Eddy Mol could never forget the sight of his infant son Timothy in a white coffin at Norwood Park Crematorium.
He died hours after birth in 1978.
The birth was already an unlikely one. Mr Mol's then wife Ruth was a semi quadriplegic and told she couldn't have children.
Ever since his death Mr and Mrs Mol would visit his ashes and lay a flower.
After his ex-wife died, Mr Mol went to retrieve the ashes to fulfill his wife's last wish - to have both their ashes scattered at Mount Kosciuszko.
It was then he was told by Norwood Park the ashes could not be found.
But Mr Mol's grief has recently been compounded, when Norwood Park suggested he or another family member might have already taken the ashes.

In a response to an audit of claims of lost ashes, Norwood Park said that Mr Mol's memory was "somewhat hazy" and on two occasions could not be certain the ashes had not already been taken.
For Mr Mol, that suggestion was just another kick in the guts from what has already been a painful ordeal.
"The old trick is turn the tables, it is just made up. You never forget the white little coffin laying there at the crematorium," he said.
"The third time I spoke to them ... they said they were trying their hardest to find the ashes, nothing about someone taking the ashes already.
"We always believed he was there. We visited every year for his birthday.
"Knowing all those years when we went and visited the crematorium he wasn't there ... I was devastated."
As a result of an investigation after Mr Mol came forward, two other families were reunited with their children's ashes, but Timothy's remained lost.
Member for Ginninderra Tara Cheyne said the suggestion Mr Mol's memory was "somewhat hazy" was surprising and disappointing.
"I find it hard to believe Eddy would forget something as momentous as collecting or removing his son's ashes," she said.
"Until he was told otherwise in 2017, he has always believed Timothy's ashes were at Norwood. Eddy has been a diligent record keeper. He still has the letters from the 1970s confirming a memorial had been created for his son in the Children's Niche Wall, where ashes were interred.
"That Norwood is even commenting on someone's memory is because their own record keeping wasn't, and still isn't, up to scratch.
"In addition to Timothy's missing ashes, the audit report identified further anomalies regarding the location of other ashes."
Ms Cheyne said Norwood should focus its efforts on ensuring no family had to go through what Mr Mol went through again.
"Without Eddy, more families would still be suffering. The community deserves better from an organisation trusted with the care of loved ones," she said.
"And Eddy deserved - and deserves - better."
Norwood Park declined to comment further on its suggestion Mr Mol had a "hazy" memory.
