Several garbage bags filled with harvested marijuana plants were discovered during a routine traffic stop Tuesday in Dawson County.

Ashley Seibert, 24, of Alpharetta, was charged with manufacturing marijuana, possession of marijuana, speeding and a tire requirement violation.

Dawson County Sheriff's spokesman Capt. Tony Wooten said the suspect was speeding when she was pulled over by Cpl. Randy Mullis on Hwy. 9 South.

Sheriff Billy Carlisle called the arrest a significant bust for the department and for Mullis.

"His training paid off that he knew what to look for to make this arrest. He did a good job," Carlisle said.

According to jail records, Seibert is being held at the Dawson County Detention Center with no bond.
