A bone found at a beach south of Adelaide belonged to missing person Jesse Corigliano-Quealey, South Australia Police say.
The bone was found by a member of the public walking along Maslin Beach, about 40 kilometres south of Adelaide, on February 16.
It was handed in to police the following morning and has since been examined by forensic investigators.
SA Police said DNA confirmed it belonged to 30-year-old Mr Corigliano-Quealey, who went missing from Maslin Beach on October 9.
Police said his death was not considered suspicious, and that his family have been notified.
A report is being prepared for the state coroner.
Last week, police said the discovery had prompted investigators to reopen several cold cases relating to missing persons.
"There are many people over the years that go missing for a variety of reasons," Detective Chief Inspector Scott Fitzgerald said.
He said the bone was believed to be a human forearm.
The discovery of the bone prompted emergency services to search the area around Maslin and Moana beaches for several days last week.
During that search, a second bone was discovered about 50 metres from the first one.
Police believe that to be a rib, but it is still being examined at Forensic Science SA.
Missing persons advocacy group Leave a Light On has expressed its "sincerest condolences" to "Jesse's family and friends at this time".
"Despite numerous appeals by police, his family and missing persons organisations, Jesse could not be located," the group wrote on Facebook.
