A MISSING CHILD
Editor -- In Thursday morning's paper you mention several disappearances of children in the Bay Area, saying that Angela Bugay was the ``first in a series'' . . . My daughter, Anna Christian Waters, disappeared from our home in Half Moon Bay in 1973 at the age of 5; the case has never been closed in San Mateo County, and while I know it has been a lifetime since her disappearance, I feel somehow compelled to let people know she was never accounted for and that her disappearance was never resolved.
I wrote Marc Klaas recently and asked him if he thought I should simply put this behind me (the National Center for Missing and Exploited Children still circulates an age-advanced picture of Anna). He said that he didn't believe, had they not found Polly Klaas' body, he would ever be able to give up looking for her until the case was resolved in some way.
