A forty-seven-year-old woman and a fifty-nine-year-old man were arrested late last week after a traffic stop in Summerville.  Summerville Police say that they stopped the vehicle because the driver was not maintaining a single lane.  While speaking with the driver, identified as Scott Blake Johnson, officer noticed that both he and his passenger were acting very nervous.  After receiving consent to search the vehicle, officers found suspected methamphetamine.  Neither Johnson, nor the passenger – Pamela Marie Fore – would take responsibility for the drugs.  They were both charged with possession of methamphetamine.  Johnson was also charged for failure to maintain a single lane and operation of an improperly equipped vehicle.
