Ann Bernice Duncan, 31, was last seen October 3, 1969, in San Francisco when she attended a scheduled social services appointment about foster placement for her six-week-old son. She never returned for follow-up appointments and contact with her stopped; the baby was later declared abandoned and placed for adoption. Ann had other children in foster care whom she had visited regularly until those visits and occasional calls to her mother ceased abruptly in October 1969.

Family say she loved her children and feared for her safety; they suspect foul play. The San Francisco Police Department keeps the case open and seeks information.

Did anyone in San Francisco in 1969 know Ann or recall seeing her after October 3?
