PHOENIX (AP) — A Mexican man accused in the killing of a U.S. Border Patrol agent has admitted he was part of a crew that sneaked into the United States to find marijuana smugglers to rob at the time of the fatal shooting.

Manuel Osorio-Arellanes pleaded guilty Tuesday in the death of Agent Brian Terry. He said the group got into the country a week before the shootout that killed Terry, and stashed guns and food supplies on the U.S. side of the border.
