Oh, yes....the money....let's see, the Safra Will was changed shortly before his death. Let's see, who was the beneficiary? Oh, yes, the "poor widow" Lily, the very same who collected on her previous two husbands' deaths.
But, yes, let's assume the children have a motivation to sue, but Safra's widow had no motivation, whatsoever, to have her husband killed. I mean, the fact that NO INVESTIGATION into HER background must be "prima facie" evidence she's innocent (even though that's not what is done in any country where justice is sought). Gee, wilickers, that's kewl detective work there, by you and the Monaco po-lice.
