Homicide Squad detectives investigating the suspicious disappearance of a 32-year-old Perth woman are questioning a man she knows and digging up a backyard.
Police cordoned off a house on Weston Street in Carlisle on Wednesday morning while they interviewed the 36-year-old man and searched the property, including digging in the rear garden.
They say the woman was reported missing on Tuesday.
The forensic examination of the home continues.
Neighbours have told reporters a family of four lived at the property, while a carpet cleaner who arrived at the crime scene said he had been booked on Tuesday to work there.
