"There were no conversations or correspondence from Aaron to his family or legal team that would have indicated anything like this was possible", Baez said.
Family, friends, and members of Aaron Hernandez's legal team are still in shock, after the former New England Patriots player and convicted killer was found hanged in his prison cell Wednesday. At issue is whether Hernandez's violent behavior and mood swings could have been partly explained by chronic traumatic encephalopathy, a degenerative nerve disease found in the brains of those who have had repeated or severe hits to the head. Those affected are possibly more susceptible to committing suicide, doctors have found. It has been diagnosed in National Football League players, NHL players and professional wrestlers.
Baez said the family made arrangements for the Boston University CTE Unit to take possession of the brain, and the medical examiner's office agreed to those plans.
Aaron Hernandez's cause of death has been established following the former standout football player's demise in prison this week.
Baez said officials from the chief medical examiner's office told him they wanted to prepare the brain for study.

The Worcester County District Attorney Office has officially ruled Aaron Hernandez's death was a suicide.
Hernandez, 27, was serving a sentence of life without parole for the June 2013 murder of Odin Lloyd.
The disgraced athlete's daughter, 4-year-old Avielle Janelle Jenkins-Hernandez, was present at the trial and it was the last time he saw her before killing himself. "There would be no reason for them to withhold the brain".
There were also "three hand-written notes next to a bible" in Hernandez' cell. The verse, John 3:16, is one of the bible's most commonly recited.
Also, officials said, Hernandez tried to block his cell door from the inside by jamming it with several items preventing it from being opened.
Guards discovered the body of Hernandez hanging by a bedsheet from a cell window at a maximum security state prison not far from the Patriots' home stadium in Foxborough, Massachusetts.
