Graaff-Reinet police said they have now opened a murder docket following a post mortem on the body of a baby found in a cupboard earlier this month.
Police spokesperson, Captain Bradley Rawlinson, said that the autopsy had revealed that the baby was alive when it was placed in a cupboard in a house in Kingwell Street.
In an earlier report, police said that a 22-year-old woman had given birth on Sunday, 8 September, and the baby's body was discovered a few days later.
At that stage, an inquest docket had been opened.
But, Rawlinson said on Monday that following the findings of the post mortem, the charge has now been changed to one of murder.
He said however that no arrests have been made and that investigators are still waiting for the findings of a DNA test.
