There is absolutely no evidence on how they met their end. It is certainly possible that they were indeed killed, since both of them were the sons, and the eldest the sucessor of King Henry IV. It was their guardian Richard of York who had usurped the throne as Richard III. Richard had to face the very real possibility that as long as they lived they would be a rallying point for any rebellion against him.
Having them killed would solve that problem, of course. On the other hand, 50% of all children below the age of 14, royal or not, died prematurely from any of a great variety of childhood diseases, so dying of natural causes would certainly be possible as well. Finally, other stories tell of the princes being still alive long after they were supposed to have been killed. The bones of two children were found on the grounds of the Tower in the 17th century, but they haven't been DNA tested.
No
The two princes names were: Richard Duke of York, and Edward Vth
He would have been brother in law - married Elizabeth of York sister of the Princes
Whilst no one knows the truth with 100% certainty, it's suspected that Richard III had them killed to remove them from the line of succession (meaning he was the true heir to the throne).
Richard III didn't actually kill everyone. Athough there has been speculation that he killed his nephews (The Princes in the Tower) and his wife, as well as ministers and his subjects, there is not proof that he killed "everyone". Most of it was made up by the Tudors, who defeated Richard III in battle (Bosworth Field).
No
Although there is no absolute proof many historians believe that King Richard III was responsible for the deaths of the two princes in the Tower of London

why would Richard 3rd have the two princes murdered
Prince is still performing but has been having hip problems and sometimes must walk with a cane now, but other than that, he is still the performing Prince.
Shakespeare did not write a play called "Princes in the Tower". He did write a play called Richard III in which a couple of princes were murdered in the Tower, as well as another one called King John in which another prince dies trying to escape his would-be murderer.

Edward V son of Edward IV was taken to the tower along with his younger brother. Edward V was to be the King after Edward IVs death, but was declared illegitimate, therefore he could not be king. He and his brother were taken to the tower in fear of their safety after this news. They were under the care of their Uncle Richard Duke of Gloucester later Richard III. The princes were taken to the tower and never heard from again. The rumor is that either Richard III hired someone to smother them or Henry VII had them killed. It has never been proven who actually did it, both had reason to though. Later there were skeletons found in the tower believed to be those of the two princes.
Some people think they see the ghosts of the two princes but it remains a mystery.
