I did not think it would be easy - but I do have a long history of assisting the FBI with finding people with these sorts of personality disorders. I can offer you my services, and the services of some good friends of mine. We should be able to get you closer by sharing what we know about this sort of mental illness - not to mention being able to track this person down afterwards.
