How do I get my adopted daughter back after she moved in with her mother? 2 Answers as of January 07, 2012

I need to get my granddaughter from Portland, Oregon. i adopted her and she has been living with her mom and step dad. I adopted her in 2002 and it was open adoption and she saw her mom as long as she was in recovery and it was supervised. Mom got 6 years clean and wanted to have daughter live with her to see how it would go. The judge said to give it a try as 14 year old asked for it, so she went to Oregon and the mom relapsed on drugs and left the house. The son in law won't let me see her or talk to her. He only has a temp guard paper I notarized from bookstore for school. How can I get her with the police escort? They say I needed a court order for officer assistance, so I went up there went to court and now the judge denied it because of my adoption paper don't say I have full custody. The soc serv from Oregon was floored because the papers don't single it out, but the child becomes yours just like a natural child, so how can I get my daughter back with police help?
