This is interesting - now there is a woman in Southern California that claims her father was the Zodiac killer and was even with him when he killed some of his victims. She claims she heard gunshots while sitting in the car and her father would return and tell her there were fireworks making the noise. She claims to have a pair of glasses from the last victim (a cabbie in San Francisco) and has turned them over to the police for DNA analysis. Apparently law enforcement is taking her story very seriously - time will tell if either claim is true.
