Quincy, M.E. - Season 3 Episode 2 A Blow to the Head ... a Blow to the Heart

After a championship bout a young boxer collapses and dies. His wife thinks that it wasn't an accident and asks Quincy, a friend of her husband's trainer and the coroner on call, to see if he can find out how he really died. Once Quincy has completed the autopsy he begins to wonder if the woman is right, there is certainly something that does not seem to be quite right with the death, something that is made even more certain when Quincy is approached by 4 thugs who tell him in no uncertain terms that he better hurry up and make his report.
