 Former Navy SEAL and "American Sniper" author Chris Kyle was fatally shot along with another man Saturday on a central Texas gun range, a sheriff told local newspapers. 
 
 Erath County Sheriff Tommy Bryant said Kyle, 38, and a second man were found dead at Rough Creek Lodge's shooting range west of Glen Rose, according to the Fort Worth Star-Telegram and Stephenville Empire-Tribune. Glen Rose is about 50 miles southwest of Fort Worth. 
 
 Bryant did not immediately return phone calls to The Associated Press seeking comment late Saturday and early Sunday. A woman who answered the phone at the lodge where the shooting occurred declined comment and referred calls to the sheriff's office. 
 
 Investigators did not immediately release the name of the second victim, according to the newspapers. 
 
 Witnesses told sheriff's investigators that a gunman opened fire on the men around 3:30 p.m. Saturday, then fled in a pickup truck belonging to one of the victims, according to the Star-Telegram. The newspapers said a 25-year-old man was later taken into custody in Lancaster, southeast of Dallas, and that charges were expected. 
 
 Lancaster police did not immediately return calls for comment. 
 
 The motive for the shooting was unclear. 
 
 Kyle wrote the best-selling book, "American Sniper: The Autobiography of the Most Lethal Sniper in U.S. Military History," detailing his 150-plus kills of insurgents from 1999 to 2009. 
 
 Kyle was sued by former Minnesota Gov. Jesse Ventura over a portion of the book that claims Kyle punched Ventura in a 2006 bar fight over unpatriotic remarks. Ventura says the punch never happened and that the claim by Kyle defamed him. 
 
 Kyle had asked that Ventura's claims of invasion of privacy and "unjust enrichment" be dismissed, saying there was no legal basis for them. But a federal judge said the lawsuit should proceed. Both sides were told to be ready for trial by Aug. 1. ||||| Former Navy Seals Sniper Chris Kyle, is pictured in this handout photo from Harper Collins.

 Eddie Ray Routh is pictured in this booking photo provided by the Erath County Sheriff’s Office. Routh is a suspect in the shooting and killing of former Navy SEAL Sniper Chris Kyle. 
 
 The man accused of gunning down former U.S. Navy SEAL Chris Kyle, a prominent military sniper, and a second man at a Texas shooting range has been arraigned on two counts of capital murder, the Texas Department of Public Safety said on Sunday. 
 
 Eddie Ray Routh, 25, was accused of killing Kyle, 38, and Chad Littlefield, 35, a neighbor of Kyle, on Saturday afternoon at the Rough Creek Lodge, about 50 miles southwest of Fort Worth, the department said. 
 
 "They were shot at close range," said department spokesman Sergeant Lonny Haschel said. 
 
 Kyle, considered one of America's deadliest snipers after killing 160 people during his career as U.S. Navy SEAL sniper, wrote the book "American Sniper" about his military service from 1999 to 2009. 
 
 Routh, described in local media reports as a former Marine who suffered from post traumatic stress syndrome (PTSD), was arrested at his Lancaster, Texas home several hours after the shooting, having led police on a chase in his pickup truck. 
 
 "He was taken into custody after a brief pursuit," Haschel said. 
 
 According to a posting on a website run by members of the Special Operations Forces community, Kyle had been volunteering his time to help Marine Corps veterans suffering from PTSD and mentoring them. 
 
 "Part of this process involved taking these veterans to the range," said the posting on SOFREP.com. 
 
 WFAA-TV in Dallas-Fort Worth reported that the two men had taken Routh to the shooting range for the day to help him deal with his PTSD. 
 
 Routh was arraigned at the Lancaster municipal jail on Saturday on two counts of capital murder, a spokesman for the department of public safety said. The Erath County Sheriff's Office planned a news conference later on Sunday. 
 
 "It just comes as a shock and it's staggering to think that after all Chris has been through, that this is how he meets his end, because there are so many ways he could have been killed" in Iraq, Scott McEwen, who wrote the book with Kyle, told Reuters. 
 
 Kyle served four combat tours of duty in Iraq and elsewhere, and he won two Silver Stars and five Bronze Stars for bravery, according to his book. 
 
 After leaving the Navy, Kyle founded Craft International, a firm that provided combat and weapons training to military, police, corporate and civilian clients. 
 
 Kyle is the co-author of another book coming out in May titled "American Gun - A History of the U.S. in Ten Firearms." 
 
 In the wake of the slayings of 20 children and six adults at a school in Newtown, Connecticut in December, Kyle was interviewed in January about rising calls for curbing U.S. gun violence. He told the website guns.com he favored arming teachers who have been screened and trained and spoke against restrictions on gun owners. 
 
 (Reporting by Barbara Goldberg; Editing by Ellen Wulfhorst and Will Dunham) ||||| A former Navy SEAL known for claiming a record number of sniper killings in Iraq was one of two men shot dead at a Texas gun range, allegedly at the hands of a fellow military veteran, officials say. 
 
 Chris Kyle, the author of the best-selling "American Sniper," and Chad Littlefield, Kyle's friend, were gunned down Saturday afternoonon the grounds of the expansive Rough Creek Lodge and Resort in Glen Rose, Texas, southwest of Fort Worth, law enforcement officials said. 
 
 About four hours afterward, and 90 miles from where those two men's bodies were found by a hunting guide, authorities arrested suspect Eddie Ray Routh, 25, on a capital murder warrant. 
 
 Routh's family members could not be reached immediately for comment Sunday. No attorney has made a public statement on his behalf. 
 
 Erath County Sheriff Tommy Bryant said Sunday that he believes the suspect is in the process of seeking a court-appointed attorney. 
 
 While Routh's sister said he had admitted shooting Kyle and Littlefield, he didn't explain to her why he did it, Bryant said. Routh isn't believed to have confessed to local authorities about killing the two men. The motive for the killings is unclear. 
 
 "I don't know that we'll ever know," Erath County Sheriff's Capt. Jason Upshaw said Sunday. "(Routh) is the only one that knows that." 
 
 Sheriff: Suspect spent four years in Marines 
 
 The Rough Creek Lodge is a large facility that draws couples getting married, business people using its conference center and families looking for a getaway. Hunting and shooting sports are some of the many recreational options available on its grounds. 
 
 Kyle, Littlefield and Routh were three such visitors, arriving together around 3:15 p.m. (4:15 p.m. ET) Saturday and proceeding to a shooting range within the resort's 11,000 acres, Bryant told reporters Sunday. The range is in a "very remote part" of the sprawling complex, Upshaw explained. 
 
 "So there wasn't anybody anywhere close to that," he said, explaining there are no known witnesses. 
 
 The first sign something was wrong came when a hunting guide tied to the facility found 38-year-old Kyle and 35-year-old Littlefield -- both unconscious -- around 5 p.m., Bryant said. 
 
 He went to the lodge and called 911. Law enforcement officers followed up and found the bodies but no sign of Routh. He had taken off in Kyle's black Ford pickup, the Erath County sheriff said. 
 
 Around the time an all-points bulletin went out for that truck, authorities got a call from Routh's sister, who reported that her brother had driven about 65 miles to her home in Midlothian, Texas, and admitted to shooting Kyle and Littlefield. 
 
 Routh left his sister's house, and police eventually caught up with him -- and the truck -- shortly before 8 p.m. at his home in Lancaster, a Dallas suburb some 90 miles northeast of the shooting scene. While talking with authorities outside, he'd somehow gotten back in the truck and sped away. 
 
 Authorities chased him and finally stopped him, around 9 p.m., after spiking his tires some four to six miles down the road, according to Bryant. 
 
 Routh did not struggle with officers as they were arresting him, Bryant said. On Sunday morning, he was arraigned on murder charges and ordered held on $3 million bond. 
 
 After that, Routh sat in a jail cell "all by himself," separated from the rest of the inmate population and watched closely by guards, according to Bryant. 
 
 So who is Eddie Ray Routh? 
 
 The sheriff said that Routh spent four years in the Marines. He is believed to have left the service in 2010, according to a U.S. military official who spoke on condition of anonymity because of the sensitivity of the situation. The official did not have information on where Routh served or whether he took part in combat. 
 
 Public records show Routh previously lived at Camp Lejeune in North Carolina, though his latest address was in Lancaster, Texas. 
 
 At the time of shooting, he was unemployed. Bryant said that Routh's mother, a longtime schoolteacher, "may have reached out to Mr. Kyle to try and help her son." 
 
 'He led by example,' Kyle's friend says 
 
 Kyle learned to shoot on hunting trips with his father, then went on to serve four combat tours in Iraq with the SEALs, though his official biography notes he also worked with Army and Marine units. He received two Silver Stars and other commendations before leaving the Navy in 2009 -- claiming that, in his years as a sniper, he'd killed more than 150 people, which he called a record for an American. 
 
 In the interview with Time magazine (like CNN, a part of Time Warner), Kyle said he did not regret any of his kills. He also said he was "comfortable" with the possibility that that part of his life might be over. 
 
 He added, "I'm a better husband and father than I was a killer." 
 
 After having worked under the radar for so many years, he became a celebrity with the 2012 release of his book, which became a New York Times best-seller. 
 
 Defending his decision to divulge so much detail despite the secretive nature of the SEAL world, Kyle told Time that he was "not trying to glory myself." 
 
 "I didn't want to put the number of kills I had in there," he said. "I wanted to get it out about the sacrifices military families have to make." 
 
 He said that while killing did not come easy at first, he knew it meant saving lives. 
 
 "The first time, you're not even sure you can do it," he said in the interview. "But I'm not over there looking at these people as people. I'm not wondering if he has a family. I'm just trying to keep my guys safe. Every time I kill someone, he can't plant an (improvised explosive device). You don't think twice about it." 
 
 At one point, Kyle wrote, he shot a woman who was carrying a grenade while with her toddler. But he did not kill a child in Baghdad's Sadr City area who had a rocket-propelled grenade launcher. "According to the rules of engagement at the time, you could kill anyone with an RPG on sight. That day I just couldn't kill the kid. He'll probably grow up and fight us, but I just didn't want to do it. 
 
 He said the American public lives "in a dream world . You have no idea what goes on on the other side of the world. The harsh realities that these people are doing to themselves and then to our guys. And there are certain things that need to be done to take care of them." 
 
 After leaving the military, he founded Craft International , a military training company. Kyle also spoke up on current events, including accusing President Barack Obama of being "against the Second Amendment" because of his gun control initiatives, according to a video interview with guns.com. 
 
 The married father of two children established the nonprofit Fitco Cares Foundation to help veterans battling PTSD -- post-traumatic stress disorder -- get access to exercise equipment. 
 
 Littlefield, who leaves behind a wife and children, was a friend who worked to help people with PTSD, said Fitco Director Travis Cox. 
 
 In a statement, the foundation described Kyle as an "American hero" and pledged to carry on his mission. 
 
 "What began as a plea for help from Chris looking for in-home fitness equipment for his brothers- and sisters-in-arms" struggling with PTSD turned into an organization that will continue after his death," Cox said in a statement. 
 
 "Chris died doing what he filled his heart with passion -- serving soldiers struggling with the fight to overcome PTSD. His service, life and premature death will never be in vain. May God watch over his family and all those who considered Chris a true friend." 
 
 His friend, Jason Kos, offered similarly glowing sentiments, telling CNN's "Early Start Weekend" that Kyle was "a man of incredible character." 
 
 "He led by example," Kos said. "He always stopped to take time to talk to whoever was around him. Just incredibly humble, very funny as well." 
 
 Correction: Earlier versions of this report incorrectly described the military background of Chad Littlefield, who was killed with Chris Kyle. Littlefield was not a veteran.
– Chris Kyle, the man who detailed his 160-some kills during a decade as a Navy SEAL in the book American Sniper, has been killed at a Texas gun range, reports Reuters. Another man, Chad Littlefield, was also shot dead, and the AP reports that authorities have charged a suspect, Eddie Ray Routh, with two counts of capital murder. CNN reports that Routh was a fellow veteran who went shooting with Kyle and Littlefield yesterday with no one else around; the victims' bodies were discovered about two hours later, a sheriff said. "It's staggering to think that after all Chris has been through, that this is how he meets his end, because there are so many ways he could have been killed" during his military service, says Kyle's American Sniper co-author. "The first time, you're not even sure you can do it," Kyle said in a 2012 interview on how he went about focusing on a target. "But I'm not over there looking at these people as people. I'm not wondering if he has a family. I'm just trying to keep my guys safe. Every time I kill someone, he can't plant an IED. You don't think twice about it." Kyle has a forthcoming book, American Gun—A History of the US in Ten Firearms .
