That's just it - I think it would take a little more ingenuity like some of those intredid detectives on TV. Seriously though - the perpetrators evidently were very careless and sloppy about the passenger lists, death records, and all. I'm pretty sure somebody could shake some interesting revelations if they had the time and the hutzpah to investigate on the ground, first person. Oh well, it's not me though, I live in Mexico.
