On 27 December 2018 at about 18h00 in Reiger Park, Boksburg, Gauteng, a fight broke out between the deceased, Wendell Pietersen, and his friends over money. The deceased threw stones at his friends on Forel Street. Mr de Klerk had just arrived from work and was seated on a bench next to neighbours. The deceased threw stones, one of which hit a neighbour's gate with a hard impact. When the deceased returned armed with a half-brick, Mr de Klerk stood in his path to stop him from throwing further stones. The deceased swung at Mr de Klerk with the half-brick. Mr de Klerk ducked and produced his firearm to scare the deceased. The deceased grabbed the firearm by the barrel, and during the scuffle for control, Mr de Klerk's forefinger accidentally slipped into the trigger guard and pulled the trigger. The deceased was shot in the chest and died. Mr de Klerk drove to the police station to report the incident. The Regional Court convicted him of murder with direct intent and sentenced him to 15 years' imprisonment. Leave to appeal was refused by both the regional court and the high court on petition.
