Jurors Sight Past Behavior In Convicting Former Marine

STEPHENVILLE, Texas (AP) — Jurors who convicted a former Marine in the deaths of famed "American Sniper" author Chris Kyle and his friend say the killer's past behavior undermined his argument that he couldn't tell right from wrong.

Jurors in the trial of Eddie Ray Routh (rowth) told ABC's "Good Morning America" on Wednesday that he displayed a similar pattern in prior run-ins with police.

Christina Yeager says Routh had a history of becoming intoxicated and then telling responding officers he's a victim of post-traumatic stress disorder. Yeager says he often "pulled that card."

Barrett Hutchinson says Routh "knew the consequences of pulling the trigger" when he shot Kyle and Chad Littlefield at a Texas shooting range in February 2013.

Routh's attorneys had sought a verdict of not guilty by reason of insanity.
