Shane Tamura's CTE diagnosis linked to NFL shooting spree

In the United States, specifically New York City, Shane Tamura carried out a mass shooting on July 28, 2025, at the headquarters of the NFL. This tragic incident resulted in the deaths of four individuals, including a police officer, a security guard, and two employees of companies located within the building. Following the shooting, authorities discovered a note in Tamura's possession, in which he expressed his struggles with a traumatic brain injury and accused the NFL of concealing the dangers associated with brain injuries in football to prioritize profits over player safety. The severity of his mental health issues, including a diagnosis of Chronic Traumatic Encephalopathy (CTE), was confirmed by the New York City Office of the Chief Medical Examiner, which noted unambiguous evidence of low-stage CTE in his brain following his death from a self-inflicted gunshot wound. While Tamura had played high school football in California, he never reached the professional level, yet his grievances and mental health struggles highlight the ongoing concerns regarding brain injuries in contact sports. This shooting prompted discussions about the mental health implications for former athletes and the responsibilities of organizations like the NFL towards their players. Although the link between football and CTE had been acknowledged by the NFL in previous years, the impact of such a condition on individuals like Tamura continues to be a complex issue. The findings serve as a distressing reminder of the urgent need for transparency in sports regarding head injuries and their long-term consequences.
