This is Yeng Jun Wu - a bankrupt businessman who was jailed for 27 years after brutally murdering his brother-in-law and removing his brain.

Supreme Court Justice Terry Forrest said that in his 35 years in criminal law he had never seen a crime as "appallingly and gratuitously violent".

Justice Forrest said Yeng Jun Wu's torture and execution of his brother-in-law Shao Qing 'Victor' Chen and the subsequent defiling of his body were aggravating factors of his offending.

Mr Chen had most likely been asleep when Wu, who owed him more than $250,000, set upon him in his bedroom with a heavy, sharp weapon believed to be a machete or an axe.
