SIERRA VISTA - A somber day in Sierra Vista as hundreds of friends, family and colleagues gathered to say goodbye to border patrol agent Nicholas Ivie.

The 30-year-old husband and father of two was shot and killed last week in a case of so-called friendly fire.

Ivie and two other agents responding to a tripped sensor, meant to detect smugglers near Naco.

Reportedly, Ivie fired first, wounding one comrade. Ivie then died in the return fire.

The service touched thousands; it was broadcast to LDS meeting houses across Southern Arizona, ensuring all who wanted to attend could.

They sang hymns and shared heartfelt sentiment with Nick Ivie's loved ones.

Aaron Kerr is both an agent, and Nick's neighbor.

"As we mourn with you over this immense personal tragedy, we also rejoice in the majesty of nick's life," said Kerr.

The church was standing room only, Arizona's Governor was also in attendance.

At times, holding back tears, Joel Ivie says his brother loved his job, and the remote desert he patrolled.

"Nick is one that lived his life by example," Ivie said.

He says Nick installed the sensor the three agent were responding to that night.

"Nick died in a beautiful place, and although it may have been a traumatic experience, he did die peacefully," he said.

Members of the Mormon church all their lives, Ivie says his brother Nick served a two year mission to Mexico, where he learned Spanish.

He'd use that knowledge to teach and serve others.

Ivie said, "look at all the good things that have come from Nick's life. Look at all of us here."

Agent Kerr says Nick always showed charity to others, leaving behind a legacy for his wife, children, church and country.
