Bones unlikely to be McCann's: police

The remains of a child found dumped in a suitcase in the South Australian bush are highly unlikely to be those of British girl Madeleine McCann, police say.

"There is absolutely no evidence at this point in time to suggest that the child concerned is Madeleine McCann," South Australian Police Commissioner Grant Stevens told reporters.

"We're prepared to consider any possibility but to suggest something like that at this point in time would purely be speculation for the benefit of getting attention."

Three-year-old Madeleine went missing from her holiday apartment in Portugal in 2007.

Some overseas websites have reported on the SA discovery, speculating whether the remains belonged to Madeleine.

SA police believe a fair-haired girl aged between two-and-a-half and four is the murder victim whose remains were found near Wynarka, in the Murray Mallee in the Riverland, earlier this month.

Detective Superintendent Des Bray previously said she could have died up to eight years ago.

When asked about whether the girl could be Western Australian child Lella McDougall, who went missing with her mother Chantelle in 2007, Commissioner Stevens said investigators were focused on South Australia.

"But we would be considering any missing child in terms of the match with what we have in the Riverland," he said.

Det Supt Bray said 410 reports had been made to Crime Stoppers, including 194 since Friday.

"We are extremely grateful for the level of community support we have received, and as a result of that support the investigation continues to progress each day," he said.

So far, 32 children have been excluded as potential victims.

Police on Monday issued a further digital image of part of a distinctive 90cm by 90cm homemade quilt found, along with girls' clothing, with the child's remains.
