Brad Parker is the author of "First On the Scene, Interviews With Parkland Hospital Doctors on the Assassination of President John F. Kennedy" which contains some of the earliest interviews with the attending doctors of President John F. Kennedy in Trauma Room One at Parkland Hospital. Brad decided to call some of these key figures in the Kennedy Assassination at the age of 19 and was able to speak with many people who gave statements to the Warren Commission and HSCA and AARB giving a firsthand account of their observations in 1963.
