Nicholas J. Ivie knew the terrain in the southern Arizona desert southeast of Tuscon along the Mexican border was among the most active stretches monitored by the U.S. Border Patrol.

“Nick has always been involved in areas with high traffic,” said Brandon Judd, a fellow Border Control agent who worked with Ivie. “He embraced it.”

Ivie, 30, was killed by gunfire Tuesday after responding to a sensor alarm near Highway 80 about seven miles east if Bisbee, according to the Border Patrol. One other agent sustained non-life threatening wounds.

Ivie lived with his wife and their two young daughters in Sierra Vista, Az., where he was involved with the community and the Church of Jesus Christ of Latter-Day Saints.

Ivie grew up in Provo, Utah, and joined the U.S. Border Patrol in January 2008. After graduating from the border patrol academy, he was assigned to the Naco Border Patrol Station.

The station was recently renamed after Brian Terry, a Border Patrol agent fatally shot on duty in December 2010.

Ivie “was just outstanding in every regard,” said Judd. “He wanted to go to work every day. He loved his job, loved people, and didn’t shy away from talking to people.”

Ivie was friendly and outgoing, Judd added. “He treated everybody the same, whether they were liked or not liked.”

“Tuscon sector mourns the loss of one of our own,” acting chief patrol agent Manuel Padilla said in a statement. “It stands as a reminder of the dangers that agents . . . face very day.”

President Obama expressed thanks for Ivie’s “selfless service to his nation” in a call to his family Tuesday, according to a White House statement.
