New York City Mayor Eric Adams says that a gunman who killed four people at a Manhattan office building was trying to target the headquarters of the National Football League but took the wrong elevator.

In a press conference, New York City Mayor Eric Adams identified the slain police officer as 36-year-old Didarul Islam, who had been working with the New York City Police Department for three and a half years. One person who was wounded during the shooting remained in critical condition, Adams said.

The shooter behind a deadly rampage inside an office building in Midtown Manhattan on Monday evening was apparently targeting NFL offices there, New York City Mayor Eric Adams said Tuesday morning.Law enforcement sources say investigators recovered a three-page rambling note from gunman Shane Tamura's wallet in which he referenced the brain disease CTE.
