"[Rodney] had a child out there and he wanted to know where this child was. And he wanted his child," Katie Wegg told 20/20. "These guys didn't know they had children."
In 2007, Finley served an eight-month sentence for forging checks to Rodney Wegg's account.
Finley was arrested again in June 2010 in New Orleans for allegedly skipping out on a pricey dinner tab. She was extradited to Alabama, where she pleaded guilty to a felony theft charge related to a furniture purchase, was sentenced to jail time and was ordered to pay nearly $5,300 in restitution.
Many of her alleged victims said she deserved to stay in prison for the rest of her life. Chris Cuomo brought together nine former husbands and fiances for an exclusive group interview in which they shared their stories of emptied bank accounts and broken hearts.
"I mean, I'm angry. I'm sad. I'm lonely ... because of what Bobbi did," Jeffrey Dietiker, one of Finley's ex-husbands, told Cuomo. "And now I'm paying for it, with every relationship I get in. ... Trust was everything I had, and now I don't."
Finley told Cuomo that while she may be "the most hated woman in America," she believes the title is undeserved. While she admitted that she had a history of writing bad checks, she insisted she is not a con woman, bigamist or bad person.
"I was looking for love. I was looking for understanding, I was looking for someone to say, You know, it is going to be OK," Finley explained. "In many of the cases, you look and you started out and you get married and you're thinking, 'Oh, I'm going to live happily ever after.' And then you realize as soon it's done ... it was a mistake," she said.
But the men say her explanation is just another con.
"She's a domestic terrorist," said ex-husband Ben Giles. "As a military member, we were sworn to protect this country against all enemies, foreign and domestic. She is targeting military members. She's destroying their lives."
