Three kids aged twelve, four and three were found burned beyond recognition inside a car at Bosplaas West, North of Pretoria on Tuesday.
An unknown eye-witness noticed a burned vehicle and bodies in the bushes and informed the police.
According to police, the kids were reported kidnapped by their 30-year old mother the night before they were found dead. She said her boyfriend had taken the kids while she was not around and threatened to kill them.
The two young boys belong to the girlfriend who opened a case of kidnapping and the three year old boy belongs to her younger sister.
