On 9 March 2008, it was announced that Australian archaeologists believed they had found Kelly's grave on the site of Pentridge Prison. The bones were uncovered at a mass grave and Kelly's are among those of 32 felons who had been executed by hanging. Jeremy Smith, a senior archaeologist with Heritage Victoria, said that "We believe we have conclusively found the burial site but that is very different from finding the remains". Ellen Hollow, Kelly's then 62-year-old grand-niece, offered to supply her own DNA to help identify Kelly's bones.
