Helga van Wyk, a teacher at Monument Park High School in Kraaifontein, was found murdered in her Durbanville home on Monday.
Helga and her husband Johann were at their home when assailants broke in.
While defending his wife against the attackers, Johann was stabbed several times and Helga tragically died in the attack.
According to police spokesperson Captain FC van Wyk, Helga and Johann’s son came to his parents’ home on Monday morning and discovered his mother’s body and his father in critical condition.
Johann’s injuries were so severe that he required surgery and he is currently being treated at Durbanville Mediclinic.
