POLICE yesterday confirmed that a skull found in Tin Can Bay forestry was damaged, possibly by a bullet or other weapon.
But regional chief detective Bruce McNab said all anyone could say at this stage is that "we just don't know."
He said police experts were attempting scientific reconstruction of facial features to help identify the dead person.
"We're also checking dental records of known missing persons and we're having DNA tests done.
"How long that will take just depends on how long it takes," he said.
"We're following up every line of inquiry.
"We're thinking that it may have been linked to the torso (found on nearby Cedar Pocket Rd) but we have to keep an open mind.
"That's an old police saying, but it is what we have to do," he said, explaining that if police make assumptions, they could miss something.
"We are not ruling anything out."
He said damage to the skull had yet to be investigated and he could not say one way or the other if it was a bullet hole or other sign of violence, or even if it might have been done by animals after the death.
"Human bones can become brittle with exposure to weather and time and animals can cause damage."
This did not mean the skull had been there for any particular length of time.
"It means we just don't know and we have to wait for results from testing."
He said thorough forensic testing of the skull was aimed at trying to identify the person and determine possible causes of death and whether it was recent.
