White House Farm killer Jeremy Bamber is hoping to have his whole life sentence overturned over what his legal team is new evidence.
Bamber, now 61, was convicted of shooting dead his adoptive parents Nevill and June, his sister Sheila Caffell, 26 and her six-year-old twin sons Daniel and Nicholas in August 1985 in Tolleshunt D'Arcy, Essex.
Lawyers acting on his behalf have submitted fresh evidence to the Criminal Cases Review Commission which they claim sheds new light on the murders.
