Adams told reporters that investigators believe Shane Tamura of Las Vegas entered the building with the intent to reach the NFL 's offices but accessed the wrong set of elevator banks. "He seemed to have blamed the NFL ," Adams said. "The NFL headquarters was located in the building, and he mistakenly went up the wrong elevator bank."

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.
