The adoptive parents of a 3-year-old girl caught in a cross-country custody battle will hold a press conference in Oklahoma Wednesday morning as part of their quest to bring Veronica back to South Carolina.

Matt and Melanie Capobianco of James Island traveled to Oklahoma Tuesday and are staying with supporters in Tulsa.

The couple plan to speak at 11 a.m. at the Hyatt Regency Hotel in Tulsa, according to family spokeswoman Jessica Munday. She is with them, as well as Troy Dunn, an adoption reunion facilitator, she said.

They plan to discuss their efforts to bring Veronica back to South Carolina and ongoing legal developments in the case.

They are trying learn the whereabouts of Veronica, who has been in the custody of her birth father, Dusten Brown, for the past 19 months. Brown, of Nowata, Okla., and Veronica are members of the Cherokee Tribe.

The U.S. Supreme Court ruled in June that Brown wrongly got custody of the girl under the Indian Child Welfare Act.

After the case was sent back to South Carolina courts, the Capobiancos’ adoption was finalized but they have not yet been reunited with her.

The girl, who turns 4 next month, lived with the couple for the first 27 months of her life.
