>>> let's begin with the shooting death of the most lethal sniper in u.s. history . chris kyle was fatally shot at a texas gun range . in lancaster , texas , mark, what can you tell us?
>> reporter: lester, that gun range was chris kyle 's second home practically. we are about 100 miles east of there in lancaster , texas . this is where the suspect, eddy ralph is from, being held in this police department , already gone before a judge arraigned on two counts of capital murder . we have some video from the scene on where ralph was captured. we are still trying to get more information on him. at this point, as far as a criminal history , he was convicted of dwi last year. what we are trying to find out is motive, and what, if any, relationship he had with chris kyle and the other victim, chad littlefield. the texas highway patrol is one of the agencies investigating. here is what they say he did right after the murders.
>> he traveled back to his residence in lancaster . lancaster police department was able to catch up with him there. they took him into custody wous without incident after a brief pursuit.
>> reporter: police tell us they have a long way to go on this investigation, still trying to learn a lot more about ralph 's background. don't know if he was in the military, what kind of weapon or gun was used in this crime. we are going to be hearing from the county sheriff later today.
>> mark snyder from kxas, good to have you on
>>> i traveled to texas last february to meet chris kyle . we talked about his four tours in iraq as a navy s.e.a.l. and one shot that made him legendary among fellow snipers.
>> i saw the sergeant on top of the roof. so the movement had me zoom my scope in on him. he had an rpg, trying to hide and stay out of sight of him. about the time i saw he was getting into attack position and raising the rpg, i decided it was time to take the shot.
>> he hit his mark from 2100 yards or 1.2 miles away , an unheard of distance that stunned even him.
>> 2100 yards? lucky shot?
>> extremely lucky shot.
>> most of those he killed never saw him.
>> when you are going to war, it is not about being fair. every person i killed, i have a clear conscience of. they were actively trying to harm americans, allies or civilians.
>> he told this all in a book he wrote last year. it is so ironic that four tours in iraq, had some very close calls only to lose his life in texas . he leaves behind a wife and two children. i spoke to her at the time and talked about the fear of him being overseas. with a navy s.e.a.l., you don't know what they are doing. we lost a true american hero .
>> a terrible mourning for that family. our hearts go out
