Xolile Mngeni - Dewani's killer - was diagnosed with a brain tumour in 2011 while awaiting trial, but was convicted to life imprisonment thereafter. His application for medical parole was later denied in July this year.
Criminal law expert, William Booth:
We don't know who all the state witnesses are because the list of witnesses has not been made available, so it's kind of waiting for the prosecutor to call on a witness. I personally don't believe Mngeni would have been called as a state witness. He pleaded 'not guilty' to the charge, and after a fairly long trial, he was convicted and sentenced to life imprisonment on the murder of Anni Dewani and various other charges. His credibility during that trial was affected.
