Neighbors knew them as a mother and her polite teenage daughter before police swarmed their home in a small, quiet city in South Carolina. Gloria Williams was arrested on kidnapping charges. Then came the real shocker: Police identified the victim as the 18-year-old woman Williams had raised as her daughter. Investigators said DNA analysis proved she had been stolen as an infant from a hospital in Jacksonville, Florida. Now the woman who grew up as Alexis Manigo has learned she was born Kamiyah Mobley. Jacksonville Sheriff Mike Williams described her Friday as being in good health but emotionally overwhelmed. Tesha Stephens, a cousin of Willams', said the young woman had much to think about. "She's probably going to have to take this day-by-day," Stephens told reporters outside Williams' home. Meanwhile, the young woman's birth family cried "tears of joy" after a detective told them their baby had been found. Within hours Friday, they were able to reconnect over FaceTime. "She looks just like her daddy," her paternal grandmother, Velma Aiken of Jacksonville, told The Associated Press after they were able to see each other for the first time. "She act like she been talking to us all the time. She told us she'd be here soon to see us." Mobley was only eight hours old when she was taken from her young mother by a woman posing as a nurse at University Medical Center. A massive search ensued, with helicopters circling the hospital and the city on high alert. Thousands of tips came in over the years, but she had disappeared. Some months ago, the young woman "had an inclination" that she may have been kidnapped, the sheriff said. Authorities didn't say why she suspected this. The case broke thanks to a tip received by the National Center for Missing and Exploited Children, said Robert Lowery, a center vice president. He would not say from whom the tip came. But the center soon reached out to the cold case detectives at the sheriff's office, and Mobley provided a swab of her cheek for DNA analysis that proved the match, the sheriff said.
