Zeerust - A police officer based at the Mahikeng Organised Crime unit shot his girlfriend then turned the gun on himself, North West police said on Monday.
Warrant Officer Sachs Tlhowe Mothowagae was found alive inside a car at his sister's house in Welbedacht township near Zeerust around 3.45am on Monday morning, Brigadier Thulani Ngubane said.
It appeared the police officer had wounded himself through his mouth, Ngubane said.
He was taken to hospital where he later died.
Earlier that morning, Mothowagae had reportedly gone to his 42-year-old girlfriend's house where he and the girlfriend were last seen walking outside the house.
Later, a passer-by saw the girlfriend lying in a pool of blood outside her home. She had been shot behind her right ear.
Police were investigating, said Ngubane.
