Many times you'll find someone with a background in one of the many non-LDS Mormon groups who wends his way into an isolated stake, and next thing you know he's sold millions of dollars of life and casualty insurance ~ and then he/she disappears!
Other times it's one of the fellows from the older (circa 1702 for post Scandinavian appearances) congregations flying under the name Church of the First born. (NOTE: do not rely on the SPLC definitions of these groups ~ they are so wrong on so many counts it's unbelievable ~ they want to restrict the non-Mormon related COTFB to just the 19th century Laestidians ~ which is bizarre).
Some COTFB frauds against LDS folks have been limited to the standard bad-insurance deal. Others are more serious. Warren Jeffs' family come to mind as probable COTFB types who moved in on some isolated but otherwise wealthy independent non-LDS Mormons and turned them into a regular gravy train for the Jeffs and a couple of other families under the title FLDS.
That deal was the rough equivalent of how Mr. Howell, calling himself "David Koresh" took over a small SDA (Seventh Day Adventist) denomination ~ one of his grandmothers claimed COTFB affiliation in the Tulsa area, and he endedup being taken out of business by Bill Clinton whose baby daddy was a member of another COTFB group in Arkansas (which gives you some links to REAL Gypsies and REAL traditional scams).
Wow.
