A former Marine has been charged with three counts of murder in the killing of former Navy SEAL and "American Sniper" author Chris Kyle, the most deadly sniper in U.S. history, and another man at an Erath County, Texas, gun range, police said.
"We have lost more than we can replace. Chris was a patriot, a great father, and a true supporter of this country and its ideals. This is a tragedy for all of us. I send my deepest prayers and thoughts to his wife and two children," Scott McEwen, co-author of "American Sniper: The Autobiography of the Most Lethal Sniper in U.S. Military History," said in a statement to ABC News.
Remembering Kyle for the number of Iraqi insurgents he killed misstates his legacy, McEwen said.
"His legacy is not one of being the most lethal sniper in United States history," McEwen said. In my opinion, his legacy is one of saving lives in a very difficult situation where Americans where going to be killed if he was not able to do his job."
Kyle and a neighbor of his were shot at a gun range in Glen Rose while helping a former Marine who was recovering from post traumatic stress syndrome, ABC affiliate WFAA-TV in Dallas reported.

The suspect, identified as Eddie Ray Routh, 25, was arrested in Lancaster, Texas, after a brief police chase, a Lancaster Police Department dispatcher told ABC News. Routh was driving Kyle's truck at the time of his arrest, police said.
Routh was arraigned Saturday evening on one count of capital murder and two counts of murder. He was brought to the Erath County Jail this morning and was being held there today on a combined $3 million bond, Officer Kyle Roberts said.
Investigators told WFAA that Routh is a former Marine said to suffer from post-traumatic stress syndrome.
Kyle helped found a nonprofit that provides at-home fitness equipment for emotionally and physically wounded veterans, but the director of the foundation said Kyle and Routh had not met through the organization.
"Chris was literally the type of guy if you were a veteran and needed help he'd help you," Travis Cox, the director of FITCO Cares, told The Associated Press. "And from my understanding that's what happened here. I don't know how he came in contact with this gentleman, but I do know that it was not through the foundation."
Authorities identified the other man who was killed with Kyle as 35-year-old Chad Littlefield, who Cox said was Kyle's neighbor and friend.

Kyle, 38, served four tours in Iraq and was awarded two Silver Stars, five Bronze Stars with Valor, two Navy and Marine Corps Achievement Medals, and one Navy and Marine Corps Commendation.
From 1999 to 2009, Kyle recorded more than 150 sniper kills, the most in U.S. military history.
After leaving combat duty, Kyle became chief instructor training Naval Special Warfare Sniper and Counter-Sniper teams, and he authored the Naval Special Warfare Sniper Doctrine, the first Navy SEAL sniper manual. He left the Navy in 2009.
"American Sniper," which was published last year by William Morrow, became a New York Times best seller.
