Former radio personality Donald Sebolai has accepted that if he had only "applied his mind" and taken his girlfriend to hospital, she might still be alive.A tearful Sebolai made this admission yesterday when testifying in mitigation of sentence in the Johannesburg High Court, sitting at the Palm Ridge Magistrate's Court southeast of Johannesburg.Sebolai, 38, also known as DJ Donald Duck, was convicted in October of murdering his girlfriend Rachel "Dolly" Tshabalala, 32. Sebolai stabbed Tshabalala in her lower abdomen after the couple fought at his Soweto flat, and she bled to death.Though Sebolai maintained that he did not cause Tshabalala's death by stabbing her, saying she stabbed herself in a tussle, he admitted that he could have saved her.He said, however, that due to his own injuries and the blood on the floor he was in shock and unable to act sensibly.The court heard previously that there was a hospital just 900m from Sebolai's flat, where Tshabalala died.Sebolai sobbed uncontrollably as he remembered the ordeal and had to pause frequently before continuing with his testimony.Sebolai told the court that he regretted Tshabalala's death."Her family needs her, and I still need her," he said.But prosecutor Elize le Roux challenged Sebolai and said his only regret was getting caught.Le Roux told him that she would argue, in aggravation of sentence, that Sebolai's history showed a pattern of violence against the women in his life...
