Connie Gail Minchaca was 17 when she was last seen in Napa, California, on June 9, 1978. A family friend dropped her off in the late afternoon at a western clothing store where she was to meet a friend; she had planned to attend a party that evening but never arrived. Connie had run away several times in the months before her disappearance, and family tension over a relationship with a 25-year-old man who lived in the area was reported. Unlike previous episodes, she left all of her personal belongings behind, so the family believed she had not intended to leave for good.

In the weeks after she vanished the family received a series of anonymous phone calls from both male and female voices claiming Connie had been kidnapped or murdered; the calls were never traced and the callers remain unidentified. Authorities classify the case as endangered missing and suspect foul play, though no definitive conclusion has been reached. Some have suggested a possible link to the East Area Rapist/Golden State Killer, but no conclusive evidence ties Connie to those crimes. No trace of Connie has ever been found and the Napa Police Department continues to list the case as open.

If anyone knew Connie, the friends she planned to meet that day, or has information about the anonymous calls, please share what is known.
