the time of death. The analysis also identified multiple rib fractures, but it is unknown whether these occurred around the time of death or long after death with the settling of the grave. No other shrapnel or projectiles have been found elsewhere in the remains. The fragment was found embedded in the man's skull during an autopsy in 2006. Anatomical analysis indicated that the unknown sailor was aged between 22 and 31 when he died, was right-handed, had size 11 feet and was tall for his generation, between . Bone isotope analysis showed that he had lived in eastern Australia, probably New South Wales or Queensland, before enlistment and may have grown up on the coast. The unknown sailor had acquired an unusual feature in both ankle joints, known as squatting facets; these indicated that he was more used to squatting than sitting on chairs. As squatting was unusual at the time in urban, western communities, it was speculated that the man had spent significant time in a rural area of Australia; amongst members of an ethnic group in which squatting was more common than sitting (such as people from Asia or Eastern Europe) and/or involved in a sporting or similar activity that required the ankles to be flexed towards the back of the thighs for prolonged periods. Attempts to extract a DNA profile from the remains began around 2009, although the results were not published before the Cole Inquiry. Analysis of the partial genetic profile recovered has since suggested that the man had red hair, blue eyes and pale skin, and was likely of Irish or Scottish descent. He belonged to a mitochondrial haplogroup (i.e. an ancient matrilineal line of descent) known as haplogroup J1c12. This relatively rare haplogroup has most often been found in people with matrilineal ancestors from various parts of Europe, the Caucasus or Middle East. The boilersuit and shoe found with the body were, according to evidence provided by the Australian War Memorial, available to ship's officers, commissioned warrant officers and warrant officers senior enough to have a watch keeping certificate. Tests on the remains of the boilersuit showed that the fabric had never been dyed, was probably white and the press studs were of a type manufactured by Carr Australia Pty Ltd in the 1930s and 1940s. RAN Dress Regulations published in the Navy List of December 1940 do not mention white boilersuits. There
