Forensic pathologists also examined the bones from Pentridge, which were much decayed and jumbled with the remains of others, making identification difficult. The collar bone was found to be the only bone that had survived in all the skeletons and these were all DNA tested against that of Leigh Oliver. A match to Kelly was found and the associated skeleton turned out to be one of the most complete. Kelly's remains were additionally identified by partially healed right foot, right knee and left elbow injuries matching those caused by the bullet wounds at Glenrowan as recorded by the gaol's surgeon in 1880 and by the fact that his head was missing, likely removed for phrenological study. A section from the back of a skull (the occipital) was recovered from the grave that bore saw cuts that matched those present on several neck vertebrae indicating that the skull section belonged to the skeleton and that an illegal dissection had been performed.
