Very unlikely to be the case, but here is the Federal Witness Protection Program's history and its procedures:
In the United States, the Witness Protection Program...was established under Title V of the Organized Crime Control Act of 1970, which in turn sets out the manner in which the United States Attorney General may provide for the relocation and protection of a witness or potential witness of the federal or state government in an official proceeding concerning organized crime or other serious offenses.
...
The Federal Government also gives grants to the states to enable them to provide similar services.
...
Normally, the witness is given a new name and location. Witnesses are encouraged to keep their first names and choose last names with the same initial, in order to make it easier to instinctively use the new identity. The U.S. Marshals Service provides new documentation, assists in finding housing and employment and provides a stipend until the witness gets on his or her feet (...) Witnesses are not allowed to travel back to their hometowns or contact unprotected family members or former associates. In order to do everything possible to preclude the possibility of the witness being followed, the witness is made to adhere to a convoluted and indirect transportation path before finally reaching the location where they will live under the new identity.

If this were the (very unlikely) case, the Arkansas location motif might be a further cover.
