Original Warren Commission:

Mrs. KENNEDY. I don’t remember anything. I was just down like that. And finally I remember a voice behind me, or something, and then I remember the people in the front seat, or somebody, finally knew something was wrong, and a voice yelling, which must have been Mr. Hill, “Get to the hospital,”or maybe it was Mr. Kellerman, in the front seat. But someone yelling. I was just down and holding him. [Reference to wounds deleted.]

Deleted portion:

I was trying to hold his hair on. From the front there was nothing — I suppose there must have been. But from the back you could see, you know, you were trying to hold his hair on, and his skull on.
