SHAUNE Gibson was lured into a house, thinking he would reunite with a former girlfriend, when he was strangled to death with wire.
While naked in the shower, Mr Gibson, who was 19 at the time, was attacked and had his hands and feet bound with wire.
He was hit with a pool cue and scratched with a machete before being strangled to death.
But the horror - which yesterday resulted in two life sentences for murder - did not stop there.
Mr Gibson's lifeless body was then wrapped in a tarp, dumped into a car and taken to be buried in a grave on a Churchable country road.
Warrick David Lindenberg, 29, stabbed Mr Gibson's body in the back twice to make sure he was dead, and then buried him.
Lindenberg and Valerie Jeanette Mullins, 47, must serve a minimum 15 years behind bars for Mr Gibson's murder and for interfering with his body.
The horror which unfolded that night in August 2012 was detailed in Brisbane Supreme Court on Tuesday.
Judge David Boddice said both Mullins and Lindenberg had committed despicable acts.
But he said what they did after burying Mr Gibson was even more callous.
Five days later, they returned to the gravesite to make sure he was still there, digging until they could see his lifeless arm.
They then stopped at McDonalds at Gatton on the way home, the court heard.
Justice Boddice said that night he was murdered would have been a "truly frightening" experience for Mr Gibson.
"He was not only assaulted in the bathroom but he was then tied using wire, taken to the bedroom, assaulted again and questioned before being strangled, which would be a horrible death for anybody," he said.
"This was all part, I am satisfied, of a plan both of you had reached."
Justice Boddice said the pair showed no regard for Mr Gibson's dignity.
Last week a jury found Mullins, also known as Chambers, guilty of Mr Gibson's murder. She had pleaded guilty to manslaughter but would not accept she intended to cause harm.
Lindenberg pleaded guilty to murder.
The court heard Lindenberg eventually confessed his crimes to police but initially tried to convince them bikies were to blame for Mr Gibson's disappearance.
A girl, who was 16 years old at the time and cannot be named for legal reasons, will be sentenced for her involvement in Mr Gibson's murder later this month.
