Holy crap

“Surveillance shows a male exiting a black BMW carrying an M4 rifle in his right hand. The building security camera footage shows the shooter entering the lobby, turning right, and immediately opening fire at an NYPD officer. He then shoots a woman who took cover behind a pillar. He makes his way to the elevator bank, where he shoots a security guard who was taking cover behind the security desk. One additional male was shot in the lobby, per his own statement.
“The shooter then calls the elevator that opens in the lobby. A female exits the elevator, and he allows her to pass him unharmed. He goes up to the 33rd floor and begins to walk the floor, firing rounds as he travels. One person was struck and killed on that floor. He proceeds down the hallway and shoots himself in the chest,” she said.

So it sounds like she was the woman hiding behind a pillar, not whoever was targetted on the 33rd floor.

edit: and another article mentions he blamed the NFL for a brain injury. It looks like he was targetting the NFL’s headquarters but went to the wrong floor.
