Heaven knows where he & Elizabeth are. He'd have to have money wherever they are.
One thing, I feel better now about Ed's strange t.v. appearances, the letter, fax, e-mail, etc.
He could be a person of means, but maybe a loner? Maybe someone who has watched her at church or other venues, even making an overture to her that no one (she and her family) regarded at the time as being serious? I don't think he's very old, not older than 35 or 40. Maybe younger if this is not a true abduction.
I would hope LE is (has) checked all such sources.
