Surfin,
There is an ongoing discussion about this issue here on FR. If you would like to join that discussion, I would be happy to find that thread for you.
In the meantime, please, we would like to focus on Baby Billy and efforts to bring him back.
One of the endearing things about FR is that when one of us has a concern, the community here rallies.
Please ... have her contact her local Domestic Violence Center. I have worked in these Centers off and on for nearly 20 years.
They have contacts all across the Country ... in uniform and out ... and help in many ways ... not only emotional.
Without being too specific ... they can be very useful in successfully locating and retrieving a "lost" child ... and have done so on many occasions ... with little or no fanfare ... for they work behind the scenes, so to speak ...
Please ... add these folks to the many trying to help ...
