The wife of the former mayor of a Mexican city where 43 students disappeared will be tried on organized crime charges.

The federal judiciary council said Monday that a court ruled there was enough evidence to try Maria de los Angeles Pineda on charges she engaged in organized crime to traffic drugs and launder money.

Pineda is the wife of Jose Luis Abarca, who is on trial for organized crime, homicide and kidnapping.

Abarca was mayor of Iguala, in Guerrero state. In September he allegedly ordered local police to detain the students and turn them over to the Guerreros Unidos drug gang, which apparently killed them.

The council said Pineda belonged to the gang since 2005 and probably handled $937,000 (13, 722, 849 pesos) for Guerreros Unidos.
