A gunman who killed four people in a New York skyscraper was attempting to attack the NFL headquarters but mistakenly took the wrong elevator, according to New York City Mayor Eric Adams.
The attacker, identified as 27-year-old Shane Tamura from Las Vegas, entered 345 Park Avenue—home to several high-profile firms including the NFL, Blackstone, and KPMG—on Monday evening with an M4 rifle.
Mayor Adams told MSNBC: “We have reason to believe he was focused on the NFL agency located in the building, but he entered the wrong elevator.”
Among the victims was NYPD officer Didarul Islam, 36, who was married with two children and a third on the way. Also killed was Blackstone Senior Managing Director Wesley LePatner. The investment firm described her as “brilliant, passionate, and deeply respected.” A female NFL staffer was seriously injured and remains in hospital.
According to authorities, Tamura had a documented history of mental illness and left a note expressing frustration about his mental health issues being linked to his high school football background. Investigators suspect he believed he had chronic traumatic encephalopathy (CTE), a brain condition associated with repeated head trauma.
CCTV footage showed Tamura arriving in a black BMW just before 6:30 p.m., entering the lobby, and opening fire. After fatally shooting multiple people, including a security guard, he ascended to the 33rd floor where he killed another victim before turning the weapon on himself.
The tragic event has raised questions about building security, mental health intervention, and the impact of contact sports on long-term brain health.
