CSI SA: The creepy-crawly cops

What Lieutenant Melanie Pienaar stared at under her microscope made no sense. Pienaar is a forensic entomologist who helps to establish the time of death in police cases. Often the kind of insect discovered on a body and the level of decomposition indicate how and when the victim died.What Pienaar found on the body of eight-year-old Kiana Williams was the maggot of a fly that appeared to have been in the wrong place at the wrong time.
