Mass Shooting at NFL Headquarters
On July 28, Shane Tamura carried out a mass shooting at 345 Park Avenue in New York City, targeting the NFL headquarters.
“A three-page note found on Tamura revealed he claimed to suffer from traumatic brain injury.”
Tamura, a 27-year-old former high school football player from Las Vegas, killed four people, including a police officer, a security guard, and two office workers, before dying by suicide.

The victims were identified as Aland Etienne, Wesley LePatner, Didarul Islam, and Julia Hyman.
Tamura left behind a three-page note in which he claimed to suffer from traumatic brain injury and blamed the NFL for concealing the dangers of brain injuries related to football.
The New York City Office of the Chief Medical Examiner later confirmed that Tamura had low-stage Chronic Traumatic Encephalopathy (CTE), a degenerative brain disease linked to repeated head trauma.
CTE and Behavioral Impact
The confirmation of CTE in Tamura's brain has sparked discussions about the potential link between the disease and violent behavior.
CTE is a progressive brain disease caused by repeated head trauma, often found in athletes involved in contact sports.
The medical examiner noted that while Tamura had low-stage CTE, it is currently impossible to determine what role, if any, the condition played in his actions.
This uncertainty highlights the ongoing research into CTE and its effects on mental health, as emphasized by various experts and organizations.
CTE and NFL Responsibility
Tamura's suicide note referenced a documentary on CTE and urged others to study his brain.
“Authorities said he targeted the NFL, blaming the league and football for his struggles with the neurodegenerative disease.”
He believed his mental health issues were linked to his history of playing high school football.
The NFL has acknowledged the connection between football and CTE since 2016.
The league expressed condolences to the victims' families but condemned the violent act.
The NFL emphasized that the science around CTE is still evolving and does not justify the crime.
This incident has reignited debates about the NFL's responsibility in addressing brain injuries among players.
It has also raised broader concerns about the implications for contact sports in general.
CTE Impact Beyond Athletes
The case of Shane Tamura has drawn attention to the broader issue of CTE and its impact on individuals beyond professional athletes.
While CTE is commonly diagnosed posthumously in former NFL players, it is also found in student athletes and military personnel.

This has led to increased scrutiny of contact sports and the need for more comprehensive safety measures and research.
Experts argue that understanding the full impact of CTE requires further study, particularly in younger athletes who may be at risk of developing the disease from a young age.
