CIUDAD JUAREZ, Mexico—Suspected drug gangsters chased down and opened fire on two white SUVs carrying families of U.S. consular employees from a children's party, killing three adults and and injuring two children in this violent border city, officials said Monday.
An infant in a car seat survived a burst of bullets that killed her American parents.
Mexican authorities put suspicion on the Aztecas street gang - a group allied with the "La Linea" enforcement arm of the Juarez drug cartel. They said that was based on "information exchanged with U.S. federal agencies."
But the reason for the attacks remained unclear.
All three victims had attended a children's party hosted by another consular employee shortly before the attacks, said the FBI spokeswoman in El Paso, Andrea Simmons.
"There is no information that the victims were specifically targeted" because of their work with the U.S. Consulate, she said, though the investigation is continuing.
Both the American couple and the Mexican man who was killed were traveling in similar vehicles - white sport utility vehicles.
The U.S. consulate in Ciudad Juarez, shut for Monday's Mexican national holiday, also will be closed on Tuesday as "a way for the community to mourn the loss" of the victims, said consulate spokesman Silvio Gonzalez. It was the second U.S. border consulate closed because of violence in the last month. The consular office in Reynosa, across from McAllen, Texas closed for several days in late February because of gun battles in the area.
Several U.S. citizens have been killed in Mexico's drug war, most of them people with family ties to Mexico. It is very rare for American government employees to be targeted, although attackers hurled grenades at the U.S. consulate in the northern city of Monterrey in 2008.
The atmosphere of violence in Juarez had been creeping closer to U.S. offices for some time: on Friday, the consulate put a bar just around the block from its office off limits to U.S. government personnel "due to security concerns."
The State Department said it would compensate U.S. government employees at Ciudad Juarez and five other U.S. consulates in northern Mexico who decide to send family members out of the area because of concerns about rising drug violence. The cities are Tijuana, Nogales, Nuevo Laredo, Monterrey and Matamoros.
The dependents - estimated to be several hundred - will get a 30-day special housing allowance, which could be renewed for additional periods.
State Department spokesman P.J. Crowley said the decision was taken earlier, based on a broader pattern of violence in the region. The State Department also urged U.S. citizens to delay unnecessary travel to parts of the Mexican states of Durango, Coahuila and Chihuahua.
The consulate employee and her husband, both U.S. citizens, were killed in their car near the Santa Fe International bridge linking Ciudad Juarez with El Paso, Texas.
The woman was shot in the head, while her husband suffered wounds in his neck and arm. Their baby girl, who appeared to be about 1 year old, was found unharmed in the back seat, said Vladimir Tuexi, a spokesman for the Chihuahua state prosecutors office.
The pair was identified as consular employee Lesley A. Enriquez, 35, and her husband, Arthur H. Redelfs, 34, by Robert Cason, Redelfs' stepfather. Redelfs was a detention officer at the El Paso County Jail, he said. Enriquez's family is prominent in Ciudad Juarez; her father was once honorary consul for Belgium.
Tuexi said the baby was in the custody of Mexican social services.
Officials confirmed that Enriquez was pregnant when she was killed.
