"American Sniper" trial jurors see videotaped confession

STEPHENVILLE, Texas -Jurors have seen a videotaped confession by the former Marine accused in the fatal shootings of "American Sniper" author Chris Kyle and his friend.

The tape played Monday sheds more light on Eddie Ray Routh's mental state shortly after the killings.

The 27-year-old has confessed to the February 2013 slayings but has pleaded not guilty by reason of insanity.

Texas Ranger Danny Briley testified Monday that the shootings were intentional because Kyle was shot six times and his friend, Chad Littlefield, seven times, CBS Dallas reported.

During Monday's testimony, a police video showed Routh face down on a table in a police conference room when a Texas Rangers interrogator comes in to talk to him.

In the interrogation, Routh confessed to the shootings: "I knew if I didn't take out his soul he would take mine." Routh said he shot Chad Littlefield before shooting Kyle.

Defense attorneys say Routh was insane when Kyle and Littlefield took him to a shooting range to provide support and camaraderie. Prosecutors say he knew his actions were wrong and should be convicted of capital murder.

In the confession, Routh said of Kyle, "If I did not take down his soul, he was going to take down mine," according to The Dallas Morning News.
