Synopsis: In this all-new edition of Autopsy, the hugely popular HBO documentary series, former NYC forensic examiner Dr. Michael Baden digs his scalpel into his highest-profile case - five grisly-good, landmark homicide investigations. With graphic, never-before-seen footage and detailed forensic explanations, Dr. Baden takes you through cases that span nearly a century, dating back to the mysterious disappearance of the royal Romanov family in Russia in 1918; the notorious deaths of Sid Vicious and his girlfriend Nancy four months apart in 1978-9; the shocking double-murder case involving O.J. Simpson in 1994; and the recent spate of illnesses and deaths due to exposure to toxic chemicals by first responders at Ground Zero in the hours and days after 9/11.
