New York, NY – A deadly shooting at the National Football League’s headquarters in Manhattan left four people dead and one seriously injured Monday evening, in what authorities are calling the city’s worst gun violence incident in decades.
According to law enforcement sources cited by CNN and ABC News, the gunman, identified as 27-year-old Shane Devon Tamura, opened fire at 345 Park Avenue during rush hour before fatally shooting himself. Police discovered a multi-page note in Tamura’s possession referencing chronic traumatic encephalopathy (CTE), a brain condition linked to repeated head trauma, and grievances allegedly directed toward the NFL.
Tamura, who reportedly drove from Las Vegas to New York prior to the shooting, wrote in the note: “Study my brain please. I’m sorry.” Additional pages accused the NFL of allegedly concealing the dangers of football-related brain injuries to preserve profits. Authorities confirmed Tamura had played high school football in Los Angeles but had no professional ties to the NFL.
Among the victims was Officer Didarul Islam, 36, who was fatally shot while responding to the attack. According to ABC News, Islam, a father of two with a third child on the way, was praised for acting quickly to protect civilians. One civilian—an NFL employee—was critically injured and remains hospitalized in stable condition.
In a statement shared with staff, NFL Commissioner Roger Goodell confirmed the injury, reassured employees about safety, and noted a heightened security presence in the coming days. Employees based in New York were advised to work remotely Tuesday.
Authorities continue to investigate Tamura’s motive and background. As of Tuesday morning, no official connection between Tamura and the NFL has been identified beyond his expressed grievances.
