Childline has reacted with outrage to the murder of Sheldean Human.
The seven-year-old girl disappeared 15 days ago from her parents's house in Claremont, Pretoria West.
On Monday evening her body was found in a stream behind the Tshwane fresh produce market.
For more than two weeks neighbours and police teams searched tirelessly for her.
The searchers came as close as 200m from where she was found.
Superintendent Piet Byleveld, the policeman behind the capture and conviction of Donovan Moodley, killer of student Leigh Matthews, was given the whereabouts of the Sheldean's body by Andrew Jordaan, her alleged killer.
A Johannesburg daily newspaper reports that Jordaan appeared to be obsessed with Matthews' murder.
Police discovered a collection of newspaper clippings about the 21-year-old's abduction and murder, and a photograph of Byleveld, hidden in Jordaan's room.
When this discovery was made Byleveld was asked to help.
He agreed and his interview with Jordaan led to the police gaining information about the location of the little girl's body in Pretoria West.
Childline said the murder of Sheldean showed that gross violations of children are still being perpetrated.
"It is absolutely terrifying to think that the most vulnerable members of our society are being murdered like this," said Lynne Cawood of Childline.
"Last year it was Judge Ngoepe's granddaughter, and now this happens, on the anniversary of her death," she said, referring to Makgabo Matlala's murder.
Makgabo, 4, was killed last year in her parents' house during a robbery in which her 57-year-old nanny was gang-raped.
Sheldean was murdered barely a month after the gruesome gang rape and killing of Thato Radebe, 14, whose body was found in the veld in Emdeni, Soweto.
Five youths have appeared in the Protea magistrates' court.
Cawood said that since April Childline had dealt with 209 cases of missing children.
"Some were probably runaways, but many were reported as abductions," she said.
Childline wants people to wear jeans and a pink top - the clothes Sheldean was wearing when she disappeared - on Friday to commemorate her death.
