chad littlefield. the jury rejected routh's plea of not guilty by reason of insanity after three hours of deliberation. a sad epilogue to the story of chris kyle. the larger than life character played by bradley cooper in the oscar-nominated blockbuster film "american sniper." >> i just want to get the bad guys. >> reporter: we know he pulled the trigger and killed kyle and littlefield. that was never in dispute but it the question after weeks of testimony from almost 30 witnesses, it all boiled down to this. was routh a cold-blooded murderer or was he so mentally ill, he didn't know right from wrong when he killed the men? the jury swayed by the prosecution voted guilty. >> confinement for life in the texas department of criminal justice without the possibility of parole. >> reporter: chad's mother judy littlefield briefly addressed the cameras. >> we have waited two years for god to get justice for us on behalf of our son and as always, god has proved to be faithful.
