tumultuous. At the extreme west end of Main Street the motorcade turned right on Houston Street and proceeded north for one block in order to make a left turn on Elm Street, the most direct and convenient approach to the Stemmons Freeway and the Trade Mart. As the President's car approached the intersection of Houston and Elm Streets, there loomed directly ahead on the intersection's northwest corner a seven-story, orange brick warehouse and office building, the Texas School Book Depository. Riding in the Vice President's car, Agent Rufus W. Youngblood of the Secret Service noticed that the clock atop the building indicated 12:30 p.m., the scheduled arrival time at the Trade Mart.

The President's car which had been going north made a sharp turn toward the southwest onto Elm Street. At a. speed of about 11 miles per hour, it started down the gradual descent toward a railroad overpass under which the motorcade would proceed before reaching the Stemmons Freeway. The front of the Texas School Book Depository was now on the President's right, and he waved to the crowd assembled there as he passed the building. Dealey Plaza--an open, landscaped area marking the western end of downtown Dallas stretched out to the President's left. A Secret Service agent riding in the motorcade radioed the Trade Mart that the President would arrive in 5 minutes.

Seconds later shots resounded in rapid succession. The President's hands moved to his neck. He appeared to stiffen momentarily and lurch slightly forward in his seat. A bullet had entered the base of the back of his neck slightly to the right of the spine. It traveled downward and exited from the front of the neck, causing a nick in the left lower portion Of the knot in the President's necktie. Before the shooting started, Governor Connally had been facing toward the crowd on the right. He started to turn toward the left and suddenly felt a blow on his back. The Governor had been hit by a bullet which entered at the extreme right side of his back at a point below his right armpit. The bullet traveled through his chest in a downward and forward direction, exited below his right nipple, passed through his right wrist which had been in his lap, and then caused a wound to his left thigh. The force of the bullet's impact appeared to spin the Governor to his right, and Mrs. Connally pulled him down into her lap. Another bullet then struck President Kennedy in the rear portion of his head, causing a massive and fatal wound. The President fell to the left into Mrs. Kennedy's lap.
Secret Service Agent Clinton J. Hill, riding on the left running board of the "followup" car, heard a noise which sounded like a firecracker and saw the President suddenly lean forward and to the left. Hill jumped off the car and raced toward the President's limousine. In the front seat of the Vice-Presidential car, Agent Youngblood heard an explosion and noticed unusual movements in the crowd. He vaulted into the rear seat and sat on the Vice President in order to protect him. At the same time Agent Kellerman in the front seat of the Presidential limousine turned to observe the President.
