some left last minute. many left after. some may have been swept out to sea. they gone door to door of the homes left to look for people and bodies. last i heard, Galveston has been pretty well checked over and cleared out. no power and no resources forced most to leave after the storm if they survived.
as for those who may have been washed away, we may never know of some of them. others will come to light as families start to search for them.
