John Richard Johnson, 27, of Grovetown, and Dena Williams, 37, of Hephzibah, are in jail on charges of manufacturing of methamphetamine, according to the department.
About 12:25 p.m. the officer pulled over a Cadillac with Georgia tags for an improper turn near the intersection of York Street and Hampton Avenue, police said.
Sgt. Jake Mahoney, a spokesman for the department, said that the officer noticed the couple acting strange and that a pill bottle fell out of the glove compartment.
The officer requested a K-9 unit. The dog alerted the officers to the possible presence of drugs.
“A search of the vehicle identified the precursors and ingredients used in the manufacturing of methamphetamine,” Sgt. Mahoney said.
