The man who killed four people in the New York City skyscraper that is home to NFL headquarters carried a note blaming the league for his mental health problems.

Shane Devon Tamura, who killed at least four people in N.Y.C. before turning the gun on himself, claimed in his suicide note that he had brain disease CTE

Meiko Locksley, one of 152 athletes diagnosed with CTE before even reaching the age of 30 as part of the Boston University CTE Center’s 2023 study, never made it past college football and began exhibiting signs of the disease in his 20s.
