The two sisters who were shot by a police constable in Emdeni, Soweto, on Sunday morning, are still alive after being resuscitated, Gauteng police said.
"The girls were resuscitated and were taken to hospital," Warrant Officer Kay Makhubela said.
"They are in a critical condition."
Earlier, police said a 27-year-old police constable shot and killed the girls and then shot himself.
But Makhubela said he was later informed that emergency workers managed to resuscitate the sisters.
The motive for the shooting was unknown.
Makhubela said the man was stationed at the Booysens police station.
Police opened inquest and murder dockets.
