I can't think of any angle he can got to revive himself, best he just takes whatever money he has and goes away and enjoys the rest of his life.
I'm still curious of what he will be convicted of if he is. Like you said the major accusations are hard to prove, how can you prove 20yo rape case? Maybe they can prove the sex trafficking aka flying in hookers for sex and flying with the pink MDMA. But does that deserve 10-20 years in jail?
