In fact, Hernandez left behind three suicide notes. One was addressed to the general public and the other two were written to specific people, TMZ:
Investigators found three hand-written notes next to a Bible in the cell. We're told one of the notes addressed the general public, and the other 2 were written to specific people.
Now that the cause and manner of death have been determined, officials say Hernandez's brain will be released to Boston University’s CTE Center as Mr. Hernandez’s family wishes.
The good news is Aaron allegedly killed people, including himself, because of CTE. That isn't official yet, but it will be once Boston University’s CTE Center finishes with his brain.
