Lawyer says Aaron Hernandez had advanced stages of CTE

A study of Aaron Hernandez's brain showed he had stage 3 CTE when he killed himself in April, researchers said Thursday.

CTE, which can be diagnosed only in an autopsy, has been found in former members of the military, football players, boxers and others who have been subjected to repeated head trauma. A recent study found signs of the disease in 110 of 111 NFL players whose brains were inspected.
