Homicide Squad detectives have charged a 23-year-old man with the murder of a 30-year-old woman in Perth's south on Friday.
Officers were called to a property on Henderson Road in Munster by St John Ambulance about midday on Friday and found the body of 30-year-old Cara Hales.
Shortly after, police said a man was "running around naked and appearing disoriented" in the neighbouring suburb of Henderson, near the intersection of Russell Road and Rockingham Road.
It is understood the man took off into bushland, but was later taken into custody.
Police have charged Jesse John de Beaux with the murder of Ms Hales. He appeared in court on Sunday and was not required to enter a plea.
Mr de Beaux stood with his hands in his pockets and was silent during his brief appearance, other than acknowledging his name and the charge against him.

Officers are still investigating whether the Wellard man was known to Ms Hales.
Ms Hales' death was the fourth suspicious death in WA in a three-day period.
