The Johannesburg businessman and IT engineer who murdered his wife clearly has "no respect for life".These were the words of magistrate Vincent Pienaar when he sentenced Tshimologo Huma to 20 years behind bars at the Randburg Magistrate's Court in Johannesburg on Tuesday.Huma‚ 38‚ chased down his wife‚ Carla‚ 32‚ and stabbed her to death in December 2011 after the couple had had a fight at Huma's internet café in Cosmo City‚ northwest of Johannesburg.Carla fled to the nearby house of a friend. Huma followed and the couple argued again‚ after which Huma kicked‚ dragged and stabbed her repeatedly with a blunt knife.Huma pleaded not guilty to murder and said that Carla provoked him by spitting in his face‚ but the court convicted him of murder in July last year.“Because of the brutality of the murder I've decided an appropriate sentence is 20 years‚” Pienaar said.Carla's family members and friends sobbed in court as Pienaar read out the details of each of Carla's 13 wounds to illustrate the brutality of the crime.Pienaar said that the injuries were so severe because the knife used to kill Carla was blunt.After the sentence was handed down‚ Carla's brother Mothusi Legwale said: “We as a family feel relieved. We welcome the sentence. It will serve as a deterrent to other murderers.”According to a pre-sentencing report‚ Huma was abused as a child and has a short fuse.It also emerged during sentencing proceedings that Huma is in a relationship and has a two-year-old child with his girlfriend.He and Carla had a daughter who is now seven years old and lives with Carla's mother‚ Aphathia Legwale‚ in Mahikeng‚ North West...
