A man has been arrested over the murder of 85-year-old grandmother Liselotte Watson in Queensland last year.
No charges have been laid, but police say they will release more information later on Thursday.
Ms Watson was found by police face down in a bedroom of her home on Macleay Island, off Brisbane, last November.
A member of the public found some of her belongings at Thompson's Point at the other end of the island, days after her body was discovered, before police divers found more items in the water.
Police would not reveal what the items were, but said the fact they were taken from the murder scene indicated foul play.
