Debra Louise Jackson, 23, was found dead on October 31, 1979, in a concrete drainage culvert near Interstate 35 just north of Georgetown, Williamson County, Texas. She was discovered nude except for a pair of orange socks and an abalone-shell ring, and had been strangled. Her body showed several scars, including marks consistent with healed impetigo, details that later aided identification.

In the 1980s Henry Lee Lucas confessed to the killing, saying he picked her up as a hitchhiker, but his confession was later discredited and his involvement remained doubtful. Jackson stayed unidentified for nearly 40 years until DNA work in 2019 confirmed her identity after a sister recognized long toes and distinctive earlobes. Jackson had not been reported missing because her family believed she had chosen not to return after leaving in 1977; she had worked in Amarillo and Azle in the late 1970s.

Her murder remains unsolved; the Williamson County Sheriff’s Office and Crime Stoppers ask anyone who knew Jackson or who saw her in Abilene, Amarillo, or Azle between 1977 and 1979 to come forward with information.
