Jeremy Bamber has been behind bars for more than 26 years for shooting his wealthy adopted parents, June and Nevill, his sister Sheila Caffell and her six-year-old twin sons Daniel and Nicholas at their Essex farmhouse in Tolleshunt D'Arcy between Maldon and Colchester.
The 52-year-old was given a whole-life tariff after being convicted of the murders in October 1986 but he has always protested his innocence and claims his schizophrenic sister Ms Caffell shot her family before turning the gun on herself in a remote Essex farmhouse.
In 2009, Bamber lost a Court of Appeal challenge against the order that he must die behind bars. He has twice lost appeals against conviction.
The Criminal Cases Review Commission reached a provisional decision not to refer his case back to the Court of Appeal in February last year despite claims by his legal team that they had new evidence that could overturn his conviction.
