According to Nine News Perth’s Mia Egerton-Warburton, Ms Cheruiyot’s body was moved from the scene overnight and forensic officers remained at the property throughout the evening and through to Thursday morning.
The homicide squad also arrived at the scene on Thursday and later confirmed the woman’s death was being investigated as a suspected homicide.
«A forensic examination has identified that there are injuries to the deceased and as a result of those injuries we have declared that this is a homicide investigation,» Senior Sergeant Wright said.
Neighbours said they had often heard people arguing and police had made visits to the Main Street unit before Wednesday’s discovery.
Police are still attempting to track Ms Cheruiyot’s last known movements, and notify her extended family.
Ms Cheruiyot’s social media indicates she is originally from Kenya, but had two family members based in Perth.
«We’re trying to put an exact time on the last time she has been seen,» Senior Sergeant Wright said.
«It’s part of our investigation to speak to any person that has seen her, including people from work. It appears at this stage it could be as long as seven days.»
Police have indicated they are also trying to locate two cars linked with the Main Street address which had not been seen in some time.
«They are of particular interest to us,» Senior Sergeant Wright said.
«We would ask any person that sees these vehicles to contact Crime Stoppers so we can see the vehicle and do an examination if required.»
One car is a blue 2007 Hyundai Getz hatchback, registration 1CMR900. The other is a blue 1995 Mitsubishi Coupe, registration 1BJP872.
Police declined to comment on whether Ms Cheruiyot’s family became concerned after she missed a planned flight to the US on May 22, and the state of the crime scene.
«We would certainly like answers as soon as possible. It’s a timely process,» Senior Sergeant Wright said.
«We will leave no stone unturned – you’ve heard all those cliches before. We’re doing everything we possibly can from a forensic point of view to assist us with identifying exactly what’s happened inside the premises.»
