Two men start their trial Monday in Washington in connection with an ambush on two U.S. Immigration and Customs Enforcement agents in 2011 that wounded one and killed the other.
Court documents name Jesus Ivan Quezada Piña and Jose Emanuel Garcia Sota as the two facing murder and attempted murder charges for an attack on the agents on February 15. The two are suspected of opening fire on the agents' blue Suburban vehicle as they drove through the northern state of San Luis Potosi in Mexico.
Agent Jaime Zapata was killed in the attack and agent Victor Avila was wounded with gunshots in his leg.
Avila is from El Paso but was assigned to the Attache Mexico office.
Officials said Zapata and Avila were driving from Mexico City to the northern city of Monterrey on routine business when they were stopped and suspects opened fire on them.
San Luis Potosi has seen sporadic incidents of drug violence, but it borders two states where cartels are waging a bloody fight for territory.
Quezada and Garcia start opening statements in front of Judge Royce Lamberth Monday at 10 a.m. Eastern.
