In July 2009, U.S. Border Patrol Agent Robert Rosas, Jr. was ambushed by five Mexican nationals, three of which entered the United States illegally to assault Rosas through a hole in the border fence and then quickly fled back over the border.
Thursday, 28-year-old Marco Rodriguez-Perez entered into a plea agreement after being extradited to the United States from Mexico in October 2011. In the agreement, Rodriguez-Perez admitted to ambushing Agent Rosas while he was on-duty, in uniform and responding to a remote area near Campo, California. The goal was to rob Rosas of his night vision goggles and they killed Agent Rosas in the process. More from the FBI:
