Cape Town - Why kill an old man for worthless goods?This is the question 80-year-old Eric Wiese’s sons Andri and Kobus want to ask the two people charged with his murder.The two, Vuyolwethu Mgemane, 30, and Nomfundo Mishawu, also known as Sisanda Kobus, appeared in the Cape Town Magistrate's Court on Monday. According to Netwerk24, they looked nervous and were restless in the dock.Andri and Kobus attended proceedings. Outside the court, Andri said it was the first time he had seen the two accused and that they did not know them.He said their father was probably assaulted and then strangled. They were likely linked to the crime through their fingerprints and were arrested with the help of the cellphone they stole, and CCTV footage, he said.Andri said the items stolen from the house were worthless. They included clothing, knives, and cash from Wiese's wallet."The cellphone is probably the most expensive thing they've taken and even that is not particularly valuable." Wiese, the former chief financial officer of Naspers, was found dead in his residence in Higgovale, Cape Town, on August 4.The accused were arrested in Gugulethu on Friday, after detectives traced location of the stolen cellphone.Mgemane and Mishawu asked for legal aid and said they would not apply for bail. Prosecutor Adenaan Jansen said the State would oppose bail. The court heard the police's investigation had not yet been completed.Mgemane and Mishawu are being held in Pollsmoor. The case was postponed to October 18.
