Border Patrol Agent Robert Wimer Rosas Jr. was killed on July 23, 2009, while on patrol near Campo, California. At about 9:15 pm on the Shockey Truck Trail along the U.S.-Mexico border, he was ambushed after exiting his patrol vehicle and shot multiple times. Responding agents found him with several gunshot wounds; he died at the scene.

Three crossed into the United States, set up the ambush and lured Agent Rosas from his vehicle; two remained in Mexico as lookouts. After shooting him, the assailants stole his gear bag, handcuffs, firearm and night vision goggles. Four of the five suspects were later apprehended; a 17-year-old believed to have fired the fatal shots was sentenced to 40 years in prison.

Agent Rosas had served three years with the United States Border Patrol and left behind a wife, a 2-year-old son and an 11-month-old daughter. Who has additional information about the events on Shockey Truck Trail that night?
