A second inquest begins today into the death of two Sydney nurses in Queensland's Lockyer Valley, west of Brisbane, nearly 40 years ago.
Three men identified as "persons of interest" are expected to be called to give evidence at the inquest into the deaths of Lorraine Wilson and Wendy Evans.
The women's remains were found in bushland at Murphys Creek in the Toowoomba ranges in 1976.
They had gone missing two years earlier trying to hitchhike from Brisbane to Goondiwindi.
An inquest was held in 1985 but no charges were laid.
Attorney-General Jarrod Bleijie ordered another inquest after the family of Lorraine Wilson wrote to him last year.
Mr Bleijie says more evidence and witnesses has been uncovered through ongoing police investigations and Crime and Misconduct Commission (CMC) hearings in 2010.
A pre-inquest hearing has identified seven people of interest, but four have since died.
The remaining three men are expected to appear before the inquest, which will held over the next week in Toowoomba before Queensland coroner Michael Barnes.
