re: I may regret this....but how, exactly?
Regardless of whether he kidnapped the kid, or killed her, or just goes to prison for the parole violation he was hauled in for, for the foreseeable future I'm going to be able to find out exactly where he lives, along with the large number of sociopathic dregs who will live with him there.
The rest is just applying money, imagination, and making a few connections.
This takes about three minutes to explain. The rest of the time you just carefully describe the results.
