New York Gunman Kills Four, Targets NFL Headquarters

On July 28, 2025, Shane Devon Tamura, a 27-year-old man with a history of mental illness, carried out a mass shooting at 345 Park Avenue in Manhattan, targeting the National Football League (NFL) headquarters but mistakenly taking the wrong elevator. Tamura opened fire in the building's lobby and on the 33rd floor, killing four people including an off-duty NYPD officer, a real estate executive from Blackstone, and an NFL employee, before turning the gun on himself. Authorities found a suicide note in which Tamura claimed to suffer from chronic traumatic encephalopathy (CTE), attributing it as a motive for his attack, although he never played in the NFL. New York City Mayor Eric Adams confirmed that Tamura intended to target the NFL offices but accidentally entered the wrong part of the building, leading to additional casualties among employees in other firms. The incident prompted NFL Commissioner Roger Goodell to assure the safety of other NFL employees and honor the slain officer, while New York City officials ordered flags to be lowered to half-staff in memory of the victims. President Donald Trump expressed condolences and confidence in law enforcement's efforts to investigate the senseless act of violence.
