Answer:
The colonists mysteriously vanished by the time Walter Raleigh's crew arrived back on Roanoke.
Explanation:
When Walter Raleigh returned from England, the colony was completely gone except for two signs; Croatoan etched into a fortress and Cro marked on a tree. Theories on what's happened have ranged from the colonists running out of resources and joining the Croatoan tribes on Hatteras Island; to them all just dying out. Hope that helps!
