STEPHENVILLE, Texas — Attorneys mounting an insanity defense rested their case Thursday in the trial of the ex-Marine charged with gunning down “American Sniper” author Chris Kyle and another man.

Eddie Ray Routh did not testify during his trial for capital murder in the deaths of Kyle and friend Chad Littlefield at a shooting range two years ago. Jurors heard from a forensic psychiatrist who said Routh has schizophrenia and showed signs of psychosis in the weeks leading up to the slayings.

Prosecutors, who argue that any history of mental illnesses should not absolve Routh of being accountable for the deaths, indicated they would call two rebuttal witnesses Friday, The Dallas Morning News reported, an indication that the jury could soon have the case.
