Her awareness even before the amber alert went out may have saved that girl's life and abc's david wright has that story. Reporter: Something just didn't seem right. That's what 22-year-old roxana ramirez says about a man she spotted last friday at this bay area target. He was acting weird as if like he was up to something. Reporter: Aramirez's job is to watch out for shoplifters. He didn't steal anything but kept an eye on it anyway. Ramirez wrote down his license plate. Hours later a friend told her about an amber alert for a 7-year-old girl abducted from her own driveway. Ramirez put two and two together. The car looked the same. It might be the same person. Reporter: Local police say that tip-off helped them identify their suspect, david allen douglas. Once we knew who he was, we were able to look for him at the antioch arena because we have information that's where he liked to frequent. Reporter: That's where they made the arrest. The 7-year-old found in his car alive. She came with me and then she turned back an said, mommy. Reporter: Douglas has confessed to the kidnapping but showed no remorse in a rare jailhouse interview, in fact, told the bay area news group how easy it was to abduct the girl. She was scared. I said, I'm scared too. Reporter: Doug glass is now being held on $4 million bond.
