New York City Shooter
Takes His Own Life to Ensure Brain Examination
Published July 29, 2025 6:19 AM PDT
The individual responsible for the shooting at the NFL headquarters in New York City tragically ended his life by inflicting a gunshot wound to his chest. This act appears to have been a deliberate choice, as he sought to have his brain preserved for examination, possibly to highlight the effects of his mental health struggles.
Authorities discovered a three-page suicide note on the body of 27-year-old Shane Tamura, which detailed his belief that he had been suffering from CTE (Chronic Traumatic Encephalopathy). This degenerative brain disease is typically linked to individuals who have experienced repeated head injuries, a condition that is increasingly being studied within the context of athletes, as noted by the Mayo Clinic.
The investigation revealed that Tamura’s intention behind his drastic actions was to ensure that his brain would be analyzed in order to understand the potential impacts of CTE and other mental health challenges he may have faced.

In his suicide note, Tamura made references to the NFL, indicating his grievances against the organization. New York City Mayor Eric Adams later revealed that Tamura had targeted the NFL headquarters but mistakenly took the wrong elevator, which adds a layer of complexity to the situation.
The NFL corporate headquarters is located at 345 Park Avenue in New York City. Following the tragic events, NFL Commissioner Roger Goodell confirmed that one employee suffered serious injuries as a result of the shooting, highlighting the urgent need for safety measures in workplaces.
Currently, it remains unclear whether Tamura had an official diagnosis of CTE. He had a history of playing youth football, a sport notoriously associated with the risk of developing chronic neurological conditions due to cumulative brain injuries sustained during play.
It is confirmed through various sources that Tamura struggled with mental health issues, which raises significant concerns regarding the psychological support available for individuals facing similar challenges.
Shane Tamura participated in high school football during his time in Southern California, specifically in schools located in the Los Angeles area, graduating in 2016. His involvement in football raises questions about the long-term effects of sports on mental health and brain health.
Over the weekend, the Las Vegas resident made a cross-country journey to New York City, where he ultimately executed the tragic shooting inside a prominent skyscraper on Monday night, raising questions about his motives and state of mind leading up to the event.
In this shocking incident, Tamura took the lives of four innocent individuals, including a dedicated NYPD officer who was a father to two children and had a baby on the way. Additionally, one victim remains in critical condition, emphasizing the devastating impact of this tragic event on families and the community.
The full motive behind Tamura’s actions is still under thorough investigation by law enforcement agencies. In light of this tragic event, it has been reported that additional security measures will be implemented at the building to ensure the safety of employees and visitors alike.
