Accounts note that King Richard fought bravely and ably during this manoeuvre, unhorsing Sir John Cheyne, a well-known jousting champion, killing Henry's standard bearer Sir William Brandon and coming within a sword's length of Henry Tudor before being surrounded by Sir William Stanley's men and killed. The Burgundian chronicler Jean Molinet says that a Welshman struck the death-blow with a halberd while Richard's horse was stuck in the marshy ground. It was said that the blows were so violent that the king's helmet was driven into his skull. The contemporary Welsh poet Guto'r Glyn implies a leading Welsh Lancastrian, Rhys ap Thomas, or one of his men killed the king, writing that he "killed the boar, shaved his head". The identification in 2013 of King Richard's body shows that the skeleton had 11 wounds, eight of them to the skull, clearly inflicted in battle and suggesting he had lost his helmet. Professor Guy Rutty, from the University of Leicester, said: "The most likely injuries to have caused the king's death are the two to the inferior aspect of the skull—a large sharp force trauma possibly from a sword or staff weapon, such as a halberd or bill, and a penetrating injury from the tip of an edged weapon." The skull showed that a blade had hacked away part of the rear of the skull. Richard III was the last English king to be killed in battle. Henry Tudor succeeded Richard as King Henry VII. He married the Yorkist heiress Elizabeth of York, Edward IV's daughter and Richard III's niece.
On 4 February 2013, the University of Leicester confirmed that the skeleton was beyond reasonable doubt that of King Richard III. This conclusion was based on mitochondrial DNA evidence, soil analysis, and dental tests (there were some molars missing as a result of caries), as well as physical characteristics of the skeleton which are highly consistent with contemporary accounts of Richard's appearance. The team announced that the "arrowhead" discovered with the body was a Roman-era nail, probably disturbed when the body was first interred. However, there were numerous perimortem wounds on the body, and part of the skull had been sliced off with a bladed weapon; this would have caused rapid death. The team concluded that it is unlikely that the king was wearing a helmet in his last moments. Soil taken from the remains was found to contain microscopic roundworm eggs. Several eggs were found in samples taken from the pelvis, where the king's intestines were, but not from the skull and only very small numbers were identified in soil surrounding the grave. The findings suggest that the higher concentration of eggs in the pelvic area probably arose from a roundworm infection the king suffered in his life, rather than from human waste dumped in the area at a later date, researchers said. The mayor of Leicester announced that the king's skeleton would be re-interred at Leicester Cathedral in early 2014, but a judicial review of that decision delayed the reinterment for a year. A museum to Richard III was opened in July 2014 in the Victorian school buildings next to the Greyfriars grave site.
The proposal to have King Richard buried in Leicester attracted some controversy. Those who challenged the decision included fifteen "collateral [non-direct] descendants of Richard III", represented by the Plantagenet Alliance, who believed that the body should be reburied in York, as they claim the king wished. In August 2013, they filed a court case in order to contest Leicester's claim to re-inter the body within its cathedral, and propose the body be buried in York instead. However, Michael Ibsen, who gave the DNA sample that identified the king, gave his support to Leicester's claim to re-inter the body in their cathedral. On 20 August, a judge ruled that the opponents had the legal standing to contest his burial in Leicester Cathedral, despite a clause in the contract which had authorized the excavations requiring his burial there. He urged the parties, though, to settle out of court in order to "avoid embarking on the Wars of the Roses, Part Two". The Plantagenet Alliance, and the supporting fifteen collateral descendants, also faced the challenge that "Basic maths shows Richard, who had no surviving children but five siblings, could have millions of 'collateral' descendants" undermining the group's claim to represent "the only people who can speak on behalf of him". A ruling in May 2014 decreed that there are "no public law grounds for the Court interfering with the decisions in question". The remains were taken to Leicester Cathedral on 22 March 2015 and reinterred on 26 March.
On 5 February 2013 Professor Caroline Wilkinson of the University of Dundee conducted a facial reconstruction of Richard III, commissioned by the Richard III Society, based on 3D mappings of his skull. The face is described as "warm, young, earnest and rather serious". On 11 February 2014 the University of Leicester announced the project to sequence the entire genome of Richard III and one of his living relatives, Michael Ibsen, whose mitochondrial DNA confirmed the identification of the excavated remains. Richard III thus became the first ancient person of known historical identity whose genome has been sequenced. In 2016 contemporary British artist Alexander de Cadenet presented a skull portrait of Richard III in conjunction with Leicester University. The portraits have been produced using University of Leicester forensic X-ray scans of the king.
Richard's cathedral tomb was designed by the architects van Heyningen and Haward. The tombstone is deeply incised with a cross, and consists of a rectangular block of white Swaledale fossil stone, quarried in North Yorkshire. It sits on a low plinth made of dark Kilkenny marble, incised with Richard's name, dates and motto (Loyaulte me lie – loyalty binds me). The plinth also carries his coat of arms in pietra dura. The remains of Richard III are in a lead-lined inner casket, inside an outer English oak coffin crafted by Michael Ibsen, a direct descendant of Richard's sister Anne, and laid in a brick-lined vault below the floor, and below the plinth and tombstone. The original 2010 raised tomb design had been proposed by Langley's "Looking For Richard Project" and fully funded by members of the Richard III Society. The proposal was publicly launched by the Society on 13 February 2013 but rejected by Leicester Cathedral in favour of a memorial slab. However, following a public outcry, the Cathedral changed its position and on 18 July 2013 announced its agreement to give King Richard III a raised tomb monument.
