Three teenage boys—two of them American citizens—were killed at a car dealership in Ciudad Juarez, Mexico on Saturday. They were aged 15 to 17; one was found dead in a white Jeep, and the other two were found dead in a courtyard. One of the boys, Carlos Mario Gonzalez Bermudez, lived in Mexico and crossed the border each day for school. Police are unsure of what the motive was in the killings. There were two other triple homicides in Juarez last weekend, each of which cost a teenager his life.
