A grieving community will gather to mourn the loss of a young Chinese woman as police try to work out what led up to her fatal stabbing and the death of another student.

The body of the woman, identified as 21-year-old Xiaoting Wang, was found with multiple wounds inside an apartment in the inner-west Sydney suburb of Burwood on the morning of August 12.

NSW Police officers had earlier been called to the building for a welfare check and found the body of a 21-year-old male student from China in the courtyard.

CCTV footage showed Wang walking into a unit, but investigators previously said they were unsure whether she had been living there.

The man had ankle injuries and it was possible he had jumped from a higher level.

But it was too early to say if the pair were in a relationship or if the deaths were a domestic-related murder-suicide, police have said.

A vigil for Wang, a Sydney University student, will be held at Burwood Park Pavilion from 5pm on Tuesday.

NSW Police local commander Christine McDonald said many people in the community and elsewhere in Sydney had been affected by the young woman’s death.

“She, like many international students, came to this country for education and opportunity, and for her life to end like this is tragic,” Detective Superintendent McDonald said on Wednesday.

“I urge anyone affected by the deaths to attend a vigil … to support each other through this time.”

A strike force involving local detectives and Homicide Squad officers has been set up to investigate the deaths and police are calling for anyone with information about the incident to come forward.

Sydney University vice-chancellor Mark Scott wrote to staff and students at the time of the deaths, saying the university was co-operating with police.

“This is unsettling news for our community … I encourage you to reach out for support if you need it,” his message said.
