Donna Louise Howe was last seen by her daughter at a Mother's Day dinner on May 8, 2022, a court was told.
Tiana Jade Howe called and texted her 57-year-old mother multiple times afterwards but did not receive a response.
Her mother's body was found a month later in the Glass House Mountains on the Sunshine Coast Hinterland.
Clinton Travis Oliver and Braydon Franklin on Monday both pleaded not guilty to murdering Ms Howe.
They both pleaded guilty to interfering with a corpse by taking her body to a remote mountain track and dousing it with petrol before setting it alight.
Crown prosecutor Nathan Crane previously alleged Ms Howe was tied up and killed in her own home after "growing animosity" with Oliver and Franklin over claims she was stealing from their partners.
Oliver was living in a room at Ms Howe's Caboolture house with his partner at the time and Franklin was a frequent visitor as his partner also lived there.
Ms Howe's daughter told the jury she was able to access her mother's house after she disappeared, finding her mother's personal items in her bedroom such as clothes, a toothbrush and makeup.
She spoke with Oliver who said her mother had "gone on holidays", the Brisbane Supreme Court jury heard.
Oliver claimed unknown people had picked up her mother and taken her to Gin Gin, more than 300km away, the daughter said.
She later called police to report a missing person.
Ms Howe's daughter did not return to the house until after her mother's remains had been found and police had completed a forensic search of the property.
The jury heard she found some of her mother's possessions had been moved to different places around the house including to the bedrooms of Oliver and his partner.
She also found her mother's distinctive jewellery in Oliver's bedroom, the jury was told.
Under cross-examination from Franklin's barrister Damian Walsh, Ms Howe's daughter agreed her mother had wanted Oliver to stop living in her house because of the mess caused by his repair of cars and motorbikes.
The moment Ms Howe's skeletal remains were found was detailed to the jury on Monday.
Bayley Travis O'Day testified that he was on a Glass House Mountains four-wheel-drive trip on June 7, 2022, when his group was stopped by overgrowth on a disused dirt road.
"That's where we found the remains. I didn't really know what it was until I got out of the car," he said.
"For some reason I just had a bad feeling, I didn't really recognise what it would be so I thought I'll just check it out."
The trial continues before Justice Martin Burns.
