Anna disappeared while playing outside in her own front yard on January 16, 1973. Both Anna's family and Doug French have felt that Anna's birth father and his friend are strongly involved with Anna's disappearance.[1][8] "Brody" is described as manipulative over Anna's father, having allegedly caused the divorce between him and Benedict. "Brody" was interested in Anna and believed her to be the reincarnation of a woman he had once lived with. He tried to make Benedict change her daughter's name to "Eifee". The word had no meaning. "Brody" simply wanted to do this so, numerologically, Anna's name would add up to his own name.[1] A young man and an old man were seen in the vicinity the day Anna disappeared. A spokesman from the National Center for Missing and Exploited Children has said that Anna may well still be alive. Officially the case is considered a "probable non-family abduction". "Brody" died of cancer in December 1981 and a short time later Waters, who had signed Brody's death certificate, was also found dead.
