  • Gwendolyn Graham & Cathy Wood: The Lethal Lovers
    Dec 9 2025

    Retired FBI agent and criminal profiler Candice DeLong unravels the horrifying case of Gwendolyn Graham and Cathy Wood, also known as the “Lethal Lovers.” Inside the walls of a Michigan nursing home, their romance became intertwined with violence, as the pair used murder as a way to deepen their emotional and sexual bond. Over several months, vulnerable patients became targets in a shared, intimate thrill – a lethal fusion of affection, manipulation, and desire. Candice explores how their toxic dependency escalated into a series of killings, and how a relationship built on control, obsession, and the pursuit of shared gratification spiraled into one of the most disturbing partnerships in criminal history.
