Our thoughts and prayers are with the families of two U.S. Border Patrol Agents killed in the line of duty today. The two agents were killed during an incident involving a train in Arizona early this morning as they were positioning themselves on a road north of some other agents who were trying to capture a group of suspected illegal immigrants.

Hector Clark, 39 and Eduardo Rojas, Jr., 35, were on-duty driving an unmarked official car when it was struck by a 90-car freight train at a rail about nine miles west of Gila Bend.

Agent Clark began his career with the U.S. Border Patrol on August 20, 2001. After graduation from the Border Patrol Academy, he was assigned to the El Centro Sector and was serving as a Lead Border Patrol Agent in the Yuma Sector at the time of his death. Agent Clark was a native of Yuma, Ariz., and is survived by his wife and two children.

Agent Rojas entered the U.S. Border Patrol on April 9, 2000, and was assigned to the Yuma Sector. At the time of the accident, he was serving as a Lead Border Patrol Agent in the Yuma Sector. Agent Rojas was a native of El Paso, Texas, and is survived by his wife and two children.
