-- bring the article -- and -- avionics moments ago you spoke. With the father of oak the day I did I was surprised they even got through in Georgia he must have just been in shock because he wasn't screaming we spoke on the phone for about ten to fifteen minutes. He told me that he had not expected this to happen obviously had two sons and two daughters though all four living in the US -- two daughters living in New York the suns in Boston. Tom -- -- -- we found out is a father himself the elder of the suspects who now they know is dead. Hit a three year old daughter this of course all coming from the man who told told me on the phone that he was in their father. -- or the three year old granddaughters name is -- hara. He admitted that -- and is married as well and of course obviously all concerned focus now is on his younger son. I know he believes that his sons were set up but he also had a very important message. For his son on the loose if he's listening that's right I asked -- if your son is watching right now what would she want to tell him and he said give up. Give up you have a bright future ahead of you come home task come home in Russia. But George is also convinced that his son's. We're not involved in this he says they're good boys they've never known. Two carrier train with guns or any sort of weapons at all all of this a huge surprise to you told -- his older son had been killed yes. And his response and he was in shock and what shocked me was that he said he had just spoken with the -- a few days ago after. The apparent bombings went off and he said that his sons were not there. They knew nothing about it they were very calm and said dad we don't we put these type of events but if his son was killed. If his son was killed he said that he is devastated and he thinks they did it to him. Kept calling it down the perpetrators. I'm going to give thanks very much.
