The single-bullet theory, often derided and discredited by referring to it as the magic-bullet theory, was introduced by the Warren Commission in its investigation of the assassination of U.S. President John F. Kennedy to explain what happened to the bullet that struck Kennedy in the back and exited through his throat. Given the lack of damage to the presidential limousine consistent with it having been struck by a high-velocity bullet, and the fact that Texas Governor John Connally was wounded and was seated on a jumper seat in front of and slightly to the left of the president, the Commission concluded they were likely struck by the same bullet.
