A report into the death of a 22-year-old woman in 1975 claims a British soldier deliberately shot her and lied to cover up his actions.
Northern Ireland's Historical Enquiries Team was investigating the death of Bernadette Friel, a Catholic who was shot in the head in in a house in Derry on 19 October 1975.
The mother of one died in hospital two days later.
The HET claims the soldier, Thomas Ramsay, deliberately shot Ms Friel then lied repeatedly to cover up his responsibility.
He was jailed for a year for her manslaughter after he claimed she had been shot during a game of Russian roulette.
Following the publication of the report, Ms Friel's family said they were pleased with its findings.
However, they said it raised 'serious questions' about the impartiality of the Director of Public Prosecutions.
