Cape Town - Seventeen years after being part of a gang which raped and killed a 14-year-old teenager, a father of four has been sentenced to more than two decades behind bars.Elmario Maasdorp was handed 23 years behind bars for his role in the brutal murder of Valencia Farmer who was gang raped and stabbed 53 times in a deserted house in Eersteriver in 1999.Maasdorp appeared before Magistrate Deon van der Spuy on Tuesday, where the prosecutor confirmed the accused had entered a plea agreement.According to the document, Maasdorp confessed that he, along with three men who have already been sentenced for their part in the crime - Glenville Faro, Russel van Wyk and Franklin Roberts – had been drinking at a local shebeen, after which they left for a deserted house.Faro claimed Farmer was his girlfriend and apparently asked his friends "of hul wil naai" [if they wanted to have sex].Maasdorp confessed that all four had repeatedly raped and sodomised the teenager and then stabbed her.She was found naked hours later by residents, crouching in a passage of the deserted house.After managing to tell police who her attackers were, she died in Tygerberg Hospital.Maasdorp had previously decided not to apply for bail. Six men were initially arrested. Faro and Roberts received two life sentences each. They failed to get parole this year and would apply again early next year.Van Wyk, who was 16 when he was sentenced in March 2001, got 23 years in jail. Both of his parole applications, in 2013 and 2014, were rejected. In a statement, prosecutor Advocate Louis Van Niekerk, who was involved in the case from 1999 and the trial in 2001 when the accused were sentenced, said he and his team were relieved that all those involved had been imprisoned."Maasdorp never indicated why he participated in the rape and killing of Valencia. She was 14 years old, she had her full life head of her, there was no provocation and she was very vulnerable at the time," he said."Her gruesome death led to her mother's depression and we hope that she will find closure. She indicated that she was happy with the sentence."We then put her into contact with social workers so that she can get some help. We have done that today as well to ensure that she gets all the help... in order to close this chapter."
