Moors murderers Myra Hindley and Ian Brady tortured and murdered five children in and around Manchester between 1963 and 1965.
But Brady remains were disposed of in Merseyside, somewhere off the coast.
Channel 4's Moors Murders documentary, which aired this week and is available online, told the story of the killer pair, whose murder spree only ended when Hindley's brother-in-law, David Smith, reported them to the police after witnessing their final murder.
