A Victorian man has appeared in an Adelaide court charged with the cold case murder of his aunt in 2010.
Steven Leslie Hainsworth, 44, is accused of killing Beverley Hanley at her home at Elizabeth, north of Adelaide.
Police prosecutor Sergeant Peta Rayson told Adelaide Magistrates Court on Friday the case comprised complex electronic evidence and would involve DNA testing.
She said investigators would work through 240 statements, and asked for a six-month adjournment.
Lawyers for Hainsworth did not object to the request, and made no application for bail.
Outside court, Ms Hanley's daughter, Robyn Schaefer said the family were relieved at the arrest.
Her daughter and Ms Hanley's granddaughter, Tasha Hanley, thanked police who worked on the case "to make sure that we now see justice be done".
"That is exactly what we are here for and that is exactly what is going to be done," she said.
"It makes me sick but I wanted him to know that we were here, we're waiting.
"He knows we're all there, he knows he has no supporters: we're it."
Hainsworth, from Mildura, was arrested in Victoria on Thursday and extradited to South Australia following a hearing in Melbourne.
Ms Hanley, 64, was found dead in her Elizabeth North home in October 2010, and last year police said they had fresh forensic evidence relating to her death.
She suffered severe head injuries, her home was ransacked and her handbag stolen, detectives said.
Hainsworth was remanded in custody to reappear before the court in November.
