Meyers husband rushing to the scene. Theres the animal, a block away reporter the suspects mom visibly shaken arriving during the standoff.

Police saying after an encounter with an angry driver near her home, myers grabbed her holdest son who brought his handgun to go in search of that driver only to return home where the driver shot her in the head in front of her own house. Right now, authorities here in las vegas are not saying if the person in custody is the actual shooter. The investigation, david, still ongoing tonight. And now to texas, and breaking news thein the american sniper trial. Tonight, the defense resting their case. A new look at the man accused of killing navy s. E. A. L. Chris kyle. The defense from senting images of him, right there in uniform with his mother. Far different than that other image in the backseat of a police cruiser. And now comes word that he will not take the stand. Abcs ryan owens with late developments from texas. Reporter the jury taking a twisted trip into the mind of a killer guided by a defense psychiatrist who just last year diagnosed the marine veteran with severe schizophrenia. Dr michael dunn says while american sniper chris kyle is a war hero to many it want to get the bad guy. Reporter to eddie routh on the day he killed them, kyle and his friend chad littlefield were pig assassins sent to execute him as part of pigs taking over the earth. Dr. Dunn testifying routh was so paranoid at this texas gun range, he thought shooting the two men in the back was selfdefense. He thought he was going to die and had to neutralize the threat. Routh doesnt look up as the doctor says he was insane and didnt know right from wrong. Chris kyles widow taya shakes her ned in head in disbelief. On cross examination, prosecutors point out the defense is paying this expert 400 an hour and that routh is a fan of the pig hunting reality show boss hog. And may have just cooked up this elaborate story to try to get away with murder. The defense briefly called rouths mother back to the stand so the jury could see this picture of a decorated young marine with his mom. Prosecutors took the chance to show a very different picture taken years later with his girlfriend. Rate this afternoon, eddie routh waved his right to testify. With that his defense rested relying, remarkably on the medical testimony of just one doctor. David . Ryan owens from texas. Thank you. And now, to the white house, and president obama making headlines tonight for his choice of wordshen it comes to describing isis. The president will not call this islamic terror and heres what he said today. We are united against the scourge of violent extremism and terrorism. So lets get right to Jonathan Karl tonight. And jon, the president s being careful with his words, but causing some controversy in doing so. Reporter yes, he is david. There is no question that the terrorists who make up isis and al qaeda are islamic extremists. They claim to be waging a war in the name of the koran. But the president wants to make it clear to the world that the United States is not at war with islam. In fact, today, he said the notion that the west is at war with islam is a, quote, ugly lie. As the president himself put it quote, we are not at war with islam, we are at war with people who are perverting islam. So the bottom line david, dont look for the president to change the way he is talking about this terrorist threat. All right, jon karl live at the white house, thank you.
