In April 1980, fourteen-year-old Laureen Rahn vanished from her home in Manchester, New Hampshire.

There were no signs of a struggle. No witnesses. No clear explanation for how a teenager could disappear from a third-floor apartment in the middle of the night.

In the hours that followed, investigators were left with only a handful of details - a friend asleep inside, an open back door, and a timeline that stopped at the moment Laureen moved from her bed to the couch.

Months later, a series of phone calls would surface, pulling the case thousands of miles away from New Hampshire…and raising questions that have never been answered.

In Episode 1 of SEQUESTERED Season 4, Sara Reid reconstructs the final known hours of Laureen's disappearance; and the quiet, unresolved mystery at the center of a case that remains open more than four decades later.
