Andre Kirsten would represent him.Pearce was found dead in her mother's flat on the fourth floor of an apartment building in Sea Point on December 2. She had been stabbed in the stomach, and some items were missing from the flat.At his last appearance, the prosecutor asked for a postponement because a witness report and scene photographs were still outstanding.
