Rick Thorburn, 60, (pictured in 2016) is serving a life sentence for murdering Tiahleigh on October 29, 2015
It s been almost six years since three fishermen made a horrific find on the banks of the Pimpama River - the body of murdered schoolgirl Tialeigh Palmer.
The 12-year-old girl was naked except for a pair of underpants when her body was found on November 5, 2015.
Her tiny body was so badly decomposed, authorities have never been able to determine how she died.
Deputy State Coroner Jane Bentley is hoping to finally give Tialeigh s family answers during a two-day inquest starting on June 8.
The schoolgirl s foster father, Rick Thorburn, is serving a life sentence for murdering Tiahleigh on October 29, 2015.
