Shane Devon Tamura, the 27-year-old gunman behind Monday’s shooting at the NFL headquarters in New York City, left behind a chilling suicide note blaming chronic traumatic encephalopathy (CTE) for his actions. The former football player from Las Vegas fatally shot himself during a tense standoff after opening fire inside a Manhattan skyscraper housing the league’s offices.

According to CNN, the suicide note read: "Terry Long football gave me CTE, and it caused me to drink a gallon of antifreeze. You can't go against the NFL; they'll squash you. Study my brain, please. I'm sorry. Tell Rick I'm sorry for everything." The message, handwritten over three pages, was later recovered by investigators.

Terry Long, a former Pittsburgh Steelers player referenced in the note, was diagnosed with CTE and died by suicide in 2005 after ingesting antifreeze. CTE is a degenerative brain condition often found in athletes exposed to repeated head trauma. Tamura had played competitive football in his youth and reportedly believed he was suffering from the disorder.
