SA nurse's alleged murderer to face court

A man accused of murdering a nurse who went missing while working near a remote community in South Australia's far north is due to face court.

The body of Gayle Woodford, 56, was found in a shallow roadside grave near Fregon on Saturday.

Ms Woodford's body was found four days after she was last seen on Wednesday night in the state's Anangu Pitjantjatjara Yankunytjatjara (APY) Lands.

Her disappearance sparked a wide-scale aerial and land search on Thursday amid police concerns Ms Woodford was taken from her home.

The ambulance she normally drove was intercepted by police at Coober Pedy on Thursday, with two men and a woman inside.

A 36-year-old Mimili man was arrested and initially charged with the theft of the ambulance before he was charged on Sunday with Ms Woodford's murder.

He has been remanded into custody and taken to Port Augusta, where he is due to face court on Tuesday.
