The New York City office of the chief medical examiner said Friday that the brain of Shane Devon Tamura, the man identified as the gunman who killed four people at a midtown Manhattan office building that houses the NFL’s headquarters, had evidence of “low-stage CTE.”
Front Office Sports’ Amanda Christovich shared a release from the NYC medical examiner’s office on X.
The medical examiner examined Tamura’s brain during his autopsy after investigators said he left a note blaming football for his mental health struggles and requesting it be studied for CTE. Authorities said Tamura carried out the July 28 attack at the Park Avenue building that houses NFL headquarters.
“Terry Long football gave me CTE and it caused me to drink a gallon of antifreeze,” the shooter wrote, according to law enforcement. “You can’t go against the NFL, they’ll squash you.”
Terry Long, a former football player for the Pittsburgh Steelers, was diagnosed with CTE. He died by suicide in 2005.
“Study my brain please I’m sorry Tell Rick I’m sorry for everything,” the note added.
