Gabrielle Monique Simmons, 27, was shot and killed while working as a cashier at a Dollar General in Oak Cliff, Dallas, on November 6, 2017.

A 15-year-old boy was arrested on November 9, 2017, after tips and surveillance footage led authorities to him; his name has not been released because of his age. He was charged with capital murder and taken into custody by the North Texas Fugitive Task Force. Investigators say a second male acted as a lookout and remains under investigation; the suspect was transferred to the Dallas Police Department’s Youth Division for processing.

Gabrielle was a mother of six. Her fiancé, Aris Joseph, has been caring for the children while the community has organized fundraisers and support. If anyone has information about the robbery or the second male involved, please share what you know with investigators.
