POLICE divers who spent the past two days searching Lake Awoonga are yet to find any evidence relating to the disappearance of Robert Martinez and Chantal Barnett.
Divers will continue to search the Gladstone waterway today after several tip-offs from the public.
"I've had no feedback that anything of interest has been found," said Detective Senior Sergeant Scott Moon yesterday afternoon.
Police were led to the area after receiving several important pieces of information which helped shed more light on what could have happened to the Rockhampton pair more than a year ago.
They were last seen in February last year and last heard from last March.
Lake Awoonga covers more than 67 square kilometres, however police will only be searching specific areas they have identified.
Yesterday Det Snr Sgt Moon said police were very happy with how the investigation was progressing and still had information coming in regularly from the public.
"We are still confident we've spoken to the person or persons responsible for the murder of Robert and Chantal, and they should be worried," he said.
"We don't give up."
