Shane Stewart was 16 when he and his girlfriend Sally McNelly vanished after going to watch a July 4, 1988 fireworks display at Lake Nasworthy in San Angelo, Texas. The pair were last seen that night and drew an extensive search. Their remains were found months later in the Twin Buttes area, about 17 miles from where they had been last seen; Shane and Sally had both died from shotgun wounds and their killings remain unsolved.

The case attracted intense local attention amid the era’s Satanic Panic. Reports said the couple had attended gatherings where occult rituals were allegedly performed, and in March 1988 they turned a firearm over to police that they said had been given by a cult member and used in a crime. Investigators have continued working the case; in 2016 the FBI provided behavioral analysis and other support to the Tom Green County Sheriff’s Office, but no arrests have been announced.

If anyone knew Shane, Sally, their activities that summer, or has information about the Twin Buttes area that could help, please come forward.
