The release of the movie "Malcolm X" renewed interest in the controversial leader and most recent icon, but left many questions about the circumstances of the fiery orator's death. Part one of this special four-part series on Malcolm X digs deep into the series' archives to retrace 25-years of investigative reporting on Black America's most controversial leader. Through interviews, rare footage of the slain leader and readings of actual court transcripts of his killers' trial, host Tony Brown unveils several inconsistencies and examples of mysterious behavior. A never-before aired audiotape recording of the final minutes of Malcolm X's life -- up to the first shots that were fired -- is used for the first time.
