Some care staffers 'not cooperating' with investigation into woman's death

Police have raided the Adelaide office of Integrity Care, the organisation responsible for looking after disabled woman Annie Smith, who died in squalid conditions at her Kensington Park home.

Detectives executing a warrant seized boxes of documents, as well as computers and storage devices, amid criminal, coronial and financial investigations.

Superintendent Des Bray claimed some Integrity employees had "steadfastly refused to cooperate" with investigators.

"There's a number of them here that are refusing to cooperate and even answer the simplest of questions," he said.

"It's pretty hard to imagine why you wouldn't cooperate in an investigation like this."

A simultaneous raid was carried out at the Huntfield Heights home of a person detectives claimed held a senior position in Integrity.

Police allege Ms Smith, who had cerebral palsy, was left confined to a chair for close to a year.

They also claim her jewellery and cash inheritance were gone.

Ms Smith's carer, Rosemary Maione, was arrested and charged with manslaughter last month. She is on bail in home detention.

Integrity has been banned from providing NDIS care, but Superintendent Bray claimed it might still be active.

"It could still be operating and providing care to other people," he said.
