Sgt. Hill thanks Roberto for all that he's done. "Frankie has been there for me. She's been my rock when I've needed her to help me out with a flashback or a nightmare. I can do things that for a year and a half I couldn't do," Sgt. Hill says.

Roberto is moved. "This is an overwhelming feeling, and to see you is breathtaking," he says. "And to see what Frankie had done in your life."

Now paroled, Roberto is expected to be released from prison this summer, but what he learned from Puppies Behind Bars will stay with him forever. "Being able to be involved in the puppy program has taught me to be a responsible person," he says. "It has taught me patience."
