Federal agents have arrested a number of members of the Barrio Azteca drug gang in Mexico overnight, after having tied the group to the killing of a U.S. consulate worker and her husband, according to people familiar with the case.

Lesley Enriquez and her husband were gunned down in March 2010. Mexican investigators said months later that a captured drug-gang enforcer claimed to have ordered the slaying because Ms. Enriquez allegedly helped provide visas to a rival gang. At the time, federal authorities said the motive for the killing was unknown.
The attack on the Enriquez couple came at almost the same time as a third killing in which the husband of a Mexican employee of the U.S. consulate was gunned down. That raised concerns that U.S. government personnel were being targeted in drug-related violence. Those concerns were revived last month when an Immigrations and Customs Enforcement agent was gunned down on a roadside in Mexico.
Ms. Enriquez was pregnant when she was killed. The couple’s infant daughter was in the car at the time of the shooting but was not injured. Police who responded to the crime scene found the child crying in the back seat.
