Sandra Kay Powell was 16 when she vanished from South Bend, Indiana, on March 11, 1987, days before her 17th birthday and while four months pregnant. That evening she and a friend went out—reports say possibly to a YMCA or a health spa—but they became separated and Sandra never returned. The night before she had a phone call with an unidentified person, but no further details about that call are available.

Sandra had testified in a 1986 murder trial after witnessing the killing of a friend and received threats afterward; investigators have examined whether her disappearance is connected to that testimony, though no definitive link has been established. She was emotionally upset before she disappeared because the father of her unborn child had told her he was marrying someone else. Originally treated as a runaway, the case was later reclassified as endangered missing when no personal items were taken.

Despite tips over the years, including a possible sighting on Soul Train, Sandra remains missing. If anyone knew Sandra, saw her in South Bend in March 1987, or has credible information about her whereabouts, please come forward.
