Hernandez was found guilty of murder in 2015, for the death of Odin Lloyd, who was dating the sister of Hernandez's fiance.

Dr. Ann McKee says she can't say whether the CTE contributed to Hernandez's crime, but she does say that his frontal lobe, which is responsible for decision making, judgement, and cognition was damaged.
