Court documents show Schiebel and her co-accused Bunney allegedly used fencing wire to strangle and restrain their victim while torturing him over a three day period.

It will be alleged they then used an illegal shotgun to shoot him.

Both Scheibel and Bunney will next appear in Caboolture Magistrates court in July.
