Time's done nothing to ease David Rosewall's broken heart.
His voice is all raspy emotion and his anger has grown as the days by tick with no news about his missing son.
It's been two years since Daniel Rosewall, then aged 28, vanished in outback NSW.
His fate remains a total mystery.
'You have an emotional hat on as a parent and you think he could be out there somewhere,' Mr Rosewall told AAP.
'But you say,'okay let's deal with reality' ... the reality is he could be dead.'
It was a sunny afternoon on January 27, 2010 when Daniel left the family business in Bendigo, in country Victoria, seemingly without a care.
He stopped at his girlfriend's house to pick up a credit card and then drove north in his mum's red Mazda.
It was not uncommon for the then 28-year-old to take off, occasionally seeking out peace and quiet at a local river.
He used the space to clear his head or just think about life.
But this was different.
Daniel ended up 750 kilometres away, north of Silverton - an area he'd never been to.
On the morning of January 29, the Mazda was found abandoned near Eldee Station, a family-run cattle farm surrounded by the ancient red desert featured in the Mad Max films.
The car's ignition was turned on, the battery was flat, the fuel tank empty and Daniel's personal effects, including his wallet and a $50 note, were on the seats.
He was wearing business shoes and not dressed for the 40-degree summer heat.
Various theories have been put forward for Daniel's disappearance, including the possibility he met with foul play.
But Daniel's father says he will never stop until he finds the truth.
'It's still a total mystery. It doesn't make a lot of sense,' Mr Rosewall continued.
'And it's still very much out of character for Daniel.
'There were no family issues, he was here at work the day he disappeared.
'Probably the last person to see him, a client of ours, said he was really happy.'
It's left the Rosewalls, like hundreds of families across Australia with missing relatives, in limbo.
There's been moments of hope along the way.
Not long after Daniel vanished there was a possible sighting in St Kilda.
Mr Rosewall and his wife, Julia, staked out a hotel where someone reported seeing him.
It turned out to be a red herring.
There's been darker moments.
On December 28, 2010 a fishermen discovered male human remains at Little Menindee Creek, part of Kinchega National Park, southwest of Broken Hill.
For several days there was speculation it could be Daniel.
Analysis has since suggested they were old Aboriginal bones.
And there's been proud moments.
In late 2010 Mr and Mrs Rosewall successfully lobbied the Victorian government to introduce new laws making it easier for families with missing relatives to handle their ongoing financial affairs.
They've also contributed to a new guide designed to help families that find themselves in a similar situation.
But all they really want is Daniel back.
Police confirmed there have been no new sightings.
Daniel's file, like the estimated 1600 other long-term missing persons cases, will remain open until he is found.
Until then Daniel's family, like others, can only hold onto hope.
'One of my granddaughters - she's three - said: 'I've got an idea, why don't we get uncle Dan's car and clean it all up for him and put it out the front',' Mr Rosewall added.
'He might see it and come home.'
Anyone who has information that could assist police and emergency services in finding Daniel Rosewall is urged to contact Broken Hill police on (08) 8087 0299 or Crime Stoppers on 1800 333 000.
A Facebook page has also been set up to aid the hunt for Mr Rosewall.
