The Breyten High Court has sentenced John Ntobeko Sibeko (37) to 20 years’ direct imprisonment after he pleaded guilty to the murder of his girlfriend, traditional healer Priscilla Mndebele.
Details of the offence and plea
The sentencing hearing took place on 21 August. Sibeko entered a plea in terms of Section 112(2) of the Criminal Procedure Act 51 of 1977, admitting that his conduct was unlawful and punishable by law, the National Prosecuting Authority (NPA) provincial office said.
According to the plea statement read into the record by Sibeko’s legal representative, the fatal incident occurred on 14 October 2025 at Sibeko’s residence in Emzinoni, within the Govan Mbeki Local Municipality. The NPA said an argument began after Sibeko received a telephone call instructing him to report for duty at Sasol and raised a question about his access card. Mndebele reportedly told him her ancestral spirits were against him going to work, and the conversation escalated into a physical altercation.
During the altercation Sibeko took a wire and strangled Mndebele. He later locked her inside the home and informed members of her family of what had happened. Family members and neighbours forced open the door and found Mndebele’s body on a bed, the NPA said.
"He admitted that his conduct was unlawful and punishable by law,"
In court, the state presented a post-mortem report confirming the cause of death as strangulation.
Aggravation, impact and sentencing considerations
The charge was prosecuted as murder read with the provisions of Section 51(1) of the Criminal Law Amendment Act 105 of 1997 because the offence arose within the context of a domestic relationship.
The court received a victim impact statement from Mndebele’s mother, compiled with the assistance of a court preparation officer. The family described the emotional trauma and enduring pain left by her death, portraying Mndebele as a loving and supportive family member whose loss created an irreparable void.
State prosecutor Amos Mtshweni presented the post-mortem findings during the sentencing proceedings. The NPA’s provincial spokesperson, Monica Nyuswa, confirmed the conviction and sentence.
Local context and broader concerns
Domestic-related murders remain a pressing concern in many parts of the province. This case, in which the court applied provisions of the Criminal Law Amendment Act that relate to offences within domestic relationships, underscores how the justice system treats intimate-partner violence with particular seriousness.
The plea process under Section 112(2) allows an accused to admit the facts and be convicted without a full trial if the facts amount to the offence charged. In this matter, the court accepted Sibeko’s guilty plea and convicted him as charged before imposing the custodial sentence.

Practical information and support
Domestic-violence survivors and families seeking assistance can contact local SAPS stations to report incidents. Support services and victim‑support organisations operate in many municipalities to provide counselling and court-preparation help; in this case a court preparation officer assisted Mndebele’s family in compiling a victim impact statement.
