 A Mississippi sheriff's deputy was shot and killed during a traffic stop by a suspect who was killed by police following a car chase, authorities said George County Deputy Jeremy Malone was killed after he stopped a vehicle around 5.15 p.m. Thursday on US Route 98 in Rocky Creek, George County Sheriff Mitchell Mixon said in a statement. Malone was the largely rural county's second emergency responder killed over the past week, following the death of a medical technician in a roadside accident. In nearby Alabama, the suspect, who was not immediately identified, led police on a chase out of the county. The suspect was killed by police as the pursuit ended, Mixon said.
