(NewsNation) — The fourth victim in Monday’s shooting at a Manhattan office building has been identified as Julia Hyman.
Hyman, 27, worked for Rudin Management after graduating from Cornell University’s Peter and Stephanie Nolan School of Hotel Management.
Blackstone executive Wesley LePatner, NYPD Officer Didarul Islam, and security guard Aland Etienne were also killed in the attack near East 52 Street between Park and Lexington avenues.
Police started getting calls at 6:28 p.m. about an active shooter inside 345 Park Avenue.
The gunman, identified as Shane Tamura, 27, was seen on surveillance video getting out of a black BMW with a rifle in his hand. He walked into the 44-story building and immediately shot an officer, the NYPD said.
Tamura shot a woman who was trying to hide behind a pillar and kept firing, spraying bullets across the lobby. He walked toward the elevators and shot a guard behind the security desk. Another man was shot in the lobby but survived.
Tamura let a woman walk out of an elevator and into the lobby without injuring her. He then went up to the 33rd floor, Rudin Management’s office, and fired rounds as he walked through the room, killing another person on that floor.
He then went down a hallway and fatally shot himself in the chest, NYPD said.
“Pure evil came to the heart of our city and struck innocent people, and one of our police officers who was protecting those people,” Patrick Hendry, president of the Police Benevolent Association of the City of New York, said at a news conference.
“We lost four people tonight, and our hero brother who gave his life for this city.”

The building he attacked houses financial firms and the National Football League, among other companies.
The NYPD is leading the investigation with help from the Federal Bureau of Investigation.
