PHOENIX (AP) - The family of a U.S. Border Patrol agent shot and killed along the Mexico/Arizona border says the man was a devoted Mormon who developed a love for the Mexican people and culture while serving on a mission in Mexico City.

Agent Nicholas Ivie and two other agents were fired upon Tuesday about five miles north of the border as they responded to an alarm triggered by a border sensor. The wounded agent was released from the hospital after undergoing surgery. The third agent wasn't injured.

A Mexican law enforcement official says federal police have arrested two men who may be connected with the shooting but authorities aren't saying much else.

Ivie's family described the 30-year-old as a loving father and husband who loved his job as a Border Patrol agent.
