Other Secret Service agents assigned to the motorcade remained at their posts during the race to the hospital. None stayed at the scene of the shooting, and none entered the Texas School Book Depository Building at or immediately after the shooting. Secret Service procedure requires that each agent stay with the person being protected and not be diverted unless it is necessary to accomplish the protective assignment.[C2-175] Forrest V. Sorrels, special agent in charge of the Dallas office, was the first Secret Service agent to return to the scene of the assassination, approximately 20 or 25 minutes after the shots were fired.[C2-176] PARKLAND MEMORIAL HOSPITAL The Race to the Hospital In the final instant of the assassination, the Presidential motorcade began a race to Parkland Memorial Hospital, approximately 4 miles from the Texas School Book Depository Building.[C2-177] On receipt of the radio message from Kellerman to the lead car that the President had been hit, Chief of Police Curry and police motorcyclists at the head of the motorcade led the way to the hospital.[C2-178] Meanwhile, Chief Curry ordered the police base station to notify Parkland Hospital that the wounded President was en route.[C2-179] The radio log of the Dallas Police Department shows that at 12:30 p.m. on November 22 Chief Curry radioed, “Go to the hospital--Parkland Hospital. Have them stand by.” A moment later Curry added, “Looks like the President has been hit. Have Parkland stand by.” The base station replied, “They have been notified.”[C2-180] Traveling at speeds estimated at times to be up to 70 or 80 miles per hour down the Stemmons Freeway and Harry Hines Boulevard, the Presidential limousine arrived at the emergency entrance of the Parkland Hospital at about 12:35 p.m.[C2-181] Arriving almost simultaneously were the President’s followup car, the Vice President’s automobile, and the Vice President’s followup car. Admiral Burkley, the President’s physician, arrived at the hospital “between 3 and 5 minutes following the arrival of the President,” since the riders in his car “were not exactly aware what had happened” and the car went on to the Trade Mart first.[C2-182] When Parkland Hospital received the notification, the staff in the emergency area was alerted and trauma rooms 1 and 2 were prepared.[C2-183] These rooms were for the emergency treatment of acutely ill or injured patients.[C2-184] Although the first message mentioned an injury only to President Kennedy, two rooms were prepared.[C2-185] As the President’s limousine sped toward the hospital, 12 doctors rushed to the emergency area: surgeons, Drs. Malcolm O. Perry, Charles R. Baxter, Robert N. McClelland, Ronald C. Jones; the chief neurologist, Dr. William Kemp Clark; 4 anesthesiologists, Drs. Marion T. Jenkins, Adolph H. Giesecke, Jr., Jackie H. Hunt, Gene C. Akin; a urological surgeon, Dr Paul C. Peters; an oral surgeon, Dr. Don T. Curtis; and a heart specialist, Dr. Fouad A. Bashour.[C2-186]
