Police allege that former detectives planned to kill Sydney student Jamie Gao so they could steal $3 million worth of the drug ice.

New details have emerged which suggest that former police officers Roger Rogerson and Glen McNamara had planned to execute Gao.

“It’s the belief of most involved that it was planned,” said a police officer who did not want to be named.

The body of the 20-year-old student was found stuffed inside a surfboard bag floating off Cronulla with two gunshot wounds to the chest.

Court documents will allege that the men brought a gun and a silver surfboard bag along to their meeting with Gao.

CCTV footage shows the three men walking into a Rent a Space storage unit and only Rogerson and McNamara leaving with the bag between them.

Police officers are allegedly stunned at the choice of a storage facility as the murder location because it is covered with security cameras.

“It was so dumb,” one detective told the Sydney Morning Herald.

New details reveal that two Asian men were in the car with Gao when he arrived to meet Rogerson and McNamara.

Police are trying to identify these men and also who was responsible for shooting Gao.

“There’s still a lot of work to do,” admitted police working on the case.
