A man who gunned down four people then killed himself in a Manhattan skyscraper may have targeted the American football league because he blamed it for brain injuries he claimed he suffered, Mayor Eric Adams said on Tuesday, July 29.
Information that the killer carried in a note referring to the degenerative brain disease CTE offered a possible motive for the Monday shootings at offices used by the National Football League, among others.
A source confirmed that in a three-page handwritten note found in the gunman's wallet, he wrote, "Chronic traumatic encephalopathy (CTE). Study my brain please. I'm sorry." "Football gave me CTE and it cause me to drink a gallon of antifreeze. You can't go against the NFL. They'll squash you."
The suspected shooter, identified as 27-year-old Shane Tamura, went on to ask that his brain be studied for CTE, and alleged that the league "knowingly concealed the dangers to our brains to maximize profits."
