EL CENTRO, CA – JULY 31: Memorial Services take place for Border Patrol Agent Robert Rosas, the victim of the first fatal shooting of a US Border Patrol agent in more than a decade, on July 31, 2009 in El Centro, California. The 30-year-old father of two small children was killed on July 23 when he tracked a suspicious group of people alone in the bush-covered hills along the US-Mexico border near the rural town of Campo, some 60 miles east of San Diego, California. Rosas had been with the agency for three years. (Photo by David McNew/Getty Images)
