 Many of the bones had been broken by the original workmen.The examination has been criticised, on the grounds that it was conducted under the presumption that the bones were those of the princes and concentrated only on whether the bones showed evidence of suffocation; no attempt was even made to determine whether the bones were male or female.No further scientific examination has since been conducted on the bones, which remain in Westminster Abbey, and DNA analysis (if DNA could be obtained) has not been attempted.
