Riles and Johnson are charged with murder in an Austell railyard shooting.

Murder charges and a jail hold are accusations. They are not convictions. Cobb County police arrested Riles, 26, and Johnson, 28, around 2:30 a.m. Thursday, Sept. 24, 2026, in the fatal shooting of Norfolk Southern contractor Curdravious Clark, 27, and both men are held without bond.

On Sept. 14, 2026, about 10 p.m., Clark was shot at the Norfolk Southern facility in the Whitaker Intermodal Terminal area at 6000 Dr. Luke Glenn Garrett Jr. Memorial Highway in Austell, Cobb County, Georgia. FOX 5 Atlanta reported the time as about 10:04 p.m. First responders found him struck by gunfire. He was taken to Wellstar Cobb Medical Center, where he died. WSB-TV reported he was found shot to death in the parking lot, and that a witness said he had just shown up for work when he was shot multiple times. Suspects allegedly left the scene in a vehicle. Those are reported facts of the death. They are not a finding that either man fired.

FOX 5 Atlanta reported the arrests around 2:30 a.m. Thursday. Riles is also reported as Michael Riles. Johnson is also reported as Keondre Johnson. Both are held without bond at the Cobb County Adult Detention Center. The Cobb County Police Major Crimes Unit took the case at the Austell Police Department's request. Motive, and how police tracked the suspects, have not been publicly detailed. The investigation remains active. The charging captions differ slightly by outlet. FOX 5 reported felony murder, aggravated assault, and several weapons offenses. WSB-TV, citing warrants, reported murder, aggravated assault, possession of a firearm during the commission of a crime, and possession of a firearm by a felon. It does not invent a single charging sheet. All defendants are presumed innocent until proven guilty in a court of law.
