The court heard last week how both men had submitted statements to the police.
It was also revealed, however, that the two appear to not be in good terms, with the younger man saying that Khupe had threatened him.
Neighbours of the Vlakfontein family alleged that Khupe had been involved in a romantic relationship with one of the women who was found killed and buried in a shallow grave in the family home. They had been dating for at least a decade.
The 27-year-old suspect was alleged to have introduced himself to the Khoza family under the false name of Sibusiso Khoza, stating to be long-lost relative. He connected with them via Facebook.
The court has since heard that this was not his real name and he is an illegal immigrant from Zimbabwe. He was arrested while trying to cross the border back to Zimbabwe just days after the decomposed bodies of the family members were found by police.
