Search for murdered Qld pair uncovers nil A SEARCH of a site where police were hoping to find the remains of two Rockhampton housemates believed murdered has failed to turn up anything. Police and SES crews spent Thursday and Friday scouring land at Port Curtis, southeast of Rockhampton, following a tip-off that Chantal Barnett and Robert Martinez were buried there. "They searched the site for two days and found nothing," a Queensland police spokesman told AAP on Saturday. He said police were done searching the site but still working hard to solve the case. So far, they have uncovered some items of interest in a series of searches around Rockhampton for the missing pair. Earlier this month, officers scoured a Rockhampton riverbank for the housemates - two weeks after they revealed they'd found a bra and top, believed to belong to Ms Barnett, in bushland at Byfield. In June, police searched the Mount Morgan area following a tip-off about a silver car seen in the area at the time of the couple's disappearance. In May, they discovered a piece of jewellery after scouring deep gorges around Mount Archer. However, the jewellery was later found to have no connection to the investigation. On Friday, Detective Acting Superintendent Darrin Shadlow said police would keep searching until they found the pair's remains. "We will leave no stone unturned in relation to this investigation and if that means we have to do another 20 searches, we will do another 20 searches," he told ABC Radio. Ms Barnett, 27, and Mr Martinez, 26, were last seen in the Rockhampton/Yeppoon area in late February or early March.
