Sonya Wallace


WILCO – The Williamson County Sheriff's Office, Cold Case Unit, is requesting assistance from the public to help identify the people or person responsible for the murder of Sonya Wallace.

On Feb. 19, 1999, 15-year-old Wallace left her home in Rockdale to walk to the post office four blocks away to mail a letter. She never returned home.

Three weeks later, on March 14, her body was found in a creek bed in Eastern Williamson County.

At the time of her disappearance, Wallace was attending Rockdale High School and spent her time away from school in Rockdale, Taylor, Elgin and North Austin. Wallace had many friends that she associated with, and detectives believe her then high school friends would have vital information about

her disappearance and the circumstances involving her death.

Sheriff Robert Chody formed a specialized Cold Case Unit in July 2017 to investigate 11 unsolved murder cases that date back to 1979.

"With the Cold Case Unit, Williamson County is taking meaningful steps to bring to justice those persons who have eluded law enforcement for decades," Chody said. "I urge anyone with information to come forward regarding the death of high school student Sonya Wallace."

Anyone with information about the disappearance and death of Sonya Wallace, contact the Williamson County Sheriff's Office Cold Case Unit at 512-943-5204 or via email at

If you have a tip that could help solve this “cold case” please contact Crime Stoppers. If your tip leads to an arrest you could qualify for a reward of up to $2,000.

Williamson County Crime Stoppers provides three methods of receiving anonymous information from callers: a toll-free “800” phone number (1-800-253-7867), a web site ( and a mobile app (P3Tips) where a web tip can be submitted. Citizens, when contacting Crime Stoppers, are asked questions relating to the crime they are reporting and how they are aware of the crime. They are never asked any questions that may reveal their identity.

A tip number is assigned to the caller, which is a means of identification when calling back to see if the information has been valuable in solving the crime, and as an identifier when picking up rewards.

Williamson County Crime Stoppers respects the anonymous person’s right to privacy and does not collect any personal information concerning them or their use of the website, the 800 number or our mobile app. Crime Stoppers does not use or disclose personal information to anyone, and cannot sell personal information.

Anonymity is safeguarded legislatively as well as administratively by procedures implemented to ensure its protection. Guarantying a tipster’s anonymity is Crime Stoppers’ first priority. According to Crime Stoppers, anonymity is not a promise, “it is the law.”
