U.S. Border Patrol Agent Robert Rosas was ambushed and killed by five smugglers seeking to steal his night-vision goggles, according to a second suspect who has provided details of the crime in a plea agreement.
Emilio Gonzales pleaded guilty to murder of a federal officer in court and faces life in prison when he is sentenced Oct. 17. The suspects had lost night-vision goggles they use in smuggling operations, and were seeking a second pair.
