I don`t know about the Edwards millions, but I know of several VERY WEALTHY people who have died with no known heirs. This has been kindly pointed out to me be many Bank Officials/Lawyers/Benefactors etc. - sometimes around Fifty Million Dollars is involved and all I have to do is turn up and claim to be a relative and they will do the rest!
Unfortunately, I am unable to travel at the moment, but for a small consideration I will put you in touch so that you can claim.
