Summary

Written by a model from the transcript; not yet reviewed.

This episode explores the brutal 1985 murder of 17-year-old Missy Avila in the Angeles National Forest and the extraordinary deception that followed. The guest and host detail how Missy was lured to Big Tujunga Canyon by two lifelong friends, Karen Severson and Laura Doyle, and murdered over petty high school jealousy and rumors. Afterward, Karen moved in with Missy's grieving mother, Irene, comforting her and helping search for clues while concealing her guilt for nearly three years. The discussion examines the psychological toll of teenage cruelty, the eventual arrests following a witness coming forward, and Missy's family's enduring fight to change California law regarding criminals profiting from their crimes.

The episode highlights the shocking betrayal of a surrogate daughter hiding in plain sight and the resilience of a family determined to keep Missy's memory alive through documentaries and recorded confessions. Listeners get an in-depth look at a harrowing true crime case where the perpetrator lived with the victim's mother, demonstrating how teenage drama escalated to unthinkable violence and how advocacy eventually birthed Missy's Law.
