Wilma van Tonder, 42, a Lonehill housewife, was murdered on October 12.
Her five-year-old son is believed to have spent hours with her body before his father arrived home, Netwerk24 reported.
The child’s shirt was drenched in blood. He apparently asked the woman who allegedly assaulted his mother in front of him and stabbed her to death if he would kill her as well.
Norma Mudondo, the family’s domestic worker, was arrested at Florida Lake after the crime. She has been in custody since November after being denied bail.
