Some disappearances don’t fade.

They linger — because they are unresolved.

In small towns, especially, when a missing child becomes part of the landscape. A name whispered. A memory that refuses to settle.

This is the story of two teenage girls who vanished within a year of each other — in towns just miles apart — along the New York–Pennsylvania border.

One girl was never found.

The other was found murdered.

And decades later, their stories remain strangely, hauntingly connected. This is the stories of Mary Lou Bostwick & Sharon Coston.
