A western Sydney teenager who disappeared more than 50 years ago was seen talking to two men in a panel van on the day she vanished without a trace.
Police now want to track down the pair as they try to determine what happened to 15-year-old Lynette Melbin and hope a $500,000 reward will prompt someone to come forward and help them uncover her fate.
Lynette was last seen at her mother's workplace - a supermarket on High St at Penrith - on June 5, 1972.
