For three weeks, the FBI has been chasing down tips and leads, trying to figure out what left one Border Patrol agent dead and another seriously injured along the U.S.-Mexico border in Texas.
But authorities are still stumped — they are no closer to finding concrete answers than they were right after finding the agents at the bottom of a deep ravine, ABC News was told.
“All we have done is rule out people,” one law enforcement source said.
Border Patrol Agent Rogelio Martinez died from head injuries and blood loss, while agent Stephen Garland also suffered serious head trauma. Garland has told authorities he can’t remember what happened that night, sources told ABC News.
The FBI has taken over the case, and on Saturday, FBI agents thought they were onto something: A confidential “source” claimed that within a group of undocumented immigrants recently smuggled into the United States were two people who “discussed their assault of the agents,” according to FBI documents filed in the case.
The FBI then identified both men — one of them in Odessa, Texas, and the other an alleged drug smuggler in Portales, New Mexico, according to an FBI affidavit filed in the case. FBI agents interviewed the alleged drug smuggler, who denied any involvement, and searched his car, the affidavit said. But agents didn’t find anything of significant value in the vehicle, according to two sources familiar with the matter.
Both men are no longer considered suspects in the case, the sources said. The alleged drug smuggler, however, has been arrested and charged with entering the country illegally, according to court documents.
