Sharon Russ McCool, 35, was found dead on July 24, 1998, near the intersection of Great Oaks Drive and Conchos Valley Drive in Round Rock, Williamson County, Texas. A passerby discovered her body and notified authorities. The autopsy determined death from blunt force trauma to the head, and the death was classified as a homicide.

The case went cold for a time because investigators initially lacked strong leads or a suspect. The Williamson County Sheriff’s Office Cold Case Unit has continued to work the investigation over the years, pursuing new forensic avenues. DNA and other samples taken from her body, including evidence under her fingernails and from personal belongings, have produced some potentially useful results.

Detectives have employed newer forensic techniques, including DNA analysis and genealogical research, and remain hopeful that collaboration with outside labs will help narrow a suspect profile. The case remains active as authorities pursue every possible lead to bring closure to McCool’s family. If anyone knew Sharon, saw her in Round Rock around July 24, 1998, or has information specific to this homicide, please come forward.
