Marcus Stanford has pleaded guilty to being an accessory to the murder of Stephanie Scott, ABC News reports.
Ms Scott’s burnt body was found in April last year in the Cocoparra National Park, about 70 kilometres from the town of Leeton, where she worked as a teacher at Leeton High School.
Marcus is the twin of Vincent Stanford who is accused of raping and murdering Ms Scott.
Vincent, 25, was arrested four days after her disappearance and Marcus was arrested in June of last year, charged with being an accessory after the fact.
He was extradited from South Australia to NSW at the time.
Marcus is expected to be sentenced in May.
