The "Detective of Death."

Medical examiner Michael M. Baden. In his new book, Unnatural Death: Confessions of a Medical Examiner, Baden, the former chief medical examiner for New York City, reviews the record of famous autopsies of the last 30 years as evidence of a pattern of bungled investigations of unnatural deaths. Baden, who has been a medical examiner for 30 years, views his profession as a historian or anthropologist who revisits ruined or questionable autopsies in the hopes of correcting history. Baden is now director of the forensic sciences unit for the New York State Police.

Louisiana State medical examiner Louis Cataldie was the coroner for the East Baton Rouge Parish in Louisiana from 1998 to 2003. When Hurricane Katrina hit, Dr. Cataldie helped to evacuate patients and set up field hospitals. He also aided the injured and investigated deaths.

At 98, Carter is the oldest living president in U.S. history. After serving his term, he worked to promote safe housing, human rights and conflict resolution. Originally broadcast in '93, '95 and '96.
