Among the most frustrating details in the Springfield Three case are a series of phone calls and one erased answering machine message. Friends reported receiving strange calls while inside the house, and an important recorded message was accidentally deleted before investigators could preserve it. Whether any of those calls were connected to the disappearances has never been confirmed.

In this episode of Unsolved and Missing, we examine what is actually known about the mysterious phone calls, what became internet legend, and why investigators have never been able to determine their significance.

Sometimes a clue disappears before anyone realizes it's a clue.
