Earlier this year, Aaron Hernandez  decided to abruptly take his own life in his jail cell, just days after being found not guilty of the 2012 double-homicide. It was a shocking turn of events, to say the least.

Months after the fact, a report released by his attorney says the former New England Patriots tight end’s brain showed severe signs of CTE—the likes of which are only seen in players around the age of 67-years-old.

In a news conference at his offices, attorney Jose Baez says testing showed that Hernandez had a severe case of the disease. Baez said the CTE was at Stage 3, with Stage 4 being the highest.

Baez also said a federal lawsuit against the NFL and the New England Patriots on behalf of Hernandez’s daughter was filed this afternoon.

Jenkins-Hernandez is claiming that both the league and his team properly informed Hernandez as to his health status.

Unfortunately for athletes, CTE can only be diagnosed in an autopsy and there are no known cures as of right now.
