In the fall of 1987, Shane Stewart and Sally McNelly met through mutual friends and began dating. Shane was tall and confident. Sally loved to be the center of attention and moved easily between groups of friends.  Later that year, the two began spending more time with a group of teenagers who met up to practice occult rituals. Some friends say the group's activities were just games, but by the summer of 1988, something had changed. Sally told one friend that she and Shane were leaving San Angelo to get away from the group. That was just before the two of them disappeared.
