SAN DIEGO (CN) - A fourth defendant was sentenced Thursday to 40 years in prison for the 2009 robbery and murder of Border Patrol Agent Robert Rosas Jr.
Emilio Samyn Gonzales-Arenazas, 25, pleaded guilty in July 2011, the U.S. Attorney's Office said in a statement announcing his sentence.
Gonzales, of Mexico, admitted "he was one of five armed individuals who conspired to rob a Border Patrol agent of his night vision device, which resulted in Agent Rosas being fatally shot during a struggle. He pleaded guilty to murder of a federal officer committed in perpetration of a robbery and unlawful confinement," prosecutors said.
They killed and robbed Rosas on July 23, 2009, near Campo.
Three other defendants have been sentenced to terms of 40, 55 and 56 years.
The last defendant, Jose Juan Chacon Morales, is a fugitive. The United States has offered a reward of up to $100,000 for information leading to his arrest.
