Characters Who Need to Fake Their Own Death

Create such a character. Who are they? What is their history, what brought them to this point where they must fake their own death? WHY are they doing this? What do they hope to gain? How do they go about it? What are they going to do that will absolutely convince family, friends, employer, coworkers, community, AND the authorities that they are dead and gone? Or is one or more of those groups in on the scheme? WHY? Details, details... we want details... "The Running Man," starring Laurence Harvey and Lee Remick was one of my favorite "faked death" movies.
