Shooter Cites CTE in Deadly NYC Skyscraper Attack
30 Jul
Summary
- Shooter left note claiming he had CTE, a brain disease linked to football
- Shooter targeted NFL headquarters but took wrong lift
- CTE can only be diagnosed after death, but symptoms include aggression and violence

In a tragic incident, a 27-year-old man, Shane Tamura, opened fire inside a New York City skyscraper, killing four people. Tamura left a note claiming he had CTE, a degenerative brain condition caused by repeated head trauma, which has been linked to violent behavior.
According to the note, Tamura believed he was targeting the headquarters of the NFL, but he took the wrong lift and ended up in a different building. In his three-page note, written in various inks, Tamura repeatedly asked for his brain to be studied for CTE, a condition that can only be diagnosed after death.
The article explores the potential link between CTE and violent crime, citing cases like former NFL player Kellen Winslow, who argued for a reduced sentence for multiple rapes due to head trauma, and former San Francisco 49ers star Phillip Adams, who shot and killed six people before taking his own life in 2021. Experts say the symptoms of CTE, including aggression, paranoia, and impulse control problems, could contribute to such acts of violence.
Tamura, who had a successful high school football career, seemed to harbor animosity towards the NFL, writing in his note that the league "knowingly concealed the dangers to our brains to maximize profits." The article also mentions the NFL's efforts to fund CTE-related research and provide mental health support, as well as the ongoing debate around the sport's safety measures.
