My 7 yo son was living with his mother in Cali,(we have 50/50 custody) until recently. I spoke w my son one a week as I live in Idaho. Then about a month and a half ago he stopped calling, after numerous attempts at contact I finally sent police over for welfare check. They told me my son was in foster care according to his mother. I called DCSF and found out his mother was arrested for meth possession, and trafficking. I asked why they didn't contact me, they replied that they sent mail to my last addresses. When they asked the mother of my whereabouts she told them she didn't know and gave them a number I used 6 years ago. What rights do I have to get my son released to me? I have home job no criminal ...
