NEW YORK (AP) — A man with a rifle killed an off-duty New York City police officer and three other people before taking his own life at a Manhattan office tower on Monday, according to officials.
Law enforcement officials were working to unravel what took place and why this location may have been targeted in a city that had recently announced it was on pace to have its fewest people hurt by gunfire than any year in recent decades.
Here are some things to know:
What happened?
A man exited a double parked BMW with an M4 rifle and then walked toward the building on Monday evening, according to surveillance video.

He quickly opened fire on the NYPD officer as he entered the building before shooting a woman who tried to take cover, police Commissioner Jessica Tisch said at a news conference on Monday night. He then started “spraying†the lobby with gunfire.
The man went to the elevator bank and shot a security guard who was taking cover behind a security desk and also another man in the lobby, Tisch said.
The man took the elevator to the 33rd floor to a real estate management company and one person was shot and killed on that floor. The man then walked down a hallway and shot himself, she said.
What do we know about the gunman?
Police identified Shane Tamura of Las Vegas as the gunman, although his motive and reasoning for targeting the building was not immediately clear.
Tamura had a “documented mental health history,†Tisch said.
His vehicle had traveled across the U.S. through Colorado on July 26 and then Nebraska and Iowa on July 27. It arrived in Columbia, New Jersey, as recently as Monday afternoon, before making it to New York City, she said.
Officers found a rifle case, a revolver, magazines and ammunition in his car, Tisch said.

No one answered the door at the address listed for Tamura in Las Vegas.
Who were the victims?
Didarul Islam, 36, had served as a police officer in New York City for 3 1/2 years. He was an immigrant from Bangladesh.
Islam was married and had two young boys, Tisch said. His wife is pregnant with their third child.
The names of the other victims, along with a man who was seriously wounded and remains in critical condition, have not yet been released.
Where did the shooting happen?
The shooting took place at 345 Park Avenue, a commercial office building in a busy area of midtown that is just a short walk north from Grand Central Terminal and about a block east of St. Patrick’s Cathedral.
The building houses offices for companies including the NFL and real estate company Rudin, as well as finance companies KPMG and Blackstone. It also includes the consulate general of Ireland.
