Two men and a woman have been charged with the alleged murder of a mother-of-six in Byford.
Nardia Louise Spice was allegedly lured to a dog park by her housemates and murdered between 3am and 5am on September 23.
Police allege the 40-year-old died from "blunt force trauma" to the head with detectives seizing both "tools and weapons" as part of their investigation.
It is alleged her body was then moved by car and buried in bushland off Ronan Road in Jarrahdale.
"A body believed to be Nardia's was later located by police in the Jarrahdale area on the 7th October," Detective Sergeant Sam Hazlitt said.
Detective Hazlitt said the four people charged and Ms Spice were housemates who lived a “transient” lifestyle.
Ms Spice had six children and a foster child who she was not living with at the time.
A 32-year-old man and a 30-year-old woman both from Brookdale have been charged with murder.
A 24-year-old man from Armadale has also been charged with murder, while a 26-year-old man from Armadale has been charged with accessory after the fact to an indictable offence.
