CIUDAD JUAREZ, Mexico (CBS/AP) Four Americans were recently shot to death in separate attacks in the border city of Ciudad Juarez, Mexican authorities said Monday.
Chihuahua state prosecutors' spokesman Arturo Sandoval said Edgar Lopez, 35, of El Paso, Texas, was killed Sunday along with two Mexican men when gunmen opened fire on a group standing outside a house.
On Saturday, a 26-year-old U.S. woman and an American boy were slain shortly after crossing an international bridge from El Paso. Giovanna Herrera and Luis Araiza, 15, were shot to death along with a Mexican man traveling with them just after 11 a.m., Sandoval said.
Sandoval said authorities also identified a 24-year-old woman killed Friday inside a tortilla shop as Lorena Izaguirre, a U.S. citizen and El Paso resident. A Mexican man was also found dead in the store.
Sandoval did not provide any information about possible motive in any of the slayings.
U.S. State Department spokesman P.J. Crowley confirmed three of the killings but did not have any information about Izaguirre. He said officials had been in touch with the victims' families but offered no other details.
Ciudad Juarez has become one of the world's deadliest cities amid a turf war between the Sinaloa and Juarez drug cartels. More than 2,000 people have been killed this year in the city, which is across the border from El Paso.
