Johannesburg – Jacobus Oosthuizen will appear in the Paarl Magistrate's Court on Thursday for the murder of Nicola Pienaar.
Oosthuizen, 32, led officers to his home in Paarl, Western Cape, on Sunday where Pienaar's body was found buried under rubble.
He was arrested in Port Elizabeth on January 21 after he was found driving Pienaar's car. It was packed with clothes and other items.
Oosthuizen appeared in the Port Elizabeth Magistrate's Court on Friday.
Pienaar, 28, went missing on January 5.
Her mother, Marlaine Pienaar-Vice, reported her missing on January 8 and opened a case of motor vehicle theft.
In January, Marlaine told News24 that Oosthuizen was a friend of her daughter's and that she never had any problems with him.
"When I met him, he was just a normal man to me and I didn't think badly of him at all. At this point, I don't think I should judge. I will wait for proof," Marlaine said.
Pienaar lived in a flat at her mother's psychology practice in Paarl.
