“My concern is that we may never be able to categorically say that we know this person’s identity.”
The following quote taken from the ABC transcript of ‘My Name is Charles’ Australian Story.
“I’m not sure we’ll ever be absolutely certain (Carl Webb is the Somerton Man), because what we would do in a forensic context normally is take a deceased DNA and compare that directly with something we know belonged to them, a toothbrush, a hairbrush, etcetera, and extract DNA from that item.
We haven’t got that here.
As a secondary measure, we could compare the deceased DNA to a very close family member, you know, parents, children.
Again, we don’t have that.
So my concern is that we may never be able to categorically say that we know this person’s identity.”
DR Xanthe Mallett, Forensic Scientist at the University of Newcastle.

“The plaster bust was moulded directly off the dead body. So the hairs are actually standing on end in a manner that is obviously from the body.”
Professor Derek Abbott.
“It’s important to note that the DNA used by Professor Abbott and his team was not extracted from the body; but rather from hair fibres found on the original plaster cast bust.”
Fiona-Ellis Jones, broadcast journalist.

toothbrush, comb etc just the things that could have helped with DNA, dumped, per GF, in 1980s. And Tibor had also been in the frozen section of the morgue.
