Water Police divers are today searching the Swan River, near the Fremantle Traffic Bridge, as part of the ongoing investigation into the death of Annabelle Chen.
Ms Chen, 57, was identified last week as the woman whose body was discovered in a suitcase in the Swan River in July.
Police confirmed her identity after conducting a search at a Mosman Park property last week.
