Two Arrested in Border Killing

An anonymous Mexican Army officer says two suspects were arrested Wednesday in the killing of U.S. Border Patrol agent Nicholas Ivie, Reuters reports. Ivie was responding to a tripped ground sensor in the border area in Arizona. Another officer was injured and a third escaped what officials think may have been an ambush. The suspects are being held in a Mexican military facility just a few miles from the border, in Agua Prieta.
