Two Border Patrol Agents Shot in Arizona, One Killed (Update: Agent Identified)

The agents were shot while patrolling on horseback in Naco, Ariz., at about 1:50 a.m. MST Tuesday, the Border Patrol said in a statement.

The agents who were shot were on patrol with a third agent, who was not harmed, according to George McCubbin, president of the National Border Patrol Council, a union representing about 17,000 border patrol agents.

The shooting occurred after an alarm was triggered on one of the many sensors along the border and the three agents went to investigate, said Cochise County Sheriff's spokeswoman Carol Capas.

Authorities have not identified any suspects, Capas said. It is not known whether the agents returned fire, she said.

UPDATE:

KGUN-TV has the name of the agent:

Customs and Border Protection identified the agent killed as Nicolas Ivie, 30, a native of Provo, Utah. He worked for Border Patrol since January 2008.

Carol Capas with the Cochise County Sheriff's Office told KGUN9 that three Border Patrol agents were walking up a trail when the gunfire occurred. One agent was killed, one was injured and another was left unharmed.
