Sally Ann McNelly (March 26, 1970 – July 4, 1988) and Shane Paul Stewart (August 5, 1971 – July 4, 1988) were two teenagers who were murdered near Lake Nasworthy in San Angelo, Texas after spending the evening watching a fireworks display on the Fourth of July in 1988. Their murders, which remain unsolved, were attributed to rumors of a Satanic cult in which they both were involved. The case received national attention among the Satanic panic phenomenon of the 1980s, and was profiled in national media as well as on Unsolved Mysteries.
