A coroner's ruling into the death in Wiltshire of Anne-Marie Ellement, a soldier who said she had been raped and bullied, has been unexpectedly delayed today.
It comes after lawyers for the military revealed they had uncovered new documents, including a reference to a diary and mobile phones Corporal Ellement's family say were never passed to them.
Lawyers for the family of Royal Military policewoman, who was found hanging at her barracks in Bulford in October 2011, have accused the military police of a gross breach of guidelines on evidence disclosure.
Detective Inspector Iwan Jones told a pre-inquest review hearing in Aberdare Coroner's Court the scale of investigation had widened:
Having reviewed some of the evidence we have decided to expand the investigation. We aiming to have statements from a substantial number of soldiers - between 94 and 96 - emergency service personnel and members of the public.
We are still waiting for (all of the) soldiers accounts from the army at this moment in time. There have been logistical problems as some of these are now serving abroad."
Police investigating the deaths of three soldiers, including one from Bath, who died during an SAS selection programme in the Brecon Beacons say they have not yet interviewed everyone they would like to.
Army reservists Edward John Maher, 31, Craig John Roberts, 24, and 31-year-old James Dunsby (from Bath) died while taking part in a gruelling SAS selection exercise on one of the hottest days of the year. A number of other soldiers also collapsed and needed medical attention.
It is thought the group were carrying out an exercise known as the "Fan Dance", which involves marching up 886-metre high Pen Y Fan mountain and down the other side carrying a weighted pack and rifle, then doing the route in reverse, in a set time.
An inquest has heard how a soldier from Bath, who died following an SAS training exercise, suffered multiple organ failure.
Corporal James Dunsby, was pronounced dead in hospital 17 days after collapsing in the Brecon Beacons on South Wales's highest mountain, Pen Y Fan, on one of the hottest days of the year. Fellow reservists Edward John Maher and Craig John Roberts also died in the incident.
