On a new path, far from home, Shasta Groene clears her mind. The 18-year-old walks the paved streets of southern Idaho, searching for inner peace. This is her new home and her new life, far from the troubled young girl who experienced tragedy a decade ago.

The community prayed for Shasta and Dylan’s safe return, holding vigils, and openly weeping with despair at the idea of two sweet, local kids stolen from their quiet community. More than a month passed, and many believed hope was lost. They were wrong.

Shasta says she became a celebrity victim, defined by tragedy and plagued by guilt.
