On 12 September 2012, the
University of Leicester team announced that the human remains were a possible candidate for Richard's body, but emphasised the need for caution. The positive indicators were that the body was of an adult male; it was buried beneath the choir of the church; it had severe
scoliosis of the spine, possibly making one shoulder higher than the other. An object that appeared to be an arrowhead was found under the spine and the skull had severe injuries.
DNA evidence After the exhumation the emphasis shifted from the excavation to laboratory analysis of the bones. Ashdown-Hill had used
genealogical research to track down matrilineal descendants of
Anne of York, Richard's older sister, whose matrilineal line of descent is extant through her daughter
Anne St Leger. Academic
Kevin Schürer subsequently traced a second individual in the same line. Ashdown-Hill's research came about as a result of a challenge in 2003 to provide a
DNA sequence for Richard's sister
Margaret, to identify bones found in her burial place, the Franciscan priory church in
Mechelen, Belgium. He tried to extract a
mitochondrial DNA sequence from a preserved hair from
Edward IV held by the
Ashmolean Museum in
Oxford, but the attempt proved unsuccessful, owing to degradation of the DNA. Ashdown-Hill turned instead to genealogical research to identify an all-female-line descendant of
Cecily Neville, Richard's mother. After two years, he found that a British-born woman who had emigrated to Canada
after World War II, Joy Ibsen (), was a direct descendant of Richard's sister, Anne of York, and therefore Richard's 16th generation great-niece. Ibsen's mitochondrial DNA was tested and found to belong to
mitochondrial DNA Haplogroup J, which by deduction should be Richard's mitochondrial DNA
haplogroup. The mtDNA obtained from Ibsen showed that the Mechelen bones were not those of Margaret. Joy Ibsen, a retired journalist, died in 2008, leaving three children: Michael, Jeff, and Leslie. On 24 August 2012, her son Michael (born in Canada in 1957, a cabinet maker residing in London, England) gave a mouth-swab sample to the research team to compare with samples from the human remains found at the excavation. Analysts found a mitochondrial DNA match among the exhumed skeleton, Michael Ibsen, and a second direct maternal line descendant, who shares a relatively rare mitochondrial DNA sequence, haplogroup J1c2c. One other living female-line relative of Richard III is Wendy Duldig, an Australian resident in England and a 19th generation descendant of Anne of York. Duldig, who has no surviving children, is connected to the Ibsen family through Anne's granddaughter
Catherine Constable (née Manners). Descendants of Constable, including one of Duldig's ancestors, reportedly emigrated to New Zealand. Duldig's mitochondrial DNA is reportedly a close match, i.e., it features one mutation. Langley rebuts Hicks's argument on the grounds that he does not take into account all the circumstantial evidence. The University of Leicester also responded to Hicks's criticism:
Bones An
osteological examination of the bones showed them to be in generally good condition and largely complete except for the missing feet, which may have been destroyed by Victorian building work. It was immediately apparent that the body had suffered major injuries, and further evidence of wounds was found as the skeleton was cleaned. Elsewhere on the skull, a blow from a pointed weapon had penetrated the crown of the head. Bladed weapons had clipped the skull and sheared off layers of bone, without penetrating it. Other holes in the skull and lower jaw were found to be consistent with dagger wounds to the chin and cheek. The multiple wounds on the skull indicated that the man was not wearing his helmet at the time, which he may have either removed or lost when he was on foot after
his horse had become stuck in the marsh. One of his right ribs had been cut by a sharp implement, as had the pelvis. There was no evidence of the withered arm that afflicted the character in
William Shakespeare's play
Richard III. Taken together, the injuries appear to be a combination of battle wounds, which were the cause of death, followed by post-mortem
humiliation wounds inflicted on the corpse. The body wounds show that the corpse had been stripped of its armour, as the stabbed torso would have been protected by a backplate and the pelvis would have been protected by armour. The wounds were made from behind on the back and buttocks while they were exposed to the elements, consistent with the contemporary descriptions of Richard's naked body being tied across a horse with the legs and arms dangling down on either side. The head wounds are consistent with the narrative of a 1485 poem by
Guto'r Glyn in which a Welsh knight,
Rhys ap Thomas, killed Richard and "shaved the boar's head". Other contemporary sources refer explicitly to head injuries and the weapons used to kill Richard; the French chronicler
Jean Molinet wrote that "one of the Welshmen then came after him, and struck him dead with a
halberd", and the
Ballad of Lady Bessie recorded that "they struck his
bascinet to his head until his brains came out with blood". Such accounts would certainly fit the damage inflicted on the skull. Sideways curvature of the spine was evident as the skeleton was excavated. It has been attributed to adolescent-onset
scoliosis. Although it was probably visible in making his right shoulder higher than the left and reducing his apparent height, it did not preclude an active lifestyle, and would not have caused what modern medicine describes as a "
hunchback". The bones are those of a male with an age range estimation of 30–34, and 1412–1449—both too early for Richard's death in 1485.
Mass spectrometry carried out on the bones found evidence of much
seafood consumption, which is known to
make radiocarbon dating samples appear older than they are. A
Bayesian analysis suggested there was a 68.2% probability that the true date of the bones was between 1475 and 1530, rising to 95.4% for 1450–1540. Although by itself not enough to prove that the skeleton was Richard's, it was consistent with the date of his death. The mass spectrometry result indicating the rich seafood diet was confirmed by a chemical
isotope analysis of two teeth, a femur, and a rib. From the isotope analysis of carbon, nitrogen, and oxygen in the teeth and bones, the researchers discovered the diet included much freshwater fish and exotic birds such as
swan,
crane, and
heron, and a vast quantity of wine—all items at the high end of the luxury market. Close analysis of the soil immediately below the skeleton revealed that the man had been infested with
roundworm parasites when he died. The excavators found an iron object under the skeleton's vertebrae and speculated it might be an arrowhead that had been embedded in its back. An
X-ray analysis showed it was a nail, probably dating to
Roman Britain, that had been in the ground by chance immediately under the grave, or was in soil disturbed when the grave was dug, and had nothing to do with the body. ==Identification of Richard III and other findings==
