A suspect remains on the loose after a Brisbane mother was killed in her home as her daughters slept.
The 34-year-old woman was found dead in the lounge room by a male housemate after she received a late night visit from a man, described by police as a friend.
Two of the woman's daughters, aged 11 and 12, were sleeping in the house where they lived.
The nature of the woman's injuries was not revealed, but police said no weapon was involved.
Police are searching for a man in his 30s who visited her home at Norman Park, in Brisbane's inner east, during the early hours of Tuesday morning.
Detective Inspector Rod Kemp described him as a friend of the victim.
"He could've been there around 2am," Det Insp Kemp told reporters.
"All I can say is he's known to the person. He's been there before."
Police do not believe he was an ex-partner.
It was unclear if the man left the Milsom Street home on foot, in a car, or by train at the nearby Norman Park railway station.
Attempts by paramedics to revive the woman were unsuccessful.
The woman's two housemates, who did not hear anything, are co-operating with police, as they appeal for public information.
"There was no noises as such, no extreme violence evident," he said.
Insp Kemp was unable to say if the victim had been sexually assaulted.
The woman's daughters were receiving counselling as forensic experts combed the property on Tuesday morning.
A third daughter, aged 15, lives with her grandmother.
"Horrendous. It's their mother. Absolutely horrendous," Insp Kemp said.
The woman's body was removed from the home on Tuesday afternoon.
The property was sealed off with police tape as officers interviewed neighbours.
