Linda Sue Peterson was 29 and five and a half months pregnant when she was last seen on September 16, 1978. A nurse at the University of Utah Hospital, she reportedly stopped by her husband William Phil Peterson’s workplace—a pharmacy near 700 East and 2100 South in Salt Lake City—and left in a station wagon with two women, one husband said was named Susan or Suzanne. Friends and family told police Linda had no plans to travel to Kentucky, and there is no evidence she ever left Utah.

Her husband did not report her missing until September 30, 1978; he later stopped cooperating with investigators, moved out of state, and has since died. Linda’s mother had been sending furniture for the baby and normally spoke with her weekly, so the sudden silence was out of character. The two women allegedly seen with Linda have never been identified.

Investigators have faced obstacles including Linda’s adoption, which delayed obtaining reference DNA. Two biological siblings were eventually identified and their DNA entered into national databases. At disappearance she wore an orange maternity top and blue jeans, wore eyeglasses, had pierced ears, and had scar tissue on the inside of her mouth.

Does anyone have information about the two women seen with Linda that day or remember seeing a station wagon near 700 East and 2100 South on September 16, 1978?
