In the quiet town of Price, Utah, where tranquility is the norm, the summer of 1970 bore witness to a gruesome murder that forever altered the life of 4-year-old Heidi Jones. The haunting image of her mother, Loretta, lying lifeless as viewed from the keyhole of her bedroom door is an indelible memory that haunted Heidi throughout her life. It ignited an unwavering determination to ensure her mother's murder would not remain unsolved.

But it would be 46 long years before Heidi's relentless pursuit of justice would find an ally in David Brewer, a high school acquaintance turned Detective Sgt. Together, they would stir up the embers of this forgotten homicide.

Who could have taken the life of a 23-year-old single mother, and what could have been the motive? A suspect had been apprehended and then released, going on to live a life untouched by justice, while Heidi grappled with the frustration of a system that refused to push forward.

Undeterred, Heidi continued her quest for the truth, unearthing a photograph that revealed a message from her dying mother. Yet, law enforcement still hesitated to make an arrest. Faced with no other recourse, Heidi embarked on a final, desperate gambit: the exhumation of her mother's body.

Through the Keyhole is a harrowing true story that delves into a brutal rape and murder, a child's haunting memory, and a lifelong odyssey to bring her mother's killer to justice.
