By Michael Pearson , CNN updated 10:07 PM EDT, Fri May 10, 2013 (CNN) -- DNA tests confirm that Ariel Castro is the father of a 6-year-old girl born to one of the three women he is accused of keeping in captivity for more than a decade, the Ohio attorney general's office said Friday. Castro's DNA did not match that from any other open Ohio cases, according to Dan Tierney, a spokesman for the attorney general's office. National results are pending through the FBI, he said. Amanda Berry's 6-year-old daughter was among those rescued Monday when Berry escaped from the home where police say she had been held since Castro allegedly lured her into his car on April 21, 2003. Also freed: Michelle Knight, who disappeared in 2002, and Georgina "Gina" DeJesus, who vanished in 2004.
