On the anniversary of Kelly's hanging, 11 November 2009, Tom Baxter handed the skull in his possession to police and it was historically and forensically tested along with the Pentridge remains. The skull was compared to a cast of the skull that had been stolen from the Old Melbourne Gaol in 1978 and proved to be a match. The skull was then compared to that in a newspaper photograph of worker Alex Talbot holding the skull recovered in 1929 which showed a close resemblance. Talbot was known to have taken a tooth from the skull as a souvenir and a media campaign to find the whereabouts of the tooth led to Talbot's grandson coming forward. The tooth was found to belong to the skull confirming it was indeed the skull recovered in 1929. In 2004, before the skull was handed to police, a cast of the skull was made and compared to the death masks of those executed at Old Melbourne Gaol which eliminated all but two. The two were those of Kelly and Ernest Knox, who had been executed in March 1894 (headstone marked E.K., 19–3–94) and buried near Frederick Deeming (headstone marked with the initials A.W. and a D underneath). In April 1929, the skulls of the E.K. marked grave (which was thought at the time to belong to Kelly) and Frederick Deeming were looted from the excavated graves. The death mask of Knox and a facial reconstruction of a cast of the skull were a close match.
