Nope when it comes to children/minors there is no such thing as a "48 waiting period". That is only done in movies. No charge for being a boyfriend to a minor either. (Although if it was my girl, they would have hell to pay!) Unless you have proof that some type of "sexual contact" has occured. Well atleast here in Texas anyways. Anyways that is not important now. Any news?????!!!!!!!!!Wow... I don't have anything to add other than to express my hope that things turn out well. Is the 'boyfriend' over 18? You might be able to get some sort of different charge based solely on that. I think that a "missing person" has to be missing for 48 hours... maybe some kind of statutory claim would get things moving.
And, FYI, the proper term is "Hanged"... so when we're all yelling loudly for it, we'll all be on the same page.
