Police spokesperson Sergeant Ann Poortman said the incident took place at Wierdaglen Villa, in the Rooihuiskraal, area at about 5.15am, Rekord Centurion reported.
“The ex-husband went to his ex-wife’s house and found her with her new boyfriend. He shot the boyfriend twice before turning the gun on himself. He shot himself in the head,” she said.
Poortman added the man died on the scene, while the boyfriend was hit in the chest and upper left arm.
“The boyfriend was taken to Kalafong Hospital and is in a critical condition.”
Residents said they were woken by hysterical screams from a woman, followed by gunshots.
“I heard a woman screaming like crazy and a total of three gunshots straight afterwards. My husband and I went to check, and we saw two guys lying in a pool of blood,” said a neighbour who asked not to be named.
Poortman said an inquest docket has been opened, and an attempted murder was being investigated.
In October last year, a KwaZulu-Natal was sentenced to 15 years’ imprisonment after he was found guilty of murdering his ex-girlfriend’s partner.
Mlungisi Erik Hlongwane allegedly stabbed Sindile Othiniel Mwelase numerous times, while his girlfriend sustained a single stab wound.
Hlongwane later fled the scene, but he was later arrested after an anonymous tip-off to an off-duty detective.
