Sarah McKinnon, 33, of Cardinal Drive in Trenton, was arrested on Sept. 10 after officers found methamphetamine in her pants.
Parents were notified by the school that McKinnon would be out of the classroom and a substitute would fill her role.
McKinnon and her former brother-in-law, Steven McKinnon, of Pineview Drive in North Augusta, were arrested by North Augusta Public Safety officers in the early morning hours of Sept. 10 when officers spotted their blue Suzuki SUV stopped without any taillights along U.S. Hwy 25 and Edgewood Drive.
Steven admitted to officers that his license was suspended, but the officers' K-9 drug dog sniffed out drug paraphernalia during a search of the vehicle, including a glass pipe and scale.
A female deputy was called in to search McKinnon, where she found a silver tin near the teacher's crotch of her pants containing four clear plastic bags containing methamphetamine. Another bag also had three Xanax pills, according to the incident report.
Steven told officers that he made McKinnon hide the container on her so the drugs would not be found on him.
Both were arrested and booked at the Aiken County Detention Center on charges of possession with intent to distribute meth, possession of a controlled substance and possession of drug paraphernalia. Steven was also charged with driving under suspension.
According to district policy, McKinnon's administrative suspension will continue, pending resolution, and she will receive usual compensation through the term of the teaching contract. If there's no conviction, the suspension would end.
