Police are still working to establish what led to the deaths of a man and a woman at a home on a suburban street in Brisbane's south.
The bodies of a 29-year-old woman and a 34-year-old man were found when officers were called to Redhead Street in Doolandella, about 15 kilometres south of the CBD, at 7pm yesterday.
Police said the man and woman had been known to each other but did not confirm their relationship.

Queensland Police Detective Inspector Michael Hogan said detectives spoke to several people in the street during the investigation last night.
"We're not looking for any other person that may have been involved in this incident," Hogan said.
"We are, however, continuing to ask anyone who may have knowledge and any information that may have addressed the investigation to come forward to police."
Two other men who live at the same property are assisting police with their enquiries.
It is understood the men were not home at the time.
"I can confirm they're not suspects and we're not considering that they had any involvement in the deaths," Hogan said.
"They've been very cooperative and they've assisted us greatly."
Police are investigating whether there was a history of domestic violence.
Detectives could not confirm whether the pair were married or in a relationship, or if a weapon was found at the scene.
Hogan said there were no children at the home at the time.
A heavy police presence has remained at the property today.
Neighbours in the street were left shocked by the news of the deaths.
"We're really wondering if it is such a safe neighbourhood," one neighbour said.
"When stuff like that is going on in your own street, it's a bit scary," another neighbour said.
Investigators are appealing to anyone who may have seen or heard anything in the vicinity of Redhead Street before 7pm yesterday to come forward.
They can contact police by calling 131 444.
