"We kind of have an idea that maybe that's why they were at the range for some type of therapy that Mr. Kyle assists people with," Sheriff Bryant said.
Capt. Jason Upshaw of the Erath County Sheriff's Department said Routh used a semi-automatic handgun on the ex-Navy SEAL and "American Sniper" author on Saturday when he allegedly shot and killed Kyle and Kyle's friend and neighbor Chad Littlefield.
Upshaw said the Iraq vet suspect had not made any comments as to the motive for the shooting, and WFAA reported that the last known address for the suspect now boasts a for-sale sign on the lawn, and no one answered a knock on the door by reporters.
Sheriff Bryant said that the Iraq vet fled the crime scene after the shooting and went to his sister's home in Midlothian, where he told her and her husband what he had done before returning to his home in Lancaster.
Police arrested Routh around 8 p.m. in Lancaster without incident. However, he did try to flee capture at first, prompting them to use spikes laid across the road in order to halt his departure.
Travis Cox, the director of a nonprofit that helps wounded veterans, which Kyle helped found, says that Chris Kyle died as he lived because "Chris was literally the type of guy if you were a veteran and needed help he'd help you."
And if Eddie Routh's mother did ask the celebrated war hero for help with her veteran son, the four-time Iraq vet would have willingly done it based upon this video of him in January at the SHOT 2013 event, fully realizing the risks.
