"It saddens me that you would be involved in this" (or words to that effect) doesn't tell me she knew anything. I don't doubt that the police would be checking into her history etc.
I'm wondering if woman are generally involved in pedo rings? Seems to me that the wives and partners of these creeps would have to have some idea of what's going on and I think the txt sent by MS shows she at least knew of the allegations from 27 years ago.
