The heart of New York City was shaken on Monday evening when a gunman, 27-year-old Shane Tamura from Las Vegas, opened fire in a skyscraper. He left behind a note claiming that the National Football League (NFL) was responsible for his brain injury, specifically Chronic Traumatic Encephalopathy (CTE), which is known to affect athletes.

Tamura, who had played football in high school, mistakenly entered the offices of Rudin Management instead of the NFL’s headquarters. He shot himself after the attack, which left four people dead, including New York City police officer Didarul Islam, who served as a security guard during the incident. An employee from financial firm Blackstone, Wesley LePatner, and two male civilians also lost their lives.

Several others were injured, including an NFL staff member. Mayor Eric Adams shared that Tamura seemed to have made the attack due to a “breakdown” related to his brain injury. After attacking in the lobby, Tamura ascended to the 33rd floor before turning the gun on himself. The horrifying scene brought parts of Midtown Manhattan to a standstill, as cops searched the building floor by floor to ensure everyone was safe. Witnesses described it as feeling like a “warzone”.

Nekeisha Lewis, who was near the shooting, recounted the terror of hearing gunfire and witnessing the chaos unfold. Although the city mourns the victims, it also sheds light on the troubling issue of gun violence.
