The unknown woman whose body was found in a suitcase dumped in the Swan River last week suffered a violent death, with police revealing she had significant injuries.
Detectives trying to solve the mystery of the Asian woman's identify and how she died released new details to try to get someone to come forward with information.
They believe she was dumped in the river near the Fremantle traffic bridge some time after Monday, June 27 before she was found nearby by two fishermen on July 2.
Divers are searching in that area after a woman contacted police when she spotted tiles there this week that matched those in the suitcase, presumably to weigh it down.
The woman, who police think was aged between 35 and 45, was 160cm tall and weighed 59kg with a red shade in her hair and was wearing a distinctive Tokyo Disneyland T-shirt.

She had tattooed eyebrows and dental work including a crown on her top front left tooth that made it lighter than the rest of her teeth.
Police have received more than 250 calls from the public, including possible names, and have released a computer image but are yet to identify her and whether or not she was Australian.
"She will be someone's daughter, someone will know her and care for her and miss her," Detective Sergeant Mat Atkinson told reporters.
"The circumstances surrounding the disposal of the body are terrible and for these reasons we are committed to finding answers."
Police were reaching out to interstate and international law enforcement and would also be contacting the immigration department and Asian communities in Perth.
Det Sgt Atkinson said the area around the Fremantle bridge was popular for fishing and urged anyone who saw anything unusual to come forward.
