BONES have been uncovered by police in the Toolara State Forest as search crews hunt for more evidence linked to a skull found there two weeks ago.
Police are yet to confirm whether the bones are human, or what type of bones they are, but acting Inspector David Briese said a number of smaller bones - in addition to the skull - had been found in the forestry crime scene.
Acting Insp Briese said the bones had been found during a search earlier this week.
He said forensic testing of the bones was underway.
Detective Inspector Bruce McNab confirmed there had been "items of interest" located in the forestry since a second search of the crime scene began early this week.
He did not confirm what those items were or whether they had any link to the skull, but said numerous items had been collected from the area.
A walk-through search of forestry surrounding the area had taken place when the skull was found on April 10. A second walk-through search began early this week and Det Insp McNab said search crews were now into a hands and knees search of the ground in order to go through the area with a "fine tooth comb".
He said around three square kilometres of forestry around the skull's location had been covered by volunteer SES workers and police.
The site has been under police guard all week and is likely to remain that way until at least tomorrow.
The second search of the crime scene has extended the initial search site, with about 65 SES volunteers and police assisting.
Acting Insp Briese said Gympie Criminal Investigation Branch detectives and a homicide squad from Brisbane had been part of the operation.
Forensic results relating to the skull, found in Toolara Forestry around 5km along Cooloola Coast Rd turn-off from Tin Can Bay Rd, are expected to be back to police next week.
Digital remodelling of the skull is also expected to be undertaken by police in a bid to identify the victim.
In the meantime police are asking everyone to think of any males between the ages of 40 and 80 they have not seen since last September.
They are also appealing to the public for information of any suspicious activity that may have occurred around the Toolara Forest.
Anyone with information is urged to call Crimestoppers on 1800 333 000.
