At the time of the Kennedy assassination Bowers worked in a railroad switch tower behind Dealey Plaza. As tower operator he had an unobstructed view of the area in back of the picket fence. The House Select Committee identified that location as the probable position of a second gunman. The Warren Commission felt Bowers' observations were important enough to depose him. Over the years investigators have related conflicting anecdotes of how Bowers died.
Some individuals claim the auto accident was a murder.
The account usually follows the line that someone killed Bowers because he saw too much, never told The Warren Commission all he knew and could have identified participants in the assassination. To me, Geraldo Rivera is a sensationalist. His staff does not take time to confirm witnesses' stories. His research consultants' veracity is usually unquestioned. The search for documentation is superficial.
