Police have now released further information about the human bones which were found in sand hills near Nora Creina almost a year ago.

Officers have confirmed earlier capital city news media reports the bones found last October belong to an adolescent of undetermined stature.

A member of the public found the bones and they have since been taken to laboratories in Adelaide and Canberra for further scrutiny by anthropologists.

There are no signs of violence on the human remains and there is nothing obvious to say the death is suspicious.

South Australia Police’s Operation Persevere was established to provide a structured and consistent approach to the management, investigation and review of long-term missing persons and unidentified human remains.

Since March 2019 Operation Persevere has successfully identified 10 unidentified human remains.

As part of the current nationwide Missing Persons Week, police have publicised 18 cases of unidentified human remains including the Nora Creina bones and another matter from Port MacDonnell dating back to 2004.

On February 8 of that year, a single bone fragment which is presumed to be a humerus (upper arm bone) with a 70mm metal surgical plate attached, was located on Woolwash Beach.

An anthropological examination suggests the bone is from a young adult.

As with the Nora Creina bones, it has yet to be determined if the remains are from a man or woman.

The only markings on the surgical plate are ‘Vitallium’.

Enquiries have revealed this was a commonly used surgical bone plate, to repair fractures.

Vitallium is an alloy of cobalt and chromium which was widely used for surgical instruments and prostheses.

Assistance is sought by police for any information regarding this individual or from anyone who knew someone one who had a surgical plate inserted into their upper arm and is now missing.
