Shooters broke into the house in a mountainous area known as Sierra Negra early on Friday morning and killed five women, four men and two girls, before fleeing on foot, according to the state attorney general's office. Two other girls with chest and stomach wounds were taken to a hospital in nearby Tehuacan. Vicente Lopez de la Vega, a mayor from the city of Coxcatlan, said it was not immediately clear if the shooting was the result of a family feud or organized crime.
