Pinned by the Evidence - S9.E15

After a street fight took the life of a national wrestling champion, police had to determine if he was killed in cold blood, or in self-defense. A jury decided it was murder, and sentenced the accused to a minimum of twenty years in prison. Six years later, he was granted another trial; a forensic animator, who testified on his behalf, offered a different explanation for the most damning piece of evidence. [also marked as S9:E17]
