He is not allowed to have any contact with a minor in any pretenses, each time this happens it needs to be reported to local athorities.

sounds like your wife is a bit lonely and insane why involve yourself with a known criminal in todays world shes just asking for trouble. That is very bad parenting if you are co habiting with prison inmates while you have children at home. your life is supose to be rasing your kids when you become a parent, not oh my god!  i need i need what i want any more. If she is letting your son talk to prison inmates you should take it to a court and let the judge put your son on stand and tell them that she is allowing your son to communicate with a level 3 sex offender. but first talk to your son and tell him that your not trying to hert his mother in anyway but ensure that he dosnt become hert from his mothers mistakes. Is this  sex offender gay? why is a grown man emailing a child what dose he want from your kid? this whole thing sounds sick to me if my son was texting some man from prison i'd kick his ass tell him what the hell i think curse out his mom and tell her where she can go. its your kid dont let this situation over power you fix it or not. sounds like the women is mad cause you dont want her anymore and shes making it hard for everyone else
