Gertrude Canning from County Donegal was just 20 years old when she was shot several times and her body was dumped in a field close to the Scottish army base where she worked.
On a bright, sunny day in June 1942 Gertrude Canning, dressed smartly in her Women’s Royal Naval Service (WRNS) uniform, made her way to Inveraray in Scotland to post a letter to her family in Lifford.
Five days later her body was found in a hedge by children, not far from the base where she worked.
Her killer was never caught but her nephew Liam Canning said he knows the identity of the serviceman suspected of the murder.
“From what has been presented to the family, I could clearly identify who I think is the suspect,” he told BBC Radio Foyle today.
“Police in Scotland have said that if the case were to come before them now they would solve it.
“The family are not looking for revenge. We have no real malice towards the person that did this.
“When we started this, the primary goal was not about finding a killer, it was about showing respect 70 years on for our aunt,” said Mr Canning.
In June, family members will travel to Inverary where they will unveil a plaque in memory of the murdered WRN.
