On 16 May 1998, seven men arrived in Port Nolloth in a white minibus. That night, Mr Joaó Carlos Moutinho and Ms Vivian Lotz were shot dead in a house in Port Nolloth. Lotz was shot three times and Moutinho seven times. Moutinho's BMW was stolen along with other property including money from a safe. The word "cowboy" was scrawled in blood on the wall above the bed. Five men drove off in the stolen vehicle, while two waited in the minibus. The five occupants abandoned the vehicle midway to Steinkopf and were driven to Vanrhynsdorp where they reunited with their two companions. The appellant and six others were arrested and charged. Two accused died before trial. At trial, the second accused was acquitted of all charges, the first accused was convicted only of theft of the vehicle, while the appellant and the fourth and fifth accused were convicted of two counts of murder, robbery with aggravating circumstances, and theft. The defence evidence suggested the visit was to sell diamonds to Moutinho, an illegal diamond dealer. The trial court accepted it was reasonably possible the accused had no common purpose to commit murder and robbery when they arrived at the house.
