Sally Ann McNelly, an 18-year-old white woman from San Angelo, Texas, was murdered on July 4, 1988. She and her 17-year-old boyfriend, Shane Paul Stewart, went to Lake Nasworthy for the fireworks display and did not return. Their car was found abandoned; in November 1988 both were found dead in a pasture near Twin Buttes Reservoir, about 20 miles from where they were last seen. Both victims died of gunshot wounds to the head.

The case drew national attention amid rumors that the two were involved in a Satanic cult. In March 1988 Sally and Shane turned over a gun to police they said had been given by a cult member; the gun was later identified as stolen. In 2017 the Tom Green County Sheriff’s Office named John Cyrus Gilbreath a person of interest after locating writings, audio tapes, and biological material in his home that might be connected to the murders. No arrests have been made.

State investigators remain involved and Texas Crime Stoppers is offering a cash reward for information leading to an arrest. Does anyone have verifiable information about Sally, Shane, their last known movements, or the items recovered in the Gilbreath search?
