Conspiracy - Season 1 Episode 4 The Lord Lucan Dossier

The case of John Bingham, 7th Earl of Lucan, who disappeared in November 1974, coinciding with the murder of his children's nanny Sandra Rivett. Lucan was never caught or tried for the crime, but in the four decades since he fled numerous sightings have been reported of him from around the world. Some people believe he escaped justice, while others think he too was later murdered. Other cases considered include the kidnapping and murder of aviator Charles Lindbergh's baby son in 1927 and the disappearance of American union leader Jimmy Hoffa in an act some people claim was a mob-sanctioned hit
