Three sex workers were found strangled to death in Ventura County in 1977. Decades later, in 2023, the cold case unit reexamined the case and identified Warren Alexander, a former truck driver, as the primary suspect. But he's not the only truck driver to kill. Ana Garcia speaks with Frank Figliuzzi, the FBI's former assistant director, about what drives some long-haul truckers to become serial killers.

Fifty-three-year-old Vicki Friedli, her 55-year-old boyfriend Jon Hayward, and Vicki’s 18-year-old daughter, Becky Friedli were found dead in their burning home. Vicki and Jon had been gunned down. Becky, who investigators suspect was the intentional target, was discovered deceased and on fire in a wheelbarrow. Her body was so badly burned that her cause of death could not be determined. Over a decade later, Becky's family finally got justice when her ex, Robert Pape, and his best friend, Cristin Smith, were convicted of murder.
