What did john white seem to think happened to his fellow colonists?

John White believed that his fellow colonists had likely been killed or assimilated by local Native American tribes after he returned to Roanoke Island and found the settlement abandoned in 1590. He discovered the Word "Croatoan" carved into a post, which suggested they may have moved to a nearby island for safety or integration. White's theories were fueled by the absence of any signs of violence or struggle, leading him to speculate on both tragic and hopeful outcomes for the lost colonists. Ultimately, the fate of the "Lost Colony" remains a mystery.
