Who killed the princes in the tower

Edward V and his younger brother Richard, were sent to the Tower by Richard Ill( withal their uncle). the boys were declared illegitimate and the Duke was coronate King Richard Ill. Then the Princes vanished Richard Ill has usually been considered the most likely culprit. By declaring the princes illegitimate, he cleared his way to the throne. He would secure his position by having them murdered. In 1485, Richard Ill was killed in the Battle of Bosworth.The defeater, Henry Tudor, was crowned King Henry VI. It was in the Tudors interest to paint Richard as a villain. Henry VII is in any case a suspect. He married the princes sister, Elizabeth of York, strengthening his claim to the throne. This could have been jeopardised if the boys had survived. It does seem unlikely that they survived beyond the end of Richards reign without being seen. There are also other suspects including the Duke of Buckingham, once Richards closest ally, whom he later had beheaded.Thomas More, writing over 30 years later, stated that the princes were mothered on their uncles orders, secretly buried at the stair foot, and then reburied elsewhere in the Tower. Two skeletons, identified as those of the princes, were discovered when a building in front of the White Tower was demolished in 1674. The skeletons were examined in 1933 and pronounced as belonging to two boys, aged about ten and twelve. Were these the two boys? I think that king Richard Ill killed the two boys, precisely then again How could a man who seems to be so fiercely loyal to his brother, kill his brothers children after his death?Despite having eliminated the two princes from being in line for the throne, his claim to the throne was still insecure and the Princes could be a threat all the time they were alive. Richards enemies would seize on them as a attracter without real power and Richard couldnt afford that. Despite the rumours and accusations of murder, Richard never attempted to prove them alive by having them seen in public nor did he open any investigating into an investigation into the matter. This to me seems very suspicious and therefore that is why I am convinced Richard Ill killed the princes in the tower.
