STEPHENVILLE, Texas (AP) - Several days of evidence have focused on the mental health of the former Marine accused of killing "American Sniper" author Chris Kyle and his friend.
The capital murder trial of Eddie Ray Routh is set to resume Monday in Stephenville.
Criminal law experts say the case hinges on whether the defense can prove that Routh was insane at the time and did not know the February 2013 killings constituted a crime.
Defense attorneys say Routh, who was taking anti-psychotic medication, was insane when Kyle and his friend, Chad Littlefield, took the ex-Marine to a shooting range.
Prosecutors have said that Routh was a troubled drug user who knew right from wrong.
