() Jeff Kyle, the brother of former Navy SEAL sniper Chris Kyle, issued a statement Monday regarding Kyle’s recent shooting death on behalf of the Kyle and Littlefield families. Suspect Eddie Routh allegedly shot and killed Kyle, 38, and his friend Chad Littlefield at Rough Creek Lodge in Glen Rose, Texas on Saturday.

“My name is Jeff Kyle. I’m here representing my family, the Kyle family, and also the Littlefield family. I am reading a prepared statement prepared by the Kyle family and Littlefield family,” Kyle began.

“Chris Kyle and his trusted friend, Chad Littlefield, were tragically killed on Saturday, February 2, 2013, by a troubled veteran whom they were trying to help,” Kyle said. “Chris lived by a professional motto: ‘It is our duty to serve those who serve us.’ And he and Chad died honoring this creed.”

He went on: “Above all else, Chris was a unique individual, an amazing loving father, husband, son, brother, friend and devout Christian who had a profound effect on the lives of those that he touched. Chris was publicly known for being the president of Craft International and the author of the best-selling book ‘American Sniper.’ Chris, a former Navy SEAL, served four combat tours in operation Iraqi Freedom and elsewhere.”
