Kgaogelo Nnonu murder: Boyfriend admits killing in social media posts
A young woman, identified as Kgaogelo Nnonu, was allegedly stabbed to death by her boyfriend outside a tavern on Thursday morning in Hammanskraal, Gauteng. Following the incident, the man admitted to the killing in a social media post.
Reports indicate that the suspect attacked Nnonu repeatedly with a knife before fleeing the scene. He later shared a lengthy account online, attempting to justify the horrific murder.
“They may judge me, but you and I know the truth, you ruined us, as I posted everything on (the) app it will prove that. RIP. I promised you till death do us apart after I fought for your life. Will forever love you Mmamogashwa,” he posted on Facebook.
In a video that has since gone viral, he apologised for the violent incident and claimed that it was not his intention to kill her.

He claims he did everything possible to make the relationship work but alleges that the victim’s mother pressured her into taking out protection orders against him, even though he insists he was no longer in contact with her or causing any trouble.
“I tried by all means to make things work between me and her…I’m sorry for what I did. It’s just that I cannot reverse what I did. I’m supposed to be raising and loving my kids,” he said on a video he posted to TikTok.
Nnonu’s father also took to social media to address the alleged killer and the videos he posted.
“Kgaogelo was my child. She was born in the 2000s and she has been killed by her boyfriend… I saw her body in the pathology service vehicle, and I’ll be burying her next week Saturday,” he said.

This case bears a chilling resemblance to an incident in December 2024, when Sibusiso Lawrence from Scottburgh, KwaZulu-Natal, posted a graphic image of a woman whose throat he had slit.
He also uploaded a video of himself with his face covered in blood, in which he admitted that the woman was his girlfriend and confessed to killing her.
In the disturbing video, he said: “You will say I’m violent. You will say I’m violent. I tried… I have worked hard in my life trying to satisfy a woman. I was trying to make her happy.” Lawrence was subsequently found after dying by suicide.
