Might have been someone lost at sea...
Maybe. They said the skull was really weathered and aged it will take them 2 weeks to do the testing to find out how old it is and what age and sex the person was. The fact that its an aboriginal skull everyone concerned with its finding have clammed up.
Why is this???
Let's assume that the skull is a couple of hundred or more years old.
There is no chance any of the finders are guilty of killing him.
