Moments ago I had a chance to speak with a school clerk who was right there a few feet away from the gunman and talked and talked to him and kept talking until she talked him down. What did you see in his face, in his eyes? A young man that was ready to kill anybody that he could, and and take any lives that he wanted to. What were you praying? God help us all. I was just -- I was doing everything I could. I just started praying. What happened next? When did they capture him, stop him? Where were you? I was with him the whole time. I had a teacher that come in and our cafeteria manager came in. I kind of walked him through it and talked to him and told him it was okay, that we all have situations in our lives and i just went through a tragedy myself but I recovered from it and so it was going to be okay. If I can recover an open up a business, he could too. Did he respond to you when you said that? Yeah, he did. He told me okay and then he got on the phone and he was talking to some of he is family members and stuff. I just started telling him my life story and what was going on with me. So you were able to keep him there. You were able to hold him there for a while? I held him the whole time. He asked me did he want to go outside and start shooting again. How did you know it was finally over? Because I asked him to take -- to put all of his weapons down. I had him to take everything out of his pockets, to empty his pockets, to put all the ammunition -- he had a backpack full of ammunitions. He had all the magazines in his backpack, some of was in his pocket. I had him to empty everything, put the gun on the table, take his wallet off, everything. I told him to lay on the floor and then I told the police that he was giving himself up. I just talked him through it. He did it, he got down on the floor? He got down on the floor. When the police officers came had he was actually laying on the floor with his hands behind his back. What was the prayer you said when it was all over? Thank you, jesus. And we also thank her for the safety of those children. I want to bring in senior justice correspondent, pierre thomas. 8 months since newtown. Reporter: These incidents are becoming too common. Thankfully none as bloody as newtown but there have been at least 8 cases where shooters have been on school campuses since the massacre in connecticut. They ranged from shooting on college campuses to middle schools and high schools. Diane, some schools are bringing in more security but many schools simply don't have the resources. Only 43 percent of schools have a security officer once per week according to a 2009, 2010 survey by the national education for statistics. Our children are vulnerable. Thank you so much, pierre thomas.
