An Arizona woman has pleaded guilty to federal narcotics trafficking charges in New Mexico.
Prosecutors say 27-year-old Serina Josephina Rivera, of Sells, entered her plea Thursday in federal court in Albuquerque.
Rivera and a woman from Phoenix were arrested in April 2014 and charged in a criminal complaint with possession of methamphetamine and heroin with intent to distribute in Bernalillo County.
New Mexico State Police say they recovered seven bundles containing nearly six pounds of methamphetamine and three pounds of heroin that was concealed in a vehicle pulled over for a traffic stop.
Prosecutors say the women were driving the drugs from Phoenix to Dallas, Texas.
They say Rivera faces up to 20 years in prison when she's sentenced.
The sentencing hearing hasn't been scheduled yet.
