THE parents of a soldier who died at Deepcut Army barracks will meet senior police officers today to voice concerns over the investigation into his death.

Private Geoff Gray, 17, from County Durham, was one of four soldiers who died at the barracks between 1995 and 2002.

Their families do not believe they committed suicide by turning their own rifles on themselves, as Army investigations found.

Pte Gray's parents, Geoff and Diane, are dismayed at the way parts of the police investigation have been run.

They are particularly worried about the apparent involvement of Ministry of Defence officials in the independent inquiry.

Mr and Mrs Gray will meet Surrey Police Chief Constable Denis O'Connor and Deputy Chief Constable Robert Quick at their home in Hackney, east London, at 2.30pm.

Mr Gray, originally from Seaham, said they would discuss the MoD involvement and demand an apology for not being told about the part MoD officials played.

''We would hope that all the issues surrounding the MoD involvement in our son's case will be addressed,'' he said.

''At the conclusion of the meeting, we feel that no less than a public apology to all the families involved would suffice.

''Surrey Police said there would be no MoD involvement, that it would be totally independent.

"The MoD and the Army totally messed up the first investigation.''

''We feel that the whole investigation has been undermined by the involvement of the MoD police and the lack of willingness of Surrey Police to inform us of this.''

Pte Gray, Pte Sean Benton, 20, from Hastings, east Sussex, Pte James Collinson, 17, from Perth, and Pte Cheryl James, from Llangollen, north Wales, all died from gunshot wounds.

Surrey Police have spent a year re-examining the evidence along with an independent investigator, Frank Swann, hired by the families of the dead soldiers.

* On September 3, a police officer working on the inquiry into the deaths at Deepcut was taken off the investigation following an allegation of inappropriate behaviour.
