Mexico's Defense Secretary said on Friday that officials have identified men dressed in military garb who helped drug traffickers in Hudspeth County in January. And he says they are not soldiers.

Gerardo Clemente Vega told a Mexico City news conference the men involved in the January 23rd border incident are Jose Rodolfo Escajeda Escajeda, Alonso Escajeda Candelaria, Jaime Fernandez Jurado and Cesar Gandara. The four are still at large.

Vega says Escajeda Escajeda has been linked to drug traffickers in Chihuahua.

Hudspeth County Deputies spotted three vehicles driving in the United States along I-10, and began a chase which led back to the Rio Grande. One vehicle blew a tire - the driver ran back to Mexico. A second vehicle safely crossed the Rio Grande. A third became stuck in the river. That's when a military Humvee and armed men came to the rescue. Unable to tow the vehicle back across the river, they unloaded suspected drugs, and then set the vehicle on fire.

Hudspeth County Deputies report that they were confronted by up to 20 heavily armed gunmen in military uniforms on the river, and that some of those men crossed into the United States and began to flank them on both sides.

The discrepancy between the Defense Secretary naming four suspects, and the Deputies report that 20 were at the scene has not been rectified.
