A state government in southern Mexico found itself playing middleman in negotiations involving a gang of drug traffickers who already released a kidnap victim and a band of armed, angry citizens who briefly held a crime boss’ mother seeking to take back control of their lawless, opium-country town.

The Guerrero state government sent police to spirit away Maria Felix de Almonte Salgado, the mother of drug gang boss Raybel Jacobo de Almonte, known as “El Tequilero,” after residents of the town of Totolapan got a kidnapped businessman back from the gang in return.
