The inquiry recommended that the grave be found, the body exhumed, and its DNA compared to relatives of "Sydney" personnel. A 2001 search by the RAN failed to find the grave, but they were more successful during a second search in 2006. During an autopsy, a metal fragment was found embedded in the skull, which was believed to have killed the man through brain trauma: although seized upon by believers in the massacre of "Sydney"s sailors, the fragment was found to be German shell shrapnel. While DNA comparison testing did not produce definite results, as of September 2010 it remained on-going.
