Anna Christian Waters was 5 when she vanished from the family’s rural home near Half Moon Bay, California, on January 16, 1973. She was last seen in the backyard around 2:00 p.m., after coming home from kindergarten. Searchers checked nearby Purisima Creek, which was flooded then; a fall into the creek was first suspected but later ruled out.

Suspicion in the case has centered on several unidentified outsiders and people known to the family. A family friend reported seeing two unidentified men in a white panel truck near the house just before Anna disappeared. About a month earlier, Anna’s younger half-brother remembered a man and a woman who tried to lure her into their vehicle; that couple was never identified. Attention also focused on Anna’s biological father, George Waters, and his associate George Brody, who reportedly behaved oddly and whose relationship contributed to family tensions; Brody reportedly believed Anna was a reincarnation of someone he had known. No concrete evidence tying any person to Anna’s disappearance has been reported, and her fate remains unknown.

Does anyone have memories or information about the area, the white panel truck, or the people seen near the Waters home in early 1973?
