The body of U.S. Border Patrol Agent Nicholas Ivie arrived at the Salt Lake City International Airport Tuesday night, and law enforcement officials gathered to escort Ivie to a mortuary in preparation for his funeral service.

Ivie was killed in a shooting in southeastern Arizona on Oct. 2 after two sets of agents approached each other in an area where a motion sensor had been tripped near the Arizona-Mexico border. The agents reportedly mistook each other for armed smugglers. Ivie, 30, apparently opened fire first and wounded one of the other agents, and then was killed in the return fire, reports say.

"All it is is a tragic accident," Ivie's brother Chris said. "Nothing more."

During a memorial service in Sierra Vista, Ariz., Nicolas Ivie's family and friends invited the agent who shot and killed him to sit and mourn with them, KSL reported.

"We don't have any anger in our hearts against the other agents involved in this," Chris Ivie said.

Ivie's funeral service in Utah will be held at the UCCU Center at Utah Valley University in Orem on Thursday. It begins at 11 a.m. and is open to the public. Ivie will be buried in the Spanish Fork Cemetery.
