The science of finding buried bodies

Ian Brady, who tortured and killed five children in the UK in the 1960s with his accomplice Myra Hindley, died in prison on May 15. Jailed in 1966, Brady buried four of his victims in shallow graves on Saddleworth Moor outside Manchester – and the remains have since been found. Sadly, the body of one his victims, Keith Bennett, however, is still missing.
