In the pre-dawn hours of Thanksgiving morning, November 28, 2024, thirty-five-year-old Casey M. Plumb of Acworth was found dead in the roadway at Moon Station Road and Bayswater Drive in Kennesaw, Georgia. Plumb, born May 12, 1989, in Denver, Colorado, had sustained multiple gunshot wounds and was pronounced deceased at the scene.

Plumb worked as a plumber and was described by family and friends as generous, who enjoyed fishing, hunting, and gold panning. Investigators say detectives used witness statements and technology to identify a primary suspect. On November 30, 2024, 34-year-old Dain Mark Ryner of Powder Springs was arrested and booked into the Cobb County Adult Detention Center without bond. An arrest warrant alleges Ryner shot Plumb in the head and arm while Plumb was in a vehicle; Ryner faces charges including felony murder, aggravated assault, and possession of a firearm during the commission of a crime. Authorities have not released a motive or said whether the two knew one another, and the investigation is ongoing.
