His family reportedly said he had gone target shooting, when he was shot in the back by unknown attackers. According to local newspaper Zoutpansberger, the family was renting a house on the smallholding, which belongs to Strydom's employer. At the time, Rieta, Hendrik and Strydom's other son, Pieter, 24, were reportedly interrogated by police. Rieta is the stepmother of two of the sons. Zoutpansberger reported that Strydom's two sons had gone looking for him when it became dark and had found his body lying face down near his bakkie. They then reportedly turned him around and found that he was dead. His firearm was missing. Shooting was a mysteryThe shooting was, however, a mystery. It was speculated that he could have committed suicide or that his death could have been the result of a shooting accident. Rieta told the local paper that she was "upset" about rumours that she was one of the main murder suspects."I am being told that I shot him for his money... I am sick and tired of these stories," she is quoted as saying. "Someone even called me from the Free State and said they had heard that his sons had shot him."Rieta reiterated this in an interview with Afrikaans Sunday newspaper Rapport in 2016. "What money?" she wanted to know. Rieta and Hendrik have been released on bail of R1 000 each and will appear in the Louis Trichardt Magistrate's Court again on May 24, Netwerk24 reported.
