A man remains in an induced coma after falling from the fourth floor of an apartment complex following the death of his girlfriend in an alleged attempted murder-suicide in Sydney's south last month.
Police found the body of Liqun Pan, 19, in a unit in the complex on Brodie Sparks Drive, in Wolli Creek, on June 28, the day after they first attended the complex.
The injured man, 20, who is from China and on a student visa, was found seriously injured on June 27. Police believe he fell from a common area of the unit block onto the footpath.
He suffered multiple fractures and head injuries and was taken to St George Hospital. He remains in an induced coma and is yet to speak to police.
Ms Pan, also known as Pan Pan, had suffered significant injuries and police are treating her death as suspicious.
She was also on a student visa and was studying English at a language school in Elizabeth Street in Sydney's CBD.
She had lived in Australia for several years and had returned to China to visit her family about Christmas time.
Police are investigating links between her death and her boyfriend's fall.
St George Police Area Command crime manager Detective Inspector Robert Alison said her family was doing well, given the situation.
"It is horrific. I really do feel for the [Pan] family. The distance being so far away makes it even more difficult for them. But we are working closely with them."
Inspector Alison asked anyone who knew Ms Pan or had heard or noticed anything unusual before 3.25pm on June 27 to contact Crime Stoppers on 1800 333 000.
