On the morning of December 20, 2025, a shooting at a residence in the 9000 block of Markville Drive in the Lake Highlands area of Dallas left 30-year-old Nadia Swanson with a fatal gunshot wound. Dallas Police units were dispatched around 10:15 a.m.; Swanson was transported to Texas Health Presbyterian Hospital by Dallas Fire-Rescue but was pronounced dead at 11:11 a.m. The shooter fled before officers arrived.

Detectives identified 32-year-old Gerald Frank Martin as the suspect and determined he and Swanson were acquainted. Family members said the shooting may have followed an argument, though investigators had not announced a motive. Police tracked Martin to Mesquite and conducted a coordinated felony traffic stop near the 18500 block of the North LBJ Freeway around 11:45 a.m. Martin exited his vehicle armed and an armed confrontation with officers ensued; officers shot and fatally wounded Martin at the scene. No officers or bystanders were injured. Because the suspect died at the scene, no arrests were made in connection with Swanson’s homicide; Dallas police continued to investigate while Mesquite police and the Dallas County District Attorney’s Office opened inquiries into the officer-involved shooting.

Swanson was the mother of five children; her mother, Shashawn Swanson, said the family has unanswered questions. If anyone knew Nadia, her movements that morning, or saw activity on Markville Drive, please share what can help the investigation.
