The Durban father who killed his three biological children and stepdaughter was sentenced to four life terms in jail.
Judge Sharmaine Balton when handing down the sentence to Sibusiso Mpungose in the Pietermaritzburg High Court said his actions were "horrendous" and "inhumane".
He pleaded guilty in October to hanging his children aged 4, 6, and 10 at their family home in Wyebank on September 3.
His 16-year-old stepdaughter was strangled with a bathrobe belt and found in the bush in Padfield Park, Pinetown.
Balton said the post-mortem results of the deceased children painted a "gruesome picture of the resultant injuries of the strangulations".
"One can only imagine what must have gone through the minds of these vulnerable children when you committed these heinous crimes. They loved and trusted you as their father," she said.
Last month, He told the court that he committed the murders because he suspected his wife was cheating on him with the father of her first child and suspected this was the real reason she had asked to divorce him.
He will return to court to face additional charge of rape.
