 In this April 6, 2012, photo, former Navy SEAL and author of the book “American Sniper”, Chris Kyle poses in Midlothian, Texas. Kyle, 38, had left the Navy in 2009 after four tours of duty in Iraq, where he earned a reputation as one of the military's most lethal snipers. “Chad and Chris had taken a veteran out to shoot to try to help him,” said Travis Cox, a friend of Mr. Kyle’s. But on Saturday, far from a war zone, Mr. Routh turned on Mr. Kyle, 38, and a second man, Chad Littlefield, 35, shortly after they arrived at an exclusive shooting range near Glen Rose, Tex., about 50 miles southwest of Fort Worth, law enforcement authorities said Sunday. The insurgents never collected, and he returned home to become a best-selling author and a mentor to other veterans, sometimes taking them shooting at a gun range near his Texas home as a kind of therapy to salve battlefield scars, friends said.
– The former Navy SEAL sniper shot dead alongside a friend at a Texas shooting range yesterday appears to have been killed by a troubled Iraq War veteran he was trying to help, authorities say. Travis Cox, director of a nonprofit veterans' organization that American Sniper author Chris Kyle helped found, says Kyle and his friend were helping Eddie Ray Routh deal with post-traumatic stress disorder, the AP reports. Routh, 25, has been charged with both murders. Kyle "served this country with extreme honor, but came home and was a servant leader in helping his brothers and sisters dealing with post-traumatic stress disorder," Cox tells the New York Times. "Everyone has their own inner struggles, but he was very proactive about the things he was dealing with." The local sheriff says Routh's mother may have reached out to Kyle for help with her son. Investigators, who believe Routh killed both men with a semi-automatic handgun, say he has not made any comments that would indicate a motive.
