A 19th suspect in a Southern Arizona cocaine trafficking operation has been arrested.

Norma Ruth Fouche of Phoenix was arrested Wednesday and is being held at the Maricopa County jail, Special Agent Ramona Sanchez, spokeswoman for the DEA, said Thursday afternoon.

The arrests this week were the culmination of a yearlong Drug Enforcement Administration investigation of a cocaine-trafficking organization operating in Cochise County, Sanchez said.

Two suspects are still being sought.

Suspects will face charges that include conspiracy to import, transport, sell and possess cocaine; money laundering; sale and transportation of a narcotic drug for sale; and use of a wire or electronic communication in a drug offense. All of the suspects are tentatively scheduled to be arraigned Tuesday in Pima County Superior Court.
