A judge has given the go-ahead for a fresh inquest into the death of a young soldier at Deepcut barracks 21 years ago.
Private Sean Benton, from Hastings, East Sussex, was found with five bullet wounds to his chest in June 1995 while undergoing training at the Surrey base.
Pte Benton's death was followed five months later by that of Pte Cheryl James, 18, who died from a single shot to the head. Pte Geoff Gray, 17, died from two bullet wounds to the head in September 2001, and in March 2002 the body of Pte James Collinson, 17, was found. He had died from a single gunshot wound.
All four deaths were investigated by the special investigation branch of the Royal Military Police, under the direction of Surrey Police, which found no evidence of foul play.
He said: "We have used some of the best shots in the British Army in my tests but none has been able to recreate the same pattern at the distances these suicides were supposed to have taken place. In the case of Sean Benton, the wounding pattern can only be achieved when fired at a range of 15 feet - that does not point to suicide."
Mr Swann added: "There is always the possibility that I may be wrong but I will believe that when someone can forensically prove that I am wrong otherwise I will stand by my findings."
Four young people's lives ended too soon. A cover up?
