Susana Rodriguez, 42, was arrested Wednesday following a raid at a residence on the 100 block of West Seventh Street.
Alice police officers with the assistance of the Duval County Sheriff's deputies and the Central South Texas Criminal Investigation Unit entered the residence to find two occupants.
Rodriguez was detained as officers searched the home and a vehicle on the property.
Seven bags of cocaine that were ready for sale, a bag of marijuana, scales, drug paraphernalia and packaging material were discovered and confiscated from Rodriguez's bedroom.
The case is under investigation.
"We had been looking at this individual for awhile," said Lt. Luis Barrera. "She is a suspected street level dealer. We will continue to work on the narcotic aspect (of crime) making our city a safer place."
Rodriguez was transported to the Jim Wells County jail. She was charged with possession of marijuana, and manufacturing and delivery of a controlled substance.
