In the lead-up to her violent death, a Sydney hairdresser known to friends as Nasrin Abek, 35, was allegedly stalked by her husband.
And on Wednesday he allegedly finally caught up with her and killed her inside their Potts Point unit.
Fairfax Media understands Amir Darbanou, 42, was growing increasingly angry with Ms Abek, and believed she had been unfaithful.
Ms Abek and Mr Darbanou were originally from Iran but had been living in Australia on bridging visas for the past four years, police said.
It is alleged that Ms Abek's father received a worrying phone call from Mr Darbanou on Wednesday.
Ms Abek's father then alerted police with concerns for his daughter's welfare.
On Thursday morning, police attended the couple's unit in St Neot Avenue, where they found Ms Abek's body with multiple stab wounds.
On Friday, Mr Darbanou appeared briefly before Central Local Court, charged with one count of murder.
He did not apply for bail and it was formally refused by magistrate Les Mabbott.
On Thursday, Kings Cross Superintendent Michael Fitzgerald said police had recovered what was possibly the weapon used to kill Ms Abek from the tip where the rubbish from the unit block was dumped.
"We are not looking at any other suspects in this matter," Superintendent Fitzgerald said.
"It is alleged that the son-in-law told [the father] certain things which brought the concern from the father to speak with police today."
Superintendent Fitzgerald also said there was no known history of domestic violence between the pair.
"Any incident of violence, let alone domestic violence, is tragic and we ask anyone if they've got any information about any loved one or any friend who may be involved in any domestic incident to come forward, to contact us, because we need to know."
Mr Darbanou is expected to face court again on November 24.
