From the KJZZ newsroom, I’m Steve Goldstein. Homeland Security Secretary Janet Napolitano will be in Arizona today to express her condolences to the family of Nicholas Ivie, the U.S. Border Patrol agent shot and killed this week just north of the Arizona-Mexico border. Napolitano will also meet with law enforcement authorities in Bisbee about the investigation into the agent's death. Mexico’s federal police have arrested two men who may be connected with the shooting that left Agent Ivie dead and a second agent injured.
