Carlos,
I can empathize with your plight. My son was also abducted to Mexico by my ex husband almost 20 years ago - in my case I had a lot of luck on my side and was able to recover him within three weeks. Even after all these years the wound is still raw and every time I read of cases such as yours and David Goldman's my heart aches for your pain and your loss. Keep on fighting the good fight, your boy will be in your arms one day!
