A Selma woman faces a charge of unlawful possession of a controlled substance after a routine traffic stop Thursday at Selma Avenue and Broad Street.

Selma police Sgt. Doug Stewart said officers noticed the driver, Shannon Oshields-Williams, acted suspicious “by making awkward movements and continuously reading into the passenger side and rear seat of her vehicle.”

Stewart said she gave permission for officers to search the vehicle and her purse.

“Officers discovered an aspirin bottle that contained what is believed to be methadone,” Stewart said.

Methadone is sued to relieve moderate-to-severe pain that has not been relieved by non-narcotic pain relievers. It is also used to prevent withdrawal symptoms i patients who were addicted to opiate drugs and are enrolled in treatment programs to stop taking the drugs.

Williams was released Friday on a $2,500 bond.
