We have a story of what seemed like an ordinary american family. Turns out they were leading an extraordinary double-life. After tragedy struck, the dad recruited his kids into the family business, robbing banks. Abc's matt gutman spoke to all of them. Reporter: This morning, for the first time anywhere, exclusive details about how the family, scott and his kids, 21-year-old hayden and 19-year-old abby, went from the suburbs in oregon to a cell block in texas, pleading guilty last week to a brazen bank heist near houston. It begins and ends with dad. Nice to meet you. Reporter: Once the head of a churchgoing family, after his wife, beth, died after a battle with breast cancer. How did you deal with it personally? His kids grew close as he strayed. There were arrests, disorderly conduct and a new expensive vice, cocaine. The money got tight. Scott launched a new career. You decided in order to make ends meet, you had to do things a little bit outside the box. Right. Reporter: Robbing banks. And in late 2012, he would coax those kids, those siblings, as close as soul mates, into the family business. Your father says, I have a plan to rob a bank. Shouldn't your first reaction be, are you crazy? Looking back on it, I can't believe that wasn't my first reaction. In some way, I was led on, like, this is how I protect them. And these are the only people i have. Reporter: Together, they took down two banks, netting $100,000. They got busted spending the last year at a texas jail. But just last week, we learned that scott had written his kids a letter, asking him to accept jail time as a bargaining chip so his sentence will be reduced. We went back to confront scott, face-to-face. It seems you're trying to manipulate them behind bars. What do you want me to say to that? Reporter: For his role in the robberi robberies, hayden accepted and got ten years in a penitentiary. Abby was sentenced to five years. Making an unprecedented gesture, we were allowed to bring them together one last time, before they serve their sentences. I love you. I love you, too. Reporter: Their love for each other, the only thing their father couldn't destroy. For "good morning america," matt gutman, abc news, new york. Wow. A lot more on that on "20/20"
