The murder of the Princes in the Tower
Unfortunately for the two boys, Gloucester had his own plans of becoming king and mysteriously the two boys disappeared, supposedly murdered in the Tower. Although it has never been proven, it is suspected that Gloucester had the two boys killed so he could become the king as Richard III.
In 1674 the bodies of two children were found within one of the towers. Unidentified, the bodies were reburied in Westminster Abbey.
