Longer. How cosby is responding tonight. Good evening and thanks for joining us on this sunday evening. Im cecilia vega. We begin with the breaking news. The white house confirming the death of american peter kassig at the hands of isis, calling it an act of pure evil. The terror group revealing the killing in one of its most ruthless and taunting videos yet. Kassig, the 26yearold aide worker taken captive in syria more than a year ago, and this man with a british accent who once again appears to be the executioner, jihadi john. Tonight, the desperate search for clues in the gruesome video and the race to find other hostages still in captivity. Martha raddatz joins us in a moment. First abcs chief investigative correspondent brian ross is here with the latest, brian . Good evening. The video turns up the heat on the brutal isis leaders, including the team of sadistic british recruits who despite the u. S. Air strikes have found a way to once again shock the civilized world. For isis, it did not seem to matter that peter kassig converted to islam. Had come to syria to help, not fight. We each get one life, thats it. Reporter but there was no mercy for peter kassiged a todays propaganda video made clear. A masked man with a knife appeared, claiming to be in the city of dabiq with kassigs severed head at his feet. Referring to him only as a former u. S. Army soldier. Here we are, burying the First American crusader in dabiq. Reporter it appeared to be the same man with a british accent and voice seen in previous isis videos, known as jihad john. The purported executioner of others. It appeared to the same person. And obviously inside the government, working very hard to exactly identify him. Reporter he appears elsewhere on the video, where he gives order to behead 16 men. Describes as syrian soldiers. Unlike other videos, the other isis fighters all show their faces as they commit the murders, and a potential intelligence bonanza for u. S. And european officials trying to identify and track them. And also unlike other videos, jihad john makes no attempt to hide his location with clear obvious landmarks with buildings, roads and farmland in the background, seemingly to taunt the usa and president obama, eager i awaiting the armies to arrive. Earlier today, his parents said they are heartbroken, saying their son had lost his life as a result of tries to ease the suchering of the Syrian People and trying to east their suffering. And u. S. Officials fear they have not seen the worst yet. It still holds another u. S. Worker, a young female aide worker who is facing the same fate as peter kassig. I want to bring in now abouts chief Global Affairs correspondent martha raddatz. These numbers are absolutely staggering. About 800 air strikes so far against isis. Why arent they working . Well, the air strikes, which have cost about 1 million an air strike, a meant to hold back isis from taking over more towns, more territories. And they have had success with that. But that is a temporary fix. You need Ground Troops to try to do anything more. In the meantime, videos like this, the atrocities will continue. Because isis knows it has a horrifying effect but its also a recruiting tool. You mention the iraqis, is it inevitable we will see american Ground Troops on the ground there . When you think about it we already have boots on the ground which will grow toe about 23 3,000 in the coming months as trainers and advisers and we could have more after that. We are not going to have an invading force there. But the key is whether the u. S. Troops will be with the iraqis on the front lines when they try to take back some of the towns. And the chairman of the joint chiefs says he could indeed request that, and that could make the involvement a lot more dangerous. Thank you. And an extraordinary move at the state department after an apparent attack by hackers. Shutting down the classifying email system. The breach possibly linked to an attack on the White House Computers last month. And hackers tied to the russian government. The prime suspects in that case.

And lake superior, ice already on the shorelines, nearly two weeks earlier than last year. And rob joins me. We all remember how brutal last winter was. That has people nervous.

Well, yeah, youre a rapist, so reporter back in 2006, cosby settled a civil case with a woman who claimed he drugged and assaulted her. The settlement did not include an admission of guilt. And this woman, saying he allegedly drugged and raped her in 1985 when he was helping her with her career. He really knew how to zero in on on my insecurities and vulnerabilities. Reporter she was expected to testify in the 2006 case, says she never filed criminal charges against cosby because no one believed her. When i went to the lawyers office, he laughed at me, and treated me like i was delusional. Basically called me a liar. Like, are you kidding me . Who is going to believe that . Bill cosby . Dr. Huxtable . Reporter he canceled interview, including an appearance of David Lettermans show. The statute of limitations for her claim has passed. She is encouraging others to do the same.
