In the early hours of 7 August 1985, five members of the Bamber family were shot dead with a .22-calibre Anschutz rifle, but who killed them?Initially, Sheila Bamber was thought to have killed her twin six-year-old sons and adoptive parents and then to have turned the gun on herself. But a year later, Jeremy Bamber, also adopted, was convicted. He continues to protest his innocence. Sheila Bamber, who was known to have struggled with mental-health issues, was at first thought to have murdered her twin sons and adoptive parents and then to have turned the gun on herself. Forensic evidence, however, told a different story and raised such questions as how Sheila could have shot herself twice in committing suicide. A year later it was Jeremy Bamber, the only survivor, who was convicted of the callous murders of his entire family. He is currently serving a life sentence, but continues to protest his innocence. In this the first full account of the case, Roger Wilkes bases his story around specially commissioned forensic research, personal interviews with Jeremy Bamber and previously undisclosed accounts and witness statements. Extraordinary and shocking, it is a story that would defy the imagination of fiction writers.
