Who's Your Daddy? Paternity Battle Between Brothers

"Look, she had a bunch of girlfriends to the rodeo and they got drunk and she went banging on Raymon's door trying to have sex," Copeland said. "He says he did reluctantly…but I can't imagine it was reluctantly — and that's when the baby was conceived I guess."

As for the mother, Holly Marie Adams just wants the whole battle to be over.

"We've been to court over and over and they always ruled the same way," Adams said. "We are tired. We are done with this."

Family Feud

Richard, while admitting that he had a sexual relationship with Adams, believes that there is no way that he is the father and said that his brother just doesn't want the financial burden of a child.

"Raymon's the one that done everything," Richard told ABC News. "He's the one that brought this to court. It's just him not wanting to pay child support. It's a big mess if you ask me."

The two brothers are not the only ones in an awkward situation. Jean Boyd, the mother of the twins (and the child's grandmother — they're sure she is the grandmother) has felt caught in the middle. "When this first happened I felt like I had gained a granddaughter but lost my sons," Boyd said. "The boys have been feuding and I can't choose between my kids." While Boyd sees her granddaughter regularly, she said the paternity confusion is what has kept her sons from the child. "Until they know that the daddy is the daddy and the uncle is the uncle, Raymon will never acknowledge the child. And Richard doesn't think it was his either…neither of them will have anything to do with her," Boyd added.

Clones

It seems, however, that the Millers and the courts will never know the true father.

"With identical twins, even if you sequenced their whole genome you wouldn't find difference…they're clones," said Dr. Bob Gaensslen, a forensic scientist at Orchid Cellmark labs in Texas. "There are a few things in science that are cut and dried and this is one of them."

Dr. Bob Giles, a paternity testing expert, agrees. "There is simply no test that explains the difference between two identical twins," he said.
