Child's bones found in SA remain a mystery

The identity of a child whose remains were dumped in a suitcase in the South Australian bush is still unknown, despite police receiving 200 calls from the public.

They have now ruled out 20 potential victims.

The gender of the child, believed to be aged between two and five, has not yet been determined.

A driver reported finding the remains near Wynarka, in the state's southeast, on July 15.

The suitcase had been in the scrub for months and police believe a number of people may have gone through its contents, which included girl's clothing.

Police say more people have come forward reporting sightings of a man, aged around 60, carrying a suitcase in the area before the remains were discovered.
