Christopher Rider, a 31-year-old man from Dallas, Texas, was shot and killed on October 18, 2017. Dallas police who responded to a reported shooting found Rider lying face down with no pulse; paramedics pronounced him dead. A handgun with a chambered round was recovered under Rider’s shirt at the scene.

Surveillance footage showed a white pickup truck arrive and a man identified as Anthony Quinn Rider point a gun at Christopher Rider and fire multiple shots before leaving in the truck. Witnesses said another person, Harvey Hughes, fired at Rider as the truck drove away. A search of Anthony Quinn Rider’s home produced the white pickup in his garage with two bullet defects and four shell casings in the truck bed. In a post-arrest interview, Anthony Quinn Rider said he had been in the area selling marijuana.

A jury convicted Anthony Quinn Rider of murder and sentenced him to twenty-seven and a half years in prison; the trial court’s judgment was later affirmed on appeal. Does anyone have information about Christopher Rider’s activities that night or images from the area that could add detail to the timeline?
