The parents of a young South African woman who disappeared along with her boyfriend 10 years ago while on holiday in Greece are appealing to anyone who might have information on the whereabouts of their daughter, Anita Swaak, who was 26 at the time she disappeared, or her boyfriend, Delarey McWilliam-Smith, to come forward. The couple disappeared on May 18, 1993. They were last seen on the Greek island of Naxos, on their way back to Athens en route to Italy. «It is our belief that some harm befell them either on Naxos or on their way back to Athens, but as no positive sightings were ever reported after Naxos, one cannot be absolutely sure. Many searches and appeals, some officially by our government and others privately conducted, have yielded absolutely nothing,» wrote her parents, Theo and Ilse Swaak. «We know that someone has harmed them and we appeal, we plead, that they, or anyone who has any information, let us know what happened to our daughter, by any anonymous way they see fit. We do not want revenge or reprisal. We merely seek closure to this nightmare,» they said. The Swaaks would like any information to be sent to P.O. Box 3381, Durbanville, 7551 South Africa, or for a telephone message to be left at the answering service at 0027.21.919.7130.
