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. Adams said investigators recovered a three-page rambling note from gunman Shane Tamura's wallet in which he referenced the brain disease CTE.

Mayor Eric Adams on X: "Tonight, our city is reeling and four innocent families are mourning, including the family of NYPD Officer Didarul Islam, who was killed at 345 Park Avenue. He represented the best of New York City, an immigrant from Bangladesh who put on a uniform to protect and serve us all."
