NYC Shooter Kills 4, Leaves Note Claiming CTE, Criticizing NFL

Shane Tamura, the gunman who killed four people in a Midtown Manhattan office tower, left a three-page suicide note claiming he suffered from chronic traumatic encephalopathy (CTE), a brain disease linked to repeated head trauma in contact sports like football. Tamura's note accused the National Football League (NFL), which has offices in the building where the shooting occurred, of concealing the dangers of the sport for profit. The note referenced former NFL player Terry Long, who died by suicide in 2005 after being diagnosed with CTE and drinking antifreeze, and implored authorities to study Tamura's brain. Tamura shot himself in the chest after the attack, and police have noted he had a history of mental illness. The shooting left four dead, including a New York police officer, and one person critically injured. Investigations into Tamura's motives continue as the community grapples with the implications of CTE and its ties to violence and mental health.
