Police have released new computer-generated images of two individuals believed to be linked to two cold case murders that have remained unsolved for more than two decades. The renewed investigation focuses on the disappearance and suspected murder of 45-year-old Iain Stewart in Tweed Heads, New South Wales, as well as the fatal shooting of 67-year-old Frederick Hugh Rosson, known as Slim Johnson, at Mount Nathan in Queensland.

The images were created using witness descriptions collected in 2002, supplemented by information obtained through a public appeal launched two years ago. Authorities hope that sharing the updated likenesses will encourage people with any relevant information to come forward.

Detective Sergeant Scott Chapman, leading the inquiry, emphasized that the passage of time may have altered relationships and allegiances, potentially freeing individuals who were once reluctant to speak to now provide crucial details. “Twenty-four years have passed and relationships and loyalties change,” he said. “People who may once have been afraid to speak may no longer feel that way.”

To assist in solving the cases, law enforcement agencies in both New South Wales and Queensland have jointly offered a reward of up to AUD 1 million for information that leads to the conviction of anyone involved in the deaths of Mr. Stewart and Mr. Rosson.

Members of the public with information are urged to contact Crime Stoppers at 1800 333 000. The authorities continue to seek tips that might finally bring closure to these longstanding investigations.
