Transcript for Brother and Sister Bank Robbers Connect on Camera
But we start with the bank robbers who kept it "All in the family." A father turning his kids onto a life of crime, each playing their part. Now they're locked up and cameras right here catch a brother and sister's final embrace for what may be a decade. ABC's mat Gutman bringing us this interview. Reporter: Apparently the family that stays together, robbed together. It begins where it ends with dad Scott cat. Scott cat fell in love and married his high school sweetheart, Beth. Beth cat would die at the age of 32, leaving behind 4-year-old Hayden and 2-year-old abbey. Yet, the children thrived, leading a seemingly Normal childhood. We were very close. My sister is the only consistent thing I've had my whole life. My brother is my best friend. He was basically the only one that was there for me. Reporter: What Scott's kids worried about most, their dad's drinking. He partied away their savings. That's when he said would you be willing to do something to get some money. Scott talked his sister into joining their gang. I was led on like this is how I protect them. This is the only people I have. Where there are robbers, there are cops. And the cops were already onto them. When Scott was arrested, the detective that made contact with him told him you're under arrest for bank robbery. Scott's initial response to that was which one. Reporter: Investigators were about to learn that Scott cat's secret life of crime dated back to the Clinton administration. He didn't even ask for a lawyer before he started spilling the beans. The family had been held in separate cell blocks and hadn't even each other in over a year. They had committed the crime. Now came the punishment. For abbey, all she has left is her brother, Hayden. Making an unprecedented jess to tour, the sheriff allowed us to bring them together for one last time before they started their sentences. The rules were strict, no touching. The sig lgs couldn't seem to help, reaching out, breaking one last rule. Abbey, I'm sorry, okay? I don't blame you for anything. Just know that I love you forever. If you guys want to give each other a hug, the sheriff said it's okay. Reporter: Listen closely, our mics picking up abbey's heart pounding. The siblings' love for one another, the one thing their fool hearted father couldn't destroy. Incredible story. Look forward to seeing that full report. You can catch it tonight on "20/20" Saturday at 10:00 right here on ABC. What a spectacular moment that you could hear her heart pounding through her chest caught by those microphones. Again, you can see much more of it tonight.
