Georgetown, TX – This Friday, October 31, 2025, marks the anniversary of a tragic unsolved case, and the Williamson County Sheriff’s Office continues to actively investigate the death of Debra Louise Jackson.
On October 31, 1979, a civilian discovered the body of an unidentified woman in a concrete drainage ditch along the southbound side of Interstate 35 near FM 972 in Georgetown. The victim was found nude except for a pair of orange socks.
At the time, she was described as a white female in her late 20s, approximately 5 feet 4 inches tall, weighing about 125 pounds, with reddish-brown hair and hazel-blue eyes. She wore a silver elongated oval ring with a white stone on her right middle finger.
