Finally, after 3 weeks, my nephew is on the national missing kids site.
The information is here: http://tinyurl.com/36prax
I would add that he is likely already in Jasper, Alabama — hidden illegally by his birth mother. If not, he is being hidden on a tractor-trailer rig by his birth mother and her current husband, who is a truck driver. If that’s the case, he could be anywhere that the truck goes. So, concentrating on truck-stops would be helpful.
Please pass along where you deem appropriate.
