On April 16, 1992, 21-year-old Hispanic woman Maria del Carmen Estrada was walking to work in Houston when she accepted a ride from Anthony Allen Shore. Shore, described as a former telephone repairman and wrecker driver, later confessed that he made unwanted sexual advances, that Estrada resisted, and that he overpowered, sexually assaulted and strangled her. He used a nylon cord tightened with a wooden stick in a tourniquet-like fashion. Maria del Carmen Estrada’s body was found later that day in the drive-thru lane of a Dairy Queen restaurant.

The sequence raises questions about where the encounter began and how Estrada came to be in the Dairy Queen drive-thru so quickly after leaving for work. Anyone who knew Maria del Carmen Estrada, saw her that morning, or remembers the area near that Dairy Queen on April 16, 1992, is asked to come forward with information.
