JOHANNESBURG - South African police said Sunday they have discovered the frozen corpses of four newborn babies in freezers at a house in the southern city of Mthatha. Acting on a tip-off, police raided a house on Saturday and made the grim discovery of the infants estimated to be aged between just one and two months. ‘The babies were found in two freezers,’ police spokesman Mzukisi Fatyela told AFP. Police are looking for the owner of the house, a woman, who was away in Johannesburg at the time of the search.
