earlier i spoke with one of kyle's friends, jason kos, about the man he called a war hero. >> he and a friend took a marine that was suffering from ptsd to a gun range to shoot and as a way that he always did giving back and, you know, it was certainly him taking his time to help, again, help war heroes. >> he had quite a reputation in the field as one of the most lethal snipers out there. how did he handle that? >> you know, he viewed, chris viewed it as his job and he was protecting his brothers, frankly. he as a man was quite contrary to that because he was incredibly loving father and charismatic and really caring person. so, it's quite a contrast from what he did as his job and tours of duty. >> we are not naming the suspect in this case, but do you know if there was any connection at all, or believed to be any connection between chris kyle and this suspect? >> no, ma'am, i have no idea. >> was this shooting range somewhere that he would frequent regularly? where the shooting occurred? >> i believe so, yes. i think he was familiar with the location. >> and can you tell me about
