National Network News journalist Ian Ross reports on the ongoing investigation into the murder of two teenage girls who were found buried in shallow graves in the sand dunes at Wanda Beach in Sydney's south.

Ross interviews Detective Inspector Haynes, who is in charge of the murder investigation. This is followed by silent footage of Ross and the Detective Inspector at the location where the girls were found.

The girls were identified as Marianne Schmidt and Christine Sharrock, from Ryde in NSW. Both were aged 15 years.

Despite a widespread investigation, the identification of a number of suspects and interviews with thousands of witnesses, this case is still unsolved and no one has ever been charged with the murders.
