A very interesting case where Jeremy Bamber was jailed for killing his mother,father, sister and her twin sons at a remote farm house. He blames his sister who was having some mental problems at the time. He has always maintained his innocence but few have believed him until this!! Bamber 'innocent' says lie test April 20, 2007 COMMENT ON THIS STORY CONVICTED mass murderer Jeremy Bamber took a lie detector test yesterday in a bid to prove his innocence and his lawyer said he passed. Bamber, 45, jailed in 1986 for killing his adoptive parents, his sister and her twin sons at the familys farmhouse, was hooked up to a polygraph in his cell. His lawyer Giovanni Di Stefano said Bamber was asked 12 questions, including if he had carried out the five killings and if he had paid a hitman to kill them. To both questions, he replied No and Mr Di Stefano said he passed the test conclusively. Expert Terry Mullins carried out the test thought to be the first of its kind in a British jail at Full Sutton prison, near York. Bamber maintains that his schizophrenic sister Sheila Caffell, a model dubbed Bambi, killed parents Neville and June, her six-year-old sons Nicholas and Daniel, and herself in Tolleshunt DArcy, Essex, in 1985. The case is currently before the Criminal Case Review Commission. A very interesting case!
