If he had lived in Florida, it is unlikely he would have been referred to as the "Florida Beachcomber schizophrenic." As some have noted, there are wacked out people everywhere--they only become an interesting story if they murder some one or seem to fit a common, condescending, amusing and/or bizarre stereotype of some group of people, such as West Virginians or Ozarkians, African-Americans, schizoprhenics,etc.
And he probably is not schizophrenic either. He probably has brain damage from all that huffing!
