Overall, I think everyone wants him punished, If he loses "something" all the better, he'd have to run, get medical care, would need a distraction to do it, depending on how it plays out even if he gets away it might make for a better story.
Then again, Ashley would still need to finish school as she hadnt finished at the point she was taken, which might lead to other problems so even without him there are a lot of things that could happen. She has been missing for atleast a week so the school would have enquired by this point.
Only Mr ZZ knows for sure...
