Weiss's son, Carl Jr., an infant at the time of his father's death, has since vigorously disputed the assertion. In a 1993 interview on the NBC program "Unsolved Mysteries", he asserted that Long was accidentally shot by one of his own bodyguards. Donald Pavy, a medical doctor and first cousin of Weiss's wife Yvonne Pavy, conducted a scientific study of the case and concluded in his book "Accident and Deception: The Huey Long Shooting" that Weiss did not shoot the governor-turned-senator.
