TAHLEQUAH, Okla. (AP) — Two families fighting for custody of a 3-year-old Cherokee girl have filed a mediation agreement in an effort to determine the best way to raise the child. Dusten Brown is trying to prevent his daughter Veronica's adoption by a South Carolina couple. The U.S. Supreme Court says Brown cannot use the Indian Child Welfare Act to press his claims, but a Cherokee Nation court has granted him and his family custody of the girl. Cherokee County Court Clerk Shelly Kissinger says paperwork was filed in state court noting that a mediation agreement has been filed. Matt and Melanie Capobianco appeared with Brown and his family in state and tribal courts on Friday. Both families left the tribal courthouse without commenting. The girl was not seen at either hearing.
