Gunman Blames NFL for Brain Injury, Kills Four in NYC Skyscraper Shooting

A 27-year-old shooter opened fire inside a Manhattan skyscraper on Monday night, killing four people and wounding others before killing himself in a horrific tragedy that shocked New York City. According to authorities, the assailant, a Las Vegas resident named Shane Tamura, seemed to be targeting the NFL because of a brain disorder he thought was brought on by playing football. But he made a mistake and ended up in the wrong office.

The NFL’s headquarters are located in a high-rise building in Midtown Manhattan at 345 Park Avenue, where the attack took place. According to reports, Tamura used an assault-style rifle to enter the building, fired in the lobby and then rode a lift to the 33rd floor. According to New York City Mayor Eric Adams, the shooter was likely aiming for the NFL offices, but he mistakenly went to a different floor occupied by Rudin Management, a real estate company that owns the building.

In a note he left behind, Tamura attributed his mental illness to chronic traumatic encephalopathy (CTE), a brain disorder associated with repeated head trauma. He allegedly wrote, “Please study my brain,” in the note. I apologize. He shot himself at the scene, and the note was discovered on his body. According to Mayor Adams, Tamura felt that playing football as a child had harmed his brain. However, former teammates and coaches have confirmed that Tamura only ever played in high school and never in the NFL.

Didarul Islam, a 36-year-old NYPD officer who was serving as a security guard in the building, was one of the four people killed in the shooting. A third child was on the way for Officer Islam, a father of two who had immigrated from Bangladesh. He is being praised as a hero for risking his life to keep others safe. “He died as he lived, a hero,” said Police Commissioner Jennifer Tisch.

Wesley LePatner, who worked for the international investment firm Blackstone, was another victim. Her company said in a statement that she was “brilliant, passionate, warm, generous, and deeply respected.” The identities of the other two male civilians who were slain have not yet been revealed. One of the injured was an NFL employee who is undergoing treatment for severe injuries. In a message to employees, NFL Commissioner Roger Goodell expressed his sadness and confirmed that one of his employees had been hurt in the attack.
According to reports, the shooter travelled from Las Vegas to New York by car before launching the attack. His motivation seems to be centred on his conviction that his mental decline was brought on by chronic traumatic encephalopathy, or CTE. CTE is a progressive brain disease commonly found in athletes who suffer repeated head trauma, especially in contact sports like football. Although professional athletes have been the subject of much of the research on CTE, lower-level athletes can also be affected.

Authorities responded quickly after shots were heard. The area around the building was placed on lockdown. Public transport was halted, and dozens of emergency vehicles rushed to the scene. Eyewitnesses described moments of panic. One woman, Nekeisha Lewis, who was dining nearby, told NBC News, “It felt like you were in a warzone almost.” She saw an injured man run from the building and said the entire experience was terrifying.

Police officers worked for hours, clearing the building floor-by-floor to ensure there were no further threats. A BBC journalist on the scene reported seeing a bloodied victim being taken away on a stretcher, and police urging people to seek shelter in nearby shops and buildings. President Donald Trump, who was visiting Scotland at the time, issued a statement calling the incident a “senseless act of violence” and promised that law enforcement agencies would “get to the bottom of it.”

Friends and former classmates of Tamura have expressed disbelief. One ex-teammate described him as a jokey, friendly person, while a former coach said he was a talented running back who had great promise in high school football. But something clearly went wrong in the years that followed. Investigators are still piecing together his background and mental health history to understand what led him to commit such a horrific act.

As the city mourns, tributes continue to pour in for the victims — especially Officer Islam, who is being remembered not only as a brave policeman but also as a devoted family man and a mentor in his community. Members of his mosque and neighborhood recalled his dedication to helping young men stay on the right path and his deep sense of duty.

This tragedy has raised serious questions, about gun control, mental health, and the long-term risks of contact sports. While CTE has mostly been associated with retired NFL players, Tamura’s case shows how even youth-level football can leave lasting psychological and neurological impacts, especially if left undiagnosed.

For now, New York City remains in shock, grieving for those who lost their lives, and searching for answers. The investigation continues as officials examine Tamura’s journey from Nevada, his mental state, and whether the attack could have been prevented. As the sun sets on Park Avenue, the city stands in sorrow, and in solidarity, with the victims and their families.
