Story highlights The jury reaches a verdict in capital murder case in a few hours

Eddie Ray Routh sentenced to life in prison without the possibility of parole

Stephenville, Texas (CNN) No one disputes that Eddie Ray Routh shot and killed Chris Kyle and another man. But his attorneys wanted to convince a jury he wasn't sane when he did so.
