Authorities have launched a manhunt in a remote area along the Arizona–Mexico border for suspects in a shooting that left one Border Patrol agent dead and another injured. The shooting occurred just before 2 a.m., when three agents were sent to an area near Naco and a ground sensor was activated. Authorities say that the third agent escaped unharmed. The murdered agent has been identified as 30-year-old Nicolas Ivie. Authorities are looking for three to four suspects, but officials say they may have fled to Mexico after the shooting.
