After six and a half days of deliberation, the jury delivered their verdicts – guilty for both men on charges of murder and taking part in the supply of 2.78 kilograms of ice, SMH reports.
However, throughout the hearing, the two did not stick to the same story, both blaming each other for Mr Gao’s death.
Gao, 20, was lured by the two to a Sydney storage shed on a May afternoon where they then shot him.
His body was then dumped at sea before being spotted off the shore of Cronulla in Sydney’s south.
