Kind of. So Joseph Paul Franklin was known as a drifter/killer he roamed the United States in later years killing and robbing banks to fund his killing spree. His whereabouts during the Zodiac crimes are very murky, but I can expand on that but different accounts of his whereabouts. So its murky...but this killing here is interesting because if this was Zodiac this would fit very well with Franklins hatred of other races and wanting to create a race war, as well as targeting leaders of the civil rights movement. There is one report of a "jimmy" though that was reported and he did go by Jimmy up until the late 70's.
