ANTIOCH, California (CNN) -- In many respects, Jaycee Dugard and her two daughters lived an unremarkable public life -- one that belied the horrifying circumstances that have since made front-page news. Dugard's daughters attend a birthday party two weeks ago. CNN has blurred their faces to protect their privacy. Dugard, kidnapped 18 years ago in South Lake Tahoe, California, helped manage the small printing company her alleged captor, Phillip Garrido, ran from his home in Antioch, east of San Francisco. Her two daughters, fathered by 58-year-old Garrido, attended birthday parties and, like many girls their age, shared a love for the TV show "Hannah Montana."
