Mexico holds 2 in connection with US border agent shooting Oct. 2: Nicholas Ivie is seen in this undated photo provided by the Ivie family.AP MEXICO CITY - A Mexican law-enforcement official says federal police have arrested two men who may be connected with the fatal shooting of a U.S. Border Patrol agent this week just north of the Mexico/Arizona border. The official, who spoke on condition of anonymity because he was not authorized to release the information, said it remained unclear if there was strong evidence linking the men to the shooting of Agent Nicholas Ivie. Another agent was wounded in the attack. Ivie and two other agents were fired upon in a rugged hilly area about five miles north of the border as they responded to an alarm that was triggered on one of the sensors that the government has installed along the border.
