The heartbroken girlfriend of slain university student Jamie Gao has flown back to her home in Japan to grieve with her family and friends.
Police will allege Mr Gao was shot dead by two former detectives, Glen McNamara and Roger Rogerson during a multimillion-dollar drug deal in Sydney's south-west on May 20.
His body was found a week later, wrapped in a blue tarpaulin and floating off the shores of Cronulla.
Mr Gao's devastated girlfriend Misaki Takebayashi and her close friends went to where his body was found two days later and threw flowers into the water.
She also threw a heart-shaped note into the ocean and posted a photo online of a necklace she had made with a pendant containing a photo of herself and Mr Gao.
Ms Takebayashi said she gone to the location to farewell her ''baby''.
The Japanese student used social media to speak of how much she loved Mr Gao and how he had always cared for her.
A close friend of the couple said Ms Takebayashi had flown home after friends farewelled Mr Gao at a private service in Sydney at the weekend.
The pair had been dating for a number of months. ''They were pretty close,'' said the friend, who did not wish to be named.
The night before the discovery of Mr Gao's body, Ms Takebayshi told friends she still hoped her boyfriend was safe and well.
In several posts she talked positively and said she knew he would be ''fine''.
But all of Ms Takebayashi's hopes were dashed when police charged Mr McNamara with murder and large-scale drug supply on Monday last week.
An hour and a half later, a fisherman found Mr Gao's body floating at sea.
The following day disgraced Mr Rogerson was arrested in dramatic style at his Padstow Heights home despite having arranged to hand himself into police later in the day.
Mr Gao, a business student at the University of Technology, Sydney, himself faced court one week before his death, charged with abducting a man in Sydney's south ''over a girl''.
In March he had been charged with two offences: taking and detain in company with intent to occasion actual bodily harm, and conspiracy to commit assault occasioning actual bodily harm.
He originally went before Kogarah Court, the same courtroom where one of his alleged killers, Mr McNamara, appeared last Monday.
The 20-year-old was on police bail.
Mr Rogerson and Mr McNamara were refused bail in their brief court appearances.
They are due to return to court in July.
