At 15, Norma Countryman chewed through her bindings to escape a suspected serial killer.

The case of a man in Washington, Warren Forrest — a convicted double murderer believed to be connected to a series of homicides from the early 1970s — is the focus of a new true crime podcast by Lemonada Media titled “Stolen Voices of Dole Valley.”

The series, hosted by Carolyn Ossorio, takes an in-depth look at the case through the eyes of loved ones and investigators. In it, Countryman shares her story in hopes that her account will spark new leads for families still seeking justice.

In early 2024, Clark County Sheriff John Horch re-established a cold case team focused on Forrest’s crimes. With the help of modern DNA technology, investigators are analyzing trace evidence, including hair and nail samples from Forrest’s van.

“The sheriff’s office is pressing him to confess to these unsolved cases,” Ossorio said. “It’s possible there are victims in other states because of his military service. But he insists he doesn’t remember. What we know is that he avoids publicity. He doesn’t like to talk about his crimes. He’s not the kind of serial killer who brags. He just wants silence. But the pressure is on.”

Ossorio said loved ones won’t stop pushing for answers. The Clark County Sheriff’s Office told Fox News Digital in a statement that it remains committed to bringing justice to the victims and their families.

“Listening to these stories will make you sad, but they will also inspire you,” said Ossorio. “These are people who are fighting for justice, for answers. And through trauma, they’ve leaned on each other. It’s a story of not giving up.”
