routh guilty of murdering kyle and his friend chad littlefield. jurors rejected the defense claim that routh was not guilty because he was insane when he pulled the trigger. he shot kyle six times and littlefield seven with the majority of those shots in the victims' backs. littlefield's mother also spoke after the verdict was read. >> we're so thrilled that we have the verdict that we have tonight. >> jurors took less than three hours to convict the 27-year-old man who will now spend the rest of his life in prison. one juror told "good morning america," she saw a pattern of routh's claiming insanity. >> when i say there's a pattern that we saw, it was, you know he would be -- he get intoxicated, get in trouble and the police would show up and he would say i'm a veteran, i was ptsd. i'm insane.
