Rogerson threatened to kill girls: court

Seconds after Roger Rogerson shot Sydney student Jamie Gao over a botched drug deal he threatened to kill the daughters of his co-accused if he didn't help him move the body, a court has heard.

"I'll do you. Get up and help you weak c**t or you will be on the floor next to him," Glen McNamara said he was told as he gave evidence on Friday at the NSW Supreme Court, where he and Rogerson are on trial over the May 2014 murder of Mr Gao.

McNamara said he was "terrified" and "stunned" as Rogerson repeated his demand for help, threatening "otherwise I'll kill your girls," the court heard.

The crown case is the two men, who accuse each other of killing Mr Gao, shot the alleged drug dealer before stuffing his body into a surfboard bag and dumping it at sea.
