The drug war that has consumed Mexico claimed the lives of three people with ties to the American consulate there Sunday. It added to the already grisly tally of nearly 50 people killed in apparent gang violence over the weekend in Mexico. American citizens Lesley A. Enriquez, 35, and her husband, Arthur H. Redelf, 34, were two of the people murdered on Sunday, while their baby survived in the back seat of their car on the bridge between violence-wracked Ciudad Juarez and El Paso, Texas. Enriquez worked for the U.S. consulate, while Redelf was a detention officer at an El Paso jail. The third person killed was the husband of a Mexican citizen employee of the consulate. Their two young children were wounded. President Barack Obama was "deeply saddened and outraged," according to the White House and Mexican President Felipe Calderon has promised an investigation.
