Chou Ung, 28, was shot in the head and killed on November 30, 2008, at a Chevron station in the 11300 block of Westheimer in Houston. She had just left her family’s restaurant, Chef Huang’s, after a shift and stopped to fill her car when a young black male, described as about 18 to 21 years old wearing a dark hoodie and black pants, approached her. A verbal argument occurred and the suspect shot Ung before fleeing on foot.

Two witnesses were at the scene but the case remains unsolved. Investigators treated robbery as a possible motive and the Houston Police Department and Crime Stoppers offered an $11,000 reward for information leading to an arrest and conviction. Ung’s family, who emigrated from Cambodia and operate several Houston restaurants, say she was studying education at the University of Houston and wanted to become a teacher.

Anyone who knew Ung, saw activity near the Chevron on Westheimer that night, or has information that could help the investigation is asked to come forward.
