KINGSPORT, Tenn. -

A traffic stop led to several charges for a Kingsport woman.

Kingsport Police say they pulled over Bianca Rodriguez Tuesday afternoon.

During their investigation, officers summoned K-9 Macho to the car, who alerted officers to the presence of narcotics. As a result, detectives searched Rodriguez's vehicle; we're told they found three rocks of crack cocaine, as well as valium tablets in the driver's seat.

Once Rodriguez was taken to the city jail, officers say a more thorough search revealed an additional rock of crack cocaine on her person.

Rodriguez is now charged with crack cocaine possession for resale and introduction of narcotics into a penal facility.
