$8M in bank/investment accounts among DA, HA, CA, and WA, CA and WA had "only" $550K each of that but it doesn't include cash kept in safes, or non-liquid assets like real-estate.
After the CA verdict, I figured the Markels would be getting solicited by civil attorneys, looking to get a piece of whatever is left of the Adelson empire. I don't even think they would have to sit in such a trial if they didn't want to. Going after the Adelson assets would be a defeat to WA (if she remains free) who could have lived comfortably off them. The Markels could use the settlement to take care of the grandsons under their own terms, too, and not DA's trusts that she supposedly set up.
