I think that it isn't that hard to liquidate.. . lots of cash can buy things that are ostensibly the organizations, but which are portable and easily disposed of (gold, jewelry, cash). If there are accounts overseas of investments, or even here, if they get it out, put in into cash and leave, they are guilty, but easily out of reach of anyone who would go after them for it. Someone would have to clean up the mess. . . but it wouldn't be THEM.
There is a possibility that years ago I read too much John Grisham, but I don't think this stuff is rocket science.
