The situation is this, I have a boy who was abducted at age 4. At age 17, he comes to the attention of authorities for relatively benign reasons (vagrancy, concern for his welfare). He's uncertain about his real name, age---he gives it as a year younger---and he's evasive about where he's been and parts of his story are questionable. He doesn't appear to be a runaway; he expresses eagerness to be reunited with his "real" family whom he vaguely remembers. Under the circumstances, what steps would a rural/small-town law enforcement offical take at that point?
I have searched a variety of terms such as abduction, kidnapping, child-stealing, Stockholm syndrome, deprogramming; I know that the FBI database was in effect at the time of his disappearence AND that the file would have remained in the system indefinitely, unless removed. However, info on how they would go about to establish his identity is needed---because he's so much older, dental record wouldn't help, and he's unclear about his vital statistics. Would it be unreasonable for the locals to contact the FBI, and if so, what kind of Bureau response would they get? Would the Bureau be more concerned with getting information about the abductor, or with finding out who he is?
