After Edmund Ian Riggs lied to his wife Patricia's family for nearly two decades about killing and burying her, saying she had abandoned their four children, he has been asked to do one thing.
Reveal where her unrecovered remains are.
The couple were arguing in their bedroom in Redcliffe, north of Brisbane, when Riggs pushed her, inadvertently killing her after a troubled 17-year marriage.
A Brisbane Supreme Court jury acquitted him of murder on Wednesday and instead found the 60-year-old guilty of manslaughter.
The jury accepted his testimony that Patricia died after he pushed her in reaction to her spitting on him on September 30, 2001.
She fell back and hit her head on the bed, sparking his panicked cover-up efforts including burying her in a shallow grave on the outskirts of Caboolture in the dead of the night.
The next day when her children asked for her, he claimed he didn't know where she was, later telling friends and family she had run off.
But Patricia's family had their suspicions about him "right from the start".
"The story just didn't match," her brother Mark Knowles said outside court on Wednesday.
"Patricia was a loving parent. She never wanted to be away from the children.
"He's lied everywhere in there. It's just another lie. His lies have become natural."
Years later, Riggs dug up her remains after seeing heavy machinery at the first burial site, in fear of discovery.
He reburied her at the family home, where her partial skeletal remains were found in 2016 by a new owner.
Not all of her remains have been found.
Riggs kept lying until his trial last week when, at the start, he pleaded guilty to misconduct with a corpse.
In court, he laid bare his troubled marriage.
He and Patricia fought over his failure to financially contribute to the family due to a work injury.
On the night she died, Riggs said, Patricia laughed when he claimed he wanted to make peace.
Riggs said his wife told him she'd found a list of escorts in a pocket of his shorts.
Then she revealed she'd had numerous affairs with men she'd met through swim coaching and at nightclubs.
When he realised Patricia was dead, he says his brain "exploded".
Fear that their four children would be "orphans" if he was jailed prompted him to cover up the death, he said.
Disappointed by the verdict, Patricia's family believes he has shown no remorse.
"He's got one thing he can do for the family now," Mr Knowles said.
"Give us the rest of her remains so we can bury her with dignity.
"Where is she? Only he knows the answers. If he's got any ounce of dignity, he'll let us know."
He will be sentenced at a later date.
