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 across the country’s legal community.

Though Mexico is plagued by growing drug-related violence and organized crime, the killing of federal judges is unusual. The state of 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.
