That's not much of a "bottom line" when one M.E. rules that Martin died of natural causes and that the beating he took had nothing to do with it. For my two cents, that doc put his reputation on the line to cover up the circumstances of Martin's death, and he lost. The other M.E. ruled ruled that it was suffocation from upper respiratory blockage due to ammonia inhalation. Now, that could not be missed by a real autopsy.
Natural causes vs. a highly unnatural death for a teen. One of the docs used an official autopsy report to shield a crime by law enforcement officials. There's your true bottom line.
Maybe it is just business as usual in those parts.
