A State Emergency Service volunteer has admitted murdering a woman and a girl whose body was found in a shallow grave at a South Australian cemetery.
Jose Enzo Omonte-Extrada, 20, pleaded guilty on Tuesday to murdering Jasinta-Leigh (Jessie) Fullerton, 22, from Quorn, and Rebecca Elizabeth Wild, 16, from Port Pirie, last December.
He appeared via video link in Port Augusta Magistrates Court.
The body of Ms Fullerton, a well-known outback identity who rode camels in bush races, was found early on December 5 last year next to her ute, less than 100 metres from her grandparents' home in Quorn, in SA's mid-north.
Ms Wild was reported missing by her family the night before and her body was recovered from a shallow grave at the Quorn cemetery.
At the time police said it appeared Ms Fullerton was murdered after she came across her killer with his first victim, Ms Wild.
The case was adjourned on Tuesday to the Supreme Court on October 14.
