Seventeen-year-old Maduo Mafubedu was buried on Saturday after she was brutally raped and her throat slit by unknown criminals.
In a moving ceremony on Tuesday night, she was posthumously honoured by her school, Randeor High, at its yearly sports prize-giving event in Winchester Hills, south of Johannesburg.
The grade 11 pupil received two trophies and six certificates for her participation in sports, including running, javelin, long jump, marathon and soccer.
Masodi Mafubedu, her mother, said: "We are happy that the school went ahead and honoured her. She may be dead, but I am happy that her talents are being recognised."
The pupil from Pimville, Soweto, was found in open veld in Klipspruit Extension 4 on Sunday, April 15. Police said she had been raped.
Her mother said they last saw her on Friday, April 13, when she left home to attend a friend's family wedding in Diepkloof.
She was with friends, three girls and three boys.
"She wanted me to come as well, but I could not make it. She did not return home that day or the next," her mother said.
The friends said they last saw her at the wedding.
Mafubedu identified the broken body of her daughter at the government mortuary the day after she was found.
On Tuesday, Mafubedu heard that her daughter was a multi-talented girl who was destined for great heights. She participated in almost every sport the school offered and did well academically too.
Her sports mates described her as the school's "Ace" when they delivered emotionally charged tributes to her. They and her teachers spoke of what a bubbly, friendly girl she was.
The moving ceremony brought her family to tears as her mother walked up onto the stage to receive the awards.
Maduo played soccer for Kaizer Chiefs' female team.
She had represented her school and province in major sporting tournaments, achieving national colours.
