The FBI and witnesses tell the Associated Press that Mexican security forces chased away U.S. agents at gunpoint after a Border Patrol officer shot and killed a 15-year-old Mexican boy on the banks of the Rio Grande. The FBI said the boy was among a group throwing rocks as agents on the U.S. side of the border detained suspected illegal immigrants.
U.S. officials said the unidentified agent was defending himself Monday evening near the Paso Del Norte bridge, across the border from Ciudad Juarez. He fired several times, striking Sergio Adrián Hernandez Guereca once in his face, the FBI said. Hernandez will be buried tomorrow.
A 16-year-old relative told AP that not long after Hernandez was shot, Mexican federal agents arrived and pointed their guns at the U.S. agents as they waded into the mud, threatening to kill them if they crossed the border. The Americans retreated.
A U.S. official said video shows the Border Patrol agent did not enter Mexico.
AP offers other developments:
• Arturo Sandoval, a spokesman for the Chihuahua state Attorney General's office, said a spent .40-caliber shell casing was found near the body — raising the question of whether the fatal shot was fired inside Mexico, although he did not explicitly make that allegation. That would violate the rules for Border Patrol agents, who are supposed to stay on the U.S. side of the border.
• A U.S. official said the video also shows what seem to be four Mexican law enforcement officers driving to the edge of the dry but muddy bed of the Rio Grande, walking across to the U.S. side, picking up an undetermined object and returning to Mexico near the area where the boy's body was. Like their U.S. counterparts, Mexican law officers are not authorized to cross the border without permission.
The agent has been assigned to desk duty pending the outcome of the investigation, which the FBI is heading.
Mexican President Felipe Calderon said his government "will use all resources available to protect the rights of Mexican migrants."
Less than two weeks ago, Mexican migrant Anastasio Hernandez, 32, died after a Customs and Border Protection officer shocked him with a stun gun at the San Ysidro border crossing that separates San Diego and Tijuana, Mexico. The San Diego medical examiner's office ruled that death a homicide.
