A pregnant mum of three found dead in Perth was likely murdered by someone she knew, police say.
Janet Dweh, 36, was found dead at a home on Mataro Drive in Dayton on Monday about 6pm.
Her death is being treated by WA Police as suspicious. Ms Dweh was eight months pregnant with her third child. Her unborn baby also died.
Superintendent Rod Wilde told reporters police believe someone Ms Dweh knew was responsible for her death and it was not a "random" person. He added it did not appear as if there was any forced entry into the home.
"We believe the person or persons that murdered Janet probably gained entry to the house through use of a key, or otherwise by Janet letting them into the house," he said.
"We believe Janet was probably murdered between the evening of Sunday or into the early hours of Monday."
Supt Wilde called it “a terrible, horrific event” with forensics likely to be on the scene into the weekend.
No one has been charged yet, he said. Supt Wilde said police will keep "an open mind".
"We have a number of lines of active investigation at this stage," he said.
"But as I say, no persons have been arrested or charged with any offence at this time."
Ms Dweh's three children are staying with family members. It's believed she was home alone at the time she was murdered.
A family member found her dead after they checked in on her in the home.
Supt Wilde was also asked if the person or persons responsible for killing Ms Dweh could face two charges as her unborn child also died, to which he said police would speak to the Director of Public Prosecutions for advice.
Ms Wilde’s friend Christopher Sunday began to cry as he told reporters how “wrong” it was that the mother had been killed.
“We all broke down with tears,” he said.
“Everybody falling on the street.”
Police wish to speak with anyone who witnessed “suspicious activity” in the street between 10am Saturday and 6pm Monday.
Anyone with information is asked to call Crime Stoppers on 1800 333 000 or to make a report online.
