The two brothers were never seen again, and, in the meantime, Richard III claimed the crown in 1843 amid rumors that he had murdered the two boys. He was only able to enjoy being King for about two years, when he was killed in the Battle of Bosworth Field, in 1485. He was disrespectfully buried on the battlefield.
In the fullness of time, that battlefield was made a parking lot the bones were found. Extensive DNA research confirmed that the bones belonged to Richard III. As an added bonus, a life-sized plastic model of his face, was constructed from his skull.
Here's the burning question in my mind: Does this mean there is still hope for finding the bones of Jimmy Hoffa? I hope it won't take 500 years.
