And we want to bring in larry williams, an alum of the Oklahoma State university. You have been going to this parade for the better part of 40 years and you were one of the heroes in yesterdays tragedy. One eyewitness said they thought that this was part of th parade, from your perspective, when did you know something was terribly wrong . It hit a section of those people, it was kind of like toy army men flying if you could get this picture, like they ran a tank through it. Or a car through it. People flew in all different directions. Then the car proceeded on through the intersection and hit the Southwest Corner of the intersection, either hit a light or a curb, and thestopped at that particular point. Thats the last ti i even concentrated on the car. So, y knew right away thax something was wrong. But this all happened in a matter of seseions, did you know i know youre certified in cpr. I think it was adrenaline. My thoughts, stillwater medical management, Highway Patrol, things like that, were very good as far as getting everythihi done. But they didnt have a lot of medical people on the spot at that particular time. So what i did is, i went to several people just to make sure that they were conscious, breathing, still kind of alive, and then, thth would ask me Different Things to do, though i wasnt a professional and tried to do the best i could until the true medical people like the ctors, nurses got there so they could take over. At what point did it hit you what you just saw, larry . Well, it hit about two hours afterwards. I think the adrenaline high stayed with me for a little bit. Then, about two hours, it kind of hit me, some of the emotions and d me of the scenes and things came back in my mind. All right, larry, we want to thank you for your heroism, our thoughts and prayers go out to the Oklahoma StateUniversity Family this morning. Thank you. Sure. And again, this is a homecoming parade they billed it as americas homecoming celebration. Again, our thoughts and prayers go out to that community.
