The wife of a mayor whose police force turned 43 students over to a drug gang that allegedly killed them has been charged with organized crime and money laundering.

Maria de los Angeles Pineda's husband is former Iguala mayor Jose Luis Abarca. Her brothers were leading members of the Guerreros Unidos drug gang.

Federal prosecutor Tomas Zeron said Monday that Pineda has been charged with organized crime related to drug trafficking, and use of illicit funds. She has been transferred to a federal prison.

Abarca and Pineda were arrested Nov. 4 in Mexico City. Abarca was charged with organized crime, kidnapping and homicide.

The students disappeared Sept. 26 in Iguala, Guerrero. Only one of the students has been identified from charred bits of bone.
