building to pick up food on Monday evening fled to safety after getting an alert from DoorDash.
The employee, who was working late, was heading down to the lobby when the delivery driver messaged her that there was a shooter in the lobby, according to The Wall Street Journal. The employee immediately rushed into a mother’s room with several other colleagues to take shelter as the harrowing scene unfolded in the lobby of 345 Park Avenue.
