A man accused of killing his American girlfriend and burying her body in a backyard trench before later disposing of it at a rubbish tip has been found guilty of murder.
Mark Sheridan Waden was charged after the disappearance of Priscilla Brooten, a 46-year-old US citizen who was living in Australia without a valid visa.
The 50-year-old was found guilty by a jury on Tuesday after weeks on trial in Brisbane Supreme Court. He faces a mandatory life sentence.
