After then unsuccessfully “hunting” for his girlfriend, Fuzani turned the gun on himself.
The Independent Police Investigative Directorate (Ipid) said they were now investigating a murder and suicide case. The incident happened in Thembalethu, George.
“Ipid received a report of the discharge of a police firearm by an off-duty policeman on Friday. It is alleged that the police sergeant, based at SAPS Middelburg in the Eastern Cape, shot and killed his girlfriend's 30-year-old sister in Thembalethu.
"It is further alleged that after the killing, the suspect went hunting for his girlfriend, who is also a member of the SAPS in Middelburg.
“Failing to trace his girlfriend, the suspect realised that the police were looking for him and he then decided to flee the area in his private car.
"He managed to commit suicide by shooting himself with the firearm, some 200km away from Middelburg,” said Ipid spokesperson Sontaga Seisa.
Women and child rights activist Lucinda Evans said: “We need to ask what resources are available to police officers who suffer domestic and gender-based violence.
"They also suffer through the trauma of all the scenes they are exposed to. Some officers do not want to report this to their Employee Health and Wellness Resource.
"They feel they can't go to their own source of help because they fear the effect it may have on their positions.”
