Shane Tamura, Who Killed 4, Targeted NFL at New York Office Tower Had ‘Unambiguous’ CTE, Medical Examiner Confirms

Shane Tamura, the man responsible for a mass shooting at a New York City office tower that took the lives of four individuals, has been confirmed to have had chronic traumatic encephalopathy (CTE) – a brain disease often associated with football. The tragic incident occurred on July 28 at 345 Park Avenue in midtown Manhattan, where Tamura, armed with a semi-automatic rifle, fatally shot four people, including an off-duty police officer, before taking his own life. The building, where the shooting unfolded, is also home to the National Football League’s headquarters.

According to the New York City medical examiner’s office, a note was found that Tamura penned, expressing his belief that he was suffering from CTE and directed that his brain should be studied after his death. The revealing note highlighted his concerns about the impact of the disease and referenced the NFL in a critical manner. It was later disclosed that Tamura, a former high school football player, had left the note prior to his suicide.

Following the shooting, Mayor Eric Adams of New York revealed that Tamura’s intended target was believed to be the NFL offices within the building, though he had mistakenly taken the wrong elevator. The tragic event sparked an investigation into Tamura’s motives and mental state, leading to the revelation of his suspected brain condition. The release of the medical examiner’s findings shed light on the link between CTE and behavioural changes, particularly in individuals exposed to repetitive head trauma, such as athletes in contact sports like football.

Chronic Traumatic Encephalopathy, a progressive degenerative brain condition, can only be definitively diagnosed posthumously through a neuropathological examination. The disease has been a subject of significant concern within the sporting world, especially in contact sports where head injuries are prevalent. The prevalence of CTE among former NFL players has raised awareness about the long-term consequences of such injuries and their impact on individuals’ mental health and behaviour.

In a statement released by the New York City Office of Chief Medical Examiner, the presence of low-stage CTE was confirmed in Tamura’s brain tissue. This diagnosis aligned with the distinctive behavioural changes associated with the disease and provided insights into the potential factors contributing to Tamura’s violent actions. The case serves as a poignant reminder of the complex interplay between mental health, brain injuries, and societal factors in cases of extreme violence.

The tragedy involving Shane Tamura underscores the ongoing dialogue surrounding mental health awareness, the impact of sports-related injuries, and the urgent need for support systems for individuals grappling with such challenges. The intersection of CTE, sports culture, and mental well-being continues to be a focal point for research and advocacy efforts aimed at preventing similar incidents in the future. As discussions on mental health and brain injuries evolve, initiatives promoting early detection, intervention, and support are crucial in safeguarding the well-being of individuals in various spheres of life.
