What Happened To The Springfield Three?

In 1992 the town of Springfield, Missouri was home to a triple disappearance that has baffled many. Suzie Streeter, Stacy McCall and Sherrill Levitt all disappeared without a trace in the early hours of June 7th and although there have been a number of theories and numerous suspects in their kidnappings the case is still open. So what happened to the trio that night? Kidnapping? Murder? Did they run away from life? Did they run away from Matt?

I know which one is most likely.
