Recent archaeological finds on America's East Coast appear to have pinpointed remains of Roanoke settlers who apparently split up and secretly moved the colony to 2 new locations, thereby avoiding a Spanish fleet sent to destroy them. The Coast Guard has started a search among North Carolina's offshore islands, even though investigators believe it would be hard to hide a population much larger than Roanoke's there, and that the M.I.A. "It's as if they vanished without a single trace". The USPS also announced they had ceased covering the territory due to "operational difficulties". As a CNN exec explained it, "we know they're within our coverage area, but without proper demographics, it's as if they don't even exist."
