A Summerville Police officer on patrol on Martin Street last week noticed a vehicle driving in the wrong lane of traffic.  The officer performed a traffic stop and the male driver appeared to be extremely nervous and showing signs of impairment.  The officer asked the driver if he had taken any drugs and the man admitted to having “smoked something” a short time before.  Police found suspected methamphetamine and a glass pipe under the hood of the man’s vehicle.  After performing a field sobriety test, thirty-one-year-old Justin Tolbert Pettyjohn was arrested and charged with possession of methamphetamine, possession of drug related objects and was booked into the Chattooga County Jail.
