During my countless hours thinking about the case, the Zodiac killings came to my mind also, but a few small points:
1. The Zodiac seemed to operate in a area between San Francisco, Vallejo and Santa Rosa (if you believe Greysmith that he was involved in the I-5 co-ed murders) - all areas north of San Francisco. Anna was taken from an area thirty miles south of San Francisco.
2. The known Zodiac killings included only adults who were killed where they were found, not kidnapped and taken elsewhere (Kathleen Johns the possible exception). The Zodiac did threaten to shoot children getting off of a school bus, but no evidence exists that he ever killed any children.
3. Leigh Allen, the suspect that several LE types believed to be the Zodiac, was in fact a convicted child molester, but he appeared to abuse those he knew, either through his activities or family and friends. I do not believe that he ever was accused of kidnapping any victim.
I have briefly considered several of the famous cases that happened in the 1970's Bay Area for any possible link (kidnapped by the People's Temple and died in Guyana - that's why no body was ever found?). I quickly realized that none of them made much sense. I always came back to Anna's father and his mentor.
