The 23-year-old man Nathan Mowers, has been found guilty of the rape and murder of 17-year-old Lesley-Ann Maya in the Mossel Bay circuit high court.
The murder of the grade 11 learner from the Great Brak Secondary School in April 2015, sent shock waves through the community of Powertown.
Lesley-Ann was missing for eight days before her body was discovered barely 100m's from her home where it was hidden underneath an old carpet.
She had been raped and strangled with shoelaces.
Judge ET Steyn said during judgement that Mowers was the last person who was seen with Lesley-Ann before she went missing.
She said the fact that Mowers initially lied to investigating officers, telling them that he never had sex with the deceased, only to change his story when DNA linked him to the crime, was of critical importance to the court.
She found Mowers guilty of murdering and raping Lesley-Ann.
Steyn told Mowers that the court will give him a day to think if he would like to tell the court anything else, or tell the court if anyone else was involved in the murder, prior to delivering her sentence.
Lesley-Ann was the second learner from Powertown to have been murdered.
In October 2014 the 15-year-old Eloise Witbooi went missing and her body was discovered two months later.
Police said at the time that her body was too badly decomposed and therefore it would be impossible to determine the cause of death.
A third learner, also from the Great Brak Secondary School went missing two months after Lesley-Ann.
The 15-year-old Bonique Jansen was found dead in the same neighbourhood.
Police investigated the possibility that Mowers was involved in all three murders.
