A federal judge in Mexico who handled cases against high-ranking members of criminal gangs has been shot dead along with his wife at their home in the western state of Colima, sparking outrage in the country’s legal community.

Though Mexico is plagued by growing drug-related violence and organized crime, the killing of a federal judge is unusual. Colima on the Pacific coast has become one of Mexico’s deadliest because of its strategic location as a crossroads for the international drug trade dominated in the area by the Sinaloa cartel and splinter groups.
