FILE - In this Friday, April 14, 2017 file photo, Former New England Patriots tight end Aaron Hernandez turns to look in the direction of the jury as he reacts to his double murder acquittal in the 2012 deaths of Daniel de Abreu and Safiro Furtado, at Suffolk Superior Court in Boston. Dr. Ann McKee of the CTE Center at Boston University presented the findings of her examination of Hernandez's brain on Thursday, Nov. 9. McKee says she could not say that Hernandez's behavior was a result of his severe case of chronic traumatic encephalopathy. But she says Hernandez suffered substantial damage to several important parts of the brain, including the frontal lobe. Hernandez killed himself in April, while serving life in prison for murder.
