A 19-year-old man has been arrested and charged with murdering two young women in South Australia's mid-north.
The teenager, of Quorn, will appear in court on the double murder charge on Thursday after police made the arrest late on Wednesday evening.
He is accused of killing 22-year-old Jasinta-Leigh Fullerton, a well-known outback identity who rode camels in bush races, as well as a 16-year-old girl, who was reported missing by her parents.
Detectives will excavate a grave site at first light on Thursday.
Ms Fullerton was found dead on Groves Road at Quorn at about 3.45am (CDT) on Wednesday, not far from where she lived and only hours after she was known to have left a local hotel.
Detective-Superintendent Grant Moyle said it was evident from the scene that Ms Fullerton had been murdered and her death would devastate the local community.
'There will be a considerable police presence in this area during this investigation,' he told reporters prior to the arrest.
The 16-year-old victim had lived in Port Pirie and was reported missing on Tuesday evening.
The accused teenager will appear in Port Augusta Magistrates Court.
