  • Cynthia Burger 1993: Killer Asks Girlfriend To Help Him Escape Before A DNA Test
    14 Oct 2026

    In August 1993, Cynthia Burger, 44, was found dead in her home in Port Hueneme, California, after a fire that reached a single room. A sample kept from that first day waited years for a name. In 1999, a prisoner who expected to be released within months asked his fiancée to help him escape. What was he afraid of, and what did she do with the answer?

    Narrated with a synthetic voice.
