Suspected human bones found on South Australian beach

Two bones believed to be human have been found on a South Australian Beach.

Police and SES volunteers are searching Maslin Beach, 40 kilometres south of Adelaide after what they think is a human forearm bone and a rib were found.

They are waiting for test results to confirm the bones are human, as they hunt for any other remains.

The arm bone was found on the sand by a man walking on Tuesday night.

He took it home and he contacted police after a relative suggested it could be human.

The next morning while searching the beach, officers found what they think is a human rib.

South Australian Police said they don't believe the find is suspicious, and think the bones are "relatively recent".

"We've worked with out partners are Forensic Science SA, and we suspect that that bone is a human bone which is relatively recent in the scheme of things, anything up to a coupe of months up to a year old," Detective Chief Inspector Scott Fitzgerald said.

"The bone was a forearm we believe.

"Police came down here yesterday and conducted a preliminary search.

"We located a second bone.

"That bone has also been examined by Forensic Science, and we believe that bone is also a human bone as well, being a rib."

Detective Chief Insp Fitzgerald believes the remains, if they are human, could be belong to a missing person.

Police are contacting families who might have reported somebody missing.

He admitted the find could be "gut wrenching for the families."

"Any loved one you don't know where they are, you don't know what's occurred to them would be anyone's living nightmare," he said.
