Murders in Groton - BONUS EPISODE: Deadly Sister - The Diary Murder

In 1996, sixteen-year-old Stephanie Santerre disappeared from a home in Groton, Massachusetts.

At first, it appeared she had simply left after an argument. But as investigators began questioning the people closest to her, a far more disturbing story emerged—one involving a private diary, dangerous jealousy, and a betrayal from inside Stephanie’s own family.

Nearly thirty years later, a landmark court decision would bring the case back into the spotlight and force Stephanie’s loved ones to confront the past once again.

BONUS EPISODE: In Part Three of Murders in Groton, we uncover the truth behind Stephanie’s disappearance and the secret that tore an already fractured family apart.

This is Deadly Sister: The Diary Murder.

This episode discusses murder, sexual conduct involving a minor, and domestic violence. Listener discretion is advised.
