Princes in the Tower household which stated: "the children should be together at one breakfast". James Gairdner, however, argues that it is unclear to whom the phrase "the children" alludes, and that it may not have been a reference to the princes. It may refer to Edward, Earl of Warwick (son of the Duke of Clarence) and Edward IV's two youngest daughters (Catherine and Bridget), all of whom were living under Richard's care at Sheriff Hutton. Other than their disappearance, there is no direct evidence that the princes were murdered, and "no reliable, well-informed, independent or impartial sources" for the associated events.

Princes in the Tower Richard took the throne for himself and the boys disappeared. It is unclear what happened to the boys after they disappeared in the Tower. It is generally assumed that they were murdered; a common hypothesis is that they were killed by Richard in an attempt to secure his hold on the throne. Their deaths may have occurred some time in 1483, but apart from their disappearance, the only evidence is circumstantial. As a result, several other hypotheses about their fates have been proposed, including the suggestion that they were murdered by Henry Stafford, 2nd Duke of Buckingham or Henry VII,
